    Lower Third with Alpha Channel Question

    Posted by Sandra Miller on September 28, 2006 at 6:05 pm

    Hi there!

    I have created a company logo for a lower third to be on screen during a video. When I export to an avi, selecting rgb+alpha, my logo is rough and jagged on the edges. It is an uncompressed avi file. Is there something that I am over-looking during my export? My lower thirds that I created for my names look great and have the same settings.

    Thanks in advance!

    Thanks for getting back to me! I have seen the straight and premultiplied settings…if you don’t mind me asking, what is the difference between the two of them?
