For downloading/encoding movies for viewing on the Sensation, what is the optimal resolution/format? For example, would 480p be sufficient or could I actually realize and appreciate a 720p/1080p quality movie on the device?
960*540 is the native resolution. The answer is pretty obvious then.
Obvious because 480p is underkill and 720p is overkill?
Therefore, encode your videos at 960 width.
So I found this video on youtube, a 4K video, where I can see it is very bad noise in low light, so I made a comparison with the raw footage and one I made after filters.
So What do you think?

This is from GSMArena's just-posted "mini review." So I think it's too early to think. If I were to think, I'd think of all the camera/video features whose performance I'd be concerned about 4K video recording/playback would be the least of them. Unless people have 4K monitors or TVs recording in 4K is pretty dumb. It's only going to be downscaled to the resolution of what it's being played back on. For videos to be shown on a 1080P mobile device, monitor, or TV content in their native resolution would look better. And 4K videos are absolutely huge.
Disclaimer: The following preview is based on a pre-production Galaxy Note 3 and by explicit request by Samsung we won't be posting any benchmark scores and evaluation of the Snapdragon 800's scores. We won't be conducting our usual suite of tests either. We'll leave those for a later occasion when we get a retail review sample.
Thanks for the info
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 the N5 takes pictures with an aspect ratio of 4:3, but the video aspect ration is 16:9. Is there anyway that anyone knows to get the N5 to take 16:9 photos?
Thank you in advance.
When shooting a photo in 16:9 the MP get reduced to "only" 9MP.
When i get the picture info from a G4 the info says 16mp.
So then MP's aren't reduced when shooting in 16:9 or 4:3.
Why is it that HTC does? Or is LG lying in the pic info.
The HTC u11's camera sensor is a native 4:3 sensor so if you take a 16:9 pic it will crop that 4:3 pic down to 16:9 which of course would reduce the number of total pixels because you are cropping the top and bottom of the pic. Same goes for other camera sensors that have a native 16:9 sensor. If you wanted a 4:3 pic it will crop the left and right sides, reducing the total number of pixels.

And what's wrong with a 9MP anyway ?

Did i say it's wrong? Can only imagine if you want a wall frame picture it can be difficult.

Thanks for the info.. So LG uses a 16:9 lens I guess.
I always take pics in 16:9.... So that's why I wanna know.
@*justintime* I found this article explaining very well : http://m.gsmarena.com/lg_g6_vs_lg_g5_quadcam_comparo-news-23636.php

Correct, the LG G4's sensor has a native 16:9 aspect ratio and the U11's sensor is a native 4:3 aspect ratio.
Regarding 9MP, have you ever watched any 4k content on a large screen 4k tv, like a 60 or maybe even larger?

Do you know how many MP's a photo has to be ti display stunningly on a large screen 4k TV, that is to look as great as a 4k content video?

I really don't know... You tell me? I am not a photographer.
I watch photos on TV 65" not 4K...and with the G4 it looks good to me.
Didn't test the U11 though...
