  • Converting 25 fps animation to play as if on twos, in a 25 fps composition.

    Hello,

    I’ve always wondered if I was missing a really easy way to do this –

    Imagine you have a bouncing ball animated in after effects, the frame rate is 25fps, and you have everything working really nice and smoothly with nice ease ins and outs etc.

    Then say you wanted it give it the more ‘hand made’ feel, perhaps its looking too smooth and digital on ones and making it look as if its on twos gives it a little more charm.

    You could drop that compositions frame rate to be lower, at 12fps – which works, and looks nice. But then if you want to drop this animation into another another composition which has to be at 25fps as its a video shot at that frame rate, then of course you newly made 12fps animation is going to play at 25fps again – making it super smooth, which we dont want..

    I know you could just render out the 12fps animation as a mov or mp4, and bring that into the 25fps composition and it would work ok – but I was wondering if there was an effect/plugin that could make a comp look as if it was animated on twos?

    Many thanks!

    In your lower-frame-rate comp, open the Composition Settings (Ctrl+K on PC, Cmd+K on Mac), click Advanced, then check the “Preserve frame rate when nested or in render queue” box.
