I need to get an alpha channel on an image
I’m cutting out a magazine image with Illustrator and I need to bring into FCP. I’m thinking I have to take to Motion first to get a decent alpha channel. So, in motion how do I do this? Then I’ll export for FCP and bring into my timeline to key. Taking it directly into FCp doesn’t quite give me the keying I need.

How about Photoshop or After Effects? Motion will work too, I just don’t know how well it works with illustrator files.

Can you be more specific? When you say “cutting out” do you mean as in rotoscoping, ie. following the outlines of specific element in the picture, or just around the edges of the entire picture?

we usually use AE, but we have not installed it on the new Macs. So, I guess we’ll have too.

Just take, say an image and want to crop and then key over video in FCP. ANd we need the alpha to cut the video better.

I thought so… Just put you entire still on the upper-most layer in FCP and crop using the crop features in the motion tab. No alpha needed.

It looks thin in HD unless you add an alpha channel.

Now you’re bringing up memories we all tried to get out of our heads. This is a grab from the clients website. I want to grab it, crop it and then fly it around over whatever crap they want in the back ground. And Motion should cut the video better then anything else. I could do a composite matte in FCP but I think it won’t do the same.
