  • converting animiation to mimic stop motion

    Posted by James Bowers on June 14, 2008 at 1:16 am

    Ok, here is a tough one..I’m currently doing a project where a element was filmed in a stopmotion format. In other words when I bring the element into AE, the frames are set up in a way where the animation are in twos. First two static then two animated then one static again. So, I need to bring in a the non-stopmotion animated background to mimic the stop-motion element. But instead of manually doing it, I was wondering if there is a way, through expression, to achieve the same effect. So confused……

    For the background layer you can use Time Remap with hold keyframes, or you could try keyframing the Posterize Time effect.

    good advice, but is there a way to do it through expressions?

    I’m not an expressions guy; you might want to try that forum.
    But if there are any inconsistencies in the frame rate rate of the stop motion footage I don’t think an expression would be helpful.
    Your stop motion layer has a consistent frame rate as footage, even if the internal content was shot at a variable rate. AE has no way of seeing or interpreting the shooting rate, and so wouldn’t be able to access that parameter in an expression – if I understand your situation correctly.
    I think you have to do it manually.

    yes, that’s what I thought, hoping to get away of the manual thing in case more footage comes in. Thanks again for your advice, looks like ot for me on this one.

    Have you tried it without a perfect frame by frame match? I would think as long as the background moves at a similar but not exact frame rate it could still have a convincing look. Why not try some various rates with Posterize Time and see if any work out.
