Super slow motion (960fps) bigger than 10s - Is possible? - Xiaomi Mi 9 Questions & Answers

I was frustrated to find that it is not possible to record super slo-mo for more than 10 seconds. Does anyone know a way around this? Thankful.

960 fps is only a software process. Therefore, it is done only with stock application. However, Filmic Pro application can shoot longer with 120 or 240 fps. However, auto focus does not work.

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.

Can't lock 4K 60 fps in the camera settings

Hi, In the camera settings I can't lock the video to be 4K 60 fps, it lately just switch back to 30 fps and it is really frustrating. Do you know I can report this problem to Realme or solution to stick to 60 fps? Thanks!
I tested on mine and it does lock 4K with 60 fps, but not when you have video stabilisation on.
It will automatically switch back to 1080p. I can't seem to replicate your problem. Perhaps you can test it with another app (most people like GCam as an alternative) and see if it is just in the default app doing that.
Also, which version of the phone are you using, CN or EU? And are you on the latest ColourOS (XXXX11_A.12)?

It's stay on 60 fps for awhile but like after some time. Maybe they kill all camera activities it switch to 4K 30fps. Yeah, I want to use default camera. GCam is good for photo, but the video is trash. I have EU, latest is A.12?? Can you give me link? I only know that the last one is https://www.realme.com/in/support/software-update RMX1931EX_11_A.07.
Thanks for reply btw.
I have the exact same problem, I think it is a China ROM problem. I think a bought a beautiful smartphone, but China rom sucks.
Well, I have eu version. So, it's not only cn problem. But I believe they will fix it in Coloros 7.

Slow motion videos

Ok, so I've had my Mi8 for over a year now and I love this phone very much.
I still think its camera is one of the best out there and I've been thinking about using its slow motion video recording for some scientific projects, but here's the catch: I'd like to use it's 1080p 240 FPS footage, though interpolated through my desktop PC, which has a decent amount of powerful hardware (Ryzen 5 2600, 16Gb, GTX970), to 480 or 960 FPS. I don't really like the effect that the phone's interpolated 960 FPS has and I'd also like to record more than a few seconds maybe one or two minutes which in 240 FPS is possible.
Well, every time I try to open the video file in an editor I get an error saying that the video is incompatible or corrupt (I've tried this in both smartphone apps and PC: Kinemaster and Premiere, although only the latter can interpolate). But in every case I could open the video in the phone and in the PCs video playback software (VLC and MPC) normally. So I was wondering if it'd be possible to convert the file to a compatible format for interpolation. In this case, I think the conversion NEEDS to maintain the framerates. Correct me if I'm wrong though, I've never tried this before and have no prior experience with these softwares (video conversion, editing, etc.).

Samsung Galaxy S10 camera SlowMo Functionality Android 10-11

Hi Everyone !
I was wondering how slowmo video storage work with Android 10-11, on Galaxy S10 ?
I am actually on Android 9, UI vers 1.1.
So, when i am recording slowmo vids, i can save and export them with the same FPS they were recorded with (in my case setup is on 240 FPS).
From my experience on a Galaxy S9, on android 10, things were a bit different! If i still was able to record in high FPS for slowmo, when it comes to save and export them, it was only 30 FPS, and only playing in slowmo. Not very useful or convenient when you want to posprod !!! (i am usin mediainfo to get the information).
But when i go back to the original recording, it shows 240 FPS.
Do you know if there is a way to get the video file untouched ?
For exemple, i want to record 15 sec at 240 FPS, but i want to export them like that (no slowmo while playing the video, before post production)
Thanks to every one who read me.

Question Video 4k 60 fps 10 bit artifacts

Hi,
I wanted to know if this is normal on Xiaomi mi 11 Ultra, but
when I shoot in 4k 60 fps in HDR10+ (10 bit colors), I'm getting weird artifacts in the video. Look at: StockCamera10Bit.jpg
It's such an unusable mess. I'm shooting at PRO. It doesn't matter what ISO, shutter speed and white balance is selected. It's always this. Subject has to be moving.
If I select 8bit, it's ok, just normal motion blur.
Is it normal on this phone? Can anybody confirm it?
I have the same problem in McPro24FPS in anything over 30 FPS even in 8 bits, so that's troubling me a bit.
I have the phone for a few weeks now and it's just amazing how the video footage degrades, when you do not want to film in AUTO
And even, if you satisfy with AUTO and only lock exposure and focus, it's also crap, when you move the camera or something is moving in front of it
I can see, that the only thing that manufacturers are interested in is AUTO mode which gives you nice HDR, but is always changing exposure, so it's interesting only for YouTube reviewers and DXOMark I guess. But for semi-serious video shooter I'm still amazed how they market 8k video and I cannot get even decent 4k 60 fps for slow mo (not even usable Full HD in 60 FPS).
I would satisfy with 8 bit, but it's unusable in stock app, because it's changing exposure even if it's locked and other app give me these artifacts anyway...
wait... did they convert 8-bit to 10-bit using bad dithering?

Alexander from McPro24FPS said, that it is a bug in HDR merging. It should have phones with HDR on by default.
It is some setting, that can be be turned off programmatically, but it's the matter of finding it.
