Playback out of sync after time

[xdjxklusivex]

Ive noticed with some files when you click play, the audio and video play in sync and then almost right away the video restarts but the audio does not.

That's even stranger.
Do these mp4 files play fine in Windows Movies and TV?

Yes, they also play fine in resolume when you first open resolume and load the files.

I have some free time this week so I am going to try to replicate the issue.

i have the same problem.
I created a new composition
I converted a video file with alley or with mpegstreamclip
uncompressed audio
the video is fine but the audio is not synchronized.
sometimes the sound is a little slower and ends after the video or sometimes the opposite happens.
I have increased the audio buffer,
I deleted and reinstalled
what can I do?

So which one?
Or does it happen with files converted form both?

Can you send us a screenshot of what the codec info shows in VLC for one of these files?

@xdjxklusivex
Were you able to recreate this again?

I don't know if this is the issue you are running into. But, the Adobe exporter is unable to render videos at 23.98, 29.97, or 59.94 fps. It will round down and your AV will go out of sync. Only render at 24, 30, 60 fps.

There is an exporter update that is supposed to fix this. Try updating to the latest version of Alley.
