  • Need keying help!

    Posted by Aza Allen on December 20, 2008 at 6:07 am

    I need some help with color keying –

    This video was shot (poorly – not by me) and until I can locate the woman and have more time, I have to try to work with this to get something up on our site soon.

    I have AE 7.0 and it comes with keylight v1.1 –

    Can someone help me and tell me the best way to go about keying it the best way possible? I have a still from it below – it was originally shot in HD (1080)

    Thanks all for any advice I can get!

    P.S. I’ve tried to key it already, but it wants to take bits of her shirt away as well.

    I hate to say it, but you’re totally hosed, I wouldn’t touch this key with a ten foot pole.

    The decision to shoot her in a blue/purple shirt against a blue background was a fatal one. Besides that, the overall color and lighting is so poorly done and skewed towards magenta/blue that there is no hope for getting a good key here. The camera operator shot in HD, but didn’t even white balance the camera?

    Your only real option would be rotoscoping each and every frame by hand.

    I managed to pull an “acceptable” key from your still image. However, as this is just a single frame, it’s possible that each frame will need slightly different settings. In this case, it may be quicker to rotoscope the footage, than to adjust settings on a frame-by-frame basis.

    I would be suprised if that worked, but give it a try.

    What I would do, is pull a really hard and crunchy key, just to fill her in as much as possible.
    Then pull the softest key possible, by color dropping close to the subject. Then masking out any of the remaining blue screen that didn’t key. Try to use the clip black and white settings as little as possible to maintain some edge detail.

    That still won’t give you an acceptable key. But combining that with your roto, may help things go a little faster.
