Something is wrong with the colors. Too much saturation? Or terrible CA? Or some artistic filter applied in post processing?
Very strong vignetting in corners too. Is this photio taken with the casing on or off?
I use a different lens, so chromatic aberration is on the video.
In the future I will correct the aberration correction profile. I left the color correction for later.
The priority is to reduce excessive sharpness and excessive contrast with the level of black.
May I ask what the intention of this thread is? Is it to promote a costum firmware.
If so it would be great to write the benefits down (as a list of key features) because the transcoding that happens during the Youtube upload does not allow to illustrate improvements very well.
The purpose of this topic is that ordinary users can use alternative software to get the maximum result.
Yes, but what are the improved aspects?
- photo or video?
- qality or stability?
- cetrain resolutions and framerates, or all?
-reduction of excessive sharpness
-correction of gamma curves
-correction of black level
-correction of GOP parameters
-correction of metering tables
-correction parameters AGC
-correction of sharpness parameters

How does this firmware compare to the firmware from goprawn?
I used the firmware listed on goprawn. See this sample of the results.
At 36 MHz, the results are far better than the SJCam firmware. But...it's inferior to my Sony FDR-X3000 delivering 40 MHz (IIRC 42 MHz).
The SJ8 has the guts to work at better than 36 MHz. Why does it take a hacker, instead of SJCam, to deliver at least 36 MHz? [/ head scratch]
SJCam SJ8 PRO - MOD#4.3 (1080-60 EIS ON)
SJCam SJ8 PRO - MOD#4.3 (4K)
60 Mb/s? Wow! I agree that the colors seem to be over-saturated. But that may be a user choice, not a firmware flaw. But...where, where, where can I get MOD4.3??? I don't see it in the thread on Goprawn. Searching yields hits on "MOD", "MOD4.1", etc., but no MOD4.3.
From Google Translate:
60 Мб / с? Вот Это Да! Я согласен, что цвета кажутся перенасыщенными. Но это может быть выбор пользователя, а не недостаток прошивки. Но ... где, где, где я могу получить MOD4.3 ??? Я не вижу этого в теме на Goprawn. Поиск приводит к попаданиям по "MOD", "MOD4.1" и т. Д., Но без MOD4.3.
Utility for changing the bitrate by itself...

What do the two boxed columns mean?
GOP on wiki.
I would probably make a ass of myself trying to explain it.
Looking promising. How did the camera handle the heat?
I think it will be okay in a outside situation like that, as opposed to a tropical location with 0 wind and 40 degrees + direct sun on the camera..
I tried my Osmo action a few days ago in the living room ( about 20 deg C room temperature ) windowsill as a thunderstorm passed over in the evening, the OA shut down due to heat after around 30 minutes of recording 4K/60.
But i did another recording yesterday outside with the camera on a tripod also in the evening, and then the OA did not do a thermal shutdown.
It is action cameras so you film in shorter bursts, and / or you have some degree of cooling from the wind
I'd just have to go somewhere and lie down for a while...
Seriously, this is one of those places that requires in-depth knowledge to avoid calamity, if not disaster
