Transparency delema

hmm, how to put this..

Well I came up with an idea for a video, and for several segments, I was going to have this effect. Problem is I don't know how to quite pull it off.

So bare with me while I try to describe it as best as I can.

the image below is just a simple representation. What I want to do is to make it so that the black is one portion of video, and the white is a whole other portion of video, but just like that. I'm trying to make it looke like a clipped window (the black) with a burnt/choppy/torn outside, while having another portion (the white) active behind it. The only way I can think of doing it in premiere, which can't be done, is to use a double transparency on one image/clip. but of course for obvious reasons, premiere won't allow it.

I know it can be done, but there is going to be multiple variations of the black portion I want to make, so that it goes with the beat of the music (about 20-50 variations) done with some wonderful frame by frame editing (oh joy).

what you did is a good start. If you are using premire this is easy.....kinda. You can use that image you made in photoshop and do what you want to do. The thing is you can only aplpy one matte to an video segment at once. Video that you want to be on the outside, or the overlap portion must be in video 2. right click and go to options->transparence. Then choos ethe image matte option
find that image and thats it. Put the background video in video1a or 1b. Thats pretty much it. With you wanting to do this a bunc of times you will just have to razor the video clip a bunch, but it is the same process.

Take all 20 - 50 stills and put them together on the Premier timeline. Export a lossless AVI, uncompressed or huffYUV.

Import that AVI into your main project.

Clip A = Clip with burnt effect
Clip B = Clip behind burnt effect
Matte = AVI you just exported earlier.

You have three tracks.

Track2, 3 & 4.

Place Clip B on Track2.
Place Clip A on Track3.
Place Matte on Track4.
Setup transperency on Clip A for "Track Matte".

;O

You should be all set.

hmmm oh :O

I think a image matte would work best in this situation actually, unless you wanted the matte to be animated. ;o

I considered making a bunch of separate clips, but I'm trying to find a methode that will save me some space..
