create vectors from video

[mbevolution]

im just wondering if any of you experts know a software that takes a video and convert an object in it into motion vectors? For example, if I have an exploding bombshell, I want to select a fragment at the very 1st frame and let the software identify this very fragment until the last frame and create a series of vectors for each frame.

i know if I do it manually I can use flash, but I have too many fragments and too many frames so that would take too much time.

Identifying objects moving between frames is a hard problem. You might have some luck with Fizick's MVTools for AviSynth. But I suspect if the pieces are rotating it will be near impossible to identify their motion.

Edit: Even if MVTools does do something for you, there's a good chance you'll have to write some code to get the vectors in the format you want.

There is software but it isn't cheap. Used in film for compositing live action with cgi effects it makes it where you can track items in a film to align with things you add into the scene. It can do all sorts of things from vectors to algorithms for decoding changes in light generated by particles.

thx guys, ya i was hoping that the new adobe cs5 suite would have some type of feature that does this kind of stuff, lol maybe i can convince my boss to purchase the autodesk for the project, we'll see.
