    Hello Guys'

    Testing audio change:

    Audio bufer: 14.500.000
    Audio encoding bps: 1280000
    Audio sampling rate: 48000

    Can't working (camera freezing).

    Audio bufer: 14.500.000
    Audio encoding bps: 576000
    Audio sampling rate: 48000

    Can't working (camera show message about card speed)

    Audio bufer: 6.000.000
    Audio encoding bps: 320000
    Audio sampling rate: 48000

    Working well

    Audio bufer: 8.500.000
    Audio encoding bps: 320000
    Audio sampling rate: 48000

    Working well

    Audio bufer: 11.500.000
    Audio encoding bps: 320000
    Audio sampling rate: 48000

    Working well

    Audio bufer: 14.500.000
    Audio encoding bps: 320000
    Audio sampling rate: 48000

    Working well

      Yes pure 1080 24p. Downloaded Car3o clip and transcoded. worked and looks good! this almost makes me want the GH1 even more now that there isnt a pulldown removal step.

        Try to test sampling rate instead.
        It seems that AC-3 have limit around standard top rate - 448kbps-640kbps.
        But we need to try to change sampling to 96000 and double audio buffer size. Most probably it won't work.
        I'll try to change sampling patch again soon in this case.

          Okey I will testing it.

          Interesting fact: Bitrate adjustment 3 (can't be more 20.000.000).

          Testing audio again ;-)

            Too can't working (camera freezing).

              Thanks for useful testing, results as expected.
              I'll add more encoding rates to find barrier precisely.
              And modify sampling patch.
              Useful could be also to test 44100 and 32000 sampling rates after I'll add them to selection. We need to understand if this is AC-3 encoder problems or PCM audio problem before encoder.

                I'll be waiting ;)

                      What does "original frame rate" mean ? Why is it always double the actual framerate ?

                        It is some MediaInfo term. Normally it shows some strange values :-)

                          PTool 3.28 released.
                          MJPEG Settings patch added.
                          AVCHD compression patch added.
                          Audio sampling rate patch changed.
                          Audio encoding rate patch adjusted.

                          Special notes to testers:
                          1) We need to find possible top bitrate for AC-3 encoding.
                          2) Sampling rate also must be tested starting from 32.000 up to 192.000.
                          3) MJPEG Settings requires test not only 1280x720, but other resolutions also.
                          4) AVCHD compression must be tested in FullHD and SH modes. Check if it reduces birtrate.

                            He should have it very soon. Maybe today or tomorrow. It's pass customs. We should also have a Gf1 for tester as well.

                              Parcel stuck somewhere, as our postage is complete nightmare last year.
                              I hope to get it next week.
