In the Photoshop tutorial, Richard Harrington takes a look at making an alpha channel based upon the luminance in an image. Alpha channels allow you to store transparency in a graphic and transfer that transparency to another non-linear video editing program or compositing application and key or composite in real time.
Hello Richard,
You are great!
Thank you so much.
Cheers!
Is there a way to apply
by David Crow on Jun 13, 2009
Is there a way to apply any of these Alpha Channel creation methods to video in PS Extended CS3/4? Everytime I atempt it I get an Alpha Channel that spans the video, but is only 1 frame. All edits to the alpha on any frame are on all other frames.
I know its probly silly and I should use AE, but I saw this and thought, I want that kind of control.
I've been making alpha channels the same tired way for years and usually with standard to sub-par results. This is a fresh, new outlook on a basic Photoshop activity.
