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 always have the current public beta loaded, running naturally separate projects from my main Production using the current version.

     

    And the public beta always 'sees' my keyboard shorts and other preferences things from my standard Premiere user files.

    Everyone's mileage always varies ...

    No, not tried it yet Jamie, the Beta versions tend to not import settings like the keyboard set up and presets...or was that older versions? I'm concerned that the Beta version will mess things up…or am I being over Overcautious?

    Hi Jamie,

    I have had so much trouble with glitching on the timeline, I delete all render files, empty the caches, start a new project…import a project, change drives…done it all, but on export I still get the glitches, but its random, not at the same places. The only fix I have had that has worked was to export in ProRes 422 HQ HLG,

    Drop this back onto another timeline and then export it to my settings that used to work…HEVC (H.265) Main 10, 5.2, High, Rec.21 HLG, 203 (75% HLG, 58% PQ) when it exports, its perfect, a lot of fluffing around, but its the only way a can get an export without glitches, I hope you guys can fix this prono

    Hi @eegriff and Everyone -  We’ve made some updates in the beta version 25.4.0 build 16 that may address the issue. While testing is still ongoing, we appreciate the reports that helped guide our investigation. We’ll share more information as soon as we’re confident in a resolution. Thank you again for your patience and support.

      Idk if anyone else is having this problem, but I've tried everything from updating my drivers to the latest versions, to checking for updates. I'm up to date on everything. I do a lot of video work and for the past month I've been having this problem with premiere when I'm editing and playing back. One minute it's fine and the next time I use premiere these blocks pop up with glitchy playback. I've tried rendering my workspace and it's still there. I tried exporting it to see if it's just a small bug but it shows in the export. It doesn't make sense because the original clip doesn't show the artifacts. It only happens in premiere and after I export my videos. I've tried switching to an older version and it worked for a bit but it goes back, so I switch back to the recent version. I don't know what else to do so at this point I'm sure this is a bug on adobe's side unless there something I missed. This started once the latest update arrived.

        Please use the free MediaInfo and post a screenshot of the properties of your media in tree view:

        Many users are having issues with VFR. If the file is variable frame rate, use Handbrake to convert to constant frame rate before importing into Premiere Pro:

        Here is a tutorial:

        Shutter Encoder may also be used to convert to Constant Frame Rate:

        I'm having an issue with a glitch. It's only happening on one camera angle (canon r5c) and is consistent. It's does not happen of the orginal clip.

        Switched to DaVinci a few months ago mainly because of this (after 10+ years in premiere). Tried premiere today just to see if they fixed it. Don't know how they can charge 60 euros for this.

          My favorite part of this bug is that now the glitches are moving! The pixelation is now appearing in different parts of the clip where they did not appear before.

           

          This is so clearly an Adobe issue and still with no fix. This does not occur across any other programs or use cases. Frustrating.

           

          The workaround is to transcode to Prores, but that's not really appreciated file size-wise.
