    I can’t for the life solve the problem…

    Originally I thought it could be a slow hard drive. But after multiple renders and compressions, it does not change.

    Sorry, let me explain my problem. I recorded the video with a HD handy cam at 1080i at 25fps. I colour corrected in after effects and exported the video uncompressed so I can import it and edit it in Premiere Pro. Original format is .mts files.

    But the output video is all jumpy. Audio works fine. But the video jumps back and forth a few seconds. Argh!

    My system should be more than sufficient to handle the video (iMac 27″ i7 2.93 GHZ Quad Core 8GB RAM) And no “it’s cause it’s a Mac” jokes 😀

    Have you installed the After Effects CS5 (10.0.1) update? That update fixes a lot of problems.

    I’m using CS4 and have yet to move to CS5. My University and workplace does not use CS5 yet (work apparently plans it for next year though…) So at the moment I’ve stuck to CS4 at home until more places have adopted CS5…

    Thanks for that. In the end, that’s what I did. I’m also a massive fan of the Quicktime format and reconverted in the end. It was a just a pain since I had already originally done all the editing in AE and didn’t want to have to go through and transfer all my colour corrections. But I guess it can’t be helped. I was hoping I could find a solution that didn’t require reconversion.

    But thanks for explaining WHY. Now I can sound all cool and smart when someone else has this problem. The internet makes me look awesome.

    I had to get the job done by the end of today, but I guess I’m pulling an all nighter reconverting all the video and retouching again. Should have seen this coming.

    So, for all the other poor souls with jumpy, jittery, badly running, bad HD video. This is your answer. Get converting. Now.

    Thanks again Dave!

    PS. First time on this forum, but your photo… you seriously look like a white version of my Asian Grandad… Like, one for one resemblance…

    Pro tip: Rather than recreating all your color correction work, just replace the old .MTS files in your AE project with the new good ones.
    From the AE help file (found by searching for “replace”):

    To replace the source footage item for a layer with another footage item, without affecting changes made to the layer properties, select the layer and then Alt-drag (Windows) or Option-drag (Mac OS) the new footage item onto the layer in the Timeline panel.
    To replace all uses of selected footage items with another footage item, select footage items in the Project panel, and then Alt-drag (Windows) or Option-drag (Mac OS) the new footage item onto a selected footage item in the Project panel.

    Yeah! Though of that!

    I was nervous things might get out of whack if I do that. Being different formats and all. I’ll go ahead and do that then. Yay! … Still need to wait for a new conversion though 🙂 Don’t have like 24GB of RAM to power through for me 😀

    Thanks for giving me more opportunity to sleep! That tip was greatly appreciated.

    I mean, seriously, sleep is so underrated.
