is there any method to force 60 frames per second for the video camera? - Xiaomi Mi Mix 2 Questions & Answers

as the title States, I'm wondering if there's any method to achieve 60 frames per second for video capture on the rear camera, particularly in a way that doesn't utilize the lesser quality slow motion capturing method. I understand that it could simply be a hardware limitation, but it seems odd that a relatively modern flagship device isn't capable of 60 frames per second. I believe other devices using the same sensor are capable of 60fps, and I can't imagine the Snapdragon 835 isn't capable of this either.
Anyway if it's impossible that's fine, I just figured this would be the place to ask. Thanks in advance to anyone that can point me in the right direction here!
If it's relevant, I'm rooted and on lineage OS.

Terrible frame rate in video recording... disappointing

The video quality is not very good. I was under the impression (from reviews) before I bought my Desire that it would record at close to 30 frames per second (fps), but I'm only getting frame rates of 13 - 16fps which is brutal. My nokia used to record at 28 - 30fps.
Was I wrong to think the Desire would do 30fps? I know the HD recording was not coming etc, but I thought 30fps was standard.
brutal.
It is standard alright. My Nokia N95 8GB from 3 years ago took much smoother videos @30FPS. Hell, even an LG Viewty from 3 years ago can record at 120FPS and that's not even a smartphone.
We're getting 720P recording so i'm assuming they will fix the FPS issue aswell with the video recording. If they don't then I can only imagine how slow 720P recording will be.
I've noticed the same thing and am quite annoyed about it. I've realised through testing that the brighter it is, the higher the fps is. I got it up to 20fps today outside but indoors its more like 10fps even when using lower resolutions. Maybe the reviewers should have tested this rather than just quoting the specs.

what do u mean by this? is it sure that the desire will be able to record videos at 720p?

The Snapdragon CPU supports 720P encoding and decoding hat and apparently HTC confirmed that DivX and 720P recording will be coming to the Desire in an update.
Let's hope they keep their word.
Yeah I agree, the reviewers should have done their homework instead of 'guessing' the stats. I guess they thought it impossible that the Desire could have anything less than 30fps. The Nexus one is listed as 20fps minimum rate. Is it really faster than Desire?
GSM arena who are normally very reliable had 30fps as the Desire recording rate until recently. now its 15fps on their Desire stats page.
I would not even be bothered if HTC don't bring in HD video recording, once they at least bring 30fps at 800x480. I mean its a 1ghz phone with plenty of RAM, this should be a piece of pie for it to handle. My nokia had a 300mhz chip and 128mb of RAM and did it no problem. (640x480 @ 30fps)
Well personall I think the video recording is pretty good. Its definately better than my old Xperia X1.
10 - 15fps is 'passable' but not very good in real world terms. Certainly not on a cutting edge 1ghz phone thats capable (hardware wise) of recording 720p at 30fps. I used to get 30fps video from my old N82 and its more fluid than on the Desire. As I say, its passable on Desire, but I think 30fps is pretty much the accepted minimum for the past while. Lets hope it comes in an update.

Well, hope dies last. HTC and their word... Have a look at Hero topic, and search for the so called 2.1 update for Hero. Shame on HTC!
Sorry for the offtopc.
Hero update is near, as a matter of fact (tweet this week from HTC Benelux director).
I think this is a software limitation slowing the exposure on low light to brighten the image. it'd be nice to be able to adjust this feature though.

can u upload on youtube any samples as i am thinking of updating to desire from x1 as well in a week's time
there are alot of Desire made videos on youtube already. just do a search. They look 'ok', some of them, but the original files are still only about 16 - 18 fps at best! 30fps nakes the video seem more fluid. You'd really need to compare side by side to see the difference I mean. (I attached 30fps nokia clip at bottom. WOW for the difference. very obvious)
http://www.youtube.com/watch?v=Dnxcfjq3QvE (desire at 15fps)
and another
http://www.youtube.com/watch?v=rnRpOSP0U-o (desire at 15fps)
and now compare to the lower res 640x480 Nokia but filmed at almost double frame rate of 30fps. Very fluid and sharp.
http://www.youtube.com/watch?v=ojt5LS4LFZc (Nokia X6 at 30fps)
I think alot of people will be impressed and happy enough with this level of video recording. I was just irked as I expected 30fps and thought that was pretty much the minimum on new phones now.
thx . i think the vid qlty is gud on desire .... hmmmm .... better than x1 anywayz by the looks of it
My N95 8GB outperforms the Desire in video recording. What's the point in a high res video camera if it records at 15fps?
I get 12fps indoors... haven't seen higher in over 50 recordings. Colour reproduction is also off. N95 sure does beat the pants off it in this area.

How do you tell what frames per second you're getting? Can't seem to find anything in the phone that will tell me.
Well now there is root acces. So this means we can put custom roms on our decvice and/or we can adjust the build.prop so we can also adjust the camera settings...
Personally I think there is no need to worry. Just have patience
Cheers Bart. Patience it is.
Meson1 I use a codec analyser like 'gspot' to look at the details and properties of the video files. If you use Windows 7 you can also just click on the file in explorer and it displays the frame rate and associated details at the bottom of screen.
Its easier to just long press the video and select details to see the frame rate and other info.

Your 720 Experience

Hi I want to start this post so everyone can post their experience with the new 720 Recording Feature on the HTC Desire!
Please post Like this:

Problems
FPS
Rom used
I'll start:
http://www.youtube.com/watch?v=NxxPdPd8ea4
Description:
Me being very concentrated while playing the Drums... new song Bad Lighting hard sound situation (way too loud for this little Phone ) so worst case
Problems:
I see constant drops in FPS, or more likely a stuttering ever few seconds video playback just kida stops, audio is fine though! I did not have this Problems with other Roms so I think its not my SD card acting up?
FPS: 5-11 not very constant at all, although lighting was very constant (although very bad)
ROM used: LeeDroid 7.1b
Before official update:
http://www.youtube.com/watch?v=ugjI5ygsXzQ
Average/good lighting
20fps
Can't remember the rom, I think MCR v5, it was before the official update.
Not a lot of stuttering that I can notice, but the lens cover was a bit smudged and so the video came out a bit opaque.
After the update:
http://www.youtube.com/watch?v=S6KuPCn6_2M [quality should improve in a bit]
Probably a tad better lighting conditions
23fps
ieftm semi-stock rom
This is the best sample of three, one was ok, but the last one was stuttering quite a bit, as I think some background program was accessing the sd card heavily. Also lens here was a bit dirty
by the way, youtube quality doesn't render properly, linking videos should be better.

No, I think it was me that turned contrast a bit too high and the fact that without optical zoom or camera lens optics you can get lose details in the distance on such high resolution
I gave up 720p, it is not good. Jumpy, low fps and especially ****ty voice quality.
I use 480p, but it is also not good, not too jumpy ... still ****ty voice quality.
I have 2.2 rom from here and 720p keeps freezing every few seconds.
720p is ok for me. Is it possible that its to do with the internal memory available? I have 60mb or more free, I know some people are down to low numbers. my card is a class2 too. I think the clips look better played on the PC in VLC lpayer than when I upload them to youtube. I think youtube might be introducing some of the negative aspects seen... maybe?

Please please please... Can we please take advantage of the user interface of the XDA site?
For six months XDA has now supported YouTube embeds -- You can even see the icon in the COMPOSE screens -- though admittedly they don't tell you how to use it very easily.
BEHOLD! It's your video, and I don't have to click a new tab to see it. Magic!
Format for YouTube Embeds:

From your video above, the part that goes in between the [ youtube ] brackets follows v= NxxPdPd8ea4
Please, could you edit your first post to include the instructions. It has taken years to get XDA to embrace video. Now that they have, please support svetius, the User Experience designer of the new site, and use the tools. That's why they're here. Thank you.

I gotta applaud you. I have used Apple products for 25 years. And I currently use primarily Mac computers, but I also use Windows machines. Very agnostic.

And even though I have wanted my Desire to match or exceed the 720p capability of iphone4 -- i was at the Apple store a few weeks ago getting my damp MBP repaired for 3rd time and played with the iP4 -- and the 720p recording is pretty damn good. ... Lastly -- are you familiar with the various TEST PROJECTS that have been going on here since the Nexus One to optimize 720p in this HTC class of phones? If not, search... There are a whole bunch of serious collaborative engineering projects here, and as always XDA-devs work miracles -- so I'm not giving up hope yet. We may smash that iphone yet in recoding quality -- though I doubt it... I am told it records 30fps and no matter what backflips are done here, thru Froyo or other enhancements, we can't get this hardware to meet or exceed that. Is that true?
720p is crap, its just upscale from lover res., dont use it.
more info:
The data rate of 720p is over 4 times greater than 800x480. 6000kb/sec versus 1200kb/sec. It's not purely upscaled at all. I made two sample videos of a page of text and compared.
There was ALOT more detail in the 720p video. Even when I zoomed up the 800x480 one. I agree it's not as good as "true 720 HD" but its certainly not 100% upscaled.

1200:6000 it's 5 times more. Yes it's not true 720 hd, but I can perfectly live with that quality if we get a couple of fps more
I've taken two short videos of a label, took screenshots from video player, cropped them, resized the 480 to fit the same size as the 720 one. It's very blurry compared to the normal 720p. See the hour in the fake pda, you can't read it in the upscaled one.
Video upscalers tend to do a better job than a simple photo resize and they do introduce more data leading to a larger file size. The disire may truly just upscale the video after all. In any case, its a shame that video capture on this device is as poor as it is. I dislike Apple and their iphone, but i'll give them this; all aspects of the software work very well from go and if not, a fix/upgrade is provided in a reasonably short time.

Given the current state of their last shiny toy, I think it's a bit funny to say so.
Anyway, I've done some more tests and I can take the screen captured from a 480 video and upscale it with any tool with best quality or other algorythms and you always end up with a lot less detail than 720p, especially when there is a lot of light (unlike that test above). I don't think the desire has the processing power to do a better upscale than what I'm trying and while there might be a bit of upscaling given you have a tiny lens, it's not all there.
Also any tiny lens without zoom is pointless when taking videos from the distance anyway.
I can only get 15-16 fps... anyone can do higher?
I can easily get 25 average, outside in. good lighting, with a class 6 sd

I talked to some iPhone engineers about how the iPhone can archive 30Fps ... its because all the decoding of pictures delivered by the camera is handled by the GPU... for Android its all done on the CPU! so we need to find a way to decode the video stream using the Desires GPU, but I think the iP4's GPU is far better than the Desires... i am a hardware engineer... i am in no way able to code anything like that! What Makes me curios is file size comparison between an iP4 and the Desire.
Also: Desire running a non sense rom (AOSP) just like the Nexus gives much better 720 Quality!!! so I guess its in the software

SInce I am NEITHER a hardware nor software engineer, I am useless here, other than to ask obvious questions. Your apple access to methodology of iP4's video capture is itself useful information -- something that if I were a software engineer working on the various test projects here at XDA, I would want to know. Maybe that's something they could infer, or maybe its published somewhere, or maybe it's one of those "Geez, it's so obvious do i really need to be told that?" points.
That then gets blurred and muddied by the REAL armchair knowitalls (*I* disclose that I know nothing) who pounce on a pronouncement by someone here and say "That's impossible, or that's bullcrap, look here at my image, it proves you wrong, end of story" -- only to often find --- NOT end of story and that person got it wrong.
All i know is -- my experience has told me never presume -- because this site is SO HUGE, it is actually quite often that the right hand doesn't know what left hand is up to.
I wish there were a better means of coordinating the total knowledge holders of XDA site on this 720p issue regarding TOTAL CAPABILITY, software and hardware, so there is 100% collaboration. In the end, there is only one answer: Yes, desire can meet or exceed iphone4 720 p in every measure of resolution, or not.

Which is bigger? what is your initial inference? larger file size = higher rez?
thank you
roufianos cooked a Rom that achieved 29-30 fps but the phone restarted after 50 seconds of recording. Was that due to overheating of the processor? I don't know. His phone gave up spirit and he is waiting for a replacement so the development of his Rom is on pause at the moment.

I just compared the youtube clip to the original on my PC (i scaled the VLC window down to the same size as playing the youtube clip in its 'expanded' size) and there is definatly a small quality difference. The details on the original are noticable finer, so even @ 720p on youtube the bitrate must take a small hit.
Here is a screenshot of the comparison.

Note 2 cam actualy rec at 120FPS?? doubt it.

our version of the slow motion camera seems like junk.. i thought i read that the actual note 2 ups the fps for slowmo.. it seems that our version just slows down the og video at 30fps...
Not sure if this has been mentioned yet.. but is it even possible for our hardware to record 120 fps? if so why not have it record at that all the time to increase quality?

****ty slow motion of ZenFone 2

The slow motion video of ZenFone 2 ze551ml sucks.....its just 30fps video which runs at 6fps so as to give it a feel of slow motion which is badly sucks at it......it is a toshiba t4k37 which is capable of 720p @60fps & 180p @60fps & [email protected]
Proper development should unlock its capablities....plz take a look at this
I agree a real slow motion would be great

Xiaomi's slow motion isn't that good either. I own a mi3w which costs more than the ZenFone 2. To be honest this device is just as good if not better than Xiaomi. I honestly don't think I'll ever buy another Xiaomi again as they have a lot of cons. They just make the phone look good in specs everything else in the phone is just crap at best.
1+2 had some nice slow motion.

Dude my ZenFone 2 64gb 4g ram was $269 (with free shipping) with a free ASUS 10050 mah battery bank and my mi3w cost me $289 (plus $20 shipping). If you found a mi3w for around $200 it's probably a fake with the mediatek chipset.
Don't get me wrong the Xiaomi is a great phone if you never want to hear a call in your pocket, wake up to alarm, have cell phone signal inside buildings or want to be able to lock onto GPS satellites then yeah it's a great device. It also has a poorly designed charging port that ruins your cables (ruined 3 cables already) and eventually craps out. I'm currently awaiting a new charging port to arrive from China after just 1 year of use.

By the way, the way our device does slow motion is basically the same as movies do slow motion. For example: in theaters movies play at 24fps. To achieve a slow motion scene they use a high speed camera capable of shooting up to a hundred thousand fps. So say they shot a scene at 2400fps and played it at 24fps you have slow motion. Beings our camera can't shoot hundreds of fps they shoot at the highest fps the software is capable of and lower the playback fps (30 to 6). I agree it would look a little better doing 60fps record and 12fps playback but your never going to achieve movie quality slow motion on any phone ever. Cameras like that cost thousands of dollars.

My Samsung Galaxy S4 was capable of good slow motion, i'm sure that was software based too.

Anyone please help mee
I know it's late but... I can't hold it! I love how Asus puts great hardware in their phones and then ruins everything with poorly-made software that does not exploit its hardware capabilities at a maximum level. It's not only the RAW capability that's missing, but also the slow motion recording, which is a total joke! It's just a slowed-down 30 fps video. WHY ON EARTH did they do that? To keep the humongous 1080p format? I don't care if it's a 480p video as long as it's PROPERLY slowed down. (They need to reduce the format in order to increase the frame rate, to keep hardware parameters and things safe.) Just do your goddamn job and respect the hardware capabilities that YOU opted for, Asus!
Maybe they don't have a legal obligation to make hardware components available at a max level, but they definitely have a moral obligation out of respect for the customer. Even Samsung SGH-I900 (Omnia) shoots better slow motion videos, no matter if the resolution's crap! Pity, 'cause these are amazing devices that could shoot some pretty decent (even pro quality) photography or videos! The ZX551ML is a supposed "camera phone" - it shoots great pictures, but it could have been much better.
I also love how nobody knows what camera model is in the Zenfone Zoom's rear. For instance, we all know that the front camera in both models, the ZE551ML and ZX551ML, is Omnivision's OV5670, while the Zenfone 2 has a Toshiba T4K37 rear sensor. In Zenfone Zoom (ZX551ML), the hardware-information-gathering apps only show "Fujitsu MO10M" as the camera make and model, which is the image processing engine actually, not the sensor. And as to the front camera, according to Omnivision's official papers, that little bugger is capable of shooting 60 fps 1080p VIDEOS! It is also capable of shooting 120 frames per second at a 480p resolution. I see none of these things possible in Asus' implementation or default camera app... the famous PixelMaster. I don't know who is responsible for all these things but I think I'd make "great friends" with the software engineer who made this s**t.
Anything new on this? Did you find a way to unlock the real capabilities of your device? Thank you!

120hz

So as the thread is titled I've found a 120hz settings in our 1 mk2.
here's a screenshot to prove it.
This was found using quick shortcut maker not sure if it's active or not since I've toggled it on. No crashes since it's been enabled. Feel free to chat it up about this.
This is most likely code from the xperia 5 mk2 that has been re-used to streamline the update process since it's nearly identical specs besides the screen.
Doesn't work, sadly. I double-checked with the dev-settings, that shows current fps in the top right corner, still 60
I was as excited as you are...
From what I read, it couldn't be possible (at 4k) because the snapdragon inside our phones isn't capable of 120 hz @ 4k.

i just wanted to bring attention to the topic to see if it's possible with root and a resolution change. My bootloader is still locked and I can't do further testing myself.
