Question about using Subtract and Divide Tutorial
on Aug 27, 2010 at 8:37:09 pm

I have a triangle shape that I am moving around on screen and I also have some footage in the same composition. I am trying to use the tutorial to get the footage masked around the edges and just inside the triangle. I'm basically using the triangle as a matte. During the animation the triangle is rotating a little bit and it is also scaleing down quite abit. It's a big illustrator file at the moment...

So I have the tutorial working at it's most basic level but as the triangle scales down I want the footage to scale down as well keeping the matte as the same scale properties as the scaling down triangle. However when I scale down the footage it scales down the matte with the footage's scale properties. How can I fix this? Any solutions are greatly appreciated. And If there are easier ways of doing this plz let me know. If you need to see a video Of what I am talking about I can post a link.

Thanks!
Ryan

If I understand you correctly, the fix is simple: parent this footage to the triangle. When the triangle scales and moves, the footage will scale and move as well.

It is parented to the triangle and it moves and scales with the triangle however I want more of the scene to show up in the masked triangle and I think doing this is a completely different thing. Because right now I have the matte effect on the footage as it is in the tutorial but I'm also scaling down the footage. I have an example of my project here with the faulty effect:

As you can see I want to start it out with the triangles at 0% opacity where you can see the right color balance on the footage and then as the triangles scale down it fades to 100% opacity. I hope you have a solution. I believe something like this is pretty easy to do I think I'm just missing a couple of steps.

If someone could help me out that would be great! If not I may have to take a new aesthetic direction in my project.
