MS Teams recording with 8fps - audio playback in VRD 6 build 827 problematic


New member

I need to edit and cut a video recorded with MS Teams today.

Indeed everything worked fine in cutting out parts and store the new video with fast-frame-copy as mp4.
Nevertheless, when I played back the video in VRD the audio comes only in parts with pauses in between.
Is there an option to configure this or is this a "bug".

Parameters of the input has been:

Any feedback is welcome.

I suspect that's actually a variable frame rate video. Try opening it in MediaInfo. Does it say it's variable frame rate with a large difference between the min and max?

Unfortunately VideoReDo does not support VFR video

Dear Dan,

I inspected the file with Mediainfo:



It seems to be a fixed framerate, but video 8fps and audio 15,625 fps.

So variable frame rate should not be the reason for the stuttering audio playback.

Ok well 8fps is the issue than. Our output chain only supports 15fps minimum.

You could try forcing a recode. Set the output profile to force recode and then set the framerate to 24. (use 24 because it's a multiple of 8)

There could still be an issue on the input side though. I'm not 100% sure if our decoder supports 8fps or not. You'll have to try and see. I've never actually seen a file that low.


Running the file through a quick stream fix solved it for me. The frame rate flag shows as constant after the QSF and it ran fine.
