  • How to limit a expression’s values within certain limits

    Posted by Tamás Krizsán on July 29, 2013 at 7:37 pm

    Hi!

    im looking for a solution for the following issue.

    im trying to use a audio amplitued based scale property expression for a video to achive a “zoom in” visual effect synched with the beat of the music.

    In default the expression is outputting values below 100% (which is shrinking the video from its original size, and making black bars around it)

    Is there any method to make a expression which is outputting values above 100% Scale value?

    Here is the “beatmatch” expression which i working so far.

    any help greatly appreciated.

    thx

    Tom

    temp = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");

    temp = (your expression);
    amplification = 1;
    100 + amplification * temp;
