Travel Matte

[tharding]

Is it possible to have a Travel Matte?

for example:

Layer A is a background such as a sky
Layer B is a black and white image that acts as a mask
Layer C is a different clip which only displays in the black or white area of layer B

My specific application is projecting onto a 3d set that has a cutout shape in the foreground. I would like to project a different image onto the cyc in the background and be able to project another layer inside a mask that is the same shape as the foreground cutout.

i cant think of the best way to do this right now.
it depends on your content and what is foreground and background.

can you post a diagram here of what you images?

you can use movies with alpha channels if you use the animation codec in millions of colours+ mode.

Best explanation is probably in the Final Cut Pro manual Volume III

toby.

can you draw me something of what you are actually trying to achieve?
- im trying to help other people as well.
this is something that quite a few people have asked for.

but there are sufficient variations - that not every solution works for everyone.

Hope this explains it.

Ideally the mask layer could be any one from 2 to 7 and every layer above that would appear in the mask.

That way you could have layers 1 thru 4 as background layers appearing as full screen. Layer 5 as the mask for the alpha channel and then still have 3 layers to muck around with inside the mask.

i will see if i can come up with a simple way to do this.

Travel Mattes would be cool. They're simple to do in After Effects.

Remember that the matte and the subsequent layer move with eachother.

This is my most needed feature. Most broadcast logo work is packaged as with a travel matte so that the logo can be layered on any background.

You could do it as a luma matte instead of alpha if alpha is still troubling you.
