Transition Question

[Bouncing Account needs new email address]

You can use any alpha channel image (a Title, a Photoshop image with alpha, etc) to cut a HOLE (in it’s exact shape) and “Fill” it with other moving (or static) video… all “keyed over” another video track.

V3: Fill clip (what you want to be “inside” alpha)
– Select (highlight) THIS clip on V3, then:
Modify (menu) > Composite Mode > Travel Matte – Alpha

V2: Any “Alpha-channeled” clip (or title generator)

V1: Background clip (will be seen outside the “hole(s)”)

If you end up with the “reverse” of what you want, swap the clips on V1 and V3.
Remember to change the settings (Modify (menu) > Composite Mode > Travel Matte – Alpha) on the clip that is now on V3.

You can move/expand/reposition the V2 clip or even use it as a custom “wipe”.

you can use a grayscale image in the gradient wipe transition to do this. Should be in the manual.

you guys are all talking about a static image though (i think), i’m talking about a clip of moving video, i mean let say that i’ve made an animation as a transition element, but to make it a bit more seamless, i’d like to use the alpha chanel of that same animation, to mask the transition. that’s what i’m talking about, i know about the gradient map, i just thought you could do almost the same but with a moving clip.

Thanks.
