P: Glitchy Video in Timeline

[eegriff]

After I upgraded to 24.4 several days ago, I can no longer edit MXF video files. The video in the timeline is glitchy, with pixelated blocks displayed whenever something moves in the scene. The glitches are exported in the final render, so it’s not a temporary or display-only issue. (If I render the MXF to MP4 with HandBreak, there are no glitches in the output, so I think the MXF container is OK.) My camera is unchanged and I’ve used this workflow hundreds of times. I went back to an editing session from before the 24.5 upgrade and all is fine–no glitches. I cleared the cache, rebooted my Mac, checked the sequence settings, but nothing helps.

Hrgh, I'm having issues with this forum not quoting properly. Can that post above be deleted?

I was trying to quote @MartynMoore saying "Before version 25 I could put the playback head on a clip that showed the glitch and the glitch would stay there on the frozen frame indefinitely. Now with version 25 the glitch appears in the Program Monitor and when I pause playback it remains for about a second and then disappears. The paused frame cleans up and displays properly all by itself."

Me:

Yes! I had the exact same experience! Your story sounds very similar to mine. I think all our problem MXFs are from Sony FS7's. FWIW, I also tried the old "start a new Project and import the old Sequences and media into it" trick, and that never worked.

The only thing that DID work was using this trick to convert the Premiere 24 project file into a Premiere 23 project file, installing the older version of Premiere, and then opening it in that:

So it seems like it's a 24-and-up problem.

That fits with my experience, Edward. When I took the laptop on location with me I will have updated the OS and Premiere Pro to v24.3. I had long-running projects over the winter so my desktop probably remained on version 23 from around June 2023. When I transferred the project I was probably told that it had been created using a newer version of Premiere Pro and encouraged to update the desktop. Then the .MXF glitches started.

[MartynMoore]

I found two consecutive frames that showed glitches when I moved the playhead to them. Each glitch cleared after the playhead had been on it for about a second but always reappeared when I moved onto those frames using Step Forward and Step Back.

So I turned off hardware accelerated decoding and restarted Premiere Pro. Returning to these glitchy frames, the glitches have gone, so this workaround seems to have improved things for me.

[Edward3492930152k1]

I tried the same, turning off hardware accelerated decoding and restarting Premiere, and that seems to help in the Timeline. However, exports still include the glitches. Even when I set "Performance" under "Encoding Settings" to "Software" instead of "Hardware."

[MartynMoore]

Must be infuriating. I haven't exported today, so I might be in the same boat. Spent the afternoon sending clips to Jamie, together with screenshots and exported frames. Not editing again until Monday now. There are a few of us wrestling with this so I'm confident it will be resolved. I don't want to be converting all my files!

[Edward3492930152k1]

Copy that!

I'm having the same problem on multiple systems. Lost 10 days of editing so far. Exports all show the glitch also. Opening with Shift is only a temporary fix, a minute into the edit and it's glitching again.

I'm on the latest version of main and Beta versions, 25.0 and 25.1. 

Sony .mxf, 4K, 60fps and 30 fps. 

AMD Ryzen 9 5900X 12-Core

32GB High Speed RAM

Windows 10 Home & Windows 11 on 2nd PC

NVIDIA GeForce RTX 3060, 12GB, running Studio Driver 565.90

Sorry for slow reply. Yes ! I did clear cache. I even went to appdata to certificate everything was clear. However i didn't try yet the Studio Driver as you recomended. Still using the Version 24.3 and everything ok!

I am using 553.09-quadro-rtx-desktop-notebook-win10-win11-64bit-international-dch-whql. 

Today it was released the update 553.24-quadro-rtx-desktop-notebook-win10-win11-64bit-international-dch-whql.

I will try with both (Studio driver and update 553.24) and let you know if it fix the Glitch bug for premiere pro beta.

[davids77232656]

Clear cache and uninstall the version you have. Then try install premiere Version 24.3.

Everything went ok for me. At least till now...

I started having this issue yesterday, it's driving me crazy!

I updated to Premiere 25 about 5 days ago, but only noticed it happening yesterday. I usually work with proxies on a NAS, and I haven't seen it happening, but yesteday I was trying to finish a quick project without proxies on my local m.2 drive, it seemed fine while working, but when I exported there were a couple of clips with glitches and when I checked back on my program monitor, there were some glitches there now too, it's possible they only appeared after grading with Lumetri. It seemed like a rendering issue because when I pause on the frames that are glitching on the program monitor, after a few seconds it renders it completely and the frame goes back to normal. The glitch also disapperas if I hide the grading layer.

Today I tried a different project, also without proxies, on a usb-c ssd and the same issue happened.

I've tried cleaning the rendered files, cleaning the cache, I tried creating new sequences, I restarted premiere, and restarted the pc. I think the only difference I saw was when clearing rendered files, the glitch changed from happening in the same part of the frame to some other part of the frame.

I was desperate to deliver a video today, so I installed Premiere 24.6 again, but my latest working files were on PP25, so I used a downgrader to open it back on the 24.6 version, the problem continued on my program monitor, but the export came out clean, but it could have been just a coincidence as this particular project was mostly mp4 footage. I haven't had time to test my other project from yesterday yet.

It's happening on Sony MXF H.264/MPEG-4 AVC Long GOP High Profile 4:2:0 Unconstrained Coding

I've had mp4 H264 in my timeline as well, and that didn't seem to have any issues.

My PC setup:

AMD Ryzen 9 3900X 12-Core Processor

64GB RAM

NVIDIA GeForce RTX 4070

Windows 10 Pro N

[Neander_Rodrigues]

I have the same problem, but after some testing I noticed a pattern. All machines that had an Nvidia RTX 4070 had the same problem, in the same export location. I was able to export normally and without errors when rendering on a computer with an RTX 3060. I don't know if there is any correlation with the problem, but it was the way I found to get around the error. The same error occurred in 5 other MFX h264 projects from Sony fx6. I tested on 5 machines with RTX 4070 and they all had the same problem when rendering.

Example of the error:

[jamieclarke]

Hi @Neander_Rodrigues - Thank you for the information, can you let us know what driver you are using for the 4070?

[Neander_Rodrigues]

Hi @jamieclarke I am using nvidia studio 561.09 driver

I have an idea where the glitches might come from.
I have 25 installed. Newest version.
Started a new project. And imported MXF long footage.
When you import new footage in a project there is a line at the bottom. Maybe consolidating or something.
During this time I watched a YouTube video.
The YouTube video gave glitches at that time.
Maybe there where glitches made in the cache file for that video at that moment?

When I deleted the cache, the glitches where gone.

Just a quick thought. 
Maybe this helps.

SO PP25 is not free from glitches with MXF footage. But maybe that is because we do not let the graphics card work for premiere pro only...

BEst regards, Christiaan
