Bug - inverted frames, skipped frames, pixelated frames - when original video is perfect

[7thheavengtr]

There seems to be an issue with Premier that does weird things to the video, edited on a timeline.

The original video does not have the issue.  It is clean.  (see attached same frame of original in quicktime, and same frame on premier)
So it randomly does this.  Once it happens on the timeline, it stays there.  Even with render in to out.  Even after exporting in various codecs (pro res, mov, H264, etc..)
I see other are having this issue too.

How do I fix this, without having to edit this in another app?

I did try rebuilding the cache, and still not working correctly.

Try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).

Try updating the driver. That is almost always a GPU driver problem.

I am re-sizing video files, and they seem to be ok, until I start chopping them and editing them.  Then I start getting random pixelations. 

It happens in the timeline video.  Even after rendering, it's still there.  Only way to get rid of it is to re-do all the work.

Hi 7thheavengtr,

Sorry to hear about this. Could you please confirm the version of Premiere Pro, OS & the GPU driver version that you are using? Also, is this happening with any specific media or all of them? Let us know, we're here to help.

Thanks,

Sumeet

Raw Video - MPEG4 - one I'm editing and is dropping pixels 

Is there a way to rebuild it, without losing all my editing and links?

[Sumeet Kumar Choubey]

Thanks for confirming that. Generally, GPU drivers on macOS are integrated with OS updates. Have you checked if there are any updates available for your Mac? Also, what is the source of the media file (recorded on a camera or encoded from any other app)?

Mostly MPEG4 videos, converted in size.

Want me to upload the session and raw videos?

You can see it on your end 

[Sumeet Kumar Choubey]

Sure, please share a download link for the sample media with which you are experiencing this issue. We will have it checked.

Thanks,

Sumeet
