Blackmagic RAW Support

As someone who uses this codec, I would love to see this added to the list of available codecs that would work with Blender. It's extremely robust yet lite for a RAW format. I believe Grant from BMD said he's making the API open for any program that wants to use it.

I also do like the idea, but I would generalize it to have raw video support in blender. Because there are other formats like CinemaDNG. Currently Blender relies on ffmpeg, so everything ffmpeg can do, Blender also can. This would have to be changed to a more generic video input handling to sopport other codecs also. And for RAW codecs, debayering and input curves or LUTs would have to be added.
