  • "Varigop" setting for the GH1, features:
    • Excellent IQ in AVCHD 1920x1080p 24fps (3GOP)
    • in-camera playback (AVCHD files) is possible
    • absolutely reliable spanning as long as battery lasts / until end of memory space of the SD card (max 32GB)
    • integrated timelapse function in MJPEG (By Jordan Noblet)
    • Usage of all camera working modes (A, S, M)
    • Usage of all lenses, legacy Panasonic lenses as well as vintage ones
    • highest achievable bitrates on the GH1 and very high average recording bitrates in NTSC (considerably lower in PAL)
    • top reliability and in-camera-playback for most of the files

    • NTSC:
    AVCHD FHD = 1080p24 3GOP superb detail in highlights and shadows / smooth looking motions / very high bitrates / spanning works very reliable
    AVCHD SH = 720p60 3GOP with even higher bitrates (bitrates about 10% higher than in 1080p24) / IQ looks good, needs more testing as this mode was not primar target of the patch

    PAL:
    AVCHD FHD = 1080p25 13GOP looks good, needs more testing (bitrates about 60% of 1080p24)
    AVCHD SH = 720p50 26GOP looks good, needs more testing (bitrates about 40% of 1080p24)

    MJPEG (both in PAL and NTSC):
    Integrated timelapse settings by Jordan Noblet / 2fps in "HD" 1920x1080 / colors 4:2:2 / It is ideal to use 1/2s exposure to get beautifully looking subject's motions in the blending frames, so strong ND filters are necessary in the daylight. Of course, shorter exposures are also possible- with sharper looking motions. In 2fps mode maximal file size (in MJPEG not avoidable) will be achieved after ca 1h25m. One can stop-and-start again the recording for longer recordings and edit later. For rendering is recommended to use Jordan Noblet's free software, you can download it on his website http://www.timelapser.net
    All other MJPEG modes (WXGA, XGA, VGA) are also influented by the 2fps setting in HD mode, so rather forget them. File format after rendering in "Timelapser": AVI 1920x1080p 25fps

    Bugs reports:
    The released beta version of the "Varigop" runs in many situations stable, but it is regularly freezing if the object is well-lit grass or trees. All users of this setting should please keep me informed about observed bugs and feel free to post directly here. All those information will be very helpful for the development of the setting until the stage when "alpha" version can be released some day.

    If you use this patch and like it, please don't forget who made all this with his tireless work possible and make donation to Vitaliy on the top of this page and support that way his hacking projects.

    (beta-version released on January 30th, 2013)
