Alexander Fox put the Magic Lantern RAW feature to the test in a real world production with the Canon 5D mk2 to compare with it’s native H.264 recording format.

RAW files gobble up enormous amounts of storage (about 4GB per minute, depending on resolution), so I needed a short project with simple shots. A web video promoting kids’ tennis was perfect. The kids were only available for about an hour, and I couldn’t afford to waste disk space, so I decided to shoot everything off a tripod, to maximize usable footage, and to avoid the complexity of moving camera shots. Also, I was working as a crew of one, so logistically I had to keep things minimal.

On the 5D Mk II, Magic Lantern RAW has a maximum resolution of 1880×720. It’s an interesting, super-widescreen aspect ratio, but it caused some problems in my initial tests, so I decided to shoot at the standard 720p resolution of 1280×720 instead. Magic Lantern decreases resolution by cropping the image, so the fairly severe crop factor from 1080p to 720p meant that I would only see the very center of the image. I wanted to use a wide-angle lens to give a sense of immediacy and to limit rolling shutter “jell-o,” so I decided to shoot all the action footage with the widest lens I have, a Sigma 12-24mm, and the on-camera segments by the coach with my Canon 24-70mm.

The Sigma 12-24 is not a particularly fast lens (maximum aperture f/4), and it does not accept filters, so I knew I’d be shooting at a pretty high aperture, but for sports, a more generous depth of field isn’t necessarily a bad thing.
