Film Riot has created a clever short film entitled U.F.Oh Yeah, Directed and written by Ryan Connolly and starring Josh Connolly, the film is about a U.F.O. enthusiast and conspiracy theorist who has an encounter with extraterrestrials that doesn’t go quite as one might expect. After the film, learn about how some of the effects were made. There are a whole series of videos here and they’re fantastic!!
Post by Andrew Kramer/ Video Copilot: "In this tutorial we’ll use a technique called Depth Compositing to combine stock footage with 3D rendering and the use a Z-Depth pass. This method allows you to place 2D elements like stock footage into the depth of a 3D render. I also demonstrate how to export a Z-pass from 3D max, Cinema 4D and even use Element 3D to output a depth channel."
