P: Strange Pixelation Glitch when Exporting

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.

    @web Vaclav.Toman5E8C 

     

    Thanks Vaclav! Would it be possible for you to share with us a Premiere Pro project and media that display this issue? We have an FX6 (and most other Sony cameras) but, so far, we have not been able to replicate the issue you're seeing. 

     

    Regards,

      When I edit 4K footage in Premiere Pro, there is often a glitch. See the attachment. The glitch lasts for a few frames, sometimes before or after a cut. It doesn’t always happen—sometimes it does, sometimes it doesn’t. It tends to occur more often when the 4K footage is upscaled.

       

      The files are .mxf, filmed by an FX6.

       

      Sometimes everything goes smoothly and I only notice the glitch during export, but other times it’s already appearing while editing. The editing is done locally, with the footage stored on the local network. If the glitch appears in the project on one computer, it might not show up when opening the same project on another computer within the same network — though that’s not always the case either.

        Hi! We fixed the same glitch by disabling hardware decoding and encoding in the preferences section. Just 2 checkboxes and no more trouble.  

         

        Hope that helps others!

        Hello, please help. When editing material from the Sony FX6 camera firmware version 5.02, glitches appear in the export in the form of pixelated cubes. When I play the raw material MFX file in vlc, there are no errors. The glitches only occur in the Adobe Premier editing program, I attach screenshots

        March 14, 2025, and this error is still present in version 25.1.0 build 73.

        The material giving me trouble is from a Sony Z90. It's incredibly frustrating to have to sit down and troubleshoot these issues. I've tried all the suggested solutions here, and nothing works.

        I'm paying for a license, yet they can't fix a bug that was reported over three months ago. I don't care about AI improvements; I just want this thing to work for what it's supposed to do.

        I lost 14 hours of my life replacing glitches in a 90-minute concert because Premiere randomly showed glitches in both the timeline and the final render. The only way I managed to fix it was by cutting out the damaged parts when rendering the timeline sequence didn't work.

        Just like they force us to stay subscribed for a full year, they should also force their developers to make the software actually work.

        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.

          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.
