    How is the Kinefinity able to do this with their $6,000 camera and RED can't do it with their $50k cam.

    this is crazy.

    This again leads me to believe software issue over hardware.

    I know part is oversampled, but the high speed isn't.

    RED's max frame rate on their lowest end current camera at 4K HD is 120fps.......

    And there is no hit on DR, which is important if we are talking something like the Varicam....

    It is not even UHD for the 100fps
    I thought Kinefinity was dead as viable digital cinema camera

    They are claiming NO CROP sensor though. the 4k high speed is using the whole s35 6k sensor. Outputting high frame rates in prores and Raw. (74fps)

    Go look at the photo again. They are getting FULL SENSOR (6k) downsampled in cam to 4k higher speed(74fps). (even when the 6k cannot record at those speeds.)

    check it out. Also they are able to get RAW (not prores) 4k uncropped S35. (oversampled)

    What I'm saying, is that this achievement begs the question is our camera able to achieve something like this? having a 6k image (uncropped) downsampled from the 8k full sensor in a high frame rate in both RAW and prores. (so maybe around 60fps) using the WHOLE sensor not cropped.


    check it out Phil. or am I wrong.

    Well, my 5D Mark III with Magic Lantern shoots RAW in MLV format (transcodes to CinemaDNG) in Full HD using the whole sensor

    The biggest aspect of "proper full pixel raw" in terms of high speed recording is you are limited by the sensor technology's actual readout speed.

    From what I can read you are wrong, and what they are saying is 4K "Oversampled" isn't available in KineRaw. It is in ProRes. Just like what RED does. The other 4K from what I am reading is a crop of the sensor and they list it as M 4/3. Which is the same as what I saw earlier this year.



    On a side note. What RED has done is focused on what the "most" they can get out of a sensor technology. And by that I mean they are tapping into the sensor tech to achieve the most possible captured dynamic range as well as the best color they can extract. There are interesting things you can do with a sensor for instance by "where you put things" and limiting some of the DR, but that's a different direction.

    4k RAW from full sensor 8k Helium would be a dream...just sayin...

    Its not same thing, even Alexa cant output raw from whole sensor without cropping.

    I forgot if the 5D pixel bin's or line skips to accomplish that?

    But either way, that's not something you want your cinema camera to do.
