Hello! I've been working with Premiere Pro for the past few months without any issues. I've been recording gameplay/ cam footage in OBS as MKV files then converting them in VLC to H.264+MP3 (MP4) files for Premiere Pro. When I view the imported files in the source monitor in Premier pro they look and sound correct. In my clips there's often a few seconds between the clip starting and me talking. I place the clips on the timeline and use the razor tool to cut out the video/ audio where there is no talking. I do this for all clips (generally 5-6) and move them up on the sequence timeline to create part of the video. This has worked flawlessly in the past.
As of this week doing this method is getting me weird results. Now, when I play the sequence back with all of the clips in it after editing, I get very out of sync audio. All of the MP4 files I'm working with have the audio/ video linked and I make sure that nothing is visually out of sync on the sequence timeline. When I play the sequence some clips will have the audio start a second off from the video, despite the timeline showing that the audio should start as soon as the video does. There's also instances of the single audio source somehow playing over itself during playback - The audio from the audio track will stutter or repeat what was just said when this is not present in the original video/ audio. It feels like Premiere is letting me trim an 11 second clip down to 8 seconds while continuing to try and play all of the audio from the full 11 seconds in 8, with lags and stutters present if that makes sense. It sounds awful.
I get these same errors even if I try and create subclips in premiere first instead of putting the full clip on the timeline and using the razor tool to shorten. When marking the in/ out of the subclip in source monitor, the audio will get out of sync from the video before I even make the subclip. It's almost like premiere can see that I've shorted the clip on the sequence timeline but still wants to find a way to play the full audio despite it being cut/ marked out.
My computer specs are below, I have not had any performance issues with premiere in the past either. Any thoughts on what could fix this??
There are a few things we can try! First I'd try opening your main clip in the Source Monitor by double-clicking it in the Project panel. Then open the Effects Control panel and see if you get the option for Variable Frame Rate mode. If you see it, enable it!
If you don't see this option, I'd try using Handbrake.fr to transcode OBS clips before importing them into Premiere. Let us know if either of these help!
Hello! Thanks for the quick reply 🙂 I do have preserve audio sync enabled for all clips in the effects control panel, is that what you mean by enabling the option for variable frame rate mode?? All of the clips I've used for this and past videos have had variable frame rates.
I can try re-transcoding in handbrake but I also want to show something odd that I've found when looking at the timeline preview. In the ADS penal1 attachment I can see that the audio is apparently going to start playing with the beginning of the second clip on the timeline @ about 3 seconds in. In the ADS penal2 file, I zoomed in just a touch on the timeline but the audio for clip two changes to start at ~4.5 seconds in.Clip 2 has a short pause of no audio at the beginning that I had cut out of the audio/ video file in premiere via the razor tool, but the full audio seems to re-appear when I zoom on the timeline? When I play the video, there is a delay in the audio starting and the end of what I'm saying gets cut off as the clip finishes. It's almost like it's still trying to play the original audio despite being clipped.
