P: Strange Pixelation Glitch when Exporting

Report · Dec 17, 2024

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.

Dear Adobe Premiere Pro Team,

I am writing to report an issue I've encountered while editing in Premiere Pro 2024 and 2025. When I open and edit a project in these versions, the video glitches during playback, with visual distortions and frame skipping. However, when I open the exact same project file in Premiere Pro 2023, the video plays back smoothly without any glitches or issues.

The glitching appears consistently at specific points in the video where no issues are present in the 2023 version. I have tried the same video files and edits in both 2024 and 2025, and the problem persists in both versions.

Could you please investigate this issue? I would appreciate any guidance or fixes regarding this playback glitch.

Thank you for your attention to this matter.

Best regards,

Adobe Premiere Pro version number: Version 25.00 (Build 61)

Operating system: Windows 11 Pro (23H2)

System Info:

CPU: 11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz
GPU (Intel-based Macs and PCs): Nvidia GeForce RTX 3070
GPU driver (PC): Version 566.14
RAM: 64GB
Hard Drive: 464 GB SSD, 1.81TB HDD

Video format: MXF

Workflow details: Sequence HD 1080p 25fps

Steps to reproduce:

Open the project in Premiere Pro 2024 or 2025.
Make trims or cuts in the video sequence.
Play back the edited clips.
Observe if glitches occur, typically at the beginning few frames of the trimmed or cut clips.
Compare with Premiere Pro 2023, where the same trims and edits do not result in glitches and play back smoothly.

Expected result: The video should play back smoothly without glitches or visual distortions, even after trimming or cutting clips.

Actual result: The video shows glitches and visual distortions specifically at the starting few frames of trimmed or cut clips during playback in Premiere Pro 2024 and 2025.

I work for TV and Premier has grown more and more unreliable in recent years.
The problem is that I have glitched Footage when I export Videos in Premier pro as mxf.
I keep having those issues over the last year. I really have no idea what to do anymore.

The glitches usually "stick" to a certain spot. But they look different and if relocate footage or sth the places change.

What I already did.
Update/Reinstall Premier and use the newest or older versions.
Update/Reinstall Drivers (clean install ofc)
Change Footage
Change Footage storage place, nvme hdd or external ssd
Change CPU and Motherboard....
Update/Reinstall Windows
With AVX 2 or without it
Change my PC. (I used 3 different systems. On apple it works. And on Davinci resolve it works always, also it's faster. Also I keep having issues with premier since forever but never with resolve which is free over years.... Just a sidenote.)
Disable GPU Rendering.
Clean Media chache.
rEsTaRt mY pC
Use Media encoder or Premier.
Disable Plugins, only have neatvideo. Also same issues when I didn't have neat video.
Rendered to different drives than the one the footage is on.
Changed name of the Footage.
Replaced the footage from the SD of the Camera.
Electricity is stable.
Cooling is for CPU is 28 degrees.
And I don't touch my PC during rendering.
22 Minutes 10Bit of 4k Footage in 10 Mins render.

I can't render it as 422 prores and then render it as mxf since the channels don't work for TV then.
I have the issues only on HVEC, h264 and mxf.

A friend uses the same cameras and never has issues.

I am really frustrated since I pay a lot for premier but it keeps bugging out. And I never had more than a month where it just worked.

My System has enough power.
96 Ram
4080.
i9-kf14900 (yes old one with the bug and new one with bios that fixxed it) also the older system had another cpu.

Everything else on the system is perfect.
Please help me.

Hi @resourceful_rainbow2877 & @nadineg73174863,

Thanks for submitting your bug report. I merged your posts since it looks like you are both having the same issue. Can you confirm which version of Premiere you are using and give more info about the footage type?

Sorry for the frustration and thanks for reaching out. Hopefully, we can help you soon.

Hello, I am on version 24.6.1 (Build 2), and the footage I'm working with is MP4s. I also export with Match Source High Bit Rate and H.264 so my export is also an MP4.

Report · Dec 19, 2024

Try to work with a sequence resolution that is equal to your original footage, and your export to match the sequence and see if it solves the situation. I had similar issues when using an UHD 3840x2160 timeline for a 4264x2408 ProResRaw resolution footages.

Here same glitch problem in rendered clips and on the timeline during playback. Editing with Sony MXF files.

Report · Dec 24, 2024

We have seen this too, with the HDCAM mxf format.

If you export in this format, you can fix export problems bij disable smart codec.

This setting enables very fast export of clips without any effects in the timeline. (Raw datacopy)

Clips have absoluty to be without any clitches and in the right format.

This is not always the case, sometimes there a copy errors, or clips are delivered with wrong export settings.

If you disable smart rendering codec, all edits are re-rendered to the correct MXF format.

Since I'm also encounting same issue, I upvoted this. I have seen this with two different computers (referencing one same network drive) with multiple projects. It's from about a week ago, but I didn't any updates or changes around system and Adobe apps.

Detail of the issue

Exported video contains pixelated glitch, at just after switching clips, in around 3-5 frames
Using H.264 "Match source - Adaptive high bitrate" or "Match source - High bitrate"

Computer A

Windows 11 Home Version 10.0.22631 Build 22631
AMD Ryzen 7 3700X 8-Core Processor, 3593 Mhz, 8 Core(s), 16 Logical Processor(s)
32GB RAM
AMD Ryzen RX 6600XT

Computer B

Windows 11 Pro Version 10.0.26100 Build 26100
Processor AMD Ryzen 7 5700X 8-Core Processor, 3401 Mhz, 8 Core(s), 16 Logical Processor(s)
32GB RAM
NVIDIA GeForce RTX 4060

App info

Adobe Premiere Pro 2024, first with 24.5.1 and tested with each versions between 24.6 and 24.3
What I tried: Cleaning media cache and previews, and clean install

Source video

Multiple clips captured with SONY Z-90
File type: MXF OP1a, AVC Long GOP High 4:2:2 10-bit
1920x1080 or 3840x2160, 29.97f/s

Other thing I noticed

Only few (not all) clips seem to have the issue.
There are the issues exporting whole sequence (around 60-90mins) , but not with exporting only 1 mins around same point.
No issues with exporting with macOS from same disk and projects.

I'm sorry I can't provide any sample since I'm mainly working with client works.

Hi, we are having a very similar experiencie overall as most of these users (specially as @nandenjin), as we also use a Sony Z90. I'll be adding a .XML file from one of the files that got those glitches, as we also have to work with client's content and unable to share none of it:

I'll be sharing some tips to overcome this situation for other users who find this:

- When you got your corrupted clips detected and selected, transcode them with Shutter Encoder (recommended), Handbrake or similar to any compression you desire (I used Apple ProRes just in case). Then replace the file inside the timeline.

- It doesn't happen on any other cameras apart from this Z90 we own (not happening on GoPro footage for example)

- It may happen at the beginning of clip cuts, or even in the middle of a video suddenly. It also has a bitter taste for faces.

- We also found out version 24.4.1 is the one that has a fair balance of features without the glitching issue.

Hope we could help anyone and the Adobe Team notifies us when this 2025 version gets usable for us, as of this moment we are avoiding it despite the features.

I also want to add to this experience. The issues I am experiencing are specifically with .MXF source files from my sony FS7. The glithes seem to appear on from the 2025 release onward, I am currently on 2025.1.0. CC2024 did not have these issues. The glitches appear throughout the editing at random locations, but the glitches are not consistent throughout the editing timeline. Spooling through the timeline at the same location will replay the glitch (from frame memory?), but when jumping through the timeline (or sometimes minimizing/maximizing adobe) will resolve the glitch. It might appear in a different spot next.

The glitches also appear in the Media Encoder exports but they have a different behavior:
1) They ARE reproducable at the same locations, rendering the entire timeline or only a problematic spot through in/out point
2) They appear on CUTS only
3) I have found no export settings (tried all of them which I know off) which changes the behavior.
4) The glitch happens also with different codecs (tried a bunch like prores, H264/HEVC, MXF, uncompressed AVI, etc)
5) The glitch appears in the export preview (within PP, not media encoder) window as well, telling that this glitch is very likely a decoding error
6) Shifting the cut one frame forwards completely fixes the glitch in my example. Is the cut maybe precisely on a keyframe in the sourcefile?)

7) Shifting the cut back to the original location re-introduces the glitch.

Attached is a screenrecording from me scrubbing at the location where a glitch appears while editing. Note that first the frame is loaded from some kind of framememory / cache (where the glitch is persistent), but the frame updates later to the correct one.
https://mega.nz/file/SjQS3ZSa#pSzPVyBeR0jKlGsTetsy_9IN4tU9IVlJKWauIIrOBvg

And here is a piece of the export where the glitch appears on the cut, in a reproducable manner:
https://mega.nz/file/ryBAQZwb#CHG6pKfdijxJ2WHrWzQMzJCNzKxPea_wAMJ9N-izkXA

Lastly, I have created a testproject (including a sourcefile), from which I can reproduce the glitch. I am very curious if other people can reproduce it as well.
https://mega.nz/file/6rAT3JAS#G0NBBpdf2R43hj7tBQmrROEPWnC9jIDrXeY4SEBlAlc

I invested a few hours of my time into trying to reproduce and experiment with this glitchy behavior. It would be very kind of the Adobe team if they can bump this in priority and investigate this behavior. For now I will (like other people) be downgrading tot CC2024.

Report · Jan 09, 2025

For me downgrading tot 2024.3 eventually helped, but I also read about a fix for the 2025 version, and that is to disble hardware accelerated decocing in settings -> media. Found it on this reddit thread
Appearantly this is a bug already longer associated with Nvidea hardware accelerated decoding. So people opening my previous project might not be able to reproduce it, because your hardware is different.
