Yi hacked resolution 2304x1296 30fps 35Mbits

Thanks! I am going to try it out.
 
It doesn't work. When I flash the firmware, I cannot access the settings page on the Yi app (android). Flashing back to another FW fixed it.
 
hello, what setting should you touch in the autoexec.ash file to have more bright colors or pastel?
 
Is their any firmware that lets you use the extra sensor data at the top and bottom of the picture. (Like GoPro superview)

You can try this attached script. The script stretches 1600x1200 60fps(4:3) to 1920x1080(16:9). I don't know if we lose any resolution by doing this.

My preference is to get the 1600x1200 60fps at max bit rate, so I can process it outside the camera.

...it works :)
adresses for "writel" values?
"writel" is for changing resolution after recording, can you explain?
 
Yes, it changes only the ouput(mp4) resolution.
You can edit it put any resolution you want there:

writel 0xC05C2D7C 0x04380780

convert from hex
0x0438 = 1080
0x0780 = 1920

this is only an edited 1600x1200 60 mode(0x0c). You have to have the cam in that mode first or it will not work. The resolution table starts at address C05C2C8C in 1.2.13 fw.
 
thankx @funnel,
this code would be upscaling from 1280x960 60fps 35mbits 4:3 into 16:9 0f 1080p
Code:
#superview2
#for YI firmware 1.2.13
#stretch 1280x960 60fps to 1920x1080
writeb 0xC06CC426 0x16
writel 0xC05C2D7C 0x04380780
#set bitrate 1280x960 60fps 35 Mbps
writew 0xC05C2272 0x420C

Hey Gente, do you know if 1600x1200 @60fps is upscaled too?

What is the script for obtaining 1600x1200@60?

Thanks

...normaly no resolution set by script is upscaled.
To become superview ( bigger foto cut) picture like gopro make, you have to record with 4:3 and than upscale to 16:9 via camera(script) or with software. Thats the only reason for upscaling.
In the @funnel superview.zip you can read the adress you need for 1600x1200@60.
the line with "writeb....."

Thanks for the info!

Ignoring superview, because I don't need to bring it back to 1920x1080.

I think 1920x1080@60fps is an upscale/interpolation from 1536x1152@60

So I'm wonidering if 1600x1200@60 is also an upscale from 1536x1152@60

Or would 1600x1200@60 be a native resolution of the Yi because you are using more of the sensor when you record in a 4:3 format.
 
Funnel, thanks for your script. I like that field of view! But I have some problems, my videos are short and bitrate is nonconstans . MicroSD is OK. Has anyone similar problem?

My guess is MicroSD in probably NOT OK.
 
I made some films today and now is good. :) we will see how it will be in future.
 
It's possible that stretched 1280x960 60fps to 1920x1080 has better quality than stretched 1600x1200 60fps to 1920x1080?? I'm obtaining better results with the first one...
 
Please share your script for stretched 960p->1080p, I will make some test.
 
Here in thread some posts back i shared the script...
edit: sorry it doesn't work because i need another code for:
writel 0xC05C2D7C
