    Thank you I will try it! Is is possible to change saturation and contrast? I can do it myself but what to search in hex editor?

    Спасибо! А возможно ли как-то поменять насыщенность и контраст (по-меньше сделать)? Я могу и сам сделать, но я не знаю что искать в коде?

      Можно. Поделитесь образцом видео или стоп кадром для понимания задачи.

      Firmware version gives such information. It is composed of date and version. The difference is in lcd screen and its driver.

      The newest firmware for old lcd type is N20150409V01: http://support.sjcam.com/support/sol...creen-non-wifi
      The newest firmware for new lcd type is SJCAM_SJ4000_Firmware_v1.7 (I'm not sure if there is V02 in firmware version): http://support.sjcam.com/support/sol...ewest-version-

      I believe it's for V01. But please make sure to have a flash memory dump before trying.

      Yes it is for old type screen V01
      Inside firmware I've found its version: N20140929V01

      There is newer version in link above.

      Could You give addresses where max iso value and bitrate table are stored? And how they are coded?

    Я имел ввиду поправить в firmware? Сделать процентов на 10 слабее и контрастность и насыщенность? Что в hex-редакторе искать?
