May 16 2016:


Added ability for RTM Player to cooperate with RTMonitor on quad boards.  This is enabled by the Enable Mutliple Applications registry values for both applications.  In this mode ClearView uses framestores 3 and 4 and RTMonitor uses framestores 1 and 2.  It may also be necessary to reduce memory usage of both applications by setting the Memory Usage Percentage registry values for both.


Fix for IPRecord input into YCbCr 10 bit image format when then input is only 8 bit.  This requires the latest IPRecord (version 0.8.4.1).


Changed the sequences file backup scheme so that the most recent backup is alway .000 with .009 always being the oldest.


Fixed an audio sync issue with the Dual Player.


In the full ClearView loading DMOS logs created in frame mode for interlaced video formats were loading incorrectly if the config DMOS Field/Frame mode was set to auto in which case the logs were erroneously interpreted to be in field mode and the data was graphed incorrectly.  Now the frame mode setting from the log overrides the config setting.  This is also fixed for Jnd.

Fix for preview glitches when using Dual Output with 4K video.  This fix is for all Players.





April 27 2016:


Fix for enabling Metric Window Overlay not being saved in config dialog.

Fixed a crash which occured when loading a metric log when the sequences were missing.


Fixed preview problems for the Dual Player.


Fix for pausing sometimes having corrupted output when autocirculate does not start correctly.  This has been traced to not having any frames in the hardware queue when autocirculate is started.  The logic has now been changed to not start until both streams have at least one frame in the hardware.


Changed RTM Player to not default to being in dual output mode which prevents side by side from working.  Now in order to do dual output, the Use Multiple Outputs option must be enabled.




March 11 2016:


Added v210 to RGB 10 converion for file import.


Fixed A-B for YCbCr 10 bpc when zooming.

January 7 2016:


Added 2x2x2160p 8K video formats to the CVServer videoFormat command.  This requires a new CVServer.exe.


Added a stop command to be issued once metric processing is completed.




January 6 2016:


Fixed the long delay between jogging/shuttling and seeing the output.


Fixed jogging not moving the shuttle position.




January 5 2016:


Fixed shuttling problem when speed is not 1.0 the sequence frame number were incorrectly mapped to the shuttle position.


Added registry setting to enable/disable the Desktop Output Module.


Added warning when the file import last frame is automatically reduced due to not enough available disk/memory space for the entire file.


Desktop Output Module is now resizable.


Added license checking for MediaRead C interface to avoid trying to load frames when it is unlicensed.


Added check for file import to look for a conflict between the source file and the destination sequence which could happen if the source file is in the destination library and the source file has no extension (as do our video sequences) or is a .hdr file.






December 22 2015:


Currently disabled Desktop Output resize option until working better.  




December 16 2015:


Changed from DTMediaRead RPC interface to 64 bit C interface.  This requires using the libDTMediaRead.dll.  Added a registry option (Use MediaRead Color Space Conversion) to allow MediaRead to do Color Space Conversion.


Added Desktop Output Device.  This requires SDL2.dll.


Fixed frame counter not incrementing for viewport A when using the ClearView Dual Player.


Fixed dual output router configuration on a single Kona 4.

Added multi-threading of Temporal and Spatial metrics.


Added Rec BT.2020 color space conversion.


Fixed a bug previewing when using ClearView dual player with 8K input.





November 5 2015:


Getting output/preview to update after changing enable LUT or switching LUTs required jogging or some other action to force reading new frames.  This has been fixed so that output/preview frame automatically shows the change.


Getting output/preview to update after changing Force 601 required jogging or some other action to force reading new frames.  This has been fixed so that output/preview frame automatically shows the change.


Added support for side by side modes on ClearView 8K.


Fixed dropping metric log files not working for 8K video formats which require Broadcast Boards 1 and 2.  Now we selected the proper output module based on the video format.





October 30 2015:


Added multi-threaded PSNR.


Added support for 8K recording using two Corvid88 boards each running dual channel 4K.




October 15 2015:


Added 8K playback using two Corvid88 boards each running dual channel 4K.  Added a new video file format which saves video

in 4K quadrants enabling faster playback.  There are new video formats for 8k: 2x2x3840x2160.


Fixed playlist playback for 4K playback when using two Kona 3G Quad boards each in dual channel 1080p playback.

CVServer change to close socket on send and recv errors.


CVServer change to add log entries for connecting/disconnecting.


Fixed special case of file import workaround for importing into v210 720p format.  Now uses 2vuy instead of RGB when v210 read format is unavailable.


Removed unused file import code for h264, mpeg4 and DirectShow.


Now when a sequence is imported by FileImporter and the output video format is a 2x2x1080p format, ClearView will translate this format into 4x1080p format for systems that dont have the 2x2x1080p formats in order to automatically select a compatible video format when the sequence is assigned to a viewport.  This will also work if the reverse is true.





September 8 2015:


HD playback on a quad board now has SDI Out 2 hooked to FS 1.





September 2 2015:


Fixed Jerky preview of 4K playback using the No Video Output Module.




September 1 2015:


Added support for Corvid 88 boards for single playback and record and in/out recording.


Also added minimal support for Corvid 44 boards (currently used in the same manner as a Corvid 22).


Changed MaxBuffers logic to always use the registy value (if non-zero) subjected to min (80 or 160 for dual 3G Quad Mode) and max (320) limitations.


Removed broadcast hardware calls in config dialog when no broadcast hardware is installed.


Fixed an import problem where if the previous import failed due to missing frames at the end of the file, the error flag was not reset (unless reset was exlicitly selected) and re-importing failed immediately.


Changed broadcast hardware buffer allocation to maximize buffer usage.


Fixed problem doing single frame alignment when the sequence in B was less than 3 frames in length.  No we do not treat this as an error in verification and let the alignment continue.





August 12 2015:


Changed DMOS logs to show Min/Max/Avg C instead of Cb.




July 31 2014:


Updated license to version 8.3.

Fixed a preview update issue when using Broadcast 4K sometimes the preview would not update when sequeces were asigned to a viewport or one of the view mode buttons was pressed.





July 13 2015:


Fixed error with imported timecode having an incorrect value for seconds.





July 9 2015:


Added a config option to delete files to the recycle bin.




June 30 2015:


Fixed a problem when recording CV Output and 16 audio channels is enabled.  The recorded sequence has audio in 16 channel format, but the sequence header was set to only 8 channels.  Now it is set to 16 channels.


Added api support for SnapShot command.  Also added help for WaitInterval.  CVServer help is now alphabetical.  Note this requires the new version of CVServer.

Fixed problem with Quicktime mov export timecode track.  Starting frame number was incorrect.





June 11 2015:


Fixed field order playout for NTSC when in Field Mode F1F2 Alternating mode.  We now play F2 (bottom field) first.




June 9 2015:


Changed aFreq and PEAQ scores for mostly silence from 1.0 to 2.0 and scores for spikes from 2.0 to 3.0 to match RTMonitor.


Fixed black lines on broadcast output during playback when in one of the side by side modes and there is a non-zero Spatila Offset for Y.





June 5 2015:


Fixed the long time it takes to load very large audio metric logs.


Fixed a problem with doing exhaustive alignment on sequences with vanc enabled.


Added timecode track to exported Quicktime mov files when timecode is enabled and the sequence has timecode.  This requires a new version of cvMovExportProc32.exe.


ClearView installer now runs regsvr32 on VC_DDP_AudioDecoderFilter.dll since IPRecord no longer installs and registers this filter.





June 1 2015:


For Metric logs with broadcast output modules we no longer specify the module number.  When reading the metric log we do not change the broadcast output module unless necessary.


Added support for importing VITC or LTC via ClearView import using Drastic MediaRead.





May 28 2015:


We now prevent the application from being sized beyond the initial startup size in order to prevent the appliction from being stretched to full screeen.


Fixed broadcast recording with rp188 timecode.  Now it is recorded correctly.


Added support for exporting 16 channels of audio in .mov and .aiff files.  Also fixed a problem when exporting fewer audio channels if the sequence had 16 audio channels.


Changed the vcRedist for VS 2008 to SP1 version which does not leave files behind after running the ClearView installer.





May 18 2015:


Changed the default Max Buffers value from 40 to 80 for cases when there is no value defined in the registry.  If there is a value in the registry then that value will be used.


Changed shuttle page size to a smaller value which helps to more accurately select the position by clicking on the shuttle bar.


Fixed problem when doing dual output on a single Kona 4 or 3G Quad, the audio from channel 1 was playing out both SDI Out 3 and SDI Out 4.  In this case SDI Out 4 should have had the audio from channel 2.

For single or in/out recording 4K formats we now select the broadcast board that is not being used for playback.





March 20 2015:


Added Exhaustive Alignment for creating a new reference sequence to match test sequences with dropped or duplicated frames.


Fixed problem with Loudness/True Peak calculations where some scores were showing as -1.#INF.  This requires a new AudioLoudness.dll.


Now explicitly turn off audio loop thru for all inputs even when no audio in playback.

Explicitly enabling channel 1 for playback and record since it may have become disabled by RTMonitor.




March 6 2015:


New CV client and Server which support a wait time interval.  For synchronizing commands across multiple units.


Made all message boxes System Modal.


On 4K broadcast boards we now loop on checking the input signal formats which is necessary when changing from playback to record mode.


Fix for glitchy previews while playing on 4K system.


We now automatically select different libraries when doing synchronized Broadcast/IP recording.






March 2 2015:


Added an error message to notify the operator when recording Broadcast input with Dolby decoding enabled, but no Dolby exists in the signal.  Now when record is pressed it will put up an error stating that it has timed out trying to decode dolby audio.





February 27 2015:


Fix for flickering previews.


Switched from 11.3 sdk to 12.1 sdk.


Fixed problem with HDMI output when switching to 1080p formats after playing 4K formats.

February 26 2013:


Fixed issue on 4K systems where assigning a sequence to a viewport would not play the first frame to the broadcast outputs.


Now setting 4K HDMI output to YUV/RGB based on current image format.  This should hopefully fix HDMI 4:2:0 output. Waiting to test.


Fix for 4K in/out recording using 10 bit YCbCr - would sometimes drop frames when preview was first hit causing a stop. For this case we do not raise producer thread priority.


Fix for audio playback glitches for 8 channel audio when Enable 16 Audio Channel Mode was enabled.


Fix for audio from previous sequence being played when previous sequence was HD and current sequence is 4K.


Added v210 support to VancUtil.





February 19 2015:

Changed 4K Broadcast HDMI output settings to use 3840x2160 HFR format for high frame rate (50 - 60 Hz.) 4:2:0 4K playback.


Fixed slow previews on ClearView Players by removing throttle mechanism.


Fixed jerky shuttle when scrolling - we now do not try to set the shuttle position if in the middle of scrolling.


Fixed jumpy shuttle when jogging in reverse.





February 13 2015:


Fix for audio alignment when using Dolby decoder.





February 11 2015:


Fix for dual input on a single quad board - now using audio subsystem 2 for the second input.

Fixed jumpy frame counter/preview for No Video Output mode.


Fixed flickering frame counters.





January 27 2015:


Changed version to 8.2.


Fixed a problem where broadcast recording was not decoding Dolby audio until RTMonitor was run first.  Configuring the AudioControl2 register to support 8 channel audio fixes this problem even though we are only using channel 1.


Added config option for 4K HDMI v.2 Output to use 4:2:0 full frame rate output for 50, 59.94 and 60 Hz. instead of 4:2:2 at half frame rate.


Fixed a lip sync problem with Dolby audio recording.





January 23 2015:


Changed code for creating a side by side split mirror frame for YCbCr 8bpc frames.  The code now maintains pixel pairs since the image format is 4:2:2 which means Cr and Cb are shared for 2 pixels.  The old method which tried to overcome this limitation would have visual artifacts particularly when there was a horizontal shift of an odd number of pixels.


Fixed crash caused by launching more than one instance of the Library Manager.  We now limit to one instance.





January 16 2015:


Fixed problem where SDI audio was not being recorded for single input unless RTMonitor had been run first.  This was due to a Broadcast driver/firmware bug which requires the audio source select to be set for channel 2 even though only channel 1 is being used.





January 13 2015:


Broadcast record tab now shows "Detected Signal: Invalid" when the input signal changes or goes invalid while previewing or recording.





January 8 2015:


Fixed crash which happens when playing after loading a .dmos log when there are -1.0 (uninitialized) values in the log.


Added workaround for correctly importing 4K ProRes 10 bit mov files.

Removed Direct Show Import option.


Now linking to IPRecord.lib from SVN.


Disabled writing to C:\MovExportDbg.txt file in cvMovExportProc32.exe.





November 26 2014:


Fix for VC_DDP_AudioDecoder and LicenseValidation.dll which caused ClearView to not work when RTMonitor was not licensed.  This was caused by the Dobly decoder using the wrong application code when calling the LicenseValidation.dll.


Fix for crash in No Hardware Output mode when the custom format had a frame rate of 0 Hz. which caused a divide by zero error in the preview code.


Added UI and registry support for Audio Gap and Spike detection.





November 19 2014:


Fix for In/Out recording where preview shows the VC Logo instead of the playback video frame.  This is due to the logo being already in the playback hardware buffers.  The first frame of the playback video was sent to the board, but the autocirculate delay was not reached so the board had not started autocirculating yet.


Fixes for dual IP recording.  The second input sequence name was not being used and hence we ran into file open issues after recording since the recorded file had the wrong name.  We were also seeing similar file open errors after recording due to duplicate calls for creating a sequence when the duplicate call happened after we automatically changed the sequence name in preparation for the next recording.


For IP recording, we now wait 3 seconds after IPStreams have started before enabling the record button to prevent capture of frozen frames which sometimes occur when the IPStream is first started.





November 17 2014:


Added a new registry DWORD Value: Dropped Frame Timer Seconds.  If set to a non-zero value this will inhibit reporting dropped frames on playback until the time is reached.





November 13 2014:


Fixed Frame Counter B not working in Side By Side Modes when playing using broadcast output.





November 12 2014:

Fixed problem where the preview and/or frame counters would continue on for several seconds after pausing.


Some more unfruitful changes for 3:2 pulldown during import.


Added support for the new VC_DDP_AudioDecoder change for initialization.


Some changes to support dual 1080p B input on a single Kona4/3G Quad board.

Fixed problem importing mov file with Dolby Digital in audio stream.


Added support for pass thru of PCM data when Decoding Dolby.


Added changes for Dual Link (SMPTE 372) input on 3G Quad boards.


Made changes to use 3:2 pulldown support in MediaRead (this is still not working with the current MediaRead).


Fixed problem where second dropped frame value was not being reset when previewing dual record on broadcast record tab.





October 20 2014:


Added support for Dual Link (SMPTE 372) input on a single 3G input for Kona4 - needed to connect SDI In 1 DS 2 to FS 2.


Some fixes for Split Mirror and B only View modes when Spatial X offset is an odd value.  Also fixed A only view mode when X offset was negative.


Some changes regarding decoding Dolby Digital audio.


Added Dolby Digital Audio decoding to file import.





October 9 2014:


New license for version 8.2 has Movie and Dolby Audio Decode options.  Removed DVI Input.  This build requires VC_DDP_AudioDecoder.dll.


Removed Broadcast Record Down Convert option (was only supported for LH boards).


Removed Big Endian Audio Config option - MediaRead always gives us Little Endian.


Added Dolby DDP Audio Decode option to Config dialog.


There are new versions of cvLicenseCreate.exe, ClearViewLicense.exe and LicenseValidation.dll.  CVLicenseCreate now copies the license to the clipboard.






september 29 2014:


Added support for 3:2 pulldown in anticipation of a new MediaRead from Drastic which will support this on import.


Added reverse DMOS to MS-SSIM routine as a sanity check and to allow for plugging in DMOS values in the debugger to get correlation of MS-SSIM to DMOS values.


Fixed crash after Movie processing when number of frames exceeded 480.


Made some changes to accomodate 16 Audio Channel Mode - number of audio channels imported and fixed allocation of Audio Sample Buffer to support 16 channels.






September 4 2014:


Added Repeat checkbox to Single and Dual Players.






August 28 2014:


Reversed Movie log column header so that Spatial and Temporal scores are properly labelled.


Fixed problem where the first 8 Movie scores where showing negative values sometimes.  These score are not defined since the metric does not produce scores until the ninth frame.  We now put the first available scores into these first frames.







August 27 14:


Fixed RTM Player UI problems where Playback and Metric Tabs where not positioned correctly causing some fields to be cut off.


Added Movie Metric back in.


Fixed problem where Movie graph was not created until either the Temporal or Spatial radio buttons where selected.


Fixed problem where quad HDMI output would only display the upper left quadrant after recording.  Now all four framestores are set to playback correctly.






August 14 2014:


Fixed problem on quad boards where selecting 2 audio channels for HDMI output actually selects 8 and vice versa.  Now selecting 8 so the router actually shows 2.





August 12 2014:


Fixed problem where aborting import of a file with audio fails to delete the .aud file and then a susequent import puts the audio into the existing .aud instead of into a new .aud file.






August 11 2014:


Fixed missing audio on SDI out 2 when playing a single sequence on a Corvid22.






August 6 2014:


Fixed problem where when a sequence is assigned to a viewport using the No Hardware Video Output module and the current video format is saved with the sequence causes a problem when assigning this sequence to a viewport when using the broadcast output module.  This is because the format of the video format strings is different for the different output modules.  Now we translate the saved format into a proper broadcast format which allows the sequence to be assigned to the viewport without complaining that the format could not be selected.





July 22 3014:


Fixed crash when selecting broadcast in/out record mode on Kona4 systems. This was caused when calling deprecated api method to enable/disable framestore 2.


Fixed routine which determines whether to playback using channel 2 when in in/out record mode. It was always returning true.






July 21 2014:


Fixed playback problem when using multiple outputs and the current record mode is in/out and the out is using channel2 (true for some boards).


Fixed crash when dropping large .yuv file on ClearView.  Crashed on getting audio fourcc.  Just removed code for now since it was not being used anyway.  Also fixed a crash while importing this same file.



Fixed problem where sequence thumbnails were not showing with sequences imported with FileImporter unless library was reloaded.






July 15 2014:


Fixed problem where 4X and 2x2x video sequences when exported always create files with 29.97 frame rate.  Now these video formats are handled correctly.





July 10 2014:


Removed segmented DMA mode of operation for 2x2 dual quad modes.  This fixes a video corruption problem, but does reduce performance for side by side view modes.


Now stops recording in addition to playback when dropping frames on playback during in out recording with abort on drop enabled.


Fixed preview mixup (stays in input preview mode) when single broadcast record, preview then stop.  Needed to force stop on playback to get preview to switch back to playback.





July 8 2014:


Preview timer changed from 16 to 10 msec (broadcast and No Video Output). Preview using a 33 msec timeout.


Made warning message more specific about having to change video or image format when assinging a sequence to a viewport.


Fixed inconsistent data errors about saving libraries when Reset is selected after recording Broadcast/IP dual recording and manually stopping.


Now IPRecord record tab record and stop buttons dont enable until the IPRecord graph has started - this should fix the green recordings.





July 3 2014:


Fixed preview problem where sometimes the preview does not match the output frame and frame counter.






July 1 2014:


Added a warning dialog and prevent the IPRecord config dialog from being launched when the the broadcast output is set to a 4K or 2x2 format.


Added audio spike detection to the aFreq metric.  If a spike is detected the score is 2.






June 24 2014:


Fix for DMOS/SSIM.  The last few frames were showing a DMOS score of 4 when the SSIM score was -1.  We now use -1 for DMOS value when SSIM score is -1.  Also we fixed a problem with the last few frames not being scored due to having an invalid size because when we recreated the metric for the remaining frames we did not reinitialize the the VideoFrame structure used in the SSIM.dll.  The new SSIM.dll is not required, but it does have extra error checking and debugging information in it.


Fixed some UI tab dialog positioning and size problems to fix little cosmetic issues caused by changing from popup to child dialogs.






June 20 2014:


Fixed problem with single and dual player, when IPRecord tab is selected an erroneous message appears stating that the user is "Attempting an unsupported operation".  This pevented using IP input.


Changed all tab dialogs (record, playback parameters and objective metrics) from WS_POPUP to WS_CHILD.  Now we ignore move messages since the parent window handles the movement for us. We now position the dialogs after creation.  This enables large previews to work without having the tab dialogs appearing over the preview window.





June 17 2014:


Added gap detection to aFreq Metric - there is a new registry DWORD value: Audio Metric Gap Min Samples (set to 0 to disable (default)).  Currently using 480 to find 10 msec gaps.  





June 13 2014:


Now showing threshold line in audio metric graphs.


Fixed problem with audio sample graphs for A/B and combined graph modes.  When audio samples were at the maximum level it caused graph to be distorted.







June 10 2014:


Fixed crash when threshold failure overlay is enabled for NTSC video playback.


Fixed playback from first or last frame when playing and then first or last frame is selected and then play again.  Used to play from current spot instead of first or last frame.


Added a preview buffer array for synchronous preview mode (No Video Output or Broadcast output except quad formats). This helps with smooth playback to the preview from the beginning of the video.


Now ignoring IPRecord messages when IPRecord config dialog is active.


Fixes for Synchronous IP/Broadcast recording.






June 3 2014:


Fix for importing mp4 file with 16 bit audio using Drastic. Now audio is correct.


Changed preview frame timer from 33 to 16 msec for broadcast playback.


Changed shuttle to set all intermediate positions for smoother playback.






June 2 2014:


Added E-E support using HDMI output on Kona 4 systems when in 4X (quad) formats.


We now force stopping the output when preview is selected during in/out recording.  We then restart output if it was previously playing or paused.  


Added API support for setting/getting the Broadcast/IP record sync setting.


Added API support for snapshot.


Added API support for synchronous Broadcast/IP recording.


Fixed problem where DMOS was showing failures for frames beyond end of sequence. Threshold failures could exceed the number of frames if the total frames was not a multiple of the number of threads used.


Fixed problem doing in/out recording on quad boards caused by erroneously setting all ports to be inputs.

Now framestores and ports are properly enabled.  Note we now playback on Framestore 3 if doing in/out recording on a single quad board.  This is because FS 2 cannot be connected to port 3 due to space limitations in the firmware.


Fixed problem where PEAQ scores were incorrect if audio needed to be aligned.


Changed DMOS threshold failure determination to be only when greater than threshold to fix erroneous failure when threshold is 0 and the score is 0.


Fixed problem on the Jnd dialog where selecting Spatialize, Normalize or Align checkboxes caused the On/Off checkbox to be deselected.






May 21 2014:


Fixed problem when loading .dmos logs where the failure counts were inaccurate due to reading the wrong columns of data in the logs.


Fixed Jnd log creation where failures are logged when the score is 0 and the threshold is 0.  This should not be a failure.


Removed Movie video metric tab for 8.1 release.






May 19 2014:


Fix for crash when importing .yuv files with audio import enabled.  


For Kona 4 we now set HDMI Mode on HDMI output widget.


Fix for getting NTV2 Requested resource is in use error message when external sync is selected and the external sync signal is incompatible with the output format.


Removed startup warning message when the current analog output format is incompatible with the video output format.


Fix for jogging when sometimes preview window is not current with output frame and frame counter.







May 6 2014:


Made a 32 bit build of ClearView.exe.  This depends on version 0.7.11.7 IPRecord or later. Note that this version does not have a movie.dll and the movie metric is disabled.  It does have a new AddbackSubtractor.dll.


There are now two builds, ClearView.exe is made with the version 10 sdk.  ClearView_11.exe is built with the version 11 sdk.


Now setting HDMI output video standared for quad formats.






May 4 2014:


Changed swapping for dual output using a single quad board from at the router to at the channel used to create the playback object.






May 2 2014:


Fix for dual output on a single quad board - outputs werent being swapped when swap was enabled.






May 1 2014:


Added support for Kona 4 board (only available with version 11 sdk builds).


Dual Output on a single quad board now uses outputs 3 and 4.


Disable OUtput/Input modules 1 & 2 if system has 2 Kona 4 boards.


Fix for dual input previewing of input 2.






April 14 2014:


Fix for overlay not working properly when playing playlists.


For broadcast playback on 3G Quad and LHi boards, we now set the HDMI output to 2 audio channels by default.






April 7 2014:


Fixed crash when getting results for Movie Metric.






April 5 2014:


Fixed frame counters not responding when paused in broadcast output.






April 4 2014:


Movie Metric graphing and logging now working.  Added radio buttons for switching between Temporal and Spatial Scores. Min/Max/Avg scores.  Increased score precision to 4 decimal places on UI.






March 31 2014:


This now requires Movie.dll.  Movie tab is now functional, but on/off is currently disabled.


Fixed IPRecord dual record problem where after capture one of the files was missing.


Fix for IPRecord Custom Format problem with non-integer frame rates.


We now have IPRecord Video and Audio GetBuffer timeouts set to 10 seconds by default.


Added config option for stopping playback when doing in/out recording.  The default is to stop and restart playback from the beginning.


Fixed crash when loading .dmos logs.


Fixed slow preview update when shuttling/jogging when MaxBuffers is a high value.





March 24 2014:


This depends on IPRecord 0.7.10.7 or later.





March 18 2014:


Fixed a problem when playing 2x2x1080p formats with the YCbCr 8 bpc image format caused horizontal lines across the middle of the frame.






March 5 2014:


New version of AddbackSubtractor.dll.  


Performance improvement to dual quad playback render and non-render modes.  Using segmented dma from the render buffer eliminates need to split frame into quadrants.


Now requires IPRecord version 0.7.9.18 or later.


Now support playback and recording RGB video formats on a quad board using dual link.  SDI ports 1 and 2 are now setup correctly as inputs and ports 3 and 4 are setup as outputs.





February 23 2014:


New Dll added - AddbackSubtractor.dll.  Increases performance for A-B with Addback for YCbCr 10 bit with no zoom.


For quad boards and LHi boards with HDMI outputs we now Set Audio Enable for stereo mix present.


Added support for simultaneous Broadcast and IP Recording.


Fixed problem where a warning message stating that the external reference was incompatible with the playback video format would come up when in fact the reference was fine.  This happened when the reference was set SDI inputs.





February 11 2014:


In cases where the system only reports 4 processor cores, but we have 8 logical processors we now spawn 8 instead of 4 threads when doing YCbCr 10 playback parallel rendering of A/B sequences.


Fix for initial preview/recording of 2x2x1080p (dual quad).  After switching to/from the ClearView Output record tab and then selecting the broadcast record tab and input modules 1 & 2 and then previewing would show the quadrants to be out of sync.  This problem would go away after stopping preview and restarting preview.






January 27 2014:


Fixed problem created when switching between YCbCr 8 and 10 bit image formats when using 2x2 dual quad video formats. Also fixed a similar issue when switching between regular 1080p formats and the 2x2 dual quad formats.  This could cause erroneous warning messages when assigning a sequence to a viewport stating the video or image format is different than the current format and needs to be changed. It also could cause problems with recording.


Fixed a crash when previewing 2x2 video formats.





January 21 2014:


Fix for recording using 2 quad boards on the single and dual players.  Made UI taller to accommodate the 4 inputs in the record tab.


Recording using 2 quad boards now sets the board video format to match the input signal format (SDI in 1 on each board)





January 15 2014:


Fixed problem importing 4096 x 2160 RGB10 DPX file - was reading as RGB10 and converting to v210 and then to 2vuy.  Now we force ARGB read and convert to 2vuy.


IPRecord input now works with the 0.7.9.X IPRecord versions.





December 29 2013:


Added new project to support AJA 11.2 drivers and SDK.  This is necessary to get the 4x1080p 29.97 and 30 fps.


Fixed a crash caused by starting ClearView with an incompatible analog output format or external sync format causing a warning dialog to appear which in turn was causing the applicaiton to not initialize properly.


4x video formats are now only enabled for systems with 2 3G quad boards.






December 9 2013:


Fix for crash when switching to Broadcast Modules 1 and 2 after running a 4K sequence on a single output module.  Reallocating format dependent memory on output module changes fixes this crash.





December 3 2013:


Fix for importing first two audio channels from a quicktime .mov file.  This is related to the change made in the previous update.


Changed warning dialog when video output format is not compatible with the external sync.  Also removed redundant error dialog.


Fix for DMOS log min max and avg values sometimes showing SSIM values instead of DMOS values.





Nov 26 2013:


Fix for importing Quicktime .mov file with 6 mono audio channels.  Requires MediaRead version 4.2.168 or later.  This fixes the erroneous number of audio channels and also problems with the imported audio.


Note this version also requires IPRecord version 0.7.8.13 or later.

Fix for ClearView Player when using two quad boards.  The bug is actually for all ClearViews when zoom/pan are disabled (No Render Mode).  The problem was seen with bad video on the bottom quadrants of the output video.






Nov 21 2013:


Added back in the Output Device combobox for the single and dual players.


Fixed problem with bad lower right quadrant on playback.  We now explicitly enable the second frame store on the second board when in dual quad mode.


Fix for importing .mov files with 6 mono audio channels - this loops thru audio channel pairs.


Now if Max Buffers is missing from the registry, we will still use 160 buffers when in dual quad mode instead of the default of 40 buffers.





Nov 18 2013:


Delayed setting Analog Output Format until after the app is fully initialized.  This guarantees the proper format is chosen to be compatible with the video output format.


Fix for doing In/Out mode when using a single 3G Quad board.  This requires recording on channel 1 and playing on channel 2.


Changed the jog buttons to keep increasing the increment amount up to 10,000 frames / 200 msec.


Added the ability to use reference signals with frame rates of half of the video output frame rates.  This allows a 29.97 reference for 1080p 59.94.





Nov 5 2013:


Added a new config option for Metric Window Exclude Vanc.  When checked this works like RTMonitor where Y == 0 means the first line of active video.  This affects all video metrics, alignment and pixVal.  When unchecked it works as before.  Also anytime a log created by RTMonitor is loaded in ClearView, we set a flag which also causes ClearView to work in this "RTMonitor" mode.  This flag gets cleared by Reset.





Oct 24 2013:


No Video HW Output Module Custom Video Format creation now supports floating point for refresh.  This is for compatibility with IPRecord when using the No Video Output module with 29.97, 59.94, etc. frame rates.






Oct 20 2013:


Fix for MAPI calls for IP Input and Protocol.  Values were not being set in the IPRecord dll.


Fix for returning FALSE after successful recording of IPRecord input.


Fix for using API to change video formats between 720p and 1080p when using IPRecord input.






Oct 16 2013:


Fixed problem where switching between Broadcast Output Modules 1 & 2 and a single Broadcast Output Module (1 or 2) was not setting the video output standard to match the current video format.


Added a new class for the Jog+ and Jog- controls to allow holding down the control with the right mouse button to cause the control to increment/decrement.  After a few seconds the increment value increases from +1/-1 to +10/-10.






Oct 9 2013:


New SSIM.dll fix for chroma scores being inconsistent and not correlating with luma scores.






Oct 2 2013:


Fixed crash initializing dual quad buffers to black when image format is YCbCr 10 bit.





Sept 25 2013:


Fixed bug with previous build where checking analog output format compatibility failure caused dual quad formats to not work.


Changed processing of api InOut command.  Now ClearView will allow the last frame to be less than the current first frame.  This relies on a new CVServer to enforce valid first and last frame values.


Switching between dual quad video formats causes the output to flash inappropriately.

Changes:

  Now we dont do the special work around for the Corvid22 and Corvid boards (disabling the frame stores and       waiting for 2 vert. interrupts before changing video formats)

  Now only set FB format, video format or VANC when changed.

  Now initialize quadrant buffers with black every time play or pause starts. This includes after changing video     formats.





Sept 24 2013:


New builds of AudMerge with latest IPP, etc.


Added threshold line to all metric graphs.


Changed IPRecord Config dialog to allow file input.


Added support for all image formats for IPRecord in ClearView (we previously only allowed YCbCr 8bpc).


Enable Analog Output combobox for 3G Quad boards to allow analog output of board one to drive sync on the second board.  Also connect FS1 to analog output on board one in router.  Added checking when changing analog format to make sure the new analog output format is compatible with the current video output format. If not, dont set hardware and reselect previous value.  Note: analog output does not work with some 1080p video output formats.







Sept 18 2013:


In config dialog added timer to check reference signals every 2 seconds.





Sept 6 2013:


Fixed disappearing input 2 signal status from broadcst record tab dialog after stopping recording when in dual quad mode.


Fix to allow recording on a 3G or 3G quad single board in/out mode when trying to record to channel (Framestore) 2.





August 30 2013:


Fixed problem with right edge of VideoClarity Logo when in YCbCr 10 bit mode.  The problem was in the conversion from v210 to RGB with the source image not being a multiple of 6 pixels in width which is required for v210.


Added support for Dual Quad Mode 2x2x1920x1080 video formats for the cvMsgAPi control.


Added support for the cvMsgApi ConfigInputIP, ConfigIPRecordScaling, ApplyIPRecordChanges.




August 21 2013:


Fixed sluggishness when jogging or shuttling when only a single clip is assigned.  Now we dont continue to read the same frame over and over after jogging.  Before we erroneously determined that the two inputs were not aligned, but this should not be the case when only one clip is assigned.





August 21 2013:


Playing when horizontal split is enabled looks bad and can crash when split point is adjusted.  Fixed by disabling multithreaded rendering when horizontal split is enabled.




August 19 2013:


Fixed intermittant crash assigning sequence to viewport.




August 16 2013:


Now when Broadcast Playback starts we check the External Reference (if enabled) and compare frame rate to the playback video format frame rate.  If not equal then warn user that we will disable the external sync to continue playing the current video format.


Added DMOS metric tab to RTM Player.  Previously loading .dmos logs caused RTM Player to crash.




August 7 2013:


Fixed problem where audio keeps repeating after reaching the end of a sequence when Play Once is selected.




July 24 2013:


Rebuilt VancUtil to use the latest Intel/IPP also removed MetricLib dependencies.


Fixed Handle leak when doing multithreaded renders (YCbCr 8 and 10 bit).


Fixed black previews for dual quad mode - no longer synchronous preview.




July 18 2013:


Fixed IPRecord jerky preview.


Changed version to 8.1.




July 16 2013:


Fixed frame counters were not working for Render Mode - problem caused by changing previews to synchronous.



July 15 2013:


Changed Preview for Broadcast Output (Render Mode) to be synchronous.  This fixes problems with tearing and Overlay disappearing.  This could possibly affect output performance since it requires and extra frame copy to preview buffer.  On my system this takes less than 1ms so I dont think it should have too big of an impact.



July 10 2013:


IPRecord update.


Fix for importing 24 bit audio - added Big Endian switch to config - default is little endian.


Changes for dual quad mode audio.


Fix for importing more than 2 audio channels using Drastic MediaRead.  NOTE: requires updating MediaRead to avoid crashing.




June 26 2013:


Modified PSNR chroma calculations - values used to be slightly too high.


Fixed Crash when running aFreq when one of the sequences clip align values changed.


Disabled VPID insertion.




June 11 2013:


For Single and Dual Player added Save Alignment Changes checkbox.




June 7 2013:


Added special registry setting to enable 16 channel audio mode.  Registry DWORD "Enable 16 Channel Audio Mode" set to 1 to enable. Note this works for Broadcast only.  Also only embedded audio.


Fixed problem in Dual Record - input 2 audio was coming from Audio subsystem 1 on single board systems.  Should come from subsystem 2 in this case.


Added new TTComboBox class to handle tool tips for items which exceed width of combobox.  This is currently only implemented for the Active Library combo.




June 4 2013:


Changed VPID code so that we dont supply SDK created VPID values and instead let the firmware do it. To do this

we clear the insert overwrite bit 27 in Registers 129 and 130 (if not 3Gb).




June 3 2013:


RGB 10 support for PSNR and DMOS (requires new SSIM.dll)


Fix for dropped frames when changing from pause to play.




May 27 2013:


Fix for single player - IPRecord Tab


Field Mode fix - side by side modes
