whether Xiaomi Yi no stabilizer scripts?
I just wonder, what does the third parameter mean ?
Code:t ia2 -ae exp [ISO] [SPEED] [???]
Syntax:just read somewhere in topics - third parameter is digital gain
It can be 0 or 6 or 12 or 18
t ia2 -ae exp[iso|agc][-shutter_idx][mode] mode 0: ISO, mode 1: agc
t ia2 -ae exp 100 0 0
Syntax:
Code:t ia2 -ae exp[iso|agc][-shutter_idx][mode] mode 0: ISO, mode 1: agc
For example: ISO: 100, SHUTTER: Auto, MODE: ISO
Code:t ia2 -ae exp 100 0 0

Hey man thanks for the scripts, i'ts just what I was looking for, I wonder if you could point me in the right direction on how to add this to an excisting sript?Okay, i found it by myself. YI Can do shooting with fixed shutter and iso settings.
Try this script at 2.3k (or 2.5k) 24\30fps to get better result
Line runs fixed "1\30" shutter with fixed "ISO100" with "0" dgain.
These lines work on my YI Z22 with 1.2.10 firmware without any problems:
t ia2 -ae off
t cal -me 0 448 1012 0 0
t ia2 -adj tidx -1 100 -1
this will work for any FPS, but need modifications to reach some high-fps settings (60fps or higher!).
Manual shutter speed sets like in photo mode "1-2047", but should be "1012-2047".
Iris set to 0, because we don't having changeable apeture on action camera.
Explanation of numbers:
The command syntax is:
#t cal -me [mode 0\1][agc][shutter][iris][dgain]
Mode can be 0\1: 0 - for Video, 1 - for Photo
AGC - use these numbers to get needed fixed ISO:
ISO100: 448 ISO200: 384 ISO400: 320
ISO800: 256 ISO1600: 192 ISO3200: 192
IRIS - always should stay 0
Dgain - boost light and colors, can be
0 or 4096 or 8192
The bigger number - the more light and also colored noise will be in final image.
Tried with 60fps, works normal (not changing iso and shutter in bright or dark conditions)
Footage looks blurry while moving\rotating camera, it's cool for cinematic purposes.
also you can add
t ia2 -adj l_expo 50
while shooting low iso (100-400), to get crispy image.

How do I know the shutter speed in a video?
I am greatly surprised on how well this little camera can perform with the lens being in focus , with an IR lens and high bitrate . Upon further trying to improve video quality , I observed that there is heavy motion blur in videos. Is there a firmware entry to tweak shutter speeds in a video ...dashcamtalk.comHow To: manual exposure in video mode
While my friend needs to use 6~7 YiCams to shoot VR aka 360-degree video, and facing the issue that different angle will have different exposure value. And I've done many many testing, now finally get the solution for setting manual exposure in video mode. pls use the following steps to test by...dashcamtalk.com
UPDATE2:
attached zip-archive for different ISO 100\3200 and shutter speed 1\30-1\100
Hey man thanks for the scripts, i'ts just what I was looking for, I wonder if you could point me in the right direction on how to add this to an excisting sript?
And do you know to what I need to change the shutter speed value for 1/48s?
Have a good day!
