Hey all,
Here's a pretty cool macro DSLR effect I discovered the other day. FINALLY a use for 4K video resolution!
All you have to do when in video mode is select 4k (3840 × 2160) and zoom in 4x. When close to a subject tap to focus as usual and you may be shocked that the image suddenly has crazy depth of field but still remains sharp.
The reason? The camera module has an aperture of f/2.2 which is great, but that's not the real clincher. 4K UHD has 8,294,400 pixels in a frame. Just to give you an idea 1080p is only 2,073,600 pixels. So basically, when you zoom in 4x, your image still looks great. No other phone camera can do this in 2013.
Big deal, SO WHAT? you may be thinking. Well the results CLEARLY speak for themselves..
Happy shooting!

Are you saying that if you record in 1080p mode and framed the shot exactly the same, that the depth of field would not be the same? I'm confused?
I understand the merits of 4K recording, but I don't see how the depth of field would be affected.
WOW! Cant believe all that comes from the small lens sensor of Note 3

I probably should have explained this better but you can't really frame the same shot in 1080p because you'd be way too close to the subject for the camera to even attempt to focus on it. 4k allows much more flexibility for macro shots.
And do you have a 4K display to see this awesomeness?
Otherwise you're just watching it at 1080p lol.

Now I'm curious how 4K video zoomed in 4x downscaled to 1080p compares to 1080p video zoomed in 4x. I wonder if Samsung is using software zooming to enlarge the video image or cropping the sensor to achieve the field of view. If it's software zoom then there's obviously going to be a loss in quality. But if it's simply cropping the sensor there should be no difference. And it fact it'd be a waste of time and memory space to shoot in 4k zoomed to 4x and then having to downscale it to 1080p afterwards. That would add unnecessary steps for editing. Also, in 1080p mode you have access to the software video stabilization while in 4k mode you don't.
it's not about the resolution lol. think putting on different DSLR lenses for your phone.
great find, OP! will be trying this soon
4k works with approx 50% more colours than normal 1080p. Even if you dont have a tv to warch it in full res, a 4k clip will look and FEEL rather different than everything else.
The clip in the above link is done with a little bit of postproduction. Indeed its impressing and there is more to be discovered.

lol, it's not about the resolution. it's kinda like being able to use different lenses for your note 3.

Cropping a sensor of say a 35mm legs by 1.6 doesn't give you a 56mm zoom perspective. You're still getting a relatively wide angle shot but simply cropped.

I understand that. However, in this instance is 1080p mode on the Note 3 simply cropping the sensor to begin with? My question in relation to the OP is if you shoot at 4K mode, zoom in a 4X, is the phone simply cropping the sensor 4x to give you a lossless zoom? Or it is using some type of software pixel binning to give you the zoomed in view? Or perhaps a combination of both.
And how does that compare to shooting in 1080p mode with the 4x zoom?
I took a few sample videos sitting at my desk and to my naked eye viewing both videos on the Note 3's screen, there is 0 difference between shooting at 4K resolution with a 4x zoom and shooting at 1080p at 4x zoom other than the file size. The field of view is identical. I'm looking to see if there's any advantage at the end of the day if I want to end up with a 1080p file as the end product. Is there any advantage to shooting the same field of view at 4K and downscaling?
The 4x zoom when shooting at 4K did not give me a distance advantage versus shooting 1080p at 4x zoom. The phone remained at the same distance as my subject when framing the shot with the same field of view. So for macro video shots, I do not appear to have any advantage when shooting at 4K.
Epic and very well done video!

I think what he's saying is that no matter of 1080p or 4k, distance and senzor pixels are the same, therefore theoretically you shouldn't necessarily have to do 4k to do such zooming. Question is: in effect does zooming in 1080p still record lossless as far as the sensor goes (13mil pixels), or zooming in 1080p only zooms into the 1080p capture (magnifies the 2mil pixels).

I just assumed that zooming in ALWAYS "magnified" the pixels so you'd naturally just get sharper detail with the 4k mode. I now understand my error with the field of view though (I tried it out myself too)
I guess the main thing to take home is the amount of detail you're getting from this phone's sensor.
hello guys
Can you please tell me wish phone is the best in term of camera? cause i want to buy one of them! thank you!

Z2 cam:
20.7 MP 1/2.3-inch Exmor RS for mobile CMOS sensor
F2.0 lens
4K video recording (3840×2160 pixels/30p)
HDR video
2.2 MP front camera
S4 cam:
13 MP / backside-illuminated CMOS sensor
F2.0 lens
FullHD video recording (1920×1080 pixels/30p)
HDR video
2.0 MP front camera
All in all the Z2's cam should provide a better camera experience
but i heard that the z2 camera struggles indoor is that true?

The S4 will probably take more eye-pleasing pics, despite the lower MP. Samsung has always had great photo processing software. All cameras struggle indoors when there's less light (and outdoors when darker too). I doubt you'd be disappointed in the Z2's camera though, but it might take some tinkering and experimenting with different modes to find what works best. Beyond the camera, the Z2 is the better overall phone; faster processor, more RAM, waterproof, front-facing speakers, longer battery life (although the S4's is replaceable) etc.
If you're looking for an expensive 1-2 generation old flagship and camera quality is your priority, the LG G2 trumps both the S4 and the Z2.
Hi,
I want to buy a P20, however I'm curios if the main camera has OIS. Gsmarena says it does, however other sites don't mention anything.
So, does it or does it not ?
Thanks !
i doubt that. in movies mode there is only EIS.

False. 1080 30fps and all still photos are optically stabilized.
1080 60fps has Electronic Stabilization. 4k has none.

go to 1080p 30fps (stabilisation) mode and than change to 1080p 60fps (no stabilisation) you will se that in 30fps you see less on the screen because the phone is making crop for the EIS stabilisation. if there were an OIS the frame in 30fps and in 60fps should be the same.

Check out any disassembly video, you will see the cameras have OIS. They physically move.
You see less of the screen because it crops from a 4:3 format in photo mode, to a 16:9 format in video.

Ok if you have seen the module thats ok.
I'm seeing the crop change switching between the video modes.
See my post here if anyone is interested in higher resolution EIS on the p20. Works on mine at 3k resolution.
https://forum.xda-developers.com/hu...resolution-t3776382/post76617559#post76617559
I do not think the camera has OIS, or it has OIS but it is not enabled.
Looking with a flashlight in an iphone 7 camera, I can see the lens moving to compensate for the shakiness, however looking with a flashlight in the Huawei's lens, I cannot see the camera move in any direction ... So, no OIS here
I think it has AIS which is digitally stabilised by the AI.
Strange is that the iphone 7 only uses OIS for video ... If I switch to photo, the lens stops moving ...
There is no teardown video for the P20 which shows the camera module's inner parts moving. Can anyone confirm the OIS with any evidence? I think it might be there, but not enabled for sure.
Do any phones exist that can shoot true 4k video (3840 × 2160) from their front camera? even flagships such as the Samsung Galaxy S9+ seem to only shoot at 1440p for the front camera.

The Samsung S9+ is about as good as it gets for front camera, looks like you did your research but tech evolves everyday.
So I got my Xiaomi mi 10 ultra and I love it.
But what I don't understand is that sensor under the telephoto 5x lens.
It is an Sony IMX586 which is a pretty decent Sensor. I am happy with the picture quality so far.
But video.. something weird is going on here:
In xiaomis camera App i was not able to make 4k or 1080p 60 fps videos with the 5x tele.. the smaller, not as good sensor of the ultra wide (12mp got no more specific info) is capable of 1080p60.
The IMX586 is a good sensor. Other phones are using 4k 60fps with it. Even a new Drone got the sensor and is capable of 4k90fps.
Why is xiaomi not letting me film in 60fps 4k or 1080p?
Is there a way to get this work in gcam or ultracvm?
