  Render Alpha as a Black & White Matte

  Posted by Jason Mckee on October 12, 2011 at 10:05 pm

  i have a client requesting that I do the key on the green screen footage that they shot and then I just send them a black and white matte of the footage (so they can then use it as a luma matte). they don’t want the footage with an alpha channel. i know this can be done, i’ve never been requested to do this before and I’m curious to find out what the best way to do this is. thanks.

  Add the “Alpha Only” output module in the render queue.
