720p recording quality Galaxy Tab 2 7" - Galaxy Tab 2 General

Hi
Just bought GT-P3110 with stock 4.11 rom
During recording @720p camera automatically switches to digital zoom which is not good.
It is forced by hardware sensor or theoretically can be fixed by software tweak, custom rom or anything ?
PS. Does anyone know if the sensor (S5K5CCGX) is used in other devices?
If so, does on these devices video record quality and zoom problem is the same?

HELP
having this same problem with newly purchased gt-p3113 with android 4.1.1 its zoomed in in 720p record mode? bug? is there a fix? anyone?!?!!?

this is aint a soft bug nor a hard bug it is the frame of the sensor 1080p take more in the frame but 720p has half frames also the sensor is fixed foucs so must accept this but it is not a bug

[Q] 720p Recording

Hi,
Does the HD2 Leo support 720p recording ? I heard it did ? Also i heard it will be capable on android running it from the HD2.
If true... why is it not possible on Windows Mobile ??
Thx!
i guess its because of the camera driver.

Oh come on! This has been gone over so many times!
Winmo doesn't support the drivers, that and It can hardly handle the video at that resolution
Ok so is android on the hd2 capeble recording 720p? (with the right drivers) ?
Not yet. No one has managed to get 720p recording to work even with Android though I believe progress is being made.
Don't get your hopes up with 720 capability saving this phone's camera. Just imagine the picture quality of the camera now, just way bigger. The lens is just not the best.

Lens is capable of taking up to 5mp pics. So 720p recording is possible, but framerate may be low.

DEsire HD 1080p

ORiginal desire got the ability to record 720p videos . Even iPhone 3gs which was able to record vga video was able to record in 720p after a work around.will it be possible on desire HD to record full hd 1080p videos with any kind of work around

I'm not a techie but 720p usually means 1280 by 720 pixels where 1080p means 1920 by 1080 pixels. It's quite a jump between those values and even with a workaround that quality could be poop
the sensor won't be better with any change
It will just use more space from the sdcard
The sensor is capable of recording 1080p, but the processor is not capable of encoding in full hd. So no - it's not possible.

i agree, the sensor is the same size so the image will just be stretched and more space used for the same image quality

Nope, if the processor was capable of encoding 1080p, the video won't be just an upsampled version of the 720p video. It would be a true 1080. It's not the sensor alone that's responsible for the video quality - there are the lenses and the hardware encoding. And these (especialy the lenses) have the negative impact on our video recording IMO.
If not full HD then least some workaround to improve the current state. Audio really suck and video I dark most of the times. Really disappointed with the video quality on desire HD

Htc have always had ****ty cameras. If you wanted a camera phone the dhd isn't the best option.

Someone Swyped my idea.
to be able to record in 1080p would be great enhance but I bet changing from stock sd card is required it seems. class to won't do good with 1080p recording. correct me if I'm wrong
I wouldn't have thought a Class 2 card would anywhere near fast enough for full HD.
would you really notice the difference from 720p to 1080p if shot through the same lens?

Not with these lenses
the lens is capable enough to record 1080p,its the processor issue,because the new galaxy s2 has 8mpixel camera aswell and is capable of recording in full hd 1080p,so i was wondering,if i overclock my cpu to 1.2ghz,which i already done,will there be a solution?

Galaxy S2 has a dual core CPU.
We would need that, if we ever manage to capture in 1080p it would just be a slideshow because the CPU cant keep up.

[Q] 120Fps video recording?

Is it possible to get 120fps video from u8800's camera? Even with lower resolution? 'cause it would be cool to have smooth slo-mo camera.
I only saw this function in a mid-costed digital camera. There is a big doubt that it's possible on u8800s camera. I guess, the deal is in camera driver or in hardware limitations. In any case, it's fatal for your request.

[Q] Bad quality 4K recording.

I bought myself a Note 3(N9005, 32GB version) few days ago, but since the beginning I have had a problem with recording 4K videos. To be exact, it doesn't record at the promised 45-50 mbps bitrate, instead it records at 10 mbps or even lesser bitrate. So my question would be, how can I fix that?
All the other featured modes are working flawlessly. Would really appreciate some help. The phone is not rooted or customized in any way.
Thanks in advance!

Yes, under the video resolution section I chose 3840x2160. Is there supposed to be some more options to improve the quality?

Downscaled 4K looks much better though, so there is a huge benefit in making 4K videos. Anyway it seems like those crappy units of Note 3-s made their way only to Estonia, since me and shizny are both from Estonia and there is no more information about that problem on the internet, atleast I couldn't find absolutely nothing on such weirdness.
Actually jaythenut is correct. Though the Note 3 is capable of recording video for playback on a 4K TV your device having only a 1080p display is not going to appear different at all.
The Note 3 plays back recorded 4K Video in 1080p on both the phone and any other playable media device as it can't process anything higher than that.
Your better off recording videos in 1080p at the now 60f/s.

no one is right.
quality of recorded videos playback is not the same as seen on youtube, by other peeps recordings.
check the quality, bitrate of 4K recorded video on my device is 6000kbps, 1080p is 15000kbps.
If you think a little logically then how come 4K recorded video is worse than 1080p? Even the playback quality is worse, not only on the device itself, but also on monitor.
Have you ever watched 1080p video on 720 display? Any difference? Video is crispy and detailed, Now how about 520p video on 1080p screen?
Now this is the same as my 4K recording on 1080p screen.
Either the device is faulty and cannot record/play 4K videos or sample videos made on youtube are actually 1080p.
This is really strange. I'm from Estonia as well and I'm facing the exact same problems. All my 4K videos look like 240p ones or even worse.
(Can't post the full YT links because of my postcount, but here's the v-codes)
watch?v=4iEt7lGGPqk- 4K sample
watch?v=4fryaJ6cfw4 - 1080p sample for comparison
I can't find anything on the internet regarding this subject, does anyone have any idea what the hell is going on? I sent an email to Samsung support about this as well.
the same problem here (lithuania), firmware N9005XXUBMJ1
Wait for while there will b some patches to fix it.all devices havr same problem
Same here. 4K recording quality (and, of course, bitrate) is awful. Videos looks like 240p.

EDIT: Ok, it seems that this is common issue with particular batch of this model (maybe it only affects the Baltic countries), and service centers are aware of this problem.

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:

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.

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.
