Turning a movieclip into a bitmap

Hello ).

There´s a way to turn a movieclip with a complex shape into a bitmap so I can do a BitmapData.hitTest

seeing what are the non transparent pixels colliding between two bitmaps?

This is about a complex hitTest. (Yes I didn´t finished yet )
I´m trying to make two movieclips turn into two bitmaps so I can realize if there´s a way to

see if one of the first bitmap´s non transparent pixel is colliding with the second bitmap´s non transparent pixel.

Thanks
