Activity Forums Adobe Premiere Pro Alpha not being interpreted correctly

  • Alpha not being interpreted correctly

    Hi everybody,

    I’m having an issue with alpha transparency in Premiere.

    I have a graphic as a baked QT movie, at Animation Millions of Colours+,with various floating elements of different levels of transparency.

    Picture lots of text whizzing around, foreground and background etc.

    When I import this QT movie into After Effects and composite it over some footage it looks fine.

    When I import this QT movie into FCP and composite it over the same footage it also looks fine.

    However, when I bring it into Premiere CC it does not look fine. It loses some, not all, transparency. I am having to switch the blend mode to Lighten (luckily the GFX are all black and white) in order to achieve a near-as-damn-it, mildly satisfactory compromised result.

    In FCP you could toggle the Alpha between Straight / Black / White, which would often be necessary in these kind of situations, however, in Premiere CC there doesn’t seem to be an option to do this.

    Could somebody shed some light on this for me please?

    Many thanks in advance.

    James

    Did you ever find a fix for this? I’ve had this problem since switching to premiere and still can’t find a solution, my workaround has been to duplicate the graphics layers until the desired transparency is achieved 🙁
