Using a slow cf card at only 133X to record raw dng video from the Canon 5D mkII,
I was able to test the workflow involved, the new grading capability and check the resolution of the raw files.
I was able to capture longer files mostly at 1280x720 and 1880x720, also short clip at 1880x1080 the Highest resolution the Magic Lantern can extract from the sensor of the 5DmkII.
Still Alpha stage, this wonderful firmware hack is still evolving, as of this posting, as the Magic Lantern team continues to tweak the code they have custom compiled.
A faster 1000x CF card is required for longer sustained recording and higher resolutions.
This video shows a lot of shiny items to test for highlight recovery, a few detailed stuff and resolution charts at the end testing different resolution and also showing the importance of the mosaic VAF filter on the 5D mkII even when shooting raw.
