Xiaomi Redmi K20 Pro video recording - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I own a Xiaomi Redmi K20 Pro. As you might be aware that it rocks Qualcomm Snapdragon 855. Please check out the specs of SD 855 on the web, if you don't know already.
The chip supports HDR10+ recording at the hardware level. While I understand that you need to have a supporting camera lens to record with that color gamut, I have found it to be disturbing that the metadata of the video recorded on the camera shows Rec.601 as the record profile with Y'Cb'Cr of 4:2:0.
I want to know whether is it possible to record on this device in Rec.2020 or at least Rec.709? Does anyone have any idea?
Additionally, the chip supports 802.11ax(which I guess uses 60GHz spectrum). How to check if the fone also supports WiFi connection in this band and the WPA3?

Wow, surprisingly not a lot of people are aware of this issue.
You cloud try FreeDcam from GitHub.
You'll have to change the profiles via profile editor.
I am able to record videos in Rec.2020 using the same app on Asus 8Z.
Check out the attached screenshot to see my settings to shoot video in 10bit Rec.2020
Though, utilising the same is a pain in post processing platform (Davinci Resolve), but I fortunately found a the correct way to transform the color space.

OP3T not supporting 24fps video recording framerate?

Since our stock camera app does not have framerate settings, I tried to download Open Camera. When I set 24fps framerate, and hit record, it says, device does not support this framerate.
Anyone knows what other video recording apps that can support 24fps or is it a problem for our OP3T? I was actually planning to make a short film using this device.
Anyone?
Filmic Pro works fine so don't worry that the phone doesn't support 24fps.

K20 pro EIS problems

So one of the reasons I bought K20 was for its awesome video capabilities.
To my utter dissapointment, EIS works ONLY in stock video app. No other 2nd party app like Filmic Pro or 24pfs which I intended to use for video recording can use EIS. The huge problem is, that even on a gimbal I've got a ton of tears and stutter whithout EIS. If I use stock app with EIS + Gimbal = I've got usable footage. Otherwise - noup. As soon as you get a lot of motion in the frame - frame tears and stutter, discontinuity.
So I found that sort of solution (cannot post a link as a frsh member) - the idea is to edit with BuildProp after rooting your phone and add those lines:
persist.camera.HAL3.enabled=1
persist.camera.eis.enabled=1
But noup it didnt work. I have custom rom - miui.eu and a rooted phone. I've added suggested lines, no reslut.
Does anyone have an idea on how it would be possible to activate the damn EIS for every other app besides stock?
Hi bustedcombusted, i was thinking about buying either the k20 or the k20pro to replace my old oneplus one, i thought EIS was acessible by 3rd party apps, thats a big no go for me, have you had any sucess with EIS and 3rd party apps?
For me video stabilization works in gcam mod. Have you tried it?
Anand_theGeek
No EIS in Gcam, I think you have mistaken
try filming with the ultra wide camera 4K 30 FPS. Very good EIS
@tntgdh which version of gcam do you used? It works properly at any modes?

Mi 9T Pro: 8 minutes video limit (4K 60 FPS) and other limits: any solutions?

Hello,
Sum up
I'm looking for a good way to record 4K 60 FPS with an external microphone, and possibly using any camera of the phone.
Why
I'm trying to find a convenient way to record good quality videos with speaking subjects (interviews and such) on the phone.
I aim the best possible quality for comfort and durability. I am therefore trying to film 4K 60 FPS with an external Lavalier microphone plugged in the jack port of the phone. (I'm also using a gimbal and stands depending on the context).
I also want to sometimes use the main camera, and sometimes the wide angle lens.
Phone
I'm using a stock ROM Xiaomi Mi 9T Pro (8GB RAM/256GB Storage, Global version).
Issues
As simple as it seems, I'm encountering a few issues/limitations.
Default video app :
- doesn't seem to take an external microphone
- has mediocre but OK audio compression quality
- has an 8 minutes limit when filming 4K 60 FPS (don't know about other formats).
(My 8 minutes 4K 60 FPS video is 2.2GB, so it doesn't seem to be a file size limit)
- and it's also the only one that seems to support video recording with any lens/camera on the phone...
I'm willing to sacrifice on audio quality if someone can think of a way to use an external mic, and get rid of that 8 minutes time limitation with the default camera app.
Issues with other apps
I've tried a lot of alternate video apps, but none allowed me to record videos using the wide angle lens, or they were bugged or wouldn't take the external mic or woulldn't do 60 FPS in 4K...
- OpenCamera : Works great for everything, most stable so far, OK with external mic, no time limit and all, but no wide angle
- 4K Camera Pro : No 4K 60 FPS (limited to 30 FPS), crashes a lot, no option for using wide angle camera, takes external mic
- Cinema FV-5 Lite : No option for more than 30 FPS, 4K is limited to the pro version, no option for wide angle camera
- HedgeCam2 : Unable to even select 4K anymore after testing the app, couldn't find an option to select another camera, should take external mic, not tested that much.
- Google Camera (from Pixel) : Supports wide angle for photo, but not video. Stopped testing there.
- DJI Mimo : This is the app from my gimbal, no 4K 60 FPS (no framerate option), and won't take external microphone... So it's OK for making footage, but not interviews.
Question
For now, my best option is to forget about the wide angle and to just use Open Camera which is not 100% satisfying...
So my question is this:
Does anyone see a better option? Maybe even a ROM or an addon that could force microphone selection? I'm willing to go to custom builds at this point.
Thank you

Try filmic pro, it's not free but has a huge amount of options when it comes to resolutions, compression/container method, camera and fps, there's actually too much for me to mention, the ui is a little cluttered but I think it's down to having so much stuff

Just got the Filmic Pro app, really great even though it doesn't solve the camera switch issue. Thanks for sharing.
Sent a few suggestions to the devs, we'll see.
One boring thing is it gets back to the default (internal) mic after unplugging the external and does not go back to external when you plug it back. No big deal but might lead to errors. Also, it doesn't support the DJI Osmo Mobile 3 yet, but since the 1 and 2 are supported, it's likely a mater of time. That's awesome already that it supports some gimbals at all.
For the rest, it's pretty cool, I like the interface and ease of use, that's the most professional video app I've seen yet.
We'll see, I'm glad I've got this app in my library anyways.

Camera modding breakthrough needs help

Apparently devs managed to enable an experimental feature of the imx 586 on the Asus ZenFone 6. It's called quad hdr and it enables variable pixel exposure on third party apps and also on video, allowing for better highlights exposure, but not a fake hdr feature, a real even exposure across all image even on Instagram, chat apps etc. This is achieved through a vendor hack and is being discussed on the k20/k20 pro photography group. Unfortunately there seems to be little help for the devs there so I was hoping if someone knowledgeable could help get this feature to our device.

Question Video is Rendering Over Sharped in Streaming apps like YouTube, Prime Video and Local player's also like MX player etc.

Hello Everyone,
A few days ago, I purchased the Redmi Note10s, which worked very fine in every aspect of the smartphone, but I've found issues of video rendering in apps like YouTube and others even in 1080P.
But The Strange thing is that while playing the same video on the youtube website using Firefox browser it renders perfectly and Amazing.
Below I've attached the screenshot of the same video playing in those two different apps.
YOUTUBE:
As You'll see below the SS of the YouTube Sample is Over sharped and isn't pleasing to the eyes
FIREFOX:
In the samples of Firefox, it renders the way we want with perfect colours and sharpening.
Is this problem with Software or GPU rendering, I don't know. If anyone having this phone please share your opinions or thoughts on this, and also let me know if anyone facing the same issue.
P.S: this is my first post on XDA community, hoping XDA community will help with this problem.
i have the same issue ... i sent it to mi store to check it up for a few days and they said it was alright ...
i also checked another note 10 s device in the store .. it has the same issue
the issue exist in youtube and google chrome ....
not sure if its a software issue that will be fixed or bad qc
since u posted 20 days ago .. did u do anything about this issue ?
I have come across the thing called video decoding, which is done mainly by GPU or processor. In our phone, a MediaTek processor is used which is using a technology called MiraVision to render the HDR video which causing the issue while playing video in lower quality like 480P. Some solutions I found on Reddit is saying to disable the hardware overlays to solve the issue, as this problem already faced by redmi note 8 users. But didn't solve our issue.
But idk why I'm used to this as video of 720P is much sharper and feels good now
i kinda like it although it might have to do something with miravision
best is to ask people using realme 7 and redmi note 8

It maybe an issue with MiUI's VP9 renderer (VP9 is a new codec developed by Google as a free alternative to HEVC ,or H265).
The codec is used by default by YouTube since it offers higher compression compared to previously used H264 codec (AVC).
The codec is all fine, and it is absolutely recommended to use it since it offers better clarity and saves data at the same time.
The problem is with MiUI's VP9 rendering algorithm which is over-sharpening the video. I suggest you to contact Xiaomi to fix the issue, and disable VP9 in YouTube Vanced for time being.
If the above solution didn't work, you may try changing the decoder in MX Player [Try all 3 decoders - HW, HW+, and SW.]
If you don't observe any changes, use the mx_aio custom codec.

Pls reply if this worked or not, so that others would benefit.
Has this been fixed? is it even fixable via firmware updates?
As far as i know the Redmi Note 8 Pro has the same problem and still has it to this day
I was going to pick this phone up for my mother by this is definitely a turn off

try chaging the codec override in vanced setting , also to enable extra options in the override menu tap many times on about to unlock hidden setting
Begonia user here. .as for most possible fix
change "ro.vendor.mtk_pq_support" from 2 to 0 (in Vendor/Build.prop)
*well, it need root access to do that.
I also have the same problem on JMGO O1 projector. Every time I play another video I have to go into settings and adjust the sharpness, from 0 to 1 then back to 0.
