    My bitrates combination for AVCHD is 40xxxxxxx:20xxxxxxx:24xxxxxxx.
    And if you are able to review the pictures, I mean to avoid freezing the body when touching the Play button, make sure the first shot is a picture, not an AVCHD movie.

    As P frame size hits limitation, intraframe blocks compression became insane (3x-6x more size reduction). So, you have something like overcompressed I frame than P frame.
    Dont Panasonic know what they are doing?

    Mayor breakthrough coming. Stay tuned.

    As for Panasonic. No, they don't know. How they can make P frame size larger than I frame and have worse quality? This is kind of the hint to that's coming.

    PTool 3.35 released

    Limiting bitrate patch added. Now you can adjust AVCHD bitrate (with use of other three patches that we have already).

    Tested settings:

    Code:
    Video buffer                 - a) 33.500.000 b) 40.000.000
    Video bitrate adjustment     - a) 22.000.000 b) 32.000.000
    Overall bitrate adjustment   - a) 24.000.000 b) 35.000.000
    Limiting bitrate adjustment  - a) 26.000.000 b) 40.000.000
    a) Gives you 22Mbit bitrate with some spikes up to 24Mbit.
    b) Gives you 32Mbit bitrate with some spikes up to 34Mbit.

    For 720p60 actual bitrate can be slightly lower (I get 27Mbit at b) ).

    Top bitrate and best settings will be found by testers later.
    Possibility is it can be as high as MJPEG top bitrate for FullHD mode.

    Q: Such high bitrate clips are playable on camera?
    A: Yes, no problems during my limited testing. All plays fine.

    Adjustable bitrate AVCHD? Playback in camera? This is awesome news. Wish I was at home rather than at work so I could try this right now.

    I hope everyone who is so far benefiting from these updates is also donating .

    From my testing they can be used for profuction already.
    As for restrictions - testers will make it clear in uncoming days.
    We'll have patches with presets for AVCHD and MJPEG later.
