The guys at no film school have done it again. In a recent guest post by the awesome director, Rubidium Wu they show you how to make a cheap DIY multi-camera video rig. The cool thing about this setup is that you can shoot multiple focal lengths in one take giving a similar ascetic to Tommy Wiseau’s in his 2005 film, The Room. Having multiple cameras / shots is a must for any shoot whether it's for B-camera, context, continuity, or simply variety.
Shooting more than one angle or focal length at once used to be a privilege reserved for high-budget productions, but with the proliferation and accessibility of modern cinema-grade equipment it's now possible for smaller-budget productions.

Rubidium's setup (above) makes use of a Canon EOS 5D III and Black Magic Pocket Cinema Camera mounted together with different focal length lenses all attached to a MōVI 10 stabilizer. He created this setup for a project called Crow Hill (currently funding on Kickstarter).
Shooting multiple angles at once has its advantages what DIY filmmaking solutions have you and your crew come up with?
