Hi,
17,4,3 Build 10, DaVinciResolve Studio (DRS), Linux...
Sources from mobile phone, music from a wav file.
This audio/video sync problem looks like a DRS bug and not a video source file issue.
I have several videos together with a music from a different source.
Rendering output QuickTime with MPEG codec, MPEG4 Video type, however I tried several such as DNxHD codec, without success as I have delay everywhere and only DRS is able to play the rendered file correctly. I even attempted to render with "bypass re-encode when possible" option cleared (so I expected to re-encode everything).
Checked on the same linux and uploaded to youtube and watch on both linux and mobile phone. There the video is behind the audio about 1-1.1 sec.
First I thought I cannot check the exact delay as if I take the same rendered video (with audio slip) and try to play within DRS there is no such issue, everything is as per my plan.
Then I took the VLC player and tried to change the "audio track syncronization" paramter. If I change it with constant 1 sec (or maybe 1.1) then there is no slip in the audio.
I read somewhere the VBR could cause this issues. In that case the 1-1.1 sec delay would not help in the whole video just a part of that, however in my case 1-1.1 delay on audio solved the issue during my test. But I cannot ask everybody to follow this. I would expect to get the same result what I edited and checked several times and DRS is able to play.
Any idea? Are you sure the source file cause issue after the rendering playing everywhere but DRS?
