Hello, I was reading a Galaxy Note 4 review and came across 2x lossless zooming for 30fps 1080p video recording and wondered why we don't have it.
Lossless zooming is great as it preserves detail in zoomed situations while keeping the file size big, unlike 4k recording which would consume lots of storage to record then zoom afterwards
As our phone supports 4k recording, doesn't the G2 have the ability to have lossless zooming capability?
If so, can someone tell me if there is there an app that enables us to do this, or someone, perhaps xdabbeb, can enable it for us??
Thanks

Lossless zoom is achieved when u have an optical lens movment.
I dont believe any of these phones have optical zoom.
You can't "enable" optical zoom. It literally means that the lesnses need to move back and forth. Like in cameras. You see the lens moving and adjusting to the zoom.

I thought it was a software thing on mobile phones where they increased video resolution and cropped it to show the area you are zooming in on so that the zoomed part remains 1080p??
For example, a quarter of a 4k video would be a 'zoomed in' 1080p one

I guess.. It can't preserve detail so it has to be cropped.
It's like zooming into a picture in photoshop.
We have digital zoom only. Digital zoom scales an area up to "zoom" in. It blows up pictures making them look nasty.
This is a great question and I think the prior replies have missed the concept. Yes, our camera is like 8 or 12 megapixels, but 1080p HD video is like only 2 megapixels. So when we record video on our 8 megapixel sensors, the sensor "line-skips" to resolve only a 2 megapixel (1080p) image. When we zoom in, digitally, it keeps the same "line-skipping" design as non-zoomed. This results in a lower-than-HD resolution. It would be VERY SMART to adjust the line-skipping design, or not line-skip at all, on a digital zoom, thus still using 2 megapixels worth of photo sites to capture the "zoomed" image. This is the same concept as "sensor windowing" used on RED cameras when changing the resolution. I'm surprised this is not the new/standard way to implement digital zooming on ALL modern smartphones to preserve details and resolution when digitally zooming, because of course there is no optical zoom option.

I am quite sure the note 4 does not have optical zooming. This is the reason it made me think and 'come up' with this idea.

I do not know much of cameras so I do not fully understand what you(Jackdup) are saying, but I think you know what I mean
Just wondering, do you know of any apps that can do this, or know how this works? Maybe you can explain it to a developer to implement it in our devices
Thanks

Hey there
I got my Desire HD now for 2 days, and I love it.
The recording of videos is beautiful, but I am dissapointed about one thing.
When you record in 480x800 resolution, you can use a very nice zoombar, and it works great.
But when I want to record in HD with 720p, I cannot zoom anymore...
Why is this..., and is there maybe a way to enable the zoom with 720p?
Sorry but you clearly dont understand zoom, the maximum definition of the camera is 720p, without an optical zoom i.e. a big lens there is no way to zoom in and maintain 720p.
Software zoom works by enlarging the picture - using less definition. So there will never be able to do this while maintaining 720p.

I knew this, but why is it not possible to enlage the picture with 720p?
because it would be misleading?
If you had a setting for 720p, and say you zoomed in by just 25% your almost back to Standard definition.
so why not just film in normal definition in the first place?

So what... if I film with normal definition and use the zoom, the quality will drop either.
When I film in 720, it has a bigger resolution, I would like to zoom in a bigger resolution, but yea... maybe HTC does not have enough experience with cameras yet (so far I heard).
Anyways, I like the camera either, but I'm just dissapointed that I'm not able to zoom in 720p mode.
If you film at normal definition (under 720p), you will have sharper digital zoom, because the camera is more sensitive and has lot pixels left "to zoom with". It is hard to explain, but trust me, zooming at normal definition is possible without losing so much quality.

Thats where we need clarrification from HTC..
How do you know that when you zoom in standard resolution the it doesn't do it by using the full resolution and zooming in on that part, thus maintaing the full 480p and that section you have zoomed in on?
I would sugest this is the case - have you tried it?

I was trying to put it in simplistic terms... sorry
imagine if you had 720 lines, you can move yourself so close you can only see 480.
Well this works in reverse if you only want 480 lines and you zoom in, in effect your selecting the middle 480 lines of the total 720. so you should not see any loss in quality, unless you are really zooming all the way in.
any better?

Anyeone disappointed with the SGS2 camera? Its ok with normal photos, but then when you try zooming it, the photos look atrocious! its all grainy and no detail at all! is there a fix for this? I have disabled touchwiz and am using ADW...
I didnt seem to have this problem on my nexus one..
I dont see a point of using digital zoom in SGS2 or any other similar phone. It just cripples image quality, nothing else. Personaly I have never used it. And no. Im not dissapointed, Im quite impressed by the built in camera and its recording capabilities. If you wanted to zoom that much, you should have bought standalone camera with optical zoom. Phone is still phone you know.

Optical zoom is the only good zoom. My tz10 has 12x optical and digital. Even if it had no optical you wouldn't switch digital zoom on as it just pixelates the image.
I'd be impressed if I was shown a camera that didn't ruin the picture with dz

I think up to 2x digital zoom, the photo quality is still usable. Note: more higher ISO value, you will get more grainy & less detail photo. The digital zoom may only apply for low ISO setting only
I think the picture quality of the SGS2 is extremely good for a smart phone, after 2 weeks of use.
It's better than many real cameras i know of, which I wont cite (as fanboi wars aren't all that interesting )
if you zoom zoom and zoom all cameras will show grain. the grain it shows is always different and the one of the sgs2 is actually pretty good. I know many professional photographs who actually zoom like that and if they can't zoom as far as their 12MP camera they say it's poorer quality. That's just poor judgement (specially when its their job...).
Of course the resolution of 8MP is lower than 12MP for example, but resolution != quality. Zooming for such pics is also utterly pointless, unless you plan to print a huge poster from your phone camera shots.. but even then, 8MP isn't all that bad.
For everything else, theres huge 2000E+ DSLRs.

I know there is no optical image stabilization but what software stabilization ? Its more handy for video than stills for my use.
It is using optic-flow-based image stabilization
That is about all I know.
I don't understand the hype with optical image stabilization. The Note 5 has it, and it's so bad that it makes video recording almost unusable. Basically it creates this really nasty motion-rocking effect that distorts the video, ruining the shot.
Optical image stabilization should stay in DSLRs where the lens is decently sized.
I really hope the Nexus 6P does not include it, or if they do make a toggle to turn it off for video.

I think it's been shown that it helps with night shots. Less blurriness.
I've been using the Galaxy S8 Plus until I received my solar red U11 yesterday (glad I waited, it's very nice looking). Anyway, I am very impressed with the photo image quality of the phone (it is very comparable to the S8), but I have a few nitpicks about the video recording:
1) No 1080p/60 mode. I really don't understand why it doesn't have a 60fps mode when even phones from 2016 had it? It has 1080p/30 and 1080p/120 (for slow motion), so why no 1080/60? Is it overheating concern?
2) No way to turn of EIS in 1080p video recording mode? While 1080p is very stable due to its combined OIS and EIS, it also crops the view significantly when recording video in this mode (compare it to 4k, which is quite a bit wider but has no EIS). Anyway, the EIS is nice if you want that, but I think there needs to be a toggle or option to turn off EIS and have the wide recording mode in 1080p that is like the 4k mode. As it stands, there does not appear to be a way to change this.
3) 6 minute recording limit in 4k. I guess it's also due to overheating concerns, but why not just make it unlimited and have the phone's temperature monitoring stop recording automatically if it gets to a certain temp? Some people are reporting overheating stoppages even before the 6 minutes, but in cooler environments, we may be able to record indefinitely in 4k.
Things I DO like about the U11's camera though...
1) Photo app and quality are excellent. Nice Pro mode too.
2) Glad I can lock exposure and focus during video recording very easily.
3) Focusing pulling with the touch screen is very nice on the U11 (it doesn't rock back and forth when focusing like many other phone cameras).
4) Audio recording options are very nice (3d audio vs hi-res, and acoustic focus)

Thanks! It's good to see that they are working on adding 1080p/60, though it appears to be a ways off.
Another thing that bothers me (when compared to the S8 or iPhone 7) is that I can't seem to take a photo while recording in 4k. I'm not sure if that's a software or hardware limitation, but I used that all the time on those phones. I really like using the squeeze to open the camera, take a photo, and switch between front and rear cameras though!

Try Open Camera on XDA, it works shooting 1080P without EIS and no time length limitation on 4K.
I've also see the same issue on the HTC 10 in regards to the 4k and taking a photo while recording if you can call it an issue. I suppose no one had complained about it and they left it unchanged

It's a nice camera app, thanks. Tried various settings in the app for video recording. Looks like no matter what framerate you choose, it can't go above 30fps. I thought maybe it would let me shoot 1080p/60, but nope (even when setting it to 60fps, it still records at 30). Also doesn't seem to be a way to take a photo while shooting video in this app? Nice that you can shoot longer than 6 minutes in 4k though (I didn't try it yet, but I assume it works).

I call it an "issue" only because I have come to expect it when shooting video now. In fact, I used it quite frequently on my iPhone and Galaxy S8. Being able to take a photo without interrupting the video recording is a pretty important feature, in my opinion. I suppose one could load up the video in software and capture a frame manually, but it's a feature that other flagships have, so I miss it.

Indeed, my old year 2012 HTC One S supported shooting FHD video and taking a real photo at the same time and I owned a Galaxy S6 support that feature too. However, I think during 4K recording that no phone could take a real photo, all they do is just capture a frame from video clip and pretend that is a photo.

Right, I understand it's not an actual "photo" at the highest resolution, but I would still like the convenience of capturing a frame during 4k video recording like I can on all of the other flagships phones.
Wow I'm glad I found this post, I thought I was going crazy with the issues you mentioned, especially the cropped 1080p video! I hope they can fix that with the 60fps update, because it is really annoying.

1080p60 is being introduced in stock ROMs with versions 1.26 and higher.
Do you know if EIS for 4k video is planned? Thinking about buying the U11 instead of the much too expensive Pixel 2, but the lack of EIS in this case is a bit of a bummer.
Is it possible to record a video using a wider angle like the one used for photos? Videos are always zoomed in on the stock camera app or Gcam. Although Short videos have a slight wider angle it only allows 15 second videos. Is there any away to change that?

So GCam is great at everything photo-related on this phone, but its video output is not impressive except for the 4K option.
You should stick with the stock camera for video recording as it does a great job using EIS.
If you want a wider view, disable stabilization in the stock camera or record at 60 fps.
If you want the widest possible field of view, use Open Camera, disable stabilization, and set the video resolution to a 4:3 ratio. That will use the image from the entire sensor

Thanks for the help! One strange thing is that on Open Camera setting a video resolution to a 4:3 ratio (video stabilization disabled) allows a wider view. On the stock camera even when disabling image stabilization/1080p60 it won't use a wider angle, unless you compare to 1080p30, which has a closer angle than 1080p60. Any ideas what could it be? There's no option on Video Settings on the Stock Camera to set a 4:3 ratio.

That's fully expected as the digital video recording standard nowadays is to record in 16:9 widescreen. I haven't seen any newer phone whose stock camera app offers anything but widescreen resolutions. Some will have the option to record in the screen's resolution and/or ratio.
So, when you're talking 1080p, it is understood that it's 1920x1080, which is a 16:9 ratio.
The sensor produces a 4:3 image, but in video mode the image is by default cropped to 16:9 – the top and bottom of the image are cut off, making the vertical field of view narrower. You have to use a third-party app to enable the sensor's ability to record 4:3 video since this is non-standard. But for typical purposes, I don't know why you would do that, although you can, if you need your camera to capture as much of the environment as possible All our screens are (ultra) widescreen though, and it's more comfortable seeing widescreen video on them.
Electronic image stabilization further messes with the field of view. It 'reserves' a margin on all four sides of the image and uses gyroscope data to move the image back and forth within the frame, compensating for the movement of your hand, and giving the appearance of a more steadily held camera than it actually was. Further software trickery may be/is involved. The final result is that of a 'zoomed in' image. That's also the impression that you might get from the difference between a 4:3 and a 16:9 cropped image from the same sensor.
