How long is the sequence?
I would think you have to animate the mask frame by frame to match the footage. If the scenen aint way too long, when you got hold of it, it actually goes kinda quick. Put the mask on a solid and use that as an trackmat, gives you a bit more flexibility later on.

Or you could try to use Mocha, but i’ve haven’t use that much so I can’t tell you about it.

Thanks a lot Dan, that will work!

Thanks for all the answers!

The reason for me not to use keyframes is that I’m creating a project for someone else to work in, and that person is not deeply into AE. Therefore, I need to set up a null with all the controls so the person easily can adjust things with the slider tool.

Sure Target 2 is great, and I used it many times, but the pauses on the positions needs to be easily adjusted without going into the timeline and layers.

holdTime = effect("Slider Control")("Slider");
k1 = 2; // 1st hold keyframe
k2 = 3; // 2nd hold keyframe
p = transform.position;
t1 = p.key(k1).time;
t2 = t1 + holdTime;
if (time < t1)
t = time
else if (time < t2)
t = linear(time,t1,t2,t1,p.key(k2).time)
else
t = p.key(k2).time + (time - t2);
valueAtTime(t)

Hijacking this thread a litte, but this was exactly what I was after. I tried to add more keyframes to hold, up to 10. I started out with adding to the:

k1 = 2; // 1st hold keyframe
k2 = 3; // 2nd hold keyframe

and created:

k3 = 4; // 3rd hold keyframe

and so on, up to k10. Then I added:

t3 = t2 + holdTime;
t4 = t3 + holdTime;

Guess I’m doing fine so far, but here my little skills ended. How do I keep on adding to this expression? This part really messed it up for me:

if (time < t1)
t = time
else if (time < t2)
t = linear(time,t1,t2,t1,p.key(k2).time)
else
t = p.key(k2).time + (time - t2);

Dont know where to go from here though…

Thanks Brian, you can’t imagine how many times I accidently double-clicked and this happend to me! Now I know!
