Premiere Pro CC 2018: Audio/Video out of sync when browsing through timeline

[Rising Storm]

Hello everyone,

being new to Premiere I apologize if this is an easy fix or answered elsewhere, but more than an hours search still left me without a proper fix.

When I import a video to a project I can preview it without problems. Both Audio and Video are in sync. This gets messed up as soon as I try to go back/forth in the video but only due to certain procedures. Stopping the video or changing the current timestamp via the buttons in the program editor is fine. But dragging the current editing point on the timeline breaks it. The video will be out of sync, sometimes way too fast and even deleting and re-importing will not fix it anymore. If I happen to hover over the video after import and "browse" through the video timeline there, it will be out of sync before even played once.

Obviously I need to be able to go back and forth in order to edit properly. Does anyone have some advice here? It would be a lifesaver for me as currently I cannot edit anything at all.

What kind of media file? Does this happen with different video files from other sources?

[Rising Storm]

Currently I was trying MP4s but from two different sources - one being the PS4 Share function and then on to the PC via USB Stick. The second being an Elgato HD60S in between PS4 and PC while recording the stream with overlays through OBS. I checked it once more now and the Mp4 videos through PS4 share seem to remain fine even when f.x. previewing it immediately by hovering over the video after import. The OBS videos though do not work, so it seems to be an issue here, even if both are MP4.

I already deleted the media cache and media cache files as well as doing a full re-install of the cloud and premiere pro after deinstalling and using the adobe cleaner. Unfortunately the videos remain broken in the project as soon as I once browsed through them on their timeline. Within a new project they are fine again until again I either hover over them or use the proect timeline to drag the timestamp around.

Never used OBS but if those files are causing the issue - check the file settings there and perhaps try recording another format. Make it CBR rather than VBR.

[Rising Storm]

Asking about the file format already made me find the issue between MP4 from PS4 and via OBS. So I messed around a bit in the OBS settings, recorded something new, put it into the same "broken" project that already had OBS videos that caused issues and at first test, the new one did NOT have the same problems. I'm sure the rest can be fixed there as well, so at least I am not in the dark anymore - thank you very much for this!

Use the program Handbrake to change the video to a constant frame rate. the problem is that your video has a variable frame rate.. A lot of phones have this variable frame rate. You can get around this by using a good video camera app where you set a constant frame rate

There's no need to use Handbrake to convert files.  OBS Studio has all of the same "guts" to it as Handbrake does.  They're both built on top of the most excellent FFMPEG libraries and application.  The answer here is, ultimately to tell OBS Studio to create CFR files versus VFR files.
