    hello once again to the awesome creative cow community,

    I am exporting some titles made in after effects. the title cards are several single text objects in a single comp (writer, director, producer, etc). i also have a sample project for a title crawl, kindly provided by a user at a REDforms. this has the necessary expression for smooth movement in 2k and 4k comps for crawling.

    my goal is to export a quicktime and then import into avid media composer. I would like to add alpha channels to the title cards so that they may be displayed over picture rather than black, then the crawl will be over black. how do i add alpha channels to the text objects themselves (the title cards)

    Just make sure you don’t have a background for your text. Turn on the transparency checkerboard. Where ever you see the checkerboard is what is transparent.

    Avid’s DNxHD codec supports alpha channel as well as Quicktime Animation and ProRes 4444.
