Expression to move clip on timeline

[Dan Ebberts]

Expressions can’t move a clip, but if you turn on time remapping for the clip, a time remapping expression can determine when it plays.

I thought that might be the case but figured I’d ask. I’ll look up time remapping.

[Dan Ebberts]

For example, this simple time remapping expression will hold a clip at frame 0 until the clip’s first marker is reached. The clip then plays from the marker onward.

t = 0;
if (marker.numKeys > 0){
  t = time - marker.key(1).time;
}

In case anyone else comes across this, here is the code I wrote to use a Marker to control the Time Remap. This marker is on the layer you want to adjust but you could also link this to any marker in a project.

var mark = thisLayer.marker.key(1).time; //Marker location
var begin = 0; //Start point of your clip
var dur = 1.2; //Clip duration in seconds

linear(time, mark, mark+dur, startTime, dur);
