I have recently been experimenting with the RAW video capabilities that come when you install Magic Lantern, a custom firmware for canon DSLRs. I was shooting RAW video on my Canon EOS 700d. In order to write .MLV RAW files to a 60mb/s SD card, the resolution had to be lowered to 720p. Working out how to then post process these files was very challenging because of the strange artifacts I got in the video file on the 700d. However, eventually I managed to figure out a complicated but not too ridiculous workflow that gave me the above results.

It was definitely worth all the difficulties because you basically end up processing sequences of DNG files, so you can colour correct as you would with a RAW photo. The amount of detail in the image and control over it is amasing.
