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.

    I am a wedding videographer and I've noticed this glitching is now happening on long exports as well as even short exports.

     

    I use three cameras: Sony FX3, FX6, A7IV. The footage from FX3 and A7IV are XAVC-HS 10-bit S-log3.Cine MP4, the footage from FX6 is XAVC-L 8-bit  S-Log3.cine MXF. I generate quarter-size ProRes proxies for all clips prior to editing. 

     

    I utilize multi-cam sequences within my video sequences. 

     

    My computer specs:

     

    Windows 10 Pro

    Intel i9-9900k 3.6Ghz

    64gb Ram

    Nvidia RTX 3060 Ti 

    Premiere Pro 24.6.1 (Build 2)

    Media Encoder 24.6.1

    Footage is located on a Samsung 4TB 990 Pro M.2 SSD within Dropbox Desktop.

     

     

    The footage plays and appears fine (even without proxies enabled) in Premiere pro playback as well as outside Premiere Pro on the hard drive, but when I render (using CBR and VBR), occasionally the footage will contain crazy artifacts, mostly only on the FX6 MXF footage. See attached screenshot for example. This glitching occurs multiple times throughout certain areas of renders.

     

    I tried trashing preferences, cache, restarts, etc. The only solve was downgrading to 2023. Please fix this crazy bug or let me know of a solution.

     

    Thank you.

    @jamieclarke We already did, as stated was in my previous message. In the timeline you get glitches and artificats on specific clips. If you stay on the frame and keep it for 5 seconds the artifacts and glitches disappear. But then after a new scroll through the timeline you get new glitches. 

     

    It's always the same clips that get the glitches in the beta and previous releases.

    Hi @vic.msl - Can you go to settings under Media and uncheck the boxes "h.264/HEVC hardware accelerated decoding" and "H.264/HEVC hardware accelerated encoding" , Quit and Restart Premiere Pro and Please let us know if that helps your issue.

    Hi @jay from jam-AV - Can you elaborate on what you are experiencing?  Are you saying that you are still receiving frame recursion errors?  Can you post you Premiere Pro version and specs of files please.

    the MXF problem isn't solved using the Beta Version I installed today. Demaged frames are still there.
    When the project was created, I had no problem like this one. It happens since the last 2 or 3 updates.
    Please solve it fast. All my projects with MXF footage are unusable.

    Sorry for my bad english!

    Unfortunately, I have still the same problem (in new beta version too). I didn't notice any alerts about "Frame substitution..." during my few hours of work, that's true, but I still have a problem with pixalation. Both in editing (the screen is attached)

    and in exporting (demonstration here: https://drive.google.com/file/d/15UluqEDoFLNXVXbPpAkeF3brI6kYHgyW/view?usp=sharing)

    I don't know what I will do. I have i big project to cut now but it's unthinkable in this sutuation.
