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.
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?
What is the difference between these two sensors IMX682 vs IMX686?
Same differences from the imx482 and imx486
The more basic sensor can't record in 4k 60fps, but thats it, same sensor, doesn't even make a differente to phones that can't record 4k 60
I was looking through the video quality settings on my A71 and there doesn't seem to be a 4K 60fps option. If i'm not mistaken, the 765g is capable of 4k 60 and I know the camera hardware surely does so what's up with that?
I always used Gcam for photography and videos because it enhances photos and stabilize videos but the most important feature for me was recording 4K videos at 60 fps, originally the MIUI cam can't record at that fps but somehow
Gor the Gcam it's possible. Today i just switched to a custom ROM wich is Corvus OS, i installed Gcam but i was surprised it can't record at 60 fps cuz it's showing error.
It's 89% something related to software a.k.a the custom rom, becs when i switch to the stock rom, the [email protected] is working perfectly.
Anyone has an idea about this, is it possible to enable 4K @60fps without switching to Stock ROM ?

It's because of sensor, not software. IMX 682 sensor supports maximum 4K 30fps & it's slightly worse version than IMX 686 sensor which supports 4K 60fps.
That means that it's hardware issue, not software.

So how tf i was able to record at 60fps on 4K when I was on MIUI ?
And i even did a fps meter test ro check and it was between 58_59 fps

Thats weird, that was what i thought until i saw these phones specs.
Realme GT
Realme X7 Max
ZTE Axon 30
Xiaomi Mi 10T
All say they use the IMX 682 and all support 4K/60
So what is going on here? Is it the sensor? Is it the soc? Is it just marketing? Did some manage to overcome the harware limitations?
Assuming the sony specs are true. The only thing i can think of is :
a) If imx682 its capable for 1080p /120 then theoretically it could record 2k/60? and then use an upscale trick or something?
b) Using a trick in realtime or in post-process to convert 30 to 60fps with a fast soc (MEMC style)
(i don't know if or how how pixel binning can be applied in video recording so i'm leaving this out)
I have so many questions
EDIT: there is a discussion about the IMX582/586 here https://forum.xda-developers.com/t/4k-60fps-with-gcam.4265067/

4K and 60 FPS works in GCam in Custom ROMs.

Have you verified with MediaInfo that it's 60fps? Because I can select that too but it still outputs 4k 30fps.

In the time of the posting I thought like that, but still, POCO F3 with IMX582 can record 4k 60fps with Gcam, but it has some micro stuttering. Which also could mean that sensor is not fully capable of it. It can be the same case here.

You are absolutely right, sorry.
Recording doesn't start when I select 4K and 60 FPS

So i guess it kinda works if your SOC is able to handle 4k60

S870 can handle it, so it's not because of that. Camera sensor probably misses the buffer power to deliver 100% smooth 4k 60fps. But it's better still than 30fps.

Yes i mean it works with some dropped frames but you also need a SOC that can do it. I have seen that Poco X3 Pro can do it but on Poco X3 with 732G it seems a no go because of the SOC limitation.
Sorry for my bad English.
