What u guys think that is the most fastest way, change all of the shape nodes of the entire frame, than compare it with previous/next frame or change a couple of nodes than compare with previous/next, than go back to same frame, adjust another couple of nodes than compare…???
Thanx

There is a good Roto tip in the tips section.
I personally look for large changes in motion and place keys there, then look for funny edges and whatnot.
But I’d go shape by shape versus full frame versus full frame. Easier for me to focus that way.
Use multiple masks with per vertex soft edge falloff, do a rough ajust and then start to clean everything.
Depending on the shot you might use a combination of several keyers, it’s tricky but sometimes might save you some work.
See ya,
dgI also use multiple masks. How many depends on the subject and its motion. I first analyze the sequence with respect to extreme motion points. at those points (usually where the motion of that part reverse), I set a first key, then I’m looking for another extreme between or simply set another key half-way or I adjust the animation curve.
a lot depends on the footage and I fully agree with dg., using multiple masks makes the job easier and faster done.Rayk wrote:I also use multiple masks.

Use as less points as possible and when you animate them they have to move with their object. for example: the spline-point on the knee has always(if possible) to stay on the knee. If not your mask will start to behave like a curtain.
there is a nice tutorial at :

officially it is for digital fusion, but the strategy is the same in any package.
Thanks Tom. I’ve been trying to do it the hard way for wayyyy too long.
