Transparent Background
on Feb 17, 2007 at 7:23:27 pm

Hi: Working with just making some simple titles in motion and having trouble getting the background to be anything other than the default black. Here is what I have tried:

Changing the project properties to 0% (open apple + j) and exporting out as a QT File, then imported into FCP and still saw the black background in the timeline

I can't find anything else in the online manual about transparent backgrounds.

Thanks,

JOE

Okay, perhaps you need to export a QT file (not sure why, but maybe). If so, I'm not sure what the problem is.

If you don't absolutely need it as a descrete element in FCP, do the following:

Save the Motion project.
On the top of the canvas window is the name of the project, with a little page icon on its left. Grab this so that it comes loose. Don't release the mouse.
Apple-Tab to switch to FCP and drag it onto the timeline. Release the mouse. Render and be amazed (this is called Round-Tripping).
If you need to make changes, select the Motion clip in the timeline, right-click and select Open in Editor.
Make your changes and save the revised Motion project.
Tab back to FCP and the changes will be there.

If memory serves, this feature (Round-Tripping) works on FCP from version 5.0 on.

Good luck.

Ken

I am on the above post for DV matte blast help and just tried the "roundtrip". No audio came in with the clip and after rendering I have black canvas and viewer windows

I got the round trip to finally work, but even when you set the background to 0%, I am assuming this is to get no color at all, there seems to be a hint of something that is very slightly non-transparent when I import into FCP. I keyed a person with DV Matte Blast and put a background of the Rocky Mountains (in FCP) and rendered. I can still see the the slightly non-trasparent background that came from motion over top of my background.

Did you try exporting it as "Animation" lossless + alpha ?

Try using livetype instead.

The other thing you can do is drag the clip from the timeline into the browser and then experiment with different Alpha settings (scroll to the right).

Good luck.

Thanks Ken,

It took some playing, but the roundtip method works the best for a transparent bacground. I think I didn't have my background (playing with red and green spill etc.) as transparent as I wanted. When I drag back to FCP and render things look pretty good. For digital keying that is. I think DV garage should explain the process a litle better. They have great tutorials, but no instructions and I have had three emails never returned when asking for help.
