You record a meeting, so the content can be published internally for later use. After the recording has been completed, a pop-up dialog Box appears from Skype for Business Recording Manager. You chose appropriate options and then select Publish.

When reviewing the published video, you realize that the video quality is sub-par or deteriorated, when compared to the video that participants in the meeting were observing. If your meeting allows for HDVideo, we will allow for video resolution to be upto 720p and upto 30 fps. The content by itself is saved in the same configuration on the local.

The Skype for Business Recording Manager, in-order to optimize the recording ( file size generated) will encode the video from 30 fps to 15 fps, which can cause the rendered video to be choppy/ flaky / in-consistent, depending on the amount of motion in the source video. This was deliberate design, to allow for smaller files that can be saved and published for later use.



Resolution:

Skype for Business Recording Manager has an option to publish the video at 30 fps. This can be done by modifying the registry key called VideoFrameRate from Decimal 0 to Decimal 30 at the following location(s):



For Skype for Business 2016 clients:

\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync\Recording



For Lync 2013 / Skype for Business 2015 clients

\HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Lync\Recording



While this is a great action to perform before the meeting has occurred, the same registry key can also be used AFTER the meeting has been published as well. If a registry key is modified and the video is re-published ( on the same machine, where the original meeting recording occurred and where the video was published), the newly published video will be at 30 fps.
