    Hi folks,

    in detail I’m asking for a clip like this:

    Is it somehow possible to seperate the pullover/sweater from the rest of the clip to colorize it? I’ve tried a lot of things.
    – Keylight 1.2
    – Color range
    – extracting it with Levels and Auto trace
    – and many more

    but nothing worked in an adaquate way.

    Maybe here are some professionals who can tell me how to extraxct the pullover/sweater in a perfect way to recolorize it and also finally have an alpha mask of it.
    This have to work somehow! No problem if you use 3rd Party plugins…simply name it. Our agency is able to buy them!

    Hey Stefan,
    Keylight does not key white/grey/black, only colors. There are other plugins that do but I don’t think this particular clip will key very well. You can try it for yourself though.

    Keying > Extract
    This plugin is native to After Effects. It clips the White/Black of the image into Alpha (like crushing the blacks but the crushed pixels become alpha).
    Red Giant Primatte (Keying Suite)
    This keyer will key Black/White (as well as color) and has some interesting features that keylight does not
    Composite Brush
    This might be your best bet at an automated solution. It’s a new plugin that is producing the best results I’ve seen yet. I don’t know that it will be able to extract her shirt but it’s worth trying. (

    If you can’t get a clean automated solution, the sure-shot method is to rotoscope the target area and treat it on its own layer.
