Yi hacked resolution 2304x1296 30fps 35Mbits

[funnel]

Can someone please explain me
How can I setup the bitrae above 12mbps in 1600x1200 60fps mode.
It looks like any code i'm using for bit rate only give me the 12mbps.
this is the script I costum:

#set video resolution to 1600x1200 30fps
writeb 0xC06CE446 0x0d

#set bitrate to 25Mb/s
#writew 0xC05C1006 0x41C8
#set bitrate to 35Mb/s
#writew 0xC05C3046 ox420C
#or
writew 0xC05C3016 0x420C
#set bitrate to highest for 1600x1200
#writew 0xC05C31F6 ox4170

thank you all

#bitrate for firmware 1.2.10
#set video resolution to 1600x1200 30fps
writeb 0xC06CE446 0x0d

#set bitrate to 25Mb/s
writew 0xC05C3226 0x41C8

Should work. Didn't try.

Please 2304x1296 30fps 35Mbps for 1.2.10-fw?

 

[huhu1030]

I checked the bitrate table,
#set video resolution to 2304x1296 30fps
writeb 0xC06CE446 0x02

#set bitrate to 30Mb/s
writew 0xC05C3016 0x41F0

Is this correct ? because my camera act very weird when I put the auto exec.ash to the card I immediately removed it.

 

[Yochai Hillel]

Thank you very much dear #funnel for your quick answer
Yes, It's work

Could you please explain me from where did you take this setting combination?

1. why did you use this setting 0x41C8 from this line 9 1920 1080 59.94 41C8 C05C3046

2. Can I use a higher bitrate with 1600x1200 60fps?

3. what is the highest bitrate on 30fps 1600x1200?

Thank you for answaring even part of the Q's
Best Regards

@funnel can you figure out how to hack the timelapse_video_resolution

{"video_resolution": "2304x1296 30P 16:9"},
{"timelapse_video_resolution": "1920x1080 60P 16:9"}

Updated: I tried to readb start from 0xC06CE446:

readb 0xC06CE446 > d:/address.txt
readb 0xC06CE447 >> d:/address.txt
...
readb 0xC06CE4D9 >> d:/address.txt
...

finally found the address of timelapse_video_resolution should be: 0xC06CE4D9 !

{"timelapse_video_resolution": "1920x1080 60P 16:9"}
0xC06CE4D9 = 0x03
{"timelapse_video_resolution": "1280x960 60P 4:3"}
0xC06CE4D9 = 0x16
{"timelapse_video_resolution": "2304x1296 30P 16:9"}
0xC06CE4D9 = 0x02

tested with autoexec.ash success:

# timelapse video resolution 1296p
writeb 0xC06CE4D9 0x02

# bitrate 35Mbps (the same)
writew 0xC05C3016 0x420C

 

[funnel]

@luckylz
Here I have the an entire spreadsheet of preferences and quick description of what they do.

 

[luckylz]

great sharing, but it seems 0xC06CE4D9 just out of the list

 

[schnurbi]

@funnel:
how do we use these preferences?
can we change the startup mode of the Yi (starting in video/photo mode) via this script?

 

[danistuta]

Is there a script for use 2k resolution 35mb with 1.2.10 firmware? Possible to integrate in ymax-movie script 1.2.10?
Thanks a lot.

 

[Flythai]

After i read the entire topic i found this script, this is what i need with some modifications, i have 1.2.10 firmware and 23L version,
I no need the 2304x1296 video res, i only work with 1920:1080 50p and 1920:1080 25p, and thats it, if you guys can help ?

#set video resolution to 2304x1296 30fps
writeb 0xC06CE446 0x02

#set bitrate to 30Mb/s
writew 0xC05C1006 0x41F0

#set noise reduction value to 2048
t ia2 -adj tidx -1 8192 -1

 

[huhu1030]

#set video resolution to 2304x1296 30fps
writeb 0xC06CE446 0x02

#set bitrate to 35Mb/s
writew 0xC05C3016 0x420C

This put res to 2304x1296 30fps @35mbps
Tested and I confirm that it works

Can someone confirm me, noice reduction line is still the same for the latest firm:
t ia2 -adj tidx -1 2048 -1

I'm newbie...how to load autoexec.ash? Is there something to modify in my camera? Thanks.

 

[Squeamish]

To load the autoexec.ash fie, copy it to the root level (not in any folder) of a microSD card you intend to use in the camera. When the camera starts, it reads the script and executes the commands it contains. Changes are temporary for the session in use, not permanent.
Nothing to change in the camera.
Read post #60 in the following thread:
https://dashcamtalk.com/forum/threads/xiaomi-yi-share-your-scripts-and-settings.12707/page-3

 

[danistuta]

Ok, thanks...possible to have a bitrate higher than 30mbit in 2k?
Thanks again.

 

[Squeamish]

See post #491, above. 35Mbps works, but, after the first recording, the bitrate begins to decline, going lower with each succeeding recording. I don't know why or how to fix that.

 

[Flythai]

I Squeamish, do you know how i set the script for 1920:1080 50p and 1920:1080 25p and 30Mbps ?
Thanks

This script work for me in 2k:

#YiMAX-movie script by nutsey for 1.2.10 firmware
#This script is for video mode!
t ia2 -adj ev 10 0 60 0 0 140 0
#shadow/highlight clipping adjustments

#set gamma level
t ia2 -adj gamma 220
#enable 1296p30@30Mbps video
writeb 0xC06CE446 0x02
writew 0xC05C3016 0x41F0

I tried to delete this lines to avoid raw photos, but script the doesn't work, why?
#enable raw+jpeg stills
t app test debug_dump 14
sleep 9

How to set only jpg to the 100% best quality? Thanks.

 

[Squeamish]

I Squeamish, do you know how i set the script for 1920:1080 50p and 1920:1080 25p and 30Mbps ?
Thanks

Sorry, no I don't. Maybe try a search using those terms. I think I remember seeing some recent conversation from Schnurbi about that, but can't find it now.

Ok, thanks, im still searching

That should do the job...
Any part of a script not working will cause the entire script to fail.
Essential conditions for using autoexec.ash files:

- File names other than autoexec.ash don't work.
- Line endings in the script must be Unix style. Improper text editing is the most common reason for scripts that don't work.
- The last line in the script must be a blank line.​

#Set jpg Quality to 100
writeb 0xC0BC205B 0x64​

That seems to be working OK, but didn't verify that it is. You'd have to compare results in different firmware versions to have a better idea. Not worth the effort to me.
