Hi,

I am having a consistent bug in which optical flow on clips renders improperly on my M1 Max Macbook Pro. This occurs on both .mp4 and ProRes clips during timeline renders and exports. This bug appears to have been around for some time. Unless fixed, I cannot use my M1 machine on commercial projects.

M1 Max, 64GB memory

Version 22.0.0 (Build 169)

Thanks!

Hello @rlr29711 and community,

A product manager has marked this bug as fixed in Premiere Pro 22.3. Please update to 22.3 or later to be free of this issue.

Thanks to @rlr29711 and the others on this thread for providing the info needed to reproduce the issue for the product team, which has led to a fix.

Cheers,
Kevin

Hello,

This issue should be fixed in the latest beta of Premiere Pro and will be included in the next release version of Premiere Pro. Information about how to use Creative Cloud beta applications is here: https://helpx.adobe.com/x-productkb/global/creative-cloud-beta.html. The summary of that article is that:

1. Beta apps are available from the "Beta Apps" section of the Creative Cloud Desktop app.

2. Beta apps are designed to be installed alongside release apps - it's completely safe to have both installed. However...

3. Beta apps are unfinished and should not be relied upon for critical work.

Regards,

Fergus

Hi all,

I'm one of Premiere Pro's product managers and this issue definitely has our attention. It's a bug we can reproduce and it is one we have logged. I do not yet have an ETA for when it will be fixed but when I do, I will share it with you.

My apologies that this issue has gone unaddressed for so long.

Regards,

Fergus

Was this fixed? I'm getting weird artifacts in my exports as well.

Not yet! Mine is still doing it. You have to use Intel Prmeire and export directly from Premeire. If I use Media Encoder to queue it will still have curropt video. Despite using Intel Premiere 😞

I have experince doing software encoding only or 2nd pass encoding ; it doesn't work. It turns out all my atempts exporting with media encoder didn't work.

The only real solution for me was to boot Premier using Rosetta, but it turns out that even using rosetta I had other weird gltich (some of my 4k footages (R5 422 CLOG) used to pixelate SO THEN I descided to do a clean instal of my mac OS and réinstal Abobe cloud software without using my Timemachine back up from my previews i9 macbook pro 2020 = seems to fix all my issue with Optical Flow in rosetta mode so far ! and mith NeatVideo denoiser pluging as well.

It turns out that using my timemachine of an intel Mac on a sillicon Mac isn't a good way to start using a Mac M1

Has everyone tried switching from Hardware to Software encoding? Not saying this as a permanent fix, just to see if either mode provides a different experience or if they result in the same corruption.

Same issue here on a Mac Mini M1. I have to send projects to my iMac Pro for a final export.

Version 22.0

Thank you for calling attention to this bug, speed effects are a core tool in an editors arsenal.

This bug also appears when I batch render to Media Encoder, even if I'm running in Rosetta, meaning I cannot batch export. Another frustrating problem, as I often have numerous delivarables, cutdowns and spec requirements for distribution channels, slowing down my workflow quite a bit and impacting my ability to hit deadlines in a timely manner.

Same problem for me with the lasted Macbookpro M1 max.

I'm experiencing glitches on my exports on almost each clip I used optical flow.

A real bumer 😞

Hi,

Don't have an M1 but have had issues with Optical flow before.

A work around for me was to nest the clip(s) I was using Optical flow on. Using Optical flow inside of the nest not on the nest.

A shot in the dark, but doesn't hurt to try?

No I am a professional editor and understand the limitations of Optical Flow and its implementation, and how to get it to work properly. This is a rendering error with M1 Macs and Premiere.

Same here! Creates really jerky curropt video.

Premeire 22.1.2

Apple M1 Max

64 GB

It completely cancels out me using Premeire M chip version!
