Can't export quicktime w/ transparent b.g.

I'm having difficulty exporting a quicktime movie from motion w/ a transparent b.g. I've created a name bar with some simple behaviors and filters. View > Channels > Transparent is set. What am I forgetting? It probably makes the most sense to export from FCP and build in Motion but shouldn't this work anyhow?

Make sure that your background is set to 0% opacity and also make sure you are using a codec that supports transparency, i.e., animation. If you are using Motion 1, you need to dig into the settings to set it to "millions+" (the + means the alpha channel); Motion 2 has an alpha channel preset you can use.

or, You could import the "motion" project directly into the FCP timeline, thats just like the other media file could.

Also make sure when exporting an Alpha Channel to set the Alpha to "STRAIGHT" and not "Premultiplied" for a clean matte.
