P: Glitchy Video in Timeline

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.

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!

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."

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.

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.

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

 

I was trying to quote @MartynMoore10649531 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."

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.

Exports using hardware encoding are very slow, and cause this glitch throughout the video. Happened since updating to Sequoia. Have just installed latest version of premiere and issue is still happening.

Hi @jakew39230329 - In your export settings can you try  switching to 2-pass VBR, or CBR resolves the issue.  If you turn off hardware acceleration do you still receive the glitches?  Can you post a screenshot of your media file properties.

Hi there.

 

Back in June I posted about a bizarre glitch that appears in the program monitor and also output files. The problem prevails and seems to be happening mostly with .MXF files. Here's my original post with a clip: https://community.adobe.com/t5/premiere-pro-discussions/glitch-after-cut-between-clips/m-p/14719592#M512023

 

I have just set up a new project and imported footage using the prescribed Media Browser method. Now I have pulled clips down to a timeline, I'm seeing this:

 

It always seems to be .MXF files. Could the two problems be related?

 

System spec: Premiere Pro version 24.6.1 (Build 2). Windows 10 Pro. Intel i9-7900X CPU @3.30GHz, 64GB RAM, GeForce GTX 1080 Ti, NVIDIA Studio Driver 561.09.

 

Ideas and suggestions are most welcome.

 

Martyn

Hello, I have struggled with the artifacts and glitches so long, as you can read in this thread. And finally the posts about disabling the hardware decoding helped me. So far I haven't noticed any glitch. Thank you!

But I don't uderstand why this feature is causing problems.
