I trying to reuse mask in AE (CS3) without copying them. I mean the following:
I have several videos to be masked by the very same mask. I would like to avoid having a "mask layer" for each video (there are like 200 videoclips).
It would be perfect if the same layer could be used several times.
I'm projecting the video result on a wall and I'm using these mask to cut the clip in such a way it fits a shap on the wall. Each installation the wall is different, so even it is ok to re-render the video each time the installation change its place, have to re-shape 200mask layers is too time consuming! If I could re-use them, only re-shaping one would be enough
I have look thruogh the threads but found no one that could help me
Uhmmm sounds cool. Let's see if I got it right:
I make in a different (pre)composition a mask with all the mini-mask I want to use. Then if I need to change something, I can do it in the pre-composition only once. Is this OK?
This will help but does not avoid copying the precomposed mask as many times as clips I have, does it? Even this is is great advance, it would be better if I only had to have one mask for all the videos
Thanks a lot indeed!
It seems that you understand. If you're not clear on how track mattes work, be sure to read the page that I pointed to in my previous post.
