Bug Report Media Source video loop has obvious blank frames and/or stutter

[tmad40blue]

Hi all,

I'm attempting to get the Media Source scene feature to loop a 10-second .mov file that I exported from Adobe Premiere Pro CC. The video itself plays beautifully until it reaches the end...

...at which point there is a very noticeable issue: there is either a split second of completely black frames (probably 9 or 10 frames), OR the video stops for half a second before restarting at the beginning of the loop, OR both issues happen, OR neither issue happens. Both issues are inconsistent: sometimes only one happens, sometimes both happen at the same time, sometimes neither one happens.

This is obviously an issue, as I created the video to loop seamlessly, and it's very distracting to my viewers to see a visible freeze and/or blank frame cluster every 10 seconds.

I've tried with various other video files of different formats and the issues persist.

Is this a known issue with Media Source, or is there something I can do on my end to solve this?

Thank you!

Just giving this thread a little push - it's been a week with no responses.

Thanks!

Another push for this thread - almost a month with no response whatsoever. Not really sure how else to go about reporting an issue like this. Is the OBS team reachable through any other means?

Where's your OBS log?

Where's your OBS log?

Here's OBS' log, taken during playback of the video in question - the video showed blank frames and stuttered 2 out of 20 times that I allowed it to loop.

What other compression and container formats have you tried it with?

None so far. What did I do wrong? Would you have any recommendations for how to export out of Premiere in order to get the best performance once I load this into OBS?

 

[Harold]

My first suggestion is to export out of premiere in lossless and use handbrake to compress it.
The h264 encoder in premiere is known to be problematic at times and offers a worse quality per bitrate ratio.

This issue is still existent. A small hitch at the end of perfectly looping videos when it would restart it.

Still no reaction from the developers or workaround?

 

[Osiris]

Developer, singular.
Anyway that small hitch is probably due to the source starting the video again.

Just now having this issue when I didn't have it before, the only thing different is the OBS version when I updated it to 29.0.0 from 27.2.4. I can see a few black frames when it start the video again.
