    simonfilm got a reaction from haarec in Detailed Panasonic GH4 rumoured specs - 10bit 4:2:2 and 4K video   
    And what about Global Shutter?
     
    IMHO in order to compete against BMC 4K they would need to offer global shutter.

    I wasn't sure.. so I looked for it and.. bang!

    this is PB's april's fool in 2010, saying there was a Canon firmware upgrade giving RAW :D
     
    the funniest part is when he writes: "Canon have done exactly what we wanted. RAW baby, RAW! "

    The Canon sponsored people are doing a great job of misunderstanding the technical aspects. Whether they do so on purpose or not, who knows? But it sure as hell is annoying.
     
    Sensor
    Live view is powered by the CMOS sensor. The camera buffer contains raw data from the sensor. The CMOS constantly reads out this data to supply a moving live view image on the LCD. Video came about on DSLRs as the camera could also compress this raw video stream and save it to a card. Since the sensor is already doing raw video during normal live view operation with the factory Canon firmware, there's no extra heat or stress penalty on the sensor for raw video with Magic Lantern.
     
    Buffer
    I think I read this is 512MB RAM at 700MB/s. RAM is also present in your laptop. It is constantly churching read / write cycles as you use the computer. RAM is designed to work constantly. It doesn't die through exhaustion like a mechanical part or the unfortunate Chinese worker who was tasked with making it in the first place.
     
    DIGIC and card controller
    Digic is designed for complex tasks like compressing the shit out of our lovely raw video stream. Now it can sit back and do something else, because with raw, there's no complex computation going on at all as TC pointed out above. The card controller is a simple off the shelf chip designed to write to the card like your $10 SD card reader. It won't blow up. It doesn't have the brains to get too hot!!

    Who cares what Vincent Laforet thinks? What matters is what you think. May I ask, why do so many websites put Vincent Laforet on a pedestal? Why? Just curious, I'm not meaning for that to sound negative.

    simonfilm got a reaction from Sean Cunningham in Canon 5D 2K raw feed update - 1920x720 possible on 1000x card?   
    If a 5d2 can do this, what could we get from a Panasonic GH3?  
     
    "The GH3 has a quad core CPU, outclassing even the dual core DIGIC5+ and assisting DIGIC 4 found in $6000 Canon 1D X." (From EOSHD : http://www.eoshd.com/content/9011/the-panasonic-gh3-is-here )
