Control keyframes with marker
Hello,
I have some keyframe at the end of a comp layer which I will extending very often so I want something which can help move the keyframes around with MARKER so whenever I extend the comp layer to say 20 minutes, I can move the MARKER way to the 19th minute or something.
Any help or suggestion please?

There might be easier/better ways to approach this. Can you share a screenshot or an AEP with the keyframes you’re trying to automate so we can get a better sense of what exactly needs to happen?

Here’s a screenshot please….

If you were to precompose that, you could use a protected region to keep your animation together at the end of the clip so you’d only have to drag the end of the comp out.
When you have a protected region on one comp that’s nested into another, dragging the handles at the beginning or end of the layer does an automatic time stretch instead of a trim — but any protected regions are preserved.

Failing that, applying this expression to every keyframed property should have them start their animations at the time of the first marker on the layer, then run straight through:
try {
if (time >= thisLayer.marker.key(1).time) {
thisProperty.valueAtTime(thisProperty.key(1).time + time - thisLayer.marker.key(1).time);
} else {
valueAtTime(thisProperty.key(1).time);
}
} catch (err) {
value;
}
