720p vs 1080p video recording - Galaxy S II General

Do you typically record 720p or 1080p video? I use 720p because the files are smaller and I own a 720p tv. I wondered if 720p might offer better quality in low light conditions because it can average over more pixels in the sensor?
Also if the phone cpu is working too hard at 1080p does it reduce quality by upping compression and increasing lossyness?
Or is 1080p substantially better choice with the only downside being bigger files?
Generally I've found video IQ to be some what independent of resolution (on other devices) because compression generally goes up with resolution negating a lot of the benefits.
Thoughts?

Im using 720p cos it seems to me more clear and more smooth playing...plus less zoom.....

So 720p plays back smoother? Just on the phone screen or over hdmi?

You are right, due to the binning would select the less noisier pixels and thus, the 720p video quality [except for resolution ofc ] would be much better.

I prefer 720p mode, only because of the field of view, it's just too narrow angle in 1080 mode.
Suppose it could come in handy if wanting to shoot something more distant but for indoor work it's not wide enough.

For me only 720p, because in 1080p I get a thin, purple line over the image that's also recorded into the vid, making my 1080 mode effectively broken.

I always thought 1080 as higher quality than 720p. Maybe for mobile this is different? Any source or test for this?

I'll try and shoot some comparison footage tomorrow.
Not sure if YouTube's compression will make the difference impossible to tell though.

This is a totally different matter. Yes, 1080 pixels are "higher" than 720, obviously . But there are other factors also on our device.
I just record in 720p. Never really compared the two, but I don't need 1080p usually, so I' don't need those huge files either.

Good discussion on here, guess I'll have to switch to 720p now on.

I tried recording an apple in the 2 modes and to my surprise the 720p mode is indeed much clearer and wider then 1080p.
Go for 720p

I prefer 720 p... for my the quality is enought and the size of the videos is so better.

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] Nexus 7 video resolution and video streaming

So the NExus 7 has a resolution of 1200x800, which is very close to the native 720p resolution size.
My question is, when streaming a 1080p video file on the nexus 7, will it look any better than a video size with a resolution of 1200x800 or 720p?
Wouldn't it be better to convert the resolution of 1080p videos to 1200x800 so reduce file size yet reduce absolutely no quality?
During this video http://www.youtube.com/watch?v=sOqn62m49S0#t=11m55s the guy plays a 720p file and 1080p file, they are streamed from a usb drive but how does the performance differ on the two even though they are playing on the nexus 7 screen, so are being outputted at 1200x800?
Another question I have is can I stream a 1080p video file using micro HDMI cable from the Nexus7 to a 1080p capable TV? Will the Nexus 7 GPU output 1080p on the TV full screen?
Help is very much appreciated!

The nexus 7 doesn't have a micro hdmi. So that's not gonna work. Only a mini USB but you can use an otg (on the go) cable to attach a flashdrive with movies you would like to watch. 1080P and 720P are compressed differently. 1080P is a much heavier format so if you really want the full 1080P experience your gonna have to stream the full size video which can be around 10gb. By reducing a 1080P video you can stream it easier and it will still be HD but quality will be less. 1080P is always going to look better than 720P because it is compressed so many times so the picture is literally made tighter increasing clarity. Lets say you took a 5mp picture and a 8mp picture and looked at them on the nexus 7 when you look closely at the pictures you can see the clarity difference between the 5 and 8 MP. Compression is what makes the biggest difference. You are cramming more and more information into a tiny place. So 1080P will look nicer on the nexus 7 but so will 720 but the details will be clearer on 1080P even though the nexus 7 outputs in a lesser resolution. But the difference will be harder to see on a smaller screen but much more noticeable in a bigger screen. But streaming a 1080P can be choppy because eventhough they are being displayed at the same resolution they are being input differently. Sorry for the long explanation

Ok so is it possible to make a 1080p file reduced in resolution but not as compressed? So it still includes the detail you are talking about?
I thought that the pixel resolution was the main quality aspect of a video being outputted.
For the micro usb, i meant a micro usb to hdmi cable you can buy? http://www.amazon.co.uk/Kitvision-Micro-HDMI-Adapter-Cable/dp/B005TF2F2W

Mhl is not currently supported on the nexus 7. So no micro USB to hdmi. 1080 P is the resolution so if your going to reduce that then it wouldn't be 1080P. It might be 1080 I which is less but 720 P and 1080 I equal out to the same resolution. Honestly 720P is going to give you plenty of clarity and I wouldn't stress about 1080 P. Unless you have 1080 P movies downloaded I wouldn't worry about it.

Zippox your making a mistake. You are confusing scaling and compression. Compression determines files size, clarity (less pixels). Scaling which is done by your set top box, DVD/blu-ray player, computer, smart phone, tablet just makes it fit to screen or what ever size it needs to be. Will 1080p look better on nexus then a 720p that's a yes/no answer. It will depend on how much each file was compressed. Generally a 1080p file is compressed much less then a 720p. Why? Cause its resolution is too huge. Which means compression (blocks aka pixels, seeing weird shadow/dark areas move, blurry images) can be easily seen if its not done right. If you set a 1080p file and 720p file and compress them the same bit rate as the 1080 and view it on a 7" native 720p screen you will not notice a difference. Why one will be scaled down and the other will not be scaled at all. Clarity will be equal at that point. Now once that 720p file has to scale up then its defects will be shown regardless of actual screen size. And trust me you will never stream a 10gb file. You can download a 10gb file but you will never stream that. Those stream sites actually offer two completely different files. The streaming file is much more compressed. Why server load, then actual internet speeds. That would have too much strain on the server. This is why streaming is not an alternative to actually owning the file. And the digital download is not as good as its blu-ray medium.
But scaling and compression are not the same. And you were getting them confused. There is no point in a 1080p file for the nexus 7. Unless you have it 1" from your face and straining your eyes you will not see the difference if its encoded (compressed) properly. 1080p scaled down to 1280x720 will look just how its supposed to at 1920x1080 you just need to be closer to the screen. But then make that fit on 7" and 720p scaled down. That's just waisting space on the nexus7. a 30 minute anime file at 720p is generally 250-350mb. Its 1080p counterpart is usually 700mb. And it will look the same on your tablet. The only difference will be based on source material. TV capture vs blu-ray rip.
Then there is compressors. H264 8bit, h264 10 bit, divx, xvid, wmv, mpeg2. This will also define how the video looks. H264 10bit is the current best compressor. You can have a h264 10bit compressed lower (in megabytes) then h264 8bit and it will look just as good as its higher filer size h264 8bit. But naturally they will compress it less to completely blow h264 8bit out the water.
None of this has anything to do with scaling. Scaling down you see less but still looks very clean, and clear. Scaling up makes for a sloppy mess. And lesser you compress the less of a mess it will look but it will not ever look as good as native or less. And scaling of actual screen you should never see a difference as long as resolution of screen isn't touch.
There are two meanings for scaling and 1 for compression. Scaling resolution, scaling actual TV. Compression is only for file size which determines the actual quality. Overly compress it will look horrible. There is no under compress. Scale up from files resolution will degrade any image.

N7's resolution is 1280*800 and you should use 720p video as 1080p would just be a waste of space.

Maybe I should have made it clearer. Compression and scaling are different yes. Compression is taking a file size that is large and compressing it into a smaller size to fit. So taking a 1080P picture and watching it on the nexus 7 will look great. SCALING that 1080P picture to fit a 720P picture will change its resolution so that a 1920x1080 will fit on a 1280x720 size screen. Clarity will always go down regardless. Unless you are upstaging in which case it depends on your source. ENCODING is taking that same picture and converting into a different codec say xvid to avi. How you encode that picture (bitrate, codec,resolution) will determine the output quality. So bottom line 1080P will look better than 720P. But that's why I said don't sweat it on the nexus 7 because the difference will be minor. On a last note I stream Blu-ray rips at 10gb-15gb from my PC to my xbox all the time but unless your internet has an extremely high upload you will get choppy playback. Again sorry if I wasn't clear.

[Q]

I was wondering if there was some sort of video upscaling present when videos of a lower resolution like 720p and 1080p videos are played. I mean, there's not much point in a QHD screen if even 1080p videos are pixelated, right?
What do you mean? They have to be upscaled, how else would you want to watch them? In a small window? 720p should upscale without any quality loss (1 pixel becomes 4 pixels), 1080p should look great too but with a slight, probably not noticable at such small screen size quality loss.
1080p videos look great on my Tab S 8.4 i don't see any reason why they wouldn't on the Note 4.
Sorry. Yeah, I mean lossless upscaling.

Lossless...?
Relative to the 1080p, sure, it's lossless as you don't lose any resolution from 1080p. Relative to 1440p? Well, in that case of course you lose resolution if the source video isn't 1440p.
Sorry, I'm not too sure what you mean by lossless.
Looks like I've been doing a shoddy job of explaining myself. Sorry about that.
I know that this may sound completely retarded, but what I meant to ask was this : Does the Note 4 have the same type of upscaling that is present in 4K televisions?

H.265 video codec

Hi.iwanna ask about h.265 codec setting in our axon 7. Im using a2017g on b08 firmware. Is it normal when i set video to h.265 codec and 60fps the video become slightly zoomed compared to h.264 codec? Thanks
You mean the 1080p at 60fps mode using h.265? I have noticed that also.
That's probably a sensor crop. Sometimes you see that on devices when developers want to include a format that pushes the limits of what the hardware can handle. The device will sample less than the full dimensions of what the sensor can capture so that it is processing a more manageable amount of data. It then upscales each frame to the target resolution.
Personally, I think the 1080p 60fps mode on the Axon 7 looks like garbage. It's not just cropping the sensor, it's sporadically blurry because I think it's also interpolating a certain number of frames to reach 60fps. The bitrate looks inadequate and the colors are washed out. Most SD 820 phones don't even attempt a 1080p 60fps mode. While it's a type of real time hardware encoding that the chipset technically supports, I believe the results are not desirable. It probably drops a lot of frames unless developers implement tricks to improve the raw performance as Axon has attempted.
The 4K video mode at 30fps that uses h.265 looks pretty good to me though as long as there is an adequate amount of light. There's no sensor crop, the colors look better, there's substantially less blurring, and the level of compression artifacting visible is much lower.

What about 1080p60 on the Lineage camera? I believe it looks much better than stock 1080p60.
Maybe snap is even better (caf sources?)
Also, I have no idea about this sorta stuff, but what would the bottleneck be? There's a dedicated image processing thingy on-die, right?

Never try los yet so i dont know the quality
@argblah,
Hi, have you tried this issue on other phone? Have you fixed your phone's problem?

Anyone know a way to stop the camera from upscaling the video recording resolution?

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.

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.

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.
