    I'm guessing that's a typo, a 2 instead of a 3.

    Could be, did not think about that. 

    Ok I will wait for the canon announcement before any conclusions.

    I do want canon to make a nice 4k camera, because the autofocus is so good.


    32.5mp APS-C Sensor

    DIGIC 8


    RAW burst to 30fps

    Up to ISO 26500

    Eye detect AF

    AF capable down to -5 EV

    4K video

    FullHD at 120fps

    Removeable OLED viewfinder

    What does 4k though image processing mean canon?

  3. What I can say about compressed raw is:  

    Stills cameras had a form of compressed raw already before Red made it version.


    I used to have a Nikon D70 and the Raw files were compressed.

    So what I try to understand is what makes the compression on a series of stills at 24 frames per second so different than the single images?
    It is the same single compressed frame just more of them.

    So In my view the patent should not have been granted.  

    only the compression algorithm could perhaps have been awarded a patent.
    But if this was just a form of jpg2000 I don't see why they would even need to get a patent for that.

    I know the S1 is not approved for Netflix but it could be based on the requirements, it would have to be with an external recorder for the I frame codec and data rate requirement.

    Camera Requirements

    Please note, not all cameras that meet these requirements will be approved as primary cameras. These requirements are the minimum specifications necessary for consideration. Other attributes must be taken into account such as dynamic range, form factor, stability, workflow compatibility etc. 

    Resolution Requirements:

    Camera must have a true 4K UHD sensor (equal to or greater than 3840 photosites wide).

    Capture Requirements:

    Capture Format

    RAW (Sony RAW, REDCODE, Arriraw etc.)

    COMPRESSED (XAVC, ProRes, or other I-Frame capable formats)

    Minimum of 16-bit Linear or 10-bit Log processing

    Minimum data-rate of Bitrate of 240 Mbps at 23.98 fps 

    Capture Transfer Function

    S-Log3, Log-C, V-Log, Log3G10, etc.

    Capture Color Space

    S-Gamut3.cine, RED Wide Gamut RGB, Alexa Wide Gamut, etc.

    No looks or color corrections should be baked into the original camera files.

    Files must maintain all metadata (i.e. Tape Name, Timecode, Frame Rate, ISO, WB, etc.).

    Anamorphic Lenses:

    If anamorphic lenses are being considered, camera selection must take into account the extra resolution required for capture. Contact your Netflix project lead to discuss implications or concerns.
