    At this point in time the firmware was tested Russian users.
    It will be two versions of the firmware: standard and protune.
    The second firmware is better suited for postprocessing because
    digital filters are disabled intracameral video processing.
    The original test video can be downloaded in the description to the movies...

    that sounds awesome. any idea when you will release it? :)
    will it be compatible with H8 Plus?

    I could imagine adding a better lens like on the yi- and we have a pretty awesome camera.
    Can you get the bitrate higher, too?

    In the dark, it's better to shoot in 2.7K.
    In bright lighting, the picture is better in 4K.
    In the dark time between 1080p and 1440p there is no difference...

    I see. did you increase the bitrates for your mod?

    Is that already maximum or can it go higher?
    still lots of artifacts at 50 mbits stock firmware.

    Above 50Mbit I did not try. Artifacts disappear after 30Mbit.
    This depends on the intra-cameral processing with digital filters.
    For example, in 1080p 120fps mode, no bitrate will help.
    Even if you put 100Mbit in the settings ...

    You can set the ISO range:
    1.jpg ISO800...400.jpg
    These parameters work for video mode.
    The maximum ISO value in the original firmware is 800 units.
    I limited the value to 100, 400 and 3200 units as an experiment.
    In passing, I want to cancel the duplication of frames with reduced lighting.
    You can also lock the AUTOKNEE and EXPO parameters.

    Now I'm just experimenting in this direction ...

    Looking very nice!
    Hope you can release it sometime soon! :)
    configuration of ISO is of course done in firmware directly?

    Hello
    I have done Eken H8 Pro external power mod for DVR use. I've soldered li-ion charger TP4056 to battery cell and now camera can works all the time from car USB charger or power bank.

    https://image.ibb.co/gozwRF/DSC_2804.jpg
    https://image.ibb.co/cF1AmF/DSC_2801.jpg
    And i discovered that my toshiba 128gb memory card works in 4k30 resolution only when is formatted as fat32 and 64kb claster size (in exfat file system it records only 2 minutes and after that stops recording).
    I removed front LCD display and now camera power consumption decreased by 30% also it less heating.
    Also my camera was broken it freeze all time, recorded artifacts, and sometimes turn on only front display
    i fixed it by change smd resistor, old had 195k ohm new 200k (exactly model SMD 200K ohms 1% 0402). This resistor in red circle https://image.ibb.co/hL14Dv/DSC_2800.jpg
