According to this:
http://hispeedcams.com/lenovo-zuk-z2-pro-will-have-960fps-video-confirmed/
ZUK Z2 Pro should be capable of recording video at 960 FPS.
It is probably achieved through interpolation or something, or not at all (see Mediatek and their "[email protected] FPS").
Anyway, when you guys get hands on ZUK Z2 Pro, share your impressions and what the camera is really capable of.

Yeah it is on official site, there is 960 fps but unfortunately resolution is not mentioned.
Something is written in chinese forum that 960fps is not supported yet because there is no ZUI 2.0 yet.
So we will have to wait a little for a review.
hello everybody, as a student very intersted i made a little calcul. The snapdragon 820 is able to encode 4k video at 30fps, ie 8.29 Mega pixel at 30fps. So the sd 820 encode 248 Mpixels per seconds. So at 960fps, it means that you get about an image of 0.25 Mpixel,which is roughly a 480*640 pic. Not bad. However if some Mediatek CPU encode at 1080p 480 fps, and if the sd820 is considered better, then he can encode more than 2.09*480 Mpixel per seconds, which match 720p at 960fps. hoping for some other resolution/fps solutions from ZUI 2.0. But if there is no breaktrough for the camera then 960fps is impossible to reach( this far this speed is only achieved by pro cameras which cost thousands), meaning it's a false rumor launch by zuk for marketing aims. Wait for the reviews is my last advice. tchao
SD 801 was capable of [email protected] FPS already (h264).
SD820 is capable of 28 MPx/s (4K is 8MPx) , so theoretically, it is capable of much more than just what you mentioned. [email protected] FPS is only HEVC bottleneck.
https://www.qualcomm.com/media/documents/files/snapdragon-820-processor-product-brief.pdf
MTK claimed their SoC is capable of [email protected] with the use of a Sony's sensor which didn't even have that capability in it's datasheet.
And honestly, it's been a long time since they announced that and have you seen it ever come true?
The only mobile camera sensor capable of very high FPS up to this moment was Toshiba's T4K82 with [email protected] FPS, [email protected] fps and [email protected]
http://www.androidauthority.com/toshiba-240fps-t4k82-sensor-596203/&ved=0ahUKEwjDx_zy4f3MAhUFORQKHXP1BisQFggcMAA&usg=AFQjCNHi7pL_vdS6wb7F9fnUwtST4ip4IA&sig2=nTEBpX31ZuZS2WzWgj5VAQ
But it never appeared in a phone (or any device really), guess it was not as good as they claimed it to be...
OmniVision's OV13870 is capable of up to [email protected] through cropping and binning. However I have a feeling that they are actually the only one to be honest and admit it is not REAL 1080p. Because every slow-motion recorded with a phone I saw was like of a lower resolution then the file captained to be of. (720p looked like 360p, etc)
In my opinion, 960 FPS video recording is not possible with the mobile camera sensors which are currently at the market... Besides, iPhone always seems to come first with better slow-motion (they introduced 240FPS with a Sony sensor and nobody was able to compete woth that for more than half a year). They haven't even introduced 480FPS yet and somebody claims to have achieved 960 fps? I consoder that highly unlikely.
That is why I am looking for what comes out of ZUK Z2... If it really is a 'scam', then I say that they (ZUK and Lenovo) need to be punished...
Even if they come up with something ugly like frame interpolation.
First samples regarding the slow-motion video recording:
http://www.gizchina.com/2016/06/08/weekend-zuk-z2-pro/
So now it is confirmed - it does not record at 960 FPS. It does not even record at 240 FPS.
It records at only 120 FPS ! 720p is the resolution.. but honestly, it does not even look like 720p... more like 576p.
And the player allows you to set the playback speed... so for 960 FPS they basically play one frame 8 times....
Pretty disappointing...
Hi, has stabilization for 1080p 60 fps video been added or at least improved in latest updates. Who can confirm this ????
Never come OIS on 60 fps maybe!!! maybe eis possibble.but yet no
Saw this sample on youtube
It shows a well stabilized 60fps FHD video from the p20 pro.
Can anyone (having the latest soft update) test 60 fps FHD video Stabilization to figure out that

They can add a form of EIS but it'll never be brilliant, it's one of the reasons I wanted a new phone, the OnePlus 5 only had EIS, it's just not good enough.
With the pro though, 800 quid and no OIS throughout? Terrible to be honest.
Anyone has a credible explanation as to why OIS is not present at 1080 60? I can understand it not being available in higher resolutions but really at 1080 60, on a flagship with is marketed as (and by many agreed to be) the best camera phone of the market it's just not acceptable. Found out while waiting for my order to ship and am pretty pi$$ed.
Can we at least hope it will be added with a sw update in the future or it's not possible technically? Is the P20Pro sensor's OIS somehow bound to the 30fps?

P20 pro never had ois on its main camera, the rgb and mono. It only has ois on the telephoto 8mp lens to assist with too much vibration while zooming. The 1080p 30fps only uses eis/ais.

1080p @30fps has to be OIS??
I've been at the absolute maximum zoom limit whilst recording and the stabilization is amazing, if that's EIS then it's incredible and a lot better than any OIS i've ever seen on any device, I would say at 1080p 30fps it has OIS unless as i said it's got the best implementation of EIS i've ever seen.
Also @ the OP.
OIS by all accounts is available in the cameras on a hardware level but it's not been implemented, i read this a while ago about the p20 pro, whether or not they'll have this as a feature at some point I don't know, it wouldn't be unlike Huawei to add features but not make them active.

I read somewhere that the rgb and mono hardware moving is for autofocus not ois. It's ais (ai stabilizer) that making the recording good at stabilizing.
Oh not to mention xperia's steady shot is EIS and not OIS and it's pretty good.
So, if it's all digital, does it make even more sense to expect it being available in the future on resolutions greater than 1080 30? I mean at least 1080 60 should be standard in 2018 flagships!

Yes it's AIS. And Sony uses the same excellent stabilisation. Better than OIS hands down. I had Sony phone before. Just a shame that Huawei didn't implement it at 4k and at 60fps.

Yea it's absolutely amazing. Never seen anything like it..
yeah EIS is good.. but it crops the image too much. I prefer OIS
So sad you’ll had to buy an stabilizer device.... having the most powerfull mobile in photos of 2018.... I have my iPhone 7 Plus with FHD/60fps with stabilization in fact.... better videos with a mobile of 2016...
I wonder if those specs are true. Seems underwhelming to me if those specs were to be true.
Currently I use a Xiaomi Mi5s which (after a mod) shoots FullHD at 60fps. I expected a nex gen phone to have at least 4k 60fps.
Anyway, I know it is way to soon to know for sure, but does anyone have some hopes to mod the Mi8\SE the way to make it shoot at 60fps in 4k?
Thanks for any ideas.
PS: Is it true the Mi8\SE doesnt feature optical stabilization?
What you expect for a 240€ device? OIS with 4K @60fps? The Mi8 SE is nothing in compare to the Mi8. Forget UFS, OIS, dual GPS and so on.

I was asking if the MI8 had 4k 60fps or optical stabilization (maybe with the option to lower the frames to film 4k 30 to still have optical stabilization).
So, I rephrase my question:
1. Does the Mi8 have 4k 60fps? Some sites say yes, some say 4k 30fps.
2. Does the Mi8 have Optical Stabilization at all?
3. Does the Mi8 SE have the same camera/video specs (e.g. optical stabilization, etc.)?
I already own my Mi5s which can shoot 4k at 30fps.... -_-

But other devices can do it. Sure they cost a bit more, but that's what Mi-Devices are known for...to be outstanding. Oh well...have to wait for Mi9 or something...
I wonder if those 60fps can be unlocked somehow...i guess we have to wait for the xda devs to check out the device when released.
PS: Wait, FullHD at 30fps on the Mi8? That's a joke right?
The S845 support [email protected] and for sure you will get this option, maybe directly from Xiaomi.

You should be able to do it. Either by modifying just the media profile of the device or by modding the camera sensor libraries. However, modding libraries isn't an easy task but it's technically possible to do so if the sensor has the capabilities. If the device has a good and skilled developer community then someone will do it eventually. Also FYI, OP6 is the only new Android phone that can record at 4K on a stable 60 FPS and that's also with a 5 minute limitation. You're expecting too much bud.

60fps recording support is only added on the latest miui10 for some devices, i think we will have to wait a bit more for updated reviews. I'm more interested in the gps for the mi 8SE since it's now selling in my country for a little bit more than the price of mi 6x.
It`s a little shame that phone made in 2018 can`t record 4k 60fps while my old S4+ with SnapDragon 800 (GT-i9506) from sept 2013 can record 4k 30 fps and 4k 20 fps also with default camera app. I ordered Mi 8 from China and phone should be here in few days.

Yeah I meant for prolonged amount of times the way you can with 1080p, I think some OEM's think it isn't worth stressing the CPU out just for 3-5 mins of 4k footage
How about Zenfone 5z? Unlimited time 4k 60fps footage?
Have you tried opencamera app ?
I personally don't care about [email protected] however, we should have [email protected]

I wanna ask how can redmi note 7 have 48mp camera but snapdragon 660 only can afford until 25mp
It's fake 48mp which made by ai algorithm, you need to wait for pro version if you want the real 48mp.
But redmi 7 pro maybe use snapdragon 710 and still snapdragon 710 cant afford for 48mp

What the Samsung's sensor do, it's they stick 4 tiny pixels into one big pixel, for brightness in the images, actually there is a 12mpx camera but the result it's from a 48mpx resolution. You can look into it.
It's NOT a fake 48 mp camera. Let me explain,
The camera has physical 48million pixels , same as Sony imx586(used in redmi note 7 pro).
But let's see what's the catch about 12mp thing.
So as i said earlier, SAMSUNG GM1 SENSOR(used in redmi note 7) actually has physical 48million pixels.
What it does is, it treats every 4 pixels as 1 bigger one. So that means when we have 48(million) pixels. And 4 pixels will be bind together and made 1.
Result is we get 12(million) pixels in resulting pic.
Now this is done to get more bright images, so that each Pixel of image can get more light.

48MP Camera on Redmi Note 7 explained by C4ETech
it's the same trick used with Xiaomi's latest 20MP or 24MP front facing sensors. it combines 4 pixels into 1 bigger pixel (this is called pixel binning). for example: if you install a custom ROM on the Poco (which has a 20MP front facing camera), it will register as only 5MP, but in reality, you actually capture 20MP, combined into a 5MP picture, this tech helps with low light and creating brighter images.
so basically: the SoC registers the sensor as 12MP, but its truly 48MP.

1) 25mp is for single camera not for dual
2)It can't, the camera is just an interpolated version of a 12mp sensor thats all. Its just an edit

I don't think this is fully true
Poco video selfie is just so dark like no native binning at all. This is different to the big pixel like on mi5.

I don't think there is a phone currently that does pixel binning in video, now it's just done in photo.
Binning adds the the brightness of 4 pixels and merge then into a bigger number.
(example: 4 pixels have brightness values of 3,4,5,3 the binned number is 15(3+4+5+3), meaning that pixel is brighter, if it were averaged, it would have had a value of 3.75 ((3+4+5+3)/4) and it's not bigger than the original pixels values, meaning no brightness improvement)
(the real process of binning pixels is actually much more complicated, and simple addition may not be done)
While in video the brightness of individual is averaged(not binned) with neighbouring pixels to make 30 1080p (2.1 Mp) photos per second.
If someone understands the process of real pixel binning, then correct me if i am wrong.

Lg v30 V35 g7 v40 have super bright mode video, 2x2 4in1 pixel binning in video (4K becoming full HD), + there's adaptive fps for lowlight
HTC has multiframe subsampling processing for lowlight noiseless video
Sony has dual camera sensor fusion (normal & bw) for super high iso lowlight video
No, you're wrong
Binning isn't always about 1+2+3+4= 10, it can also be like 1+2+3+4=10 :4= 2.5 (PureView) or 1+4+4+5=4 or 1+2+3+4=1/2/3/4 (real time hdr)
And there's no averaging in lower resolution normal video processing, it's not even using all the pixels of the full sensor. That's why most flagship use 12mp 4:3 (video is cropped 16:9 8mp 4k), no wasted resolution

I did say: "the real process of binning pixels is actually much more complicated, and simple addition may not be done" i was simplifying the technical stuff. Pixel binning is also done by averaging values, though not benefiting brightness but noise reduction.
In video the camera actually sends full frame raw data to the isp, which manipulates the raw sensor data by cropping and subsampling (technically the same as binning by averaging) and then dumping that data on flash memory as a video format.
Most modern phones use subsampling by averaging because it reduces noise.
Many phones have issues with noise while filming in 4k in low light condition because the noise filtering applied to videos must be fast and efficient, where as photo noise filtering is done with much more processing.
The LG super bright video mode is most likely some kind of software trickery that forces 1080p resolution because subsampling reduces noise, and does one of two things either increase iso or increase brightness/contrast in post processing.

I believe subsampling =/= averaging
That's why lowlight video from 40mp Huawei mate 20 pro sucks so bad
Lg bright mode is a real time processing, 15-24fps, ev +1 stop (higher than max iso on auto /manual mode), 1/4 max resolution,
I've been wanting to ask this question since, Xiaomi lies a lot when it comes to phone specs. Well, it's cheap, so we can't complain.
As title.
My Snapdragon 888 ufs 3.1 phone isn't able to shot a slow motion video at 720p 480FPS for more than three seconds.
Is this a joke? What is the sense of a 3 seconds video?
My ancient OnePlus 6 can shot a 720p 480Fps video for 60 seconds.
Why Xiaomi is so poor in this matter even considering that they advertised the slow motion feature so much?
I think the basic camera is not great but have you tried gcam it offers better functionality or anx camera

Google camera crashes when trying to record a slow motion video.
Anx camera doesnt le me record slowmotions video.
How can Xiaomi advertise with such emphasis when they have the worst slow motion of the market
