  • how to use the in and out point of a layer to control time remapping?

    Posted by Gerard Bowden on January 31, 2014 at 7:21 pm

    I am controlling a simple animation with a slider control. To that slider i applied the expression posted below.

    I want to use a similar expression to control time remapping. Im trying to have it play the first 15 frames from the in point, pause there, then reverse back to 0 over the last 15 frames.

    INOUT = thisComp.frameDuration*15;
    IN = linear(time, inPoint, inPoint+INOUT, 0, 100);
    OUT = linear(time, outPoint-INOUT, outPoint, 100, 0);
    (IN*OUT)/10

    i think i’d try it like this:

    t = thisComp.frameDuration*15;
    if (time-inPoint <= t) time-inPoint;
    else if (time >= outPoint-t) outPoint-time;
    else t;
