Audio Problem

I have been using Adobe Premier Elements 14 for years. I record video using OBS studio in H.264 .mp4 format. I have not had any issues with this.

I just purchased Adobe Premier Elements 2021. When I load a video in this format initially I can preview it. As soon as I make any edit (usually I trim off the beginning where I am setting things up), when I preview (after doing render or not) it junps back and forth several times then starts playing, but the audio begins at the beginning of the file (not where I trimmed it) but the video starts at the right point. This happens every time I edit a track making it impossible to edit videos with this tool.

I tried an experiment and edited a short video this way and rendered it. It rendered the audio from the beginning of the original file but the video form the point I cut at.

I have tried the various steps, rebooted, ran adobe by itself with nothing else running. Same thing happens every time.

I opened a video in 14 and trimmed it then rendered it out. I opened the rendered video in 2021. Needless to say this is very annoying to purchase a new product like this and have such a bad fail.

Any idea what the issue may be? I can still use 14 so I can still edit videos.

Could you please post screenshot of the timeline where you are facing the issue -

Sure, it is kind of a dynamic thing, I am not sure a screenshot will show anything. I can do a short video capture if videos can be uploaded here. So I uploaded s short video demonstration of what is happening to YouTube and linked it here.

Oh and hitting render first does the same thing, no change.

No telling what specs OBS is using to create those files.

Open your MP4 in the free download MediaInfo. In MediaInfo, set View to Text and then copy the text from this report and paste it to this forum. With these detailed specs we may better be able to advise you how to proceed.

Here is the text from MediaInfo from an MP4 recorded with OBS that causes this behavior. I have tried rendering with 14 to a different format and it didn't have this issue.
