    Here is file analysis. 35Mbit for 24H, with GOP of 6 and 30 minute time checked.

    greeches, the gop is set to twelve in that shot. Is that the right one?

    Do you get the low bit rate frames at the beginning with this setting? Your picture is too small to tell. Looks like we are both in the same area(NC). What lenses do you have?

    Yes, I got the low bitrate for the first second or so. You could see the pixelation in the LCD on playback.

    So can the GH2 finally shoot 1080p30 with the hack?

    How about defeatable AGC?

    Those 2 things are all I care about.

    It could always shoot 1080p @ 30 FPS slowed down to 80% speed. However, I don't think anything has changed at all with respect to frame rates. They are too busy working on getting the absolute highest bit rate without regard to whether it actually produces a visual benefit or not. I wish they would just leave well enough alone and start working on the frame rates instead.

    We are not working on "on getting the absolute highest bit rate without regard to whether it actually produces a visual benefit or not ".

    We are working on understandin encoder workings, improving 720p, improving stability, etc. Many things. And it actually produces visual difference.

    About frame rates. I spend big time on this with no significant progress. It is just too hard for now.

    @Vitaliy I have a few questions that could use your light.
    1. What is the best 1080p24 setting you were able to come across that is stable enough to work with a class 10 card? (Compression and GOP)
    2. What do the values mean for the AGC settings?

    AGC settings allow to adjust mic volume settings precisely.

    The only thing we have to do here is thank Vitaliy for his magnificent work. That's all. And wait patiently for new developments. BTW out of curiosity, any posibilities on Mjpeg 24p? Thanks again Vitaliy.
