^A suggestion, a question and a poll in one (Camera supported resolutions preference)

So it seems that due to some hardware bottlenecks the awesome sensor on this Xperia Arc can't do 1080p video recording at 30fps and 720p is the best they are giving us.
How about 800p or 960p at 24fps though? How about compiling a kernel that supports that, at the cost of ram of course.
^ look above the post for the poll. 960p means awesome videos but lesser ram for apps, while 480p will be good for those who do multitasking and run a lot of stuff in the background.

Some Queries Regarding E7

Hello All,
Can you answer my few queries. The camera of the phone is said to record 4k video and 1080 videos @60fps but the phone is only capable of recording 1080p @30fps. Since the note 3 with same specs can record 4k videos is it possible via software upgrade or something like that to make our camera record 4k videos.
Can Kernel source itself is enough as the base for custom rom development.??

The camera makers said that the camera is capable of capturing 4K videos but the Elife e7 cannot capture because the company hasn't provided that matching software which does it. May be that is for the future updates or flagship devices. The max you can record is 1080p at 60fps.

what do u mean by matching software it has got all the libs required foolish gionee ppl and provided libs for several omnivision sensor libs to our device..how can u record 1080p @ 60fps its 30fps only...4k is not possible till now as it uses the android camera api which has maximum of 1080p recording capabilities note3 and xperia z2 have their own api for this so they can record 4k videos

Z5 Premium not really a 4k phone

Why is it that no one has reported that the 4k resolution on the Z5 premium is only 4k when playing or filming 4k video. At all other times i.e 99% of the time, the device has normal resolution. I think its misleading by Sony regarding the way they have advertised the product. If I buy a 4k phone as Sony has described the Z5 premium, I am more interested in my home screen, normal apps and text messages etc being 4k resolution rather that the ability to film 4k video. Its not that I need such resolution for these but merely the principle.

So you'd rather have a battery that will last you for half the day? Because there's no way around it that the Premium is the first 4K phone, and Sony really played it smart where it won't be a flop by adding smart software that enables 4K when it's needed.

No I'd rather Sony did not push the Z5 as a 4k phone when it isn't. I would have bought it for the screen size alone. The BS about it being a native 4k screen is poor customer service. If battery will be an issue they should have put a bigger battery in. it's thick enough.
What I am also puzzled about are all these journalists with their previews and hands on reviews stating how the screen is great or that they can't tell the difference from a normal phone. Did these chumps not know that's because it isn't a 4k screen most of the time.

They did put 4k resolution hardware they just did not used due to fact that it is little difference or make no difference on 2k. Their might be possible to to change resolution if you root and develop ui.

That's really no different than a 4k TV.
Unless you're watching specific 4k content on your TV, you are looking at 1080p/720p resolution. User interfaces on 4k TVs generally aren't 4k because there is no point. That dosen't make the screen NOT 4k, or the Z5P's screen NOT 4k. It's just that you have to be watching 4k content to actually see it at the proper resolution. That's how all 4k devices are, and they are all advertised as 4k, and rightfully so.
I mean I don't know what you expect... you want the browser/texting to be 4k? What's the point of UHD aside from watching videos? None of the websites you visit will be in 4k aside from when you're watching videos. Sony did the right thing here in utilizing the 4k screen for videos/pictures. There would be no point in having a 4k home screen since it would just drain a ton of battery

Are the journalists reading this site or is it a coincidence that articles about the lack of 4k on the Z5 premium now start to roll out a few days after my post. Am surprised this was not reported on day 1.

interesting

Your point is absolutely no-point. The phone is 4K phone because it has native 4K display. That the UI (applications etc.) are not native 4K is just because there is absolutely no point rendering user interface at 4K. The point is that th phone is capable of natively displaying 4K content. User Interface is not 4K content and there is a good reason behind it.

How about this article? Does it help?

My point is that 4k TV/video is not here yet. There is no content. So the 4k video feature is pointless. I don't give a monkeys about the ability to record or view 4k video.
However what a 4k screen provides is better overall picture quality. Whilst the improved ppi will not be noticeable, 4k produces better colours and brightness. This is the feature of the 4k screen that I would be interested in. At the end of the day the Z5 premium is no better than my current Z3. It definitely looks uglier than the Z3.

Funny thing is, Nobody ever complained when their phone's CPU are running on 600mhz on idle when the spec sheet is 2.3Ghz. smh

You want the phone to run at 2.3GHz when it's idle. Why?

Seems you don't get my /s implicitly there.. :/ the 4K situation looks a lot like CPU speed. It can be pushed to max but it doesn't have to be activated all the time. But here we are, people are complaining for such reserve as a drawback.

Because the OP wants 4k to run all the time.... He isn't thinking the clever mind who thought of 4k for videos and pictures only.....
I suppose he also wants the CPU to run at 2.1ghz all the time ... And the ram.... It's stated 4gig but available would be around 3.8gig.... Let's crib for that as well

Uhh what? There absolutely is 4k content. In fact, I'm watching Breaking Bad in 4k on Netflix as we speak. Lots of major streaming services are getting 4k content and there is more and more every day.
Are you upset that TV manufacturers are advertising TV's as 4K even though most content watched will currently be 1080p/720p? The TV UI's are generally not 4K. How is that different?
And just like TV's, Sony has claimed that the phone will upscale 1080p content, so it should produce better color and brightness, although who knows how noticeable it will be w/ such a small screen?

We always can see whether the panel is 4K by playing a 4K video from youtube. Like it should give the option to switch between the qualities, Am I not right?

Read this, son. It will play 4K and will UPSCALE image/video content to 4K, along with the other image/video enhancements. That's the focus of the phone, a "premium" viewing experience. The UI will remain 1080p to preserve battery life, because who the hell cares about the image quality of the freakin' UI? Same goes for apps and games, unless (maybe) the game actually comes with 4K resolution, which I doubt there are for now when consoles still struggle with 1080p.

It indeed 4K panel. only uses for Media and stuff.

Unlocking 4k video recording

I just read the x compact review on gsmarena and it says:
There is no 4K video recording - it's reserved for the high-end Xperia XZ. Just like on the other X's, it's not a chipset limitation - the S650 is fully capable in this respect - it most probably was a marketing decision.
Does that mean that theoretically it's possible to record 4k videos IF a developer looks into it and, let's say, ports the XZ camera? Basically, is it a software or hardware limitation?

well if you search this about xperia X there are some possible ways to enable 4k recording and also many have reported that other third party camera apps have the 4k option in video settings and its only disabled in stock sony camera app
but the problem is that the phone temperature might not allow us to record 4k and might damage the phone as Xperia X reportedly had issues even on 1080p recording!

Why is video recording 1080p at 60fps pixelated?

I saw it mentioned in a review, but I don't see a reason this should happen. I know this phone model vs the Mi 9 or the 9T Pro doesn't support 4K @60fps due to CPU capabilities, and for costs' sake the coupled image sensor is also a similar version which nominally identical to the Mi 9's sensor other than not supporting 4K @60fps (lower bandwidth on the image sensor's processor?). The 1080p resolution is also nominally a bit truncated due to this, with 240fps slow motion only being supported at 720fps (and 1080p going up to only 120fps), but I don't understand what's up with the pixelated quality?
With 1080p @30fps, there is no such pixelation, and zooming in even x5 keeps a pretty decent quality with no such rough pixelation. I'm not sure if the phone knows how to adjust the number of pixels used out of the entire sensor while digitally zooming instead of stretching the rendered image, but even if it's only digital crop-and-stretch, at 30fps it at the very least uses a decent filter that smoothes square pixelation.
I can see when using 60fps that the image view is slightly zoomed in, meaning it probably uses a bit less pixels out of the entire available sensor, but it's a very small difference which doesn't match the severity of the actual effect, and again — it doesn't even try to smooth the pixelation. At 120fps the pixelation is even worse.
I suppose having a higher possible bottleneck might secure more consistent performance at lower settings (so perhaps in some aspects you could expect a phone rated to capture at up to 1080p @240fps to perform better at 60fps than a phone only rated to capture at up to 1080fps @120fps), but what's going on in this case doesn't seem reasonable.
So what's your take on this? Should this issue be fixable through software update?

There's no need for a full video, even. Here are a few screenshots from recorded videos in different settings:
At 30fps, no zoom:
https://i.ibb.co/XjmqxHr/FHD30fps.png
At 30fps with X5 zoom:
https://i.ibb.co/yd6pMBs/FHD30fps-Zoom-X5.png
At 60fps, no zoom. Here you can already see some blocky pixelation along fine lines if you pay attention:
https://i.ibb.co/pL6PTkc/FHD60fps.png
At 60fps with X3 zoom. As you can see it doesn't even try to filter the upscaling, so you just end up with blocks of cubic pixels:
https://i.ibb.co/cLNcxzK/FHD60fps-Zoom-X3.png

I can definitely see the pixelation you are talking about, but is it in video itself or the pixelation is because of the video player you are using? Thats why I told you to post the original video.
Also what rom are you using?

same for my device,it has that pixelation on 1080p 60fps recording.
playing it on pc vlc or mpc-hc have it too.
was waiting for someone to create a thread about it. tnx

It is in the video itself. It shows in the camera's "viewfinder" while recording, and then the same way when playing the recorded file. As I said, 120fps is even worse, while it isn't saved at 120fps but at 30fps slow motion in case you thought it's the videoplayer mishandling 60fps playback.
I'm using the official MIUI it came with.

As I mentioned, I already saw something said about this in a review, but I don't see a reason why it should perform this bad with anything above 1080p 30fps. Because the digital zoom on 30fps remains fairly detailed even at around X3, I wonder if the sensor knows how to limit the area of pixels from the sensor used before rendering the frame, thus creating a better digital zoom than just cropping and stretching up from the normal amount of pixels being used. The image is slightly zoomed already in 60fps, as I mentioned, but seeing how it just takes the already somewhat pixelated quality and stretches it up exactly as-is in 60fps, it definitely doesn't use any sensor area limitation trickery in that case.

I have tested my own Mi9T and can say the 60fps video suffer from pixelation for sure.

has the same problem on the gcam ports too on 60fps
so i think xiaomi has to do something on the camera firmware
or imx 582 cant handle it mmm idk

This would be quite strange if it's hardware limited to this extent. Both the Snapdragon 730 and the IMX 582 are rated for 4K at 30fps, which in number of pixels per second is equal to 1080p at 120fps (which the phone also features as an option). But if this upper limit is so far from perfectly-handled that even at half the data (1080p at 60fps) it provides Crappy crappy results... Strange. Are there any other phones currently using this sensor, so we can check if there had been similar complaints?

found this it has imx 582 mi a3 with pixelation
watch?v=8YC_Zk1-cSg

That's quite strange and annoying. The SD 730 is better than the SD 665, so if it happens on both we know it's more likely related to the image sensor itself. But it seems unlikely a sensor released with specifications allowing it to capture up to 120fps at 1080p would perform this badly at 60fps. It looks as if if just takes a 720p 60fps feed and upscales it (without any scaling filters) to 1080p. Maybe it's indeed an issue with how Xiaomi implemented this sensor in software? Both phones we have as examples are from the same manufacturer, so a third party phone could be a better indicator.

Would you be so kind and tell me more in how you managed to make 1080p/60fps work on Gcam?
USing my Gcam port, the app instantly crashes when trying to use the 60fps mod....everything else works just fine.

Could you shoot an example of 1080p at 60fps, perhaps use x2 zoom as it shows the issue much more clearly on my phone, and then upload the example? Or just a screenshot of a frame.

So, months have passed and I wonder....do we have a conclusion/reason why the 1080p 60fps videos are still pixelated/jagged when zooming in even a little bid?
For the love of me i cant find anything on that matter anywhere on the web.
Is there a workaround? is it just the camera sensor? software? something else?

Still alive?
It seems to be specific to IMX582 sensors.
My POCO X3 Pro has exact same problem.
I have created an HLSL shader program to mitigate this, and it works well on MPC-HC.
I hope someone would port it to Gcam to do it in real time.
For comparison, added the stock image and one halfed then doubled.

Just for information.
This pixelation occurs also on Huawei Mate 9.
So, my thought is that may be caused by skipped scan lines to achieve 60 fps and poor interpolation for malformed Bayer array (see the attachment picture).
Considering that, I updated my HLSL shader to re-decode the array.
It should not be a perfect solution because there is theoretical restriction by non-uniformity of its subpixels.
I still looking for some way to apply the shader directly to raw pixels before encoding to H.264/H.265 in camera apps.
