Two Questions – one easy, one perhaps impossible! A challenge!
Hi all,
Ok, first question – I’ve looked everywhere but the simple question is – how do I invert the value read by an expression e.g. – I want the audio keyframes I have generated to cause the opacity of a layer to be 0 when the keyframes are at max, and 100 when the keyframes are at 0 ?
Next question. is it possible to imitate the effect of scubbing backwards and forwards through a comp?
Thanks in advance

Fist question:
minAudio = 0;
maxAudio = 20;
minOpacity = 0;
maxOpacity = 100;
audioLevel = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);linear(audioLevel,minAudio,maxAudio,maxOpacity,minOpacity)
Second question:
Sure. Use time remapping (either keyframed or expression-driven).
