Yi hacked resolution 2304x1296 30fps 35Mbits

the script do give 35 bitrte, but the image quality is bad. First picture is without script and the other is with.
They are both screen capture from the video.

ok only for you script only resolution setting 1296p 30fps 35mbits,4GB splitting and ready beep without other lines for sharpness, exposure....

thanks for the scripts guys i got a full edit done


Any other tips for better footage ?

i might play with some of the things i seen in the script posted on this page for sharpness, saturation, vibrance, exposure , gamma and see how that looks
 
Ty ill try it. if i want 1080p with 60 fps and 35+ bitrate.. Both of the bitrates will work at the same ash file? Or for every resolution i need separate ash file?
 
both work but not together, you need only set an hashtack(#) before that lines of resollution settings in script you don't want to start.
And remove hashtack from that resolution lines you want cam to start with. Use an editor like notepad++. I have posted here in nr.646 a text file howto use autoexec.

This is my approach to as immersive footage as possible. Recorded at 1600x1200 60p with lens rectification off(!). Then rectified, cropped and resized to 1920x1080 without losing the horizontal field of view with perfectly straight-lined image. This is different of the superview idea presented here - to stretch 4:3 footage to 16:9. I like to have correct proportions of the image which my way does 😉.

autoexec.ash
Code: 
#mode 1600x1200
writeb 0xC06CC426 0x0C
#mode 0x0C resolution set to 1600x1200
writel 0xC05C2D7C 0x04B00640
#set bitrate 30 Mbps
writew 0xC05C2092 0x41F0

#set noise reduction value to 50
t ia2 -adj tidx -1 50 -1
sleep 1

#ready beep

Hi ondrascz, and welcome to the forum 🙂 I like the video, thanks for sharing. I'm downloading virtualdub and filters now, and will probably give it a try later.
 
Hi guys, and possibly @funnel 🙂

I'm on firmware 1.2.13 on XiaoYi 23A, and looking at your bitrates have this in my autoexec:
Code: 
writew 0xC05C1EB2 0x420C
writel 0xC05C2CB4 0x05A00A00

It basically takes the addresses for 2304x1296 30P 16:9 and sets:
Bitrate = 35Mbps
Resolution = 2560x1440

So, I'm getting 2560x1440 @ 35Mbps files on my Xiaomi Yi.

My question is: Are those videos only upscaled from 2304x1296, or are they actually filmed in that resolution?
EDIT: And another question, if it's only upscaled, is there a way of enabling natively 2560x1440? I'm aware that the app might crash, I couldn't find answers on search

...i mean the 2506x1440 are upscaled after recording.
I als0 have no chance to set that resolution via script, i tested many times.
Code: 
2560x1440 30fps to 50 mbps
#writeb 0xC06CC426 0x00
#writew 0xC05C1E52 0x4248

And how to turn on the resolution on the App ? I have version 2.1.1. on my phone , so I can select it as a resolution for recording?

As far as I'm aware there is no way to set it via the App, I'm effectively setting it in autoexec.ash to overwrite those values for 2304x1296 @30fps, so the videos I get are 2560x1440, 35Mbps @30fps, but not sure if upscaled or real.

I could speculate that the resolutions are hardcoded in the app, or maybe the app is getting them somewhere from the firmware (although unlikely)

...only setting via script, but the script crashes while booting...

@gente What does this line mean?
Code: 
#writeb 0xC06CC426 0x00
Where is that address from?

@blacki2015 If you put the two lines from my post in your autoexec.ash, and have 2304x1296 @30fps @High quality set into the App, the resulting videos should be 2560x1440 @35Mbps
Just be careful of the firmware version and the hardware version, and make sure to have a newline at the end of your autoexec.ash

Not quite.
The "#" sign means comment, if you write stuff without it that makes no sense to the camera, it will crash.
For example, do this:
0. Make sure you're running 1.2.13
1. From the app, select the highest setting on video mode, 2304x1296 @30fps.
2. In settings, make sure it's set on Video Quality: High
3. For safe measure, make the camera start in Video Mode
4. Download a pre-existing autoexec.ash or make your own. Just make sure you know what you're doing with the newline. Use Notepad++ for safe results. Bottomline, make sure that you know how to write an autoexec.ash file that actually works.
5. Put autoexec.ash in the root of your SD card.
6. Put these two lines at the beginning of the file:
Code: 
writew 0xC05C1EB2 0x420C
writel 0xC05C2CB4 0x05A00A00
... this will give you 2560x1440 @35Mbps
If you want 50Mbps, replace the first line with:
Code: 
writew 0xC05C1EB2 0x4248

The first line overwrites bitrate for selected resolution (in this case 2304x1296)
The second line overwrites the resolution value, turning 2304x1296 in 2560x1440, but I'm not sure if upscaled or real.
More info here:
https://github.com/PJanisio/Xiaomi_Yi_autoexec/tree/master/bitrate/1.2.13

EDIT: 50Mbps can be dangerous, it can heat up the camera quite a lot, and have crappy results if you have a lower class SD card

Nice effect @ondrascz could you please explain more detailed virtualdub process for those like me who are not use to it, with a video or even screenshots... no rush obviously.. 🙂
