Video recording Higher resolution - Theory how it can be posible

Hi,
we can take photos in 3.2 megapixel, so why we can not record video in this resolution or in 1megapixel resolution?
this 3 steps maybe can work
3 easy steps
- if reason is weak processor speed? overlock it
- if reason is low ram? extend it with microSD card and apply SD-Booster
- custom recording app with modified recording resolution. or only change /data/local.prop (but not work for most phones)

what a breaktrough!!! xD if it were that simple we would have 720p recording by now

ya.. it s possible.. but it just damn hard.. may b it needs to rewrite the vid rec driver.. :/

i think he meant swap partition..

Ever thought about this:
- sensor not good enought to record 60 (or even 30/15) Photos with 3,2 MP in one second
Every other camera also needs to lower the resolution when recording video. Thats not a question of processor speed or RAM.

So...
what about this:
Apple Ipod Touch 4G
Camera
Photo: 0.7MP (960 x 720), It's VGA!
Video recording:720p 30fps, it's HD!

everything depends on the sensor......ours can handle higher res recording
but drivers need to be edited...
im trying to get a kernel with higher res but the drivers are tough and i have no
c++ experience...

Copied from android market:
SD-Booster speeds up your SD-Card (external memory-card) up to 40 times! Enjoy a new feeling of speed on your Android smartphone anytime and everywhere you are.
Starting apps, listing to your favorite music or just swapping data with your PC ? Whatever you do, the SD-Booster improve your phone speed!
SD-Booster needs root permission to run, otherwise SD-Booster can't do anything!

So try to record your PC desktop with 30fps in resolution 1280x1024 with PATA/ATA HDD and 2GHz processor (1 core) if your HDD is low it cannot save 30 images(frames) per second to your HDD without lag.
If processor is low for rendering 30 frames frames in 1280x1024 resolution into video file and if HDD is too slow to write it, it is Fail. so if in our mobile is possible to speed up read/write speed of sd card and is possible to overlock cpu from 667MHz to 1300MHz, increase the ram using swap, so hardware side is done.
I think it is possible to change /or create custom\ driver for camera and customize recording resolution to our phone.
Sensor is one, If it can capture photo in 3.2MP it can also capture 25 photos/frames\ per second in 3.2MP and render it into video file without lags.
But I think 3.2MP is too much for our devices hardware. So 720pixel is enough to record a pretty nice video.

I am only php developer so I cant help you in this :-\

you are talking about filmin a video in 3.2 megapixel?!?!? are you out of your mind? Good cameras and high end phones take video in 1080p - that is 1920x1080=2megapixels. You think our little phone can do better? Its not only about RAM, CPU, the drivers need to be reworked but there are always hardware limitations that can not be changed. I'll bet all my money that there is no possible way to get even 720p video with our phone. If we get vga (640x480) recording we can be very happy. That is really hard to do, it may even be impossible since that is 4 times the current quality and it probably takes 4 times more power from memory, CPU, GPU, RAM and 4 months of making new drivers.

not in 3.2 in 720pixel

This theory could work, but I think we need a driver re-write. Not only that, but can our GPU even display 720p +?

Someone was arguing about video in 3.2mp. Anyway, we can't even play 720p video without stutering, so recording is impossible. VGA could be possible however, lg p500 has vga recording with 600mhz CPU and better GPU, if we can get the CPU to do more job than GPU there is a chance. Unless the sensor just can't take it, then we are stuck.

we should be aiming for about 720x480 or close......
its a good res and our gpu should be able to handle it!
i can smoothly play dvd rips on mine without lag or anything at stock speed..
sensor shouldnt be a prob we just need a guy who is good with c++ knowledge
or driver writing experience....anyone?? if u need help with kernel i have successfully compiled a kernel from source and have all the necesary tools

It would be good if we were able to record in aac audio quality,and not like now - in amr.
What will give to us higher resolution if audio is horrible ?

GT-I5800 (Galaxy 3) Video Recording: increase please
Hello at all,
i use the DutchMods ROM V5.3 on my Galaxy 3. In my opinion it's a perfect firmware... but there is a thing: poor camera (Photo and Video). It don't change change from Samsung Stock one. Video has 320x240... a very poor resolution. I think there is some possibilities to increase the resolution to 640x480 (15 fps). The solution can be a post elaboration. When you save the video, the apk Interlace the photo or video. In this way you can have 640x480 video and more high megapixel in photo. The are very good routines for interlace (for example in N70 Nokia there was a program who shot 4 photos and build an high resolution photo using 4 low res photo). The same with video : 320x240 can be 640x480 video with less number of frames. It's a suggest for all custom firmwares.
Thank you at all.
Bye.

ARE YOU KIDDING ?
"I can see that SDbooster or whatever, even if it converts the r/w speed to 1TBps, its not to be used as a ram
SD card is a removable media, "if it can hold apps moved from the phone memory, IT IS MOVING. same for data and everything.."
but by no means it can be used as "Random Access Memory"
RAM is directly connected to the phone and it is permanent. Thats all a person can explain"
BTW, reason is the SCREEN RESOLUTION and LENS

Awesome video potential

I've just videoe my TV screen (with ceiling light above me too)
The stock camera app recording was fuzzy around the edge (grainy) and the TV picture wasn't that clear at all (was half zoomed in)
So then I used the LG camera app. Turned FPS to 60 and rate to 10mbit... EPIC!
Yes it uses more space, but the quality is amazing!
Anybody wanting to test video capability, download LG camera app, set FPS to 60 and check it out! (it doesn't look,great until you start recording)
Am just uploading a sample,video which is on highest settings in LG camera app. It's a whopping 250mb for just under a minute!!

If this is the app

then 60fps not supported, I just checked it out, 1 file on 30fps and 17mbit, the other file at 60fps and at 60mbit or whatever it was. Both files are at 29fps, so until sony adds a [email protected], I don't think it will be supported.

That is something else, fps means frames per second and i have just checked on my pc and the videos max out at 30.1fps.

Well in this case Hz and fps actually are the same, as long as we are talking about the captured framerate and not the outputted one, which can very well differ.
Still you're right! MX Player is detecting bull****, Media Info on my PC does show 29,716 fps.
Would have liked it to by different though, 60fps would have been great for some slowmo action

nah im sorry Hz and fps are 2 completly different things.
http://en.wikipedia.org/wiki/Hertz
http://en.wikipedia.org/wiki/Frame_rate
MX player indicated correctly, it just didnt show you fps

Hz describes a frequency and just means "per second" and normally when I use it to describe framerates people do understand what I mean, even if fps is the better word
If you take a look at my earlier Screenshot you will see that MX Player never claimed it to be Hz, it just says "Bildfrequenz", which means framerate, and does not use any unit.

you're right, the quality seems much better with lgCamera. :good:
EDIT: also took some pictures but the quality of them does not seem to be improved.

Well either way, whether it improves FPS or not (which I didn't check it.actually did), it does improve the video massively. That video was captured using the highest bitrate, which is what defines the quality of the video
video. You don't have to use maximum setting all the time, but it truly is much better than the stock app.

So no 1080p60 video mode, anyone care?

Will there be a way to possibly modify this to enable in the future? Or 3rd party camera app? I think it's a nice looking video mode and not sure what's the big deal for leaving it out if they did.

Use an app if it didn't. You can get much better control over pics and video.
Google camera is pretty basic really, not exactly something for enthusiasts.

Who said it doesn't? That would be really sad if it didn't

it has 720p 120fps and 240fps - but not 1080p60 - wow.

Look up

Apparently the 6P is capable and has the programming to do so.
Good deal, Google FINALLY added this.
For example, the N6, the hardware is fully capable, but no 3rd party (or stock) allow it to work since the .so camera files don't have a profile for 1080p60 - so even IF a camera app had the ability, the hardware doesn't have to coding to use it.
The N6 is my case in point. It can and does shoot 2160p at 30fps but CAN NOT shoot 1080p at anything higher than 30fps. Stupid, yes, absolutely. The hardware is MORE than capable, but the coding isn't there to support it.

Best camera for YouTube videos?

Hi, pals.
I'm planning to install the Aspire ROM again but I'd like to know the best camera in my case to choose on recovery... I know that some options are available on the AROMA Installer... Don't suggest me the stock one, please.
I just need a camera that the frame rate of the movies made matches with the frame rate on YouTube when the movies are uploaded.
For exemplo... I remember that I recorded some videos on 30 fps or 60 fps, I don't know very well... But on YouTube the videos appeared as 50 fps or something like that...
And I'm recording videos for YouTube so it would be cool to upload on this site the movies with the same frame rate that I really choose record...
I'm planning to come back to a custom ROM because my phone isn't so fast and is being hot frequently... And also because I'm missing some new features...
Thank you so much.

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.

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

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

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.
