i remember that the nexus one could do 720... is it possible to do that with the hd2...
Well Im sure if it can be done it will, but as it stands that's seen as a luxury (720p) and not really a necessity. We still need fully functional camcorder..
Here's to hoping though!
The hardware is there, we just need a little help from developers.
Hmmm more to HD than resolution methinks
While I'm all for our devices doing more and unlocking their full potential, have you actually seen sample nexus one "720p" videos? It looks like badly upscaled 480p video (which in reality it probably is...). For me, 720p recording and playback ain't that big a deal when the gain in quality is so minimal in terms of the larger files. But I could totally go for some 720p video playback if for nothing more than bragging rights
If you think 720 resolution is going to dramatically improve video quality then you are mistaken. You will just have a larger version of the same video. The quality really hinges on the lens and our lens is not the best.

From what i understand the nexus shoots video in dvd like quality but can playback in hd 720p. Does the nexus have the best resolution, video recording, and video playback(without researching I feel sure the 5 megapixel camera is easily outdone by other phones) on a u.s. mobile phone? Also, what are the different types of screens and how does amoled compare and why? If nexus isnt the ultimate then what's the brand and specs of a better one? And is it true thy ota's can actually improve visuals on a phone ie making the camera and recorder look better (this isnt a complaint I'm thorough impressed with the nexus visually ) i guess im basically asking for a clinic in mobile phone screens with comparisons to the stunning nexus one.Thanks
The Nexus One is the only WVGA AMOLED on the market *that I can think of* right now. However, the Droid's screen resolution is more suited for 16:9 video playback. 854/480 ~ 16/9 while 800/480 does not. The Nexus One has a better camera, though.
I have an iphone 3gs and the nexus one. Ive recorded video on both and when I transferred the video to my PC, I noticed the bitrate is on the low side compared to the iphone 3gs.
The 3gs gets 7,000+kbps while the Nexus one gets 2,000+kbps.
Knowing this, is there a way to get that bitrate to be higher? Closer to that of the 3gs? Is it due to the app or the camera on the nexus one? As good as this phone is, isnt it suppose to be better at recording video than the iphone 3gs or at the very least on par? What can I do to get the bitrate up? Its bad enough the FPS is around 17-20 compared to 30fps for the iphone 3gs but bitrate being so important to me, what can I do? I really like android OS but cant keep the phone if its video recording is going to be a couple notches lower than the 3gs. What do I do here?
That's really stupid I expected this phone to have a more capable camera. The comparison YouTube video I watched made the iPhones video recording look brighter and more vibrant with equal clarity but I thought the nexus had better specs in video recording. I know the iPhone has 3.2 MP to nexus's 5mp but I thought recording was supposed to be better on nexus.
Can anyone explain? I've read the respective specs but my eyes don't lie. And are software modifications/updates capable of increasing the quality of photos and recordings? Thanks
Also, why did I stop having a cursor when typing in xda? I had one when I got the phone...I didn't want to start a whole new thread to ask that...
I assume it may be the compression where 3gs = mov and nexus one = 3gp. However it is possible that this may be more of a hardware limitation than something as simple as compression.
I didnt even mention the audio recording which is pretty sub par. Im talking audio recording equivalent to phones from 2002. 8khz bit rate, seriously?

The wrapper doesn't mean anything. Bit-rates don't either. Both .mov and .3gp are merely the headers and footers of video files. The main block, and the one that really matters is the codec being used. I can tell you that iPhone 3GS uses H.264, and the Nexus one probably does too since it's the exclusive codec of youtube , which is today's gold standard in video compression. Now, if each phone is using the same codec, you can turn on and off settings suit your needs. If you have more processing power, you can use that to shrink the file more. If you want the best battery life, you don't compress it as much.
Having said all that, 6Mbps is rather lousy compression for VGA output if Apple is using H.264. Full frame DVD quality is around 3Mbps properly encoded, and even taking into account the 3GS has to encode in real-time, and shoots 30 progressive frames a second (DVD's are around 24fps) 4Mbps would be the max if the camera was good, which is isn't (not bashing the iPhone specifically, all cell cams suck). 7Mbps would be reasonable if you were shooting 720p, but the 3GS can't do that.
So...summarizing
The Bitrate on the iPhone video seems insanely high, wastefully high. The Nexus One seems better, but is a little too low. Then again, I don't know what you're shooting so I'm just guess. 2Mbps could be perfectly fine if there isn't much movement.

The camera has nothing to do with bitrate. Here's a random frame from an ep of House, ripped from one of my DVD's and re-encoded using the same codec used by these phones, just with the quality settings set REALLY high. The bit rate on this episode is...drum roll please...2,000Kbps. It looks far better than anything the iPhone can shoot because 1)The camera used to shoot it was really nice and expensive and 2)It was encoded and re-encoded using software and hardware a lot nicer and more capable than you can fit on a phone.

You're seriously basing your smartphone decision on its videorecording capabilities? If bitrate and/or video quality is 'so' important to you, why are you trying to record video with a phone to begin with? You can get a much better video camera for $600...
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.
Sent from my GT-I9100 using XDA App
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.
Regards
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?
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.
