Movement Match?
show user profile  ugtv.org
My first guess was to do this with Camera Match, but the more I do, the more I think I'm in the wrong direction.

Here's the deal :
I have a .mov of a standup comic holding a microphone.
I want to define the area of the microphone and create a 3D Dijery do to put over it, so every time the microphone in the movie moves, the 3D dijery do moves as well.

What should I be looking up to do this?

Boujou does this very well. althought it might be hard if you have no visible background behind the microphone. also it helps to have as high quality video as you can.

Boujou is not free, but if you can get it I would recommend it.

did this couple of years ago, without a tracker program.
She had nothing in her hands. As long as the shot doesnt take too long it's doable.

Workflow :
putten a box aligned to the position and rotation of her hand, animate it first every 10 frames or so
then gradually untill you got 1 frame a sec. Then render and finetune it in a compositing program.

Boujou is way overkill for this! Why the heck would you recommend a $10k piece of software for a simple matchmove? You can get SynthEyes (which is used by ILM, Blur, The Mill, and Zoic, among others) for $400. Try it out here:http://www.ssontech.com/

Or if you want to save your money, give Voodoo a shot. It's free!http://www.digilab.uni-hannover.de/docs/manual.html

I'd tell you but that would break the Maxforum Rules.

Or you could just hand track it using the 2D tracker built into max

"I'd tell you but that would break the Maxforum Rules."

Yeah yeah, my point still stands. Boujou is an earthmover, he just needs a shovel.

It seems like most of these solutions are camera tracking solutions. I really want an object track, where the camera doesn't pan, but stuff on the screen moves around and I want something to follow it. Is there anything like that?

I just found a thing in the manual about object pinning. I'm gonna try that.

I got very far with camera match, and the trackers are all doing great, but when I do the object pinning the 3d items get scattered. I don't need any fancy camera moves, but I think the problem is my main camera is not synced up to where the camera match thinks it should be. Is there an easy way to tell the camera, go here...

Thanks.

It's not very complex. It's 369 frames shot from about 100 feet away. No dollys, no trucks. Just a little bit of panning from left to right and up and down.

[edit] OK, I think I've got this figured out. I was resisting it, but I wound up making CamPoints. So the deal is you have to make your cam points with the exact dimensions of things in the real world. Then with Camera Match tell Max where in the movie those spots exist. It's a little weird because you can't always depend on the movie when placing your Cam Point helpers. You HAVE to depend on the math.

Hopefully this will help someone in the future.
