Great Tut--Thanks!
But I still can't entirely grasp the relationship between the anchor point and the position. What did that do for the footage? Would someone explain further?

Great bit of thinking there Pete.
The work around for improving the playback is a big help.
I'm wondering if its possible to take the repositioning idea and use tracking data instead. Track the van and then use that for position data creating a temporary relatively still object. Then roto the edges as they change and reapply the tracking data to get the mask to move as you did. I'll see if I can work that out.
Hopefully these work arounds will all be old school when Adobe gets to adding roto specific tools to AE.

HI everyone, thanks for your responses. I'm glad to hear you all found it useful.
-TonyTony: You can use the motion tracker in the same way to stabilize what you need to roto and then invert your stabilization (with an expression between the position and anchor point) .
I guess I could do a part 2 of this tutorial to demonstrate that, and a few other roto techniques that I didn't have time to mention in this tutorial.

Hi guys,
I've got a biggish roto job coming up, so really fancy watching this...but it doesn't seem to be loading..I'm getting the light blue BG screen and a brief QT logo pop up just before it, but no movie.

Great tute Pete!
The anchor point expression thing came in really handy today on a 5hr roto job of a couple of people jumping in the air legs splayed....Just a shame the client didn't really notice the resulting 3 second animation! Might aswell have used a still! Bah! It's what they asked for though...
The time we spend on the littlest things eh? Will anyone ever notice?!

You want to create an expression using the pickwhip. To activate the pickwhip, you need to alt-click on the stopwatch for the property you're dragging from, then drag. Check the AE help on expressions.
