Lower Third Rendering

Hi all!
I actually have a sensible question for you.
I have been asked to produce some lower third straps for a new video podcast.
I can get the graphics to do exactly what I want, but how do I go about rendering these out to retain the alpha channel so that they can then be imported into FCP?
I've tried a few methods. The most success I had was with a PNG sequence, but when they imported each one sat for about 2 seconds and did not look good.
This may not help, but I'm not the one using FCP and I am unfamiliar with it.

Hi Toby,
After you add the composition to the render queue, in the Output Module Settings, set the channel to RGB+Alpha. Depth should now have a + symbol next to it. For the colors just choose pre-multiplied or straight depending on your case.
When you render out the alpha channel will be included.
Hope this helps!

Use the Animation codec, best quality, millions of colors+, RGB+Alpha, and STRAIGHT (i.e. NOT premultiplied). I use it all the time when I make alpha-channeled animations for FCP.
