Yi hacked resolution 2304x1296 30fps 35Mbits

[VIIVIIIXIII]

Can anyone compare SJCAM SJ4000 (1080p 30fps) vs Xiaomi Yi (1296p 30fps 35mbps)? I wasn't too impressed when i compared the stock xiaomi video (1080p 60fps) with SJCAM SJ4000 but now I'm curious to see if this mod makes it better.

can someone tell me, if I got it correct.. you use custom FW also ? or I got it wrong ? if so, why ? what is different than using scripts ?

flat picture look

Thanks to all for the work on this camera and for sharing your settings. What's the script for flat picture? thanks

 

[Doomboy]

Im all so looking for that flat picture in video. Would love to set sharpness, saturation and contrast. Havent seen a script on github for that but some people talk about it

 

[fuyghjb]

avent seen a script on github for that but some people talk about it

Make your wn script

Thanks. Must have missed that post.

What is a flat picture?
In photographic profession, a flat picture is one that lacks contrast,

 

[bosiwow]

Yeah, I was thinking the same but YiMax does the following according to the website:
" Adds colors and details in shadows and highlights. Reduces noise filter. Enables RAW+JPEG capture for stills "
But maybe the addition of color is only in movie mode ?

But maybe the addition of color is only in movie mode ?

It affects both photo and video modes.

 

[bosiwow]

Schnurbi told me YiMax gives you flat video and that I would need postprocessing to get the colors back. But the script states it adds colors, I don't understand that :s
And what does that "14 scene mode" do :/
I would really love if somebody could explain all these settings:

#YiMAX script by nutsey for 1.2.0 firmware
#vibrance/saturation adjustments
t ia2 -adj ev 0 0 140 0 0 150 0
#shadow/highlight clipping adjustments
t ia2 -adj l_expo 163
t ia2 -adj autoknee 255
#set gamma level
t ia2 -adj gamma 220
#enable 14 scene mode
t cal -sc 14
#enable raw+jpeg stills (I understand this setting )
t app test debug_dump 14
#set noise reduction value to 1024
t ia2 -adj tidx -1 1024 -1

This doesn't seem to work on my Yi camera. I have the latest firmware I believe 1.2.6. Once I copy over the autoexec.ash to the root of the micro sd card nothing happens. There are no new options within the android app, no resolutions or bitrates when I try that file.

Any ideas? Maybe it's incompatible with 1.2.6?

 

[Ghetto]

The idea is read all posts before ask something in a forum... all your problems are solved too many times...

The autoexec.ash file must have Unix line endings to work. That's the most common mistake. It has been mentioned in these threads many, many times. You just need to use a proper text editor.

Hi everyone,
I'd first like to say a massive thank you to all those involved in compiling this stuff. I have read through every page on this discussion and I am completely blown away by the level of understanding you guys have, but more importantly the fact you are helping random people from around the world for absolutely no personal gain.
I've downloaded Sublime Text 2 as suggested by Squeamish for my Mac and had a peek at the wizardry within. I do not have a single clue about what the writing process for the scripts mean, all I can gather is there are lines of code that reference certain settings and the camera uses those on boot up. Well done on finding this info!
Like I said, I've read every page, and I'm reasonably confident I have found the right settings I would like to use on my Yi when it arrives next week. I'll update it via the manufacturers recommendations, then load the autoexec file into the root as you guys have suggested.
The files I will use are here (my dropbox), hopefully this will give me sharp footage (no excessive noise reduction) in 2k at 30 fps with a bitrate that will be sufficient, and not damage / overheat anything.
I know you guys must be busy with skills like this, but if you have a sec to double check the code is right for what I need, I would really appreciate it.

Once again, THANK YOU to all involved!

Hey at all,

i want to combine two or 3 scripts....i tried to copy the text from the one .ash file into the other, and copy the file to the sd root... but it didn't worked...
i'm new here, sorry -.-

 

[Tokra]

show us what you wanted to do and what you did.. maybe someone can help

i want to shoot videos in 2k (now it works with the YIMAX-Movie-Script from here: http://nutseynuts.blogspot.de/2015/06/xiaomi-yi-action-cam-custom-scripts.html )

when i would like to combine this script with another script for RAW- capture in example, i have to copy the line from the script into the Yimax Script?
like this?:
#YiMAX-movie script by nutsey for 1.2.0/1.2.6 firmware
#This script is for video mode!
#t ia2 -adj ev 10 0 60 0 0 140 0
#shadow/highlight clipping adjustments
t ia2 -adj l_expo 163
t ia2 -adj autoknee 255
#set gamma level
t ia2 -adj gamma 220
#enable 1296p30@30Mbps video
writeb 0xC06CE446 0x02
writew 0xC05C1006 0x41F0
#enable raw+jpeg stills
t app test debug_dump 14
sleep 9
#load GoPrawn config
t cal -ituner load d:\goprawn.config
sleep 1
#fix ae/awb/adj locks
t ia2 -3a 1 1 0 1
#ready beep
t pwm 1 enable
sleep 1
t pwm 1 disable

>>>lines from another script:

#RAW WB + IMPROVED HIGHLIGHTS script by nutsey
t ia2 -3a 1 0 0 1
t ia2 -awb off
t ia2 -adj autoknee 255

Can i put this togehter in one? or any other scripts?
does one file work for video an photo mode?
