Hi, I am very curious about the new iPhone's ability to record video at VGA 30fps having only a 3.0 MP camera onboard. If that is possible for iPhone 3G S, would that not also be possible for HTC Dream? Is this a software issue or a hardware issue? I always thought that VGA recording is only possible for phones with 5MP quality or something.
Would appreciate if someone can explain to me this part of Video Recording. Thank you!
The mega pixels really doesn't have anything to do with the frames p/s recording rate. While something of a better quality can be achieved at 30 p/s I would not think it too essential for a phone and 24 is more than adequate. If one is trying to shoot a movie, then I would imagine that a video cam would be a little better I think it is really just hype... ooooh my iPhone can record at 30 frames p/s ... trust me it's not a big deal really.
I'm just curious and want to know if the hardware in the HD2 is capable of higher quality video recording
OK so I have been looking at other phones with a 5MP camera and they can record video higher than 640x480.
One example is the N900. It can record up to 848x480.
Another example, the Droid can record 720x480.
Thx
Why are you posting multiple threads asking the same question (i.e., the other thread here)? You think someone will magically say yes?
For Windows Mobile, it is unlikely you'll see anyone develop any improved drivers for higher resolution video camera recording.
If you're unhappy with this fact, sell the phone and buy the phone that comes with the resolution you want to record at if video recording is so important to you. Didn't you even do your homework prior to buying the HD2?
I only asked if the hardware is capable of a higher resolution.
The hardware.
Read before you answer, ty.

Do you really feel the HD2 video recoring its bad. I maybe used the recoring on my phone maybe 4 times in my entire life. The recording its above decent. There might be a hack for it but I doubt people actually dislike the quality of it
It's not so much a question of hardware as it is a question of software and drivers.

Well it could be a hardware issue too. most camera sensors have a still picture mode and a video mode. If the video mode is only designed to do 640x480 then that's all your gona get. Sure an app may be able to be written to capture video frame by frame in still pic mode, but can the camera take pics that fast? does the sensor module to motherboard link have the bandwidth to do 5mpixel at 30fps? i doubt it. im guessing that the link between the module and motherboard is either an I2C serial bus or maybe just standard USB, Though in video mode the camera module itself might be doing the mp4 encoding, taking that workload off the CPU, if you tried to capture frame by frame, then your going to have the CPU convert either the raw data or jpeg data from the module into a video format.
I firmware hack or mod for the camera module might be able to enable say 720p video output from the module, but i find it doubtful that anyone is going to get their hands on that firmware and we dont even know if it is "field programmable"
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
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.
USing Ornyx05 - 0709 port.

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.
This has been bugging the hell out of me since I got this phone. All the reviews made such a huge deal out of the phones camera quality and capabilities. But upon using it myself.. I am not all that impressed. When I record a video in say 1280x720, the resulting video always looks like it was recorded in say 800x450 or something along those lines. No matter what bitrate I choose, it looks like a lower resolution. You can't zoom the video hardly without it degrading. Go ahead, try zooming on some text in 720P. Now compare it to 720P on some other phone. Now, when I record in say 1920x1080, the resulting video looks like it was recorded in 720p, not 1080.
I have 720p videos I recorded from my Galaxy S4 that look FAR FAR better than so called 720p on the V20. It seems like the camera on the V20 is UPSCALING the video recording output to the next highest resolution than what is ACTUALLY being recorded. 720p appears as 480p, 1080p appears as 720p etc. As someone who is picky about quality, this has been a major blow since I got this phone. I am surprised no one has ever posted about this.

Iv noticed it, but I brushed it off as I felt nothing could be done to fix by me or other devs that I am/was aware of. Now that I think if it more from your words, maybe could be fixed by overclocking the 4k to 6k, or 8k, to get a 4k resolution. Need root to try this though.
Well, at least I'm not the only one who noticed. Is it the same way on Oreo? I mean, did the update "fix" anything related to video recording resolution or is it still upscaled? (I'm still on 7.0 Nougat for battery reasons, but if 8.0 has a video improvement.. well, game changer). This seems like false advertising meant to try and push 4k capability when it really couldn't. If the camera really isn't capturing 4K, then does that mean it would be too much a burden on the hardware to actually be pulling 30 4k FPS ...VS 30 1080P FPS upscaled to 4K?
Are you talking about the quality on Google photos, or the out of camera quality?
have you tried exporting it to your computer via USB? Cos, for some reason the quality and resolution are lower on G Photos.

I don't think a burden but more of how's it's coded. 4K on tripod is hard to tell vs 1080p. Note 3 was same way. Oreo cam may be better but I can't really tell. Idk why 16mp is not fully utilized for 4K 16:9 either. Coding that I personally don't know how to do. Slow mo don't even have sound via stock cam.

Camera output. That is, the resulting video file from the camera after pressing record button.
I know there is a loss of quality from compression. But it's not compression artifacts causing this. Bitrate doesn't make any difference. You can clearly see the video detail is not even close to what it says it is. I especially noticed this with text. I was recording a video while in a car. There was a car maybe 1-2 car lengths ahead. One can easily read the license plate. In the recorded 1280x720 video, I could NOT make out the plate at all. You'd thought I recorded in 960x540 or close. It's rather blurry. I think that's why LG added all that oversharpening.
I even set it to take photos at 1280x720. And even with high jpg compression zoomed/cropped, it doesn't look like the 1280x720 zoomed/cropped video of the same exact item being photo'd.
Been using Mark Harmons OpenCamera and trying all sorts of video bitrates. Then changing photo save resolution. I found that a photo resolution of between 960x540 and 800x480 (cropped) looks very similar to what a cropped 720P video appears. It seems as if there is some kind of preprocessing going on with the image that makes it appear extremely muddy (smudged blurry detail cropped). Nothing at all changed with the quality whether the bitrate was set at 5Mbps or 50Mbps. Quality remained unchanged.

Sounds like Oreo update isn't worth the trouble. As far as how it's coded... I think it's the awful preprocessing muddying up the image detail as I mentioned above. Using massively high bitrates does no good at all.
4K on tripod VS 1080 on tripod is quite noticeable on the V20 due to the appearance of upscaling (or horrible preprocessing.. whichever it is).
I didn't know Slo-Mo was supposed to have sound. I mean, the option to enable sound would be interesting (say a time-stretched audio instead of slowed down pitch).

Who wouldn't want sound with slow mo? That's like no sound with regular video lol.
LG also made it to where 4k can barely be done via third party. Gcam can't...Open Cam can. Nothing can be done without root tho. Even then... limitations upon availability and know how. Manual setting is your best bet. Auto is well...auto, so definitely postprocessing will be involved and yes it's not the best, unless fixed with some mod, even if that works. LG hardcoded lockdowns. Camera firmware can be possible tweaked...but I do not know how.
