Compositing SFM renders into external footage - experiment

I wanted to see how well I could take stuff rendered in SFM and composite it into external footage - in this case, a random image, but the principle for video is the same. The next step I want to take is to get motion tracked camera data into SFM, as well as shaped shadow catchers to get the SFM character to cast shadows onto IRL props

Damn this is pretty helpful
