Keying with separate hi con
Folks,
I have a moving graphic (lower 3rd, let’s say) with a separate hi con. Two separate pieces of video. What’s the proceedure for keying this over a background video layer? Is there a way to marry the fill and hi con together into one file, so I can just drop it over whatever background video I want? (with rendering, of course). I’m doing a show with many of these elements, so I’d love to pre-build as much as I can, and limit the number of video tracks if I can.
Thanks,

I would precompose your elements in LiveType, that way I just save as and change the names as I go.
Hope this helps-

In Live Type? How does that work? Can I marry the fill and hicon together into one video file?

As long as they have alpha channels you can directly import (under edit “place”) and composite them. When you do a save as, LiveType will reference the same files over and over. No need to make them one video clip, it leaves your options open for adding or subtracting elements later without re-compressing again. The .ipr LiveType file will render in your FCP time line, no need to render out of LiveType.

Here’s how it works with multiple video layers:
You can use any high-contrast image (a Title, a Photoshop image, a moving video clip, 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” the “hole(s)”. (Where the WHITE area of the V2 clip is.)
– Select (highlight) THIS clip on V3, then:
Modify (menu) > Composite Mode > Travel Matte – LumaV2: “Hole-cutter” clip or title
V2 can be any HIGH-CONTRAST (B&W preferred) video or CG.V1: Background clip. Will be seen outside the “hole(s)”. (Where the BLACK area of the V2 clip is.)
V1 can be a VIDEO CLIP or a MATTE COLOR.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 – Luma) on the clip that is now on V3.You can move/expand/reposition the V2 clip or even use it as a custom “wipe”.

I appreciate the responses. What I’m asking is: can I turn two clips (fill, and hi-con), into one clip: (fill, with embedded alpha), ala a tga frame.
