I've had no luck getting a good key around a subject with stringy hair. Admittedly, our lighting and setup wasn't as good as it could have been, but I'm wondering if anyone has any tips? I've tried different keying approaches in Final Cut and AE with no luck. I'm not particularly experienced with either program, so I very well could be missing some tactics.
My first tip would be to use Hawaiki Keyer from FX Factory as it can pull some amazing keys from badly shot footage.
Beyond that for a really difficult key you may want to try multiple layers and masks and cutting the image up into smaller chunks and keying just one section of it at a time. Eg. One key for the body, another for the head, another for just the edges of the hair, etc.
