Backgrounds /AVIs with alpha channels

[Maxine370]

For the next go around of products, I'd love to see some video clips with alpha channels that can be used with track mattes. Any possiblities for a spinning orb?

[Chuck Engels]

I will put it on the list Beth

Any old orb, or are you thinking along the lines of a spinning Earth, for example?

[Maxine370]

I guess any old orb because I'd like to use it as a matte layer for track matte so video would superimpose over it. Not sure how it will work yet but would love to test it out.

Would this be spinning horizontally, Beth, like a globe spinning from left to right, or spinning as if seen from overhead?

And when you say globe, do you mean a graphic illustration of the Earth?

[Steve Grisetti]

Just another thought, Beth, because you say you want to superimpose your video on it.

What if you used the Spherize effect and then just -placed a frame around it so only what was inside the circle showed?

If you keyframed motion, you could have it move from left to right and then have another clip move in to replace it with its own movement, giving the illusion that the rounded picture was rotating.

Is that the effect you're looking for?

[Maxine370]

Steve,

I'm not sure what I want to do but want to experiment with using video as my matte. Kind of like having the motion keyframing done for me and/or more intricate stuff. I tried some of the motion backs with the luma matte and some looked pretty interesting.

No rush though Chuck. It's not for anything I need per se more to experiment and share.

Does Premiere Pro have the Spherize effect?

[Maxine370]

yes, but I've never been a big fan of it. I did however, use it once to make a globe spin which was cool.
