Probably a lot of you already heard the news, but there are some very interesting things going on for raw video.
14 bit compressed(lossless) raw
And now it even works with lower bit depths (unfortunately that is on the 5dIII only, )

This could help for longer raw video recording times, or continuous recording on high resolutions.
For instance, max resolution (full frame, no digital zoom) on the 6d is 1824 x 1026.
With 12 bit compressed raw that would give about continuous recording times.
Or about one minute recording time in 11 bit 2400 x 960 resolution in zoom mode.
Does anyone here has the knowledge or the knowhow how to port this to the 6d ?
The source code is in the compressed raw branch:
https://bitbucket.org/hudson/magic-lantern/src/ad3969261ccf44db198ae01d863ec3062d9d640e?at=compressed_raw
It's in the silent picture module:

Some info about the process TwoInTwoOutLosslessPath:

And some info about development for it on the 5dIII:
http://www.magiclantern.fm/forum/index.php?topic=19300.0
On the 5dIII there is some improved crop recording mode for achieving the higher resolutions for 4K, this newer crop recording isn't yet developed for the 6d, but for as far as I know, the compressed raw part can be used separate from the crop recording mode.
Some more guiding:

No idea of how to port this, but if needed I will be glad to help with testing.
