Mask background of SWF

[oshen]

I received an swf movie of a rotating brick with a blue background. I converted to fla but the blue bg and the brick are considered a single object. Is there a way to mask the bg without having to export it as single frames and masking in ps?

[whispers]

this 'may' help..

but last I recall it was for .flv (video)
