Roto/Comp Workflow

hehe, seems that we re working on the same shot from pixel corps.
i more concerned about tracking the shape, this is a rod removing shot, and the rod are moving, turning, but when i try to track the rods in motor, i have some weird shifting, when i put the grid on i see some heavy perspective change, but the rods aren’t changing that much.
this is the shot :

may i upload the shot somewhere ?

Hey ludovic! You’re right about working on the same shot. Although I’m new here, I don’t think there’s a way to post your work. However, why don’t you post on the thread at Pixelcorps?

I’ve posted my wip and a resource.
I think the trick is to use the tripod leg as a track, then use that track
to apply to a roto of the part(s) you want to exclude. (see the resource link
that I provided in the pxc thread.)

I’d like to work with you on figuring this out. And what to do after Motor.
See you at

Hey all. I’m new to Rotoscoping. I’d like to know what would be a typical workflow to remove and replace objects in a shot.

I’m working on a tutorial of sorts. I have 2 sets of image sequences.

1- Sequence with objects to be removed
2- Clean sequence with same background no objects.

What I understand, is that I would create roto masks in Motor, then output the mattes, to be used in a compositing app.

Is the idea such that, the offending objects would be
masked out and replace by the clean sequence through compositing?

If anyone can help, I’d apriciate it.
Thanks.
