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?

[nutsey]

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

Is it V01 or V02 version?

[nutsey]

How to determine it?

[czaroslaw]

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-

[nutsey]

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

[czaroslaw]

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?
