P: Strange Pixelation Glitch when Exporting

[resourceful_rainbow2877]

Hi all, I'm a very amateur video editor but I edit podcasts part-time. I've recently been having really weird graphical glitches when I export my files and I have no idea why or what to do. I've been searching the web for answers and figured I'd ask here.

For context, I use the latest version of Premiere Pro and I'm on Windows 11. I export using the default settings so I think it's H.264 and Match Source High Bit Rate. If I need to provide any system specs please ask and I will find it. I've exported twice already and both times I've had this glitch, but in different places. It happens briefly, but it's still very noticeable so any help would be much appreciated, thank you.

Just for the people visiting this thread, there is another Reddit thread with more information why this might be happening:
https://www.reddit.com/r/premiere/comments/1ebc38s/mxf_file_issues_in_the_latest_premiere_pro_fix/?r...

Most notable comments:
"I have experienced these issues and it seems to be related to the addition of hardware decoding support for h.264 in MXF wrappers such as Sony XAVC-L and Canon XF-AVC, specifically when paired with Nvidia GPUs for decoding.

Disabling hardware decoding in preference > media resolved the issue on all affected machines I tried it on in 24.5."

"for me, it's 10bit LongGOP specifically. Intra-frame and 8-bit work just fine. which is really strange considering all things."

"

We had the exact same problem.

Sony FX6, MXF wrapper, Adobe Premiere Pro 2024.6 (2024.9 is prone to this error too). Windows 10 22H2. Nvidia studio drivers 572..575. Different machines - with RTX 3070, GTX 1660, Quadro P4000, Quadro M4000. The only stable solution is to downgrade Premiere Pro to 24.3, the latest version before hardware-accelerated MXF decoding.

I've dealt with this in previous versions of premiere and figured out how to fix it before, but now it's happening again and the old fixes don't appear to be solving it.

Attached are two versions of the same image.   The better looking one is how a jpeg that I'm using in my sequence appears in my browser window during playback.  The degraded image is what the same image looks like upon export.

In the past, I've worked around this by either rendering and "using previews" in the "general" tab on exports, or futzed with th the Variable Bit Rate, 1pass v 2pass settings.  But I've done a battery of tests on this thing, now and the bitrate changes nothing (even CBR, still the same issue), and neither does using previews.  routing through Media Encoder has not helped either.

any ideas?

Hi all,

Apologies for the inconvenience caused by the glitches with MXF files.

We’ve implemented a fix for this issue in the latest beta versions of Premiere (build 25.4.16 and later), AME, and AE.  This fix is expected to be included in the next official update of Premiere Pro, AME, and AE.
Thank you all for your support and collaboration in investigating this issue.

While we don’t recommend using beta versions for production work, the beta installs separately from the release versions and can be used if you'd like to test the fix. Please let us know how things look on your end after testing the beta.

We sincerely appreciate your patience and continued support.

Thanks,
Mayjain
