960fps Slo Mo Video - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

How to increase the default duration of 10seconds in 960fps mode? Is there any way to natively enable it or any third party app?

960fps on this phone is fake interpolated slow motion, you get errors and artifacts in your video, plus it's almost impossible to time correctly and record what you want. it is actually 240fps but slowed to 960 in software.
120 and 240fps is recorded in true slow motion (and 1080p), so you get whole frames without artifacts and can record the whole video and trim the parts you don't need.
if you need it slower you can import it to your computer and use any editing software to slow it down further, but depending on the type of motion you will get artifacts and errors in your video.
you can google the (short) list of phones that have true 960fps slow motion capabilities.

Thank u very much.

Quick question about video recording

is it possible to zoom during making slow motion videos? (yes i know quality would then suffer....but it it possible?)
alsowhen making a slow motion movie do you have to edit it always to make it slow motion or when played back immediatly after recording, is it slow motion already? (on htc website i saw you need to click edit video first)
thanks!
Seriously is this so hard to answer?:/

Slow motion video is lacking..any other options?

All,
Been testing the slow motion video on my Note 5 and the quality is pretty bad compared to the Iphone 6. I been researching a bit and read that the Note 5 slow motion records at 720p @120fps as oppose to the Iphone 6 240fps.
Was wondering if there is other work arounds for a better slow motion effect. Like record a regular video at 1080p @60fps and video edit to slow mo? Is that possible or are we stuck with what we have? Also, if there is any type of editing, would like to edit within the phone, not export it to my laptop and do the editing.
Thanks!

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.

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.).

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.
