Xiaomi Yi Custom firmware with lastest revision

Hi, how's the battery with this custom firmware because i get less than 40 min of rec with official firmwares. I'm paragliding and when i stop recording I leave the camera in stand-by (i've sett it to 3min). Is this the cause of the battery drain?
Thanks! and sorry if it had been asked before.

what's the temperature like when you're paragliding, cooler temps can shorten battery run time
 
It's not so cold, as long as i feel comfortable. I think the main problem is stand-by. I will power it off after recording to see if i get more battery life
 
Ela! Ti kaneis??!?! Yi sports is the Xiaomi Yi. Its one of the new batches with the 1.3 firmware and Z25L serial number.
 
Is this best custom firmware to install for newbies ? 😀

In first post I read that this firmware is ONLY affecting High quality mode, so it means that when I take videos in medium quality I will have standard firmware bitrates?
 
Dear Fried.,

I have an 23L Yi and I want to make a firmware which is take the whole image processing zero ( noise reduction, distortion correction, gamma, gain ect... all of it go to zero)
Do you think it can be possible with a firmware mod or just using a script?

I want to get the original unchanged and the best quality pictur from the Yi.

And an other question, is it possible to make Bulb exposition in photo mode?

I want to make a housing for the Yi that cool the CMOS and hold C-Mount lenses, and after it is finished, I want the best original processing-less image from it.

What do you think?

best regards
Adam.

I creating this new thread, because in the other one it's becoming a little messy doing a firmware for everyone. I'll try to keep it up to date.
In here you'll find only two type of firmware, because are the same for different build of camera.
You can check md5 on your own to be sure about that.

Both of firmware are customized to get 35Mbps for every resolution in High Quality mode.
Medium and low quality are untouched.

Before flash rename it "firmware.bin" and copy in the root of microSD card.

Because is not a secret how to customize bitrates in a firmware I'll add the video that explain really well how to do it, and who want to try could do it ... 🙂



Enjoy...! 😉

Hi guys,
I have a strange problem with my camera.
When I start recording it's recording @31mbps 10sec then stop and continue with 21mbps. The files are separated in two. The first one with 31mbps 10sec and the second with 21mpbs. Both in 2K@30fps.
I've never faced this kind of problem so i dont know what to do. Maybe flash the firmware again ?
 
This problem was discussed in this thread a 100 times, you just have to go some pages back to find out, probably slow SD card or... something describet b4...
 
I've always used custom firmware with higher bitrate and i've never faced that kind of problem. It's probably not a SD card issue cause it's a Sandisk Ultra class 10 which supposed to be fast.
But i'm gonna saerch through the previous pages thanks.

Maybe not the best, but most balanced.. yes if you shoot in any other quality you'll have stock bitrate..

You can change these setting via script, if you need a flat image to postproduce take a look at nutsey script search about it... For bulb shoot I don't think so, you can set a loooong time but not bulb... for housing there's a good one in aluminum that not cover mic and protect lense..

This is a very strange issue cause I use a chinese 32gb card and I never had this problem others have to buy expensive card to make it work, in theory as other already said it's speed problem..
 
Thanks Fried, can you give me recommendation which other custom firmware i could try for better video quality?

take a look in first pages of this thread, other users made other custom firmwares... 😉
 
@ovu

Not to hijack the thread, but since you put it here... if you can afford another 6-12oz on the frame, I would highly suggest buying or building a 'tank' battery. 0:45 running 2k/1296@30 or 1080/60 is all you can expect from these little things! This little on-board 990-1010mA battery? C = xT so, that's roughly a 24mA drain to get 0:41 runtime... that's incredible! But, being on a glider, you probably don't want to try to do a battery swap. 🙂 Get one made from 3 or 6 18650 cells, same cells that laptop packs are made from, 3 in series with an efficient voltage booster circuit can easily top 10,000mA, which should be 10x the runtime of the on-board battery, and 6... well that's all day recording right there.

additional Xiaomi Yi batteries, current version 1010Ma, $5.59

a Xiaomi tank battery, 10,000mA, $16.99

a Xiaomi massive 20,000mA tank battery, $31.99
(I love this one, 6 cells, weighs 12oz, charges fast, lasts forever)

note: I get nothing from BangGood, just a satisfied customer who's sick of dealing with DX.
 
As someone who has intentionally over-driven slow MicroSDXC cards for hours, that is not the behaviour. The only thing I've ever seen, even @ 50mbit, is they just drop frames, you'll get 'dead spots' every second or so, the length of which depending on just how slow the card is... it has never stopped the recording and switched to a different bitrate, huhu! That's something else entirely. Please go through your autoexec.ash line-by-line and verify every single address and command. Something's up, for sure. Please share when you do figure out what's up, though!

That's the point. My card is fast enough to support 35mbits. And moreover I've always used custom firmware and never ever had this issues. That's why I posted the issue.

Hi guys,

I have received my new Yi (23L) with its Tochiba U3 128 GB card and now a question about the Yi camera connectivity:

Is not it possible to simply connect the Yi with the USB cable to my computer and copy the files over?

My card reader on my computer is broken and therefore I cannot use it directly.

Thanks, mates.
