CS5 rotobrush question
I’m just dabbling with the new Rotobrush feature in AE CS5. I just wanted to make sure that I am getting this flow correct. After I finish rotoing what I need done, and tweaking with it whenever the roto is off, I hit “freeze” to render it out onto it’s own layer? So If I wanted to use the roto layer as a mask for the layer underneath what do I do? I’m trying to do an overly-used skit involving lightsabers and the Andrew Kramer preset. Sometimes the lightsaber will pass behind the subject, and so I need to mask out the subject. I figured that I can use the new Rotobrush to my advantage. THanks guys

I don´t know your outcome but I risk to say I would use a duplicate of the “roto-tooled” image (tinted black or white) as a mate for the saber.
Hope I´m not talking nonsense.
Cheers!

The workflow with the Roto Brush effect isn’t really any different than the workflow with any transparency-creating effect (e.g., keying effects) in this regard. By using the Roto Brush effect, you create a matte. You can use this layer as an alpha matte for another copy of the layer.
