Question / Help Audio desync after uploading.

[xgermz]

Not sure what's happened, however ive been using multiplatform for some time, and yesterday I updated to the latest "studio" version.

Since upgrading, ive uploaded 3 times, and in all 3 cases the audio goes massively out of sync. Even though in the local recording the audio is still in sync. i.e. the local file the audio is perfectly fine.

Never had this issue before upgrading... any help would be appreciated. If you need anny information, please prod me and ill provide.

(this is one of the logs, not sure which one to upload since there are quite a few in there)

Ok so no help? This is fustrating as none of my settings have changed. The only thing which has changed is upgrading to studio.

Maybe i shall upgrade back to working version, i.e. Multiplatform.

Also, i did a lil test, a 5 min video dusnt have the desync issue, only longer videos, i.e. 1 hours plus.

I'm having this exact same problem. Didn't seem to be an issue before, but has been constant on longer videos lately. No idea what I can do to fix it beyond just splitting every video into something shorter. Any insight would be greatly appreciated.

For video, Constant Frame Rate is important to avoid audio desyncs. Might that be it?

Not sure I follow. My videos are 60fps. Do you mean constant (versus variable) bitrate? I didn't even notice this was a problem since videos on my end were fine, and clicking around within the first 40-50 minutes of a video on YouTube was fine. I sort of assumed that converting to a different format before upload would help, but absolutely nothing I've tried has resulted in any difference at all, including using YouTube's recommended specs. Yet all my local videos are fine, and I have no problems with any other videos I watch on YouTube (it's often suggested that people are having trouble with YouTube's video player, which is clearly not the case for me).

My only solution thus far has been to cut everything into awkward chunks under 50 minutes, before the desync gets too pronounced. Not really ideal as I'm not formatting this content specifically for the usual YouTube-style episodes.

EDIT - Here's my last logfile, in case anyone notices anything that might be causing it on the OBS end rather than specifically being YouTube's fault: https://gist.github.com/2732f8a4149dd8d24ee5afc9942cc0fc

No, frame rate. Just offering it as a possibility, as (to my limited knowledge) NVENC and QuickSync encoders don't currently offer constant frame rate encoding in OBS Studio whereas x264 does.

Thanks for the clarification. I really don't know a lot about this stuff. Trying to learn, but it's a bit like being thrown into the deep end of the pool.
