Hi,
This should be a really simple effect to do, but it's proving otherwise. I have a square poster that was shot nearly full frame atop a patch of grass. What I need to do is matte out the grass, shrink down the poster and composite it flying around frame in another shot. In any other compositing app, I would draw a matte around the poster, shrink it down, composite it over the other shot and animate it. But, you can't do this in Avid without creating a lot of unwanted effects. How the heck do you do it without having to renaminate an animatte effect around the poster in the final composite every time you want to change the animation?
Do you have any third-party plugins (BCC, Sapphire, etc) or do you have to do it with stock Avid effects?

No third party plugins. Just stock effects.
I'm just shooting blind here because I can't see your picture on the grass, but can't you just us the 3D effect, crop it and then animate it on the shot you want to composite it onto? I'd go with the simple solution first to see if it works before trying more involved workflows.

Unfortunately, it takes more than four matte lines to matte the poster, It's got all sorts of little edges on different angles.
Grab a still frame from the cleanest (squarest) frame you have of the poster. Take into any imaging (Photoshop) software and cut the poster out. Save as a .png with a transparent background. Import and animate to your hearts content.

Why not just put 3D Warp on it and crop out what you do not want?

Thanks for the suggestion, Andrew. That does require third party software, but at least it's an idea that doesn't involve Borris. I wish Avid would allow you to use animatte earlier in the effects chain. The logic behind Avid's ordering of effects is the thing that puzzles me most about the program.
There is a way, but is a pain in the proverbial:
1. Make a freeze frame of your poster.
2. Splice it in the timeline and add an animatte effect and draw the matte.
3. With the animatte effect still in FX mode rt click, and select "Export Matte PICT."
4. Import the PICT with the alpha set to do not invert.
5. Splice the matte clip into the timeline on V2 and step in, replacing the graphic fill with the freeze frame.
6. Promote to 3D and fly it around.
Do you really want to fly it around?
It ain't the 1980's...
Thanks, David. These workflows are crazy!:-) Things need to change.
