Question

After Effects keeps glitching back to a certain frame throughout

Hi everyone, I'm currently trying to render this video edit I have made, but a frame from the edit keeps glitching in between clips throughout the edit. When I put I black solid underneath all my clips, the frame goes away and instead it has the same glitch but black. This glitch doesn't show up in After Effects itself, only after rendering and while its rendering I can see it rendering the glitch frame.

Any help would be greatly appreciated,

Shannon.

    Whenever I try to render a project file on half, some frames of the video get glitchy and look like the screen of a broke phone... do you have any tips to give me?

    The imported clip is the culprit. Check frame rate and codec and make sure it matches your comps. If it doesn't plz make changes so that it does

      I'm litteraly using jpeg image sequences, the (interpretted) framerates all match, purged memory, restart, glitch won't go away.

      Hi, Try Couple of things

      1. edit > purge > al memory & disk cache...

      2. check frame rate of all your clips and composition make sure they match use full frame rate numbers if possible

      3. if you have roto tool or something similar in a pre-comp and on that that layer your doing time stretch or time warp operation it tends to glitch avoid pre comping or render that scene seperatly

      good luck!

          the difference between frame rate specially with mp4 video can make glitch most of the time, to fix this simply transcode you mp4 video to so better codec like ProRez using media encoder than brought the video to AE

          Is this "glitchy" frame a video you brought into the timeline or an asset created in AE? If it's an asset from within AE eg a solid layer, shape layer etc are there any effects placed on this layer? Generally these kind of glitches occur when u bring in a video file or even a still image that was not properly encoded and AE finds difficult to render as it doesn't match frame rates or the codec you are outputting to. Could you kindly explain what the AE project is so that I can try to figure out a solution.

          So the glitch is a clip that i’ve brought into ae. With this project I had one mp4 video of clips which I split and placed along to go with the beat of an audio. I have adjustment layers above/in between most of these clips and the adjustment layers have transform on them. The glitched frame comes from towards the start of the video but not the very first frame. The glitch seems to occur when there is a split between clips, they line up perfectly and should play with no gap, but the glitch occurs here.

          Hopefully this is enough information

          If the glitches are indeed happening right at your layer splits, it does make me wonder if something about the frame rate is at play, or if some of the effects you're using (is it only Transform?) might be interacting in an unexpected way.

          If the clip in question isn't prohibitively large, I'd be happy to check out your project and see if I get the same behavior.

          Double-check to make sure your video card drivers are up to date - that can be the culprit of a lot of weird little issues.

          Are you rendering directly out of AE, or using Media Encoder? To what format?
