  • lowering a framerate in a precomp…

    Posted by Nico Jones on June 8, 2006 at 6:50 pm

    hello everybody,

    I’m doing the old ‘getting posters on a wall to come to life’ effect. I have my subject precomped and then put on top of the poster shot.

    Basically, I want to lower the frame rate of the subjecton the poster to 16 FPS, giving them a jerky kinda look. When I bring down the FPS of the subject composition in the composition settings, the master composition overrides it and puts it back to 25 fps.

    I rendered out the subject at 16 FPS then brought it back in but that caused strange issues. Also; i don’t have time to render out and import a load of stuff…

    So, does anyone know of a way to bring down the frame rate of a precomped layer in AE? Or achieve a similar effect?

    thanks in advance…

    Nico

    Can’t you time stretch the precomp….

    Indeed, but I don’t want a slo-motion effect. I want the same speed, but lower framerate. Like when you lower the framerate of a quicktime for display on the web: same length but jerkier movement and lower framerate.

    like this, in fact:

    A thought… .
    – why not dupliate the layer then time strech one and leave the other normal.. then cut the one that is slow mow into tiny peices and hand build a slowmo track … or even through in some freze frames
    it’ll look all choopy and you will be in complete control…. ( I don’t know; I had three beers at luch …pay me no mind))

    Excellent idea sir! Sadly I don’t quite have time for anything like that at the moment…there has to be a simpler way??

    Well there we have it! I’ve been using AE for about 3 years now and I still don’t know what half of those effects do. One of the perils of being self taught and having no time to read manuals I guess. Actually what am I talking about, it’s just abject laziness…

    thanks steve

    In your Precomp Open Comp Settings select the “Advanced” tab check the preserve frame rate when nested or render queue.
    I think that is what you looking for.

    I was wondering when maintain frame rate in nested comps would be mentioned. That’s the easiest solution.
