Playback and export showing frozen, glitched frames

[quackquackq]

When I playback my video edit, it (pic 1) shows frozen frames and premiere pro will export the same fuzz into a video (export settings in pic 2). The audio is still continuous but the video freezes for a second and shows glitches then clears itself after a second or two. This happens in some parts of the video, but the majority of the video is fine. 

I made the editing timebase to 60fps from 23.976 fps (original source), but when I started a new project and loaded the source video with the original settings untouched, this fuzz thing still shows up at random points (sequence settings- pic 3). And even if I don't add any edits (I basically only use text and Motion- Position and Scale), the freezing still occurs.

The source video (MP4) plays fine outside of Premiere pro and has no glitches. Premiere pro itself is not laggy; it runs smoothly at full resolution playback and the same problem occurs at 1/4.

I've tried rendering it, restarting the program, reinstalling adobe, deleting media file caches, and restarting my computer, etc. but I can't figure it out.

Is there anything I can do and is there a reason why it's like this? Maybe it's my computer or adobe itself? Or something I did to the clips?

Thanks 🙂

To me it looks like a decoding issue, try to turn off hw-acceleration in preferences

@quackquackq  try this. 

I have something similar.

When i export a 25fps video, then it became streched and like "an interlaced" video(linear picture issue). When i turn the hw-acceleration off, and export the video, then it has no problems.

The funny thing is: When i turn the hw-a on and export another video with 60fps, then its export without issues.

wow thats interesting that it doesn't need to be turned on for the 60fps one hahah ill have to look into what hw-a does! thanks so much !

[quackquackq]

thank you! i didn't see this notifcation for some reason so i just ended up converting back to premiere pro 2019 and it solved the problem somehow? i will definitely try this out and look into this hw-acceleration!

Meanwhile the problem is gone in Premiere Pro. I have no export issues.

It does sound like it might be related to this setting in the preferences. This would not be there in 2019, which is why it might work for you.

If you try 2020 again (in version 14.2 or above, where hardware accelerated encoding[14.2]/decoding[14.5] was introduced) you probably want to try updating your GPU drivers. The issue would be related to that.

[quackquackq]

ohh that makes a lot of sense! thank you so much! when i go back to the 2020 version, ill for sure check this out and update my drivers 🙂

Just getting this issue now with some of my DJI Mavic 3 footage. Those specific frames would not play post render with GPU acceleration metal on. Turned it to software only and it was fine. Any one had this happen again?

Premiere Pro has sometimes problem decoding compressed files. The solution is often (always) to download Shutter Encoder encoding|converting video FREE PC|Mac  and then use the Rewrap function to rewrap the clip. Use the new rewrapped clip as your source file.

Rewrapping a file will not re-encode your file and it is lightning fast to do. Try it and report back if it works, or not work.
