Canon 50D Couldn't Shoot Video in 2008. Now in 2013 It's Doing 1080P RAW
Magic Lantern progresses more every single day, and this one is particularly impressive considering the camera couldn’t even shoot video when it was released in 2008. A little less than a month ago, those working on ML managed to get the Canon 50D shooting not just video, but RAW video, and now it’s possible to get full 1080p, even on some slower cards.
This is a quick test of the EOS 50D recording 1920×1080 24p in Magic Lantern 14bit raw video.

Shot on Canon EOS 50D (Yes, the one that came out before the 5d MkII and the one that didn’t have video LOL)
Nikon 50mm F2 (Vintage 1974) – Shot at F5.6 – F11 (The lens is effectively 240mm because of APS-C crop + 3x video crop)
Transcend 600x 16GB CF card
Thanks to a1ex from Magic Lantern for the buffer sorting hack that made this possible on a relatively slow CF card.

If you ever looked in the comments from raw_rec.c, you have noticed that I’ve stated a little goal: 1920×1080 on 1000x cards (of course, 5D3 at 24p). Goal achieved and exceeded – even got reports of 1920×1280 continuous.
During the last few days I took a closer look at the buffering strategy. While it was near-optimal for continuous recording (large contiguous chunks = faster write speed), there was (and still is) room for improvement for those cases when you want to push the recording past the sustained write speed, and squeeze as many frames as possible.
So, I’ve designed a new buffering strategy (I’ll call it variable buffering)
Even though this isn’t using the full sensor, you’d have to be pretty cynical not think that more developments are coming. It’s not going to work any miracles, but this particular development will provide slight improvements when you need to squeeze just a little more write speed out of a card.
Things are definitely getting more and more interesting, and the sky is the limit when we’ve got cameras like the Canon 50D now recording full 1080.
