Extract background from hand
on Dec 18, 2018 at 1:03:38 pm



I have this hand in video and I need to extract the background
so I used extract effect but it worked partly because the hand moves on the background
someone knows how to extract it without doing roto ant work?

You could try a difference key assuming the shot is locked off and the hand clears the frame to give you a clean background. With care, difference keys can help with a lot of the work, reducing the need for roto, but they are less than perfect.

Sorry but Roto or Mocha is your only hope for that.
Anytime you introduce motion it becomes actual work.
No magic buttons here :(

Have you tried just garbage masking off the top where the arms hang in to frame and luma keying the white background out. Maybe you can increase the contrast or play with levels first, precomp and it key that to get a matte? Worth trying before you roto the whole thing.
