Transparent Layers

[vickero007]

I want to make a logo appear on top of the video when the video start and then fade from it's color (navy) to an opaque smokey color as it shrinks to the corner where it will sit the rest of the time. I'd like to do that using 20 or so Photoshop PCT files but I don't know how to do the Alpha channel part.

I can't use a Blue or Green Chroma because when the image fades to that opaque color it becomes too similar to any color to use a Chroma key.

Could someone explain in great detail (menus and such) how to create the image with an alpha channel as a background that would then be removed in Premiere?

Make your logo on a layer above a background in the same aspect ratio, and at least as large, as the video project size. Don't take the pixel count, use 4x3 or 16x9, because stills use square pixels and DV uses non-square. Premiere will keep geometry correct if you use square pixels in stills.

By importing just the logo layer, not the background, into Premiere, you will get automatic alpha channel transparency, which will be automatically applied on the timeline if you drag from project to a superimpose track.

You may find that you can apply an effect (or maybe more than one effect) to your still overlay in Premiere to get the animation you want from a single image.
