I'm trying to composite a handful of shots filmed on a handheld camera. Tracking by hand's really not that difficult. What I've been doing is lining up the center square on the animation quad with one of my tracking markers, and then going through and keyframing a move every few frames. This works fine for the motion, but it only works as a final solution when the tracking marker is roughly in the middle of the frame to start out with. So my question is; is there anyway to, after keyframing a motion, position the quad on the first frame independently of the key frames. This way you'd be moving the whole animation, and not just changing the first key frame, if that makes any sense.

Or if anybody has a better method for hand tracking, that'd be helpful too. I can't seem to find anything useful about the subject anywhere.

I was gonna make a tutorial about this a loooong time ago but ran into problems with screen capture software.

I now have a pretty decent screen capture prgram so I'll get to work on one.

Would you mind typing up a brief summary of the technique? I might be able to get it without pictures.

I hate to seem impatient with a double post, but I need to get this project done as quickly as I can. I improved my method so that it works fine when the camera just wobbles a little, but there's one with a big move that I'm stuck on. Is there no way to temporarily turn off keyframing so I can just position and scale the video clip? Is there something obvious I'm missing here? I've done some Googling and found nothing, watched the site tutorials, fooled around in the program, and I can't see a solution, short of starting with a backdrop that's much larger than I ultimately need it to be, but that's not an option at this point.

I wasn't referring specifically to you. I just figured that since the thread was dipping to the bottom of the page, I'd bump it with a little situation update to see if I could score any other advice.

Oh man, sorry.
That was a joke but now that I read it again, it sounds harsh.
My fualt.
But yeah man, I should be done pretty soon.

EDIT.
Could you post a link to the shot that's giving you problems?
That way I can cover it in the tutorial.
You see... I've tried several different ways to speed up hand tracking.
Let me know if you can.

I can't link the exact shot. I could go film a shot of a forest or something with a camera move that mimicked the one in question. Would that work?

Yeah that would be great.
I actually just finished the tutorial and will post it in a few minutes,
I just had to edit out some dead air in the video.
