Video and Audio out of sync

[devcoffee]

I've been doing with this problem for about 3 days now. I've seen all of the other posts and nothing seems to fix this. Literally the clip will be perfectly synced for the first 5 minutes and it will gradually get out of sync. Now the thing that makes no sense at all is that towards the end it begins to sync perfectly. I can't even begin to describe my frustration with this, it seems many other people have a similar problem.

Hi devcoffee,

Is this a screen/game capture file or a video clip from a mobile phone? If so, rip the file in Handbrake first. The variable frame rate you have recorded is the problem. Transcoding solves that issue.

Thanks,
Kevin

This is a screen capture. I'll give that a try right now, should I expect any drop in quality when I transcode it?

Exactly what is INSIDE the video you are editing?

Report back with the codec details of your file, use the programs below... A screen shot works well to SHOW people what you are doing - For Windows Internet Explorer press the PRINT SCREEN button on your keyboard, and then do CTRL-V to paste the screen print from the clipboard into a forum message

Does your video use a VARIABLE Frame Rate? See https://forums.adobe.com/thread/1110005

If yes, use https://handbrake.fr/ open source transcoder/converter to convert to Constant Frame Rate

Hi devcoffee,

Video quality after the transcode depends on the export settings. Please try transcoding & let us know the status of the issue.

Thanks,

Vidya

Software recorders are notoriously finicky.  I recommend using only hardware recorders that offer mezzanine codecs.

Great, I support it 👏

Can you please share your system info? Like OS and version, CPU, RAM, GPU vRAM, Pr version? Thanks. Also a screen grab of your issue will be helpful.

@devcoffee  I would definetly try what @Kevin-Monahan suggested.
Screen captures are naturally variable frame rate which will cause this issue
