Hi folks
An embarrisingly simple one that I'm struggling to find an answer to online.... I want to scale a layer over time, so if I change the length of the layer I don't need to keep moving keyframes. I know for Rotate it's just "time*2", but using this on Scale I get an error "expression result must be of dimension 2". Clearly this is because there is X and Y. Can you tell me how to do this please?
Many thanks in advance!
Do you want it to scale between the in point and the out point of a layer?
Do you want to constantly increase the scale over time?
The time value is in seconds so if you just wanted the layer to increase 5% in scale every second the expression would look like this:
t = time - thisLayer.inPoint;
v = t * 5;
[value[0] + v, value[1] + v]
If you want the layer to expand by 50% between the in point and the out point the expression would look like this:
t = time;
tMin = thisLayer.inPoint;
tMax = thisLayer.outPoint;
sclVal = linear(t, tMin, tMax, 0, 50);
[value[0] + sclVal, value[1] + sclVal]
