the truth of 960 fps slow mo

So huawei stills refusing to tell us the truth of 960 fps.
Adobe after effect (twixtor) users will now what i am talking about.
The p20 pro is incapable of 960 fps video recording. It is just an frame interpolation technique. It may be recording only in 240 fps or 480 fps. Nevertheless, Software interpolation should be improved.
Those two videos show clearly the case
What do you think guys ?
Huawei should work more on that soft interpolation slow mo thing

Practise what, im showcasing some examples from youtube to compare p20 pro and slow mo interpolation outputs.
Frame rate interpolation is what meant by camera powered by AI, i think

Great findings, the question is is this a bug, SW limitation or hw limitation. The drone part of the video definitely show that there is something weird going on. It would be great to have the same tests with 240fps to see if the result is as sharp as it should be...
Also it might depend of firmware version, it seems they made quite a lot of changes in a short time.

Huawei lie to us....

I have recorded some videos of muzzle blasts from ww2 era rifles,(yes there is a 6 foot flame out the barrel? not much fun on the shoulder though) in 960fps, it looks just like the you tube video, the 240fps looked alot better, I slowed them down as much as I could on the computer, the 960fps was no better than the 60 FPS, in fact I think the 60 FPS on my old windows 950 was better, with the p20 pro the 960 FPS vid played frame by frame was only 30 frames.
Trying to explain that the FPS is not right to so-called experts is a nightmare! I have explained it like this to a few at Huawei and EE, If you have a camera that shoots 900 FPS and you take a 1 second vid then when you play it back you should have 900 'photos' not 30, they still think it's recorded right as as it's slowed down, they cannot see the distortion or the lack of frames, or they choose to ignore you as they have been 'trained' on this phone.
According to meta data the 960 FPS bids are recorded at 30fps, if I connect the phone to the computer, go into the phones video file and right click on a vid for the properties, it says 30gps for the 960, the 250fps is recorded around the 240 mark (the speed is variable)

It is most likely a hardware limitation Huawei worked around with software trickery to get a similar effect. My guess is that Huawei's sensor lacks the on-sensor memory cache which is required for the sensor to be able to record high frame rate video without any of the normal limitations.

That's true

The 960 fps vídeos really look like twixtor vídeos.
But one thing do not make sense.
If it is a 60fps with some sw gimmick to make a 960fps why there is a recording time limit?

Stupid from huawei

They put the same options as of the galaxy s9 to make you believe that it is real 960 fps

I still believe in some hw limitation as a rolling shutter insted of a global shutter that creates this effect similar to twixtor.
If it is only sw it would make more sense to record at 240fps without time cap and afterwards during editing let the user select the time frame to create the super slowmo.

Can anyone clarify that they get these anomalies and if so what fw are you on?
I'm assuming that some of this is software based so it's possible if that's the case that it can be improved.
Really really horrible to see this though, I did a video of some rain whilst on 110 and it was crap.
Small fast moving objects just come out wrong. Solid normal moving objects seem to be perfect.
EG: the wings on a bee from one of the first posts, you can see the blur effect

i also think it's some kind of rolling shutter issue maybe combined with a real 480fps... limiting the record time would otherwise make no sense st all...
i've made a video where it's provoked by a flickering led-illumination. If the illumination is bright it seems to get better.... cannot post the link, as i'm a newbie - some assembly needed by removing two spaces: https: //youtu .be/4bxmu6nhyho

short update on my comment: did some tests with bad/good illumination and now im pretty sure it's a rolling shutter issue (which isn't a surprise, that you need a lot of light for 960fps) videos wil follow soon...

960fps is fake (at least on the p20)
so i analyzed the video files i made with bad illumination and some movies with good illumination frame by frame and the answer is very simple: 960fps is completely fake. it's recorded at 240fps and then interpolated to 960 fps.
If the illumination is bad, it will just copy 4 times the same image which avoids the ugly artifacts. If the illumination is good it interpolates the frames in-between. it sometimes does a great job, sometimes a really bad one...
in the video here you can see the effect of the interpolation working/not working with the small droplet which stays in place for 4 consecutive frames:
https ://youtu. be/DK-A3j-mino
(again assembly required, sorry... remove the space after the "https" and before the "be")

yeah... why is huawei not just honest?!? this way they sell a product intentionally with wrong specs! (with big advertisment on the webpage as well...) to me that's fraud, nothing else.

stabilzation in 1080 60 fps

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...

Mi8/8SE only having 4k 30fps? Hack to unlock?

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...

PS: Wait, FullHD at 30fps on the Mi8? That's a joke right?

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]

How do you like it?

240 FPS 720p

Is there a way to enable recording of 240 FPS slow-mo? I really do not mind the video being at quality of 720p, If the phone is capable of 1080p @240, I do not see a reason why it would not handle higher framerate at 720p.

where did you find info that it could handle 240 fps? i thought it was more like 60 (or 120 for 720p max)? don't get me wrong, i would like to see that, but imo this is out of A2's reach.

It records video in 1080p at 60fps or 720p at 120fps.

The 660 chipset on the Mi A2 IS capable of 240FPS @ 720P.
(https://www.qualcomm.com/products/snapdragon-660-mobile-platform)
The limiting factors here would be either A.) the camera modules or B.) software implementation.
So, in theory, yes but further testing/research would have to go into determining the possibility.
This would best be a question for Xiaomi support:
https://www.mi.com/global/support/contact/
Good luck!

and C) the willingness of Xiaomi of course

^^^ Absolutely this. LOL.

Even Mi 8 lite has 240FPS @720p, it uses the same CPU, so it is a software matter, so there should be a way to enable it.

@ond96
And you're likely right but, as of now, no one on XDA has volunteered to implement such a change.
Please contact Xiaomi and inquire further with them.

1080 60 FPS too much noisy

I tried to make a video in indoor light in 4K and 1080, 60 FPS, is there a reason why 4K is much less noisy? I did not think that resolution decides how much noise is there.

4K provides you with almost 4 times the resolution of 1080P thus you will most certainly see a difference in clarity.
In running a quick test, at 1080P on the default camera app, it captures the video at a bit rate of 20.0Mbits per second.
In contrast, at 4K @ 30FPS, it captures the video at 41.9Mbits per second.
So the capture size versus the bit rate is certainly going to play a deciding factor.
But there are other ways to achieve an optimal capture rate @ 1080P.
If Xiaomi gave us the ability to utilize the High Efficiency Video Coding (H.265) and dictate our own bitrate, you'd see better capture rates @1080P.
My only other suggestion would be to seek out a third-party camera application (GCAM perhaps?) and test further.
