After Effects – Masking
by David on Apr.17, 2010, under After Effects
To mask,
on a layer, click the pen tool. – make sure it’s ‘closed’. turn off roto bezier (*that make sit need to be close)…
Click and drag if want but click points on it to create mask. Make sure it’s ‘closed’.
Click and hold on the pen tool etc. like in photoshop to get the add and minus tools..
once finished, zoom right in and choose the general arrow and you can move and adjust all of the points to make sure they are as good as possible..
use the Ctrl key to allow you to manipulate individual mask points.
Effect -> Adjust -> Curves… to adjust all the colour and make it black and white type thing..
