I want to use a DSLR pro Nikon D3s to record a video and extract the raw data of each frame (like the raw data out of RAW image). So if I record with 24 fps, then I would practically have 24 images (CMOS readouts) and I'll have the data of each frame. How can I do it?

    The video file is compressed, so you wouldn't have 24 raw images. Raw video data would fill up memory cards at an astonishing rate - say 16mb per frame, 24fps, 960mb/sec, nearly 58Gb/minute. That's assuming the data could be written to the card that fast in the first place, which it couldn't. – ElendilTheTall Mar 30 '16 at 12:20

    I don't think so, for the reasons above. – ElendilTheTall Mar 30 '16 at 12:28

    Simply, that's not how video or the raw format work. – Dan Wolfgang Mar 30 '16 at 12:52

    It would be comparable with the LHC data rate – Count Iblis Mar 30 '16 at 12:53

    Cannot be done with your camera. You either need a canon/ML or a black magic camera and similar products (designed specifically for video). – kazanaki Mar 30 '16 at 14:45

Magic Lantern has a RAW video mode - but it is only for Canon DSLR's.
