Hi All,
I am started using Yi just some week ago and want to tune it to have the best for what I need.
I wish to have good video for landscapes and areal photography with quadcopter, and also good quality 16MP stills with as less noise reduction as possible.
I did not find a way to disable noise reduction for stills.
I made test with RAW pictures set ISO to 100 and it still has lots of noise in it even at sunlight.
I link my RAW/JPG comparison result one picture is cloudy one is at direct sunlight:

(You have to download and zoom to 100% if checking quality and noise levels as opened in browser does not zoom to original resolution.)
Q: What do you think, is my Z23L focused close so to selfie too and I could improve far away object like landscape/trees sharpness by refocusing the lens
?
Let me share some sample video footage too:

(You have to download and zoom to 100% if checking quality and sharpness levels as opened in browser does only plays a reduced youtube quality 8mbps 1080p.)
I don't know why are videos shaking that much, I read reviews and when GoPro and Yi with same FOV and chip was on the same mount/grip the Yi videos were much more shaky.
This is the autoexec script I am using:
writeb 0xC06CC426 0x02
writew 0xC05C1EB2 0x41F0
t ia2 -adj ev 0 0 150 0 0 160 0
t ia2 -adj l_expo 163
t ia2 -3a 1 0 0 1
t ia2 -awb off
t ia2 -adj autoknee 255
t ia2 -adj gamma 180
t cal -sc 14
t ia2 -ae exp 100 0 0
sleep 10
t cal -jqlt 100
t app test debug_dump 14
sleep 9
t ia2 -adj tidx -1 1024 -1
My microSD's like only maximum of 30mbps (videos saved are about 31mbps by the way) so thats why it is set there.
I am not sure do I need the sleeps and is that millisec parameter?
Can I disable JPG noise reduction somehow?
I plan to change the lens to have less fisheye as I like zoomedin/tele lens, so ordered similar to this:
This is the most telephoto I found but too expensive for my project:
