Clip Matte on a video

Hi.

I have a video of some pyro FX that i would like to add to my TM scene. It is a 1920x1080 video with a black background and the pyro FX in white. If I wanted to add it in After Effects, I would use the video as a Luma Matte to make the black transparent, and in Lightwave3D I would use a clip matte on a polygon that was the same ratio to make the black transparent. Is there any way I can do it in TM? Thanks
