You can choose the key out the color white instead of green or blue, although you're likely to end up getting rid of other white segments of the subject as well.

Go to effects and use the remove white background effect.:Drogar-Dum(DBG):

You can try to use a Luma Key as well.

you can set your footage to multiply.

and if its too dark or faded, then just duplicate and lay it over its self to make it thicker. but u still might have to do some adjustments.

thanks for your responses, by the way, if i remove the white background whit Key... there also going to remove the light on character face to, or wherever this whit light be...so i dont think its a good option i guess...then if i using luma key...this not work only whit an alpha channel? i guess my last option its to do what Masta-T says right? thanks a lot.

Luma key as msconce suggested is the closest you are going to get. You may have some luck with the Extract filter. Main problem trying to key out white footage is there is no color, and so you are reduced to trying to key out (in 8 bit domain) a few shades of a 256 value pallet. That's not easy.

You may (in addition to Luma key) want to thing about rotoscoping. Yes, the dreaded rotoscoping. Hours and hours of tedious mask tweaking. Sometimes, it's the only way.

Unfortunately I vote roto. Its the only guaranteed way you'll get a clean extract of your subject.

you can do a really rough rotoscope around your character, like 7 or 8 points, and do rush it, adn then close it
select the inverse, and remove all the white with the key, this way you wont touch your character

give it a big feather
