lock Transparency
I have a shot of a flock of birds. I want to make a mask from it.
I have got the birds cut out from the sky ok using levels and colour range key etc. In photoshop I would probably lock the transparency and then fill the left over with background colour for a sharp single tone mask.
Is there something similar in AE. I mean to lock the transparency ?
If that makes sense or am I being remarkable dumb ? (It would not be the first time )I just wondered cuz I could not find anything in the help file. I have
6.5 pro btw.
Cheers
