Rotoscoping and import into motion2

[cdowns]

Evening,
Can you rotoscope, export as color ( or whatever format is recommended ) and then import into motion2 correctly ?

I would like to do:

rotoscope out green screen bleed and cross hair tracking tags.
import into motion2
use DVmatteBlast on the clip.

Ive tried this but I must be doing something wrong. Is there a better way to do this ? dvMatteBlast just keys so nice its unreal.

thanks in advance.

Sincerely,
Christopher M Downs
