    Wondering if anyone has taken a live shot out of the 7D over HDMI and brought it in with a Black Magic Intensity card. I have a studio environment that I am working in, and I am wondering if I can get around the 12 minute limit that the memory card is giving us…

    First, i don’t own a Canon cam, but an educated guess:
    From what i’ve understood, the HDMI output is crippled during shooting.
    So no, it won’t work.

    Next, the 12 minute limit from the card is not the card, but the way it is formatted. (fat32) The H264 runs at app. 5 MB / sec.
    So after 12 minutes, the 4 gig file size limit of Fat32 kicks in.

    So for longer recordings, this is the first thing that should be concidered.
    (Normal video cams overcome this problem by making multiple files and merge them one way or another.)

    So i think you have to ask Canon for a firmware upgrade.

    HDMI watermarks the image with a giant red dot….

    C’mon, Rich – you’re pulling my leg! 😉

    Check this out (the last minute in particular – he finally figures out the 7D controls . . .)

    Is this for real?
