  Lower Third Rendering

  Posted by Toby Rocke on July 13, 2008 at 3:03 pm

  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!

  flash only supports premultiplied, just in case.
