How to increase JPG quality via autoexec.ash?

ye... lol just wondering....

So what's up with the new 1.2.6 ? testes yet ?
 
In photo mode, I hope
1. to limit the shutter speed not slower than 1/250 second and leave ISO auto. Or,
2. to definitely set the shutter speed to 1/250 second and leave ISO auto.
Could anyone write complete autoexec.ash scripts according to above problems?
My Yi Camera's firmware version is 1.2.0
btw.
Will the "autoexec.ash" hack method permanently work during a whole turing-on, even after switching from a photo/recorder mode?

Why 1/250??

Anyway, this the 2. (iso auto, shutter speed 1/252)
I don't know if the 1) is possible...

Not at all!

Another question:
In video mode, to reduce the movie shaking in a low light and maually held recording,
how could I set the shutter speed to 1/250s or so in a normal 1920x1080@30p format video?
Shutter speed=1/250s, but frame rate=30fps, I hope my question is not hard to understand.

btw.
Could Gopro Hero 4 basic editon use the autoexec.ash hack method?
 
"t ia2 -ae exp 100 0"
Why this command does not affect video recording?
 
How to set shutter speed for video recording, anyone knows?
 
Is there any ways to translate the exif value exposure time (1-2047) to fractional speed in seconds or viceversa?

sorry, there is no simple way for now. you have to test every custom ISO value for yourself one by one.

Thank you.
The script:
t ia2 -ae exp 100 0
or
t ia2 -ae exp 100 0 0
sets ISO 100 and shutter speed to auto.
Anyone can suggest a script to set ISO at a fixed value, shutter speed auto but with one or two stops over/under exposure?
 
Settings for capture in manual mode are kept in RTOSFS and override any changes done with autoexec script each time when you press the shutter button. So we can't change JPEG quality with the "t" command or with altering any memory bytes.
I'm trying to record 2s Time Lapse with 100% jpeg quality. I try t cal -jqlt 100 and writeb 0xC0BC205B 0x64, but there is no result, even the while loop does not produce images larger than ~4MB
I tried on two cameras
1. FW 1.5.12 HW 23L
2. FW 1.2.12 HW 22L

#Knee
t ia2 -adj autoknee 255
#ISO autoexposure gain
t ia2 -ae exp 100 Auto 0
#Auto WB off
t ia2 -awb off
#t cal -jqlt 100
#SET JPEG QUALITY TO 100
#writeb 0xC0BC205B 0x64
#noise reduction
t ia2 -adj tidx -1 0 -1
#disable sharpening
t is2 -shp mode 2
#file for sharpnes
t is2 -shp cor d:\coring.txt
#HDR 255 HDR, 1 High contrast
t ia2 -adj l_expo 191
#EV correction -1EV 64 -2EV 32
t ia2 -adj ae 96
sleep 10

while true
do
#t cal -jqlt 100
#SET JPEG QUALITY TO 100
writeb 0xC0BC205B 0x64
sleep 1
t app key shutter
sleep 1
done
