hello guys ,i want to ask if someone can explain this to me.
Nexus 4 records videos at 1080p in mpeg4 with 12Mbps
Movies we download etc are 1080p in mkv with 3-6 Mbps
The question is why do movies in mkv look so much better ??..is it a compression/container issue ?
Thanks !
Because the camera is crap..IMO.

besides that looking at the info from the 2 videos, theoretically nexus recordings must look better.
but i'm pretty sure i'm missing something significant in this comparison that's why i asked if someone who has more knowledge on this, can give me an explanation ...
The camera lens, and light sensors are no where near the quality of Hollywood cameras. The bitrate supports the quality but the camera can never deliver it. Its like the megapixel fight with still cameras. A 3 megapixel camera with a great lens and iso sensor can completely blow away a compact 14 megapixel camera with only so so hardware.

thanks man ! i guess we can blame the crappy lens for this one ...i think this explains why s3 or htc one x videos are looking way better despite having a lower bit rate than nexus 4 videos ....
Exactly the lens and camera sensor quality is more important than the pixel account. I saw to many cheap 14 mega pixel cameras pictures that are worst than good 3 mega pixel pictures took with good old cameras. My Nexus 4 doesn't beat my old Pantech Element pictures...On the PC you see the differences.

You cant compare. Such type of compare is irrelevant.
Movies are captured with professional cameras like RedOne at 4k resolution without heavy compression in raw format, further being processed and compressed by professional encoding softwares and so on...
Nexus 4 uses commercial consumer compression algorithm on the way, thus the output result is obviously worse.
That's is one of the major differences.
Hi all
The 4k camera of the Note 3 seems to be quite impressive. I'm actually thinking about buying the Sony RX100 II camera for travelling, but I'm unsure whether it is worth it. Since compact digital cameras don't support 4k yet I would just buy yesterday's technology.
What do you guys think, does it make sense to buy a compact digital camera at the moment despite of already owning a Note 3? Or is it better to wait for 4k digital cameras?
Thanks in advance for all inputs.
Depends on the price. The Note 3 camera is downright horrible in low-light, fluorescent light and with motion.
I'm a Canon-person (Technically I'm a DSLR user), so I can't say how good that Sony camera is. But the Note 3 camera is only good in bright sunlight, so it's probably a good idea to buy an additional camera anyway if you travel a lot.
As for 4K, that's only VIDEOS. You'd be hard pressed to find a digital compact camera these days with a resolution that low. For photographs, 4K is low: 3840 × 2160, 8.3MP. Anything above 8.3MP is a higher resolution than 4K, but only on STILL SHOTS.
I have both (as well as Canon dslrs) and the Sony blows away the GN3 for image quality.
I have both as well and the Sony RX100ii blows the Note 3 away especially in low lighting. I basically use to take spur of the moment pics. If at an event, party, or on a trip I would definitley use the RX100ii instead.

rx100ii is amazing, but it won't pair with the note 3, so it's slickest feature of using the phone as a remote viewfinder won't work
Have you tried the Sony software? Works great on my Note 10.1

If I understood him right, he's talking about video recording. A FHD is only 2K (not quite but very close), the 4K video on Note 3 is double that and there's no compacts able to record 4K video as of yet. Excluding a GoPro Black edition (which is around $400 +/- now) that records 4K @ 15fps, 4K camcorders start from around couple of thousand $$$.
4K video is a new tech and not standardized yet, so hold your horses - the video industry may decide to go another way, like it happened in a battle between BD and HD-DVD. Besides there aren't many TVs yet supporting anything higher than a FHD plus they're expensive.
Wait for this tech to mature a bit and it will also get cheaper. In the main time the 4K video on Note 3 will do the job (stock on microSD cards!)
If OP's question was whether to get a compact for stills - they the answer is yes - no phone can compete with a good compact camera and RX100 II is more than a good compact.
I'm a Sony shooter but I don't own the RX100 MkII, I DO, however, have a Canon shooter friend that owns the RX100 (1st version) and he absolutely LOVES his RX100. If you want something pocket-able then, you will NOT regret the purchase... but if you don't mind something slightly bigger, I highly recommend the NEX-5T... it literally does better in high ISOs than a lot of DSLRs out there (and the amazing thing is, while it's pretty compact, it sports an APS-C sensor!!)
i am facing issue with hdr10+ recording with rear camera.
i selected hdr10+ option in camera settings with low resolution but when i tried to make video with hdr10+ with rear camera there is no written hdr on on the s10 camera screen while when i make video with front cam it says HDR ON
on the camera screen.
can anybody help me how can i make hdr10+ video with rear camera?
I dont think HDR+ can be recorded in low res. I think it has to be the 4k or at least 1080p
Your friends are never going to believe what you did. The only way to prove it to them is with that video you took. Rate this thread to express how videos shot on the Xiaomi Mi 10 come out. A higher rating indicates that videos are smooth (and not choppy) and that auto-focus works very well, and that the camera adjusts quickly to different lighting conditions while recording.
Then, drop a comment if you have anything to add!
I have never seen better video recordings than on the Mi 10 so far. 4K @60 fps is gorgeous in terms of sharpness, colors & artifact handling.
The video bitrate @4K is at 38 Mbps.
At 8K it has insane 104 Mbps.
The stabilisation is also remarkable.
I wonder what the Samsung S20 devices are capable of?

At the moment I only have the Mi 10 at home.
When my Pro has arrived I will definitely try it out

Question to Mi 10 owners - how would you rate 4k60fps quality?
In some samples on youtube, I saw that 4k60 isn't fluid and drops some frames. The same it was on mi 8, but using gcam 4k60fps works quite well - much better than native cam app. Would be interesting to hear if somebody uses Filmic Pro / Mcpro24fps on Mi 10 to comment if there's some video quality increase and stability using 3rd party apps?

Video quality is actually one of the best I have ever seen on an android phone (iPhone is the king of video in my opinion) at least on the main sensor (the wide angle is very, very dark and it can't do 4k60 on native camera, only 4k30 or 1080p60) . I'm on Miui.eu beta and, at least for me, 4K60 is very fluid. But is important to say we don't have electronic image stabilization at 60fps (at any resolution) so the video is gonna be a little shaky using only optical stabilization.
Filmic pro is incapable of using the wide angle or the macro lenses, only the main one (mi9 can use all of them with the last updates of Filmic Pro), but it can do 4k60 and 1080p120. You can enable OIS, EIS or even EIS+OIS on Filmic, but EIS seems to be doing nothing actually even if you enable it. Apparently it does not works yet. I appreciate the manual controls Filmic gives you, but since Mi10 already have a manual mode for video and other advanced options like a very good LOG mode, the only real benefit of using filmic is the higher bitrate, except if you want really manual precise controls.
Feel free to ask any other question. Hope I helped.

Thanks xLeonix,
Glad for your answer!
Interesting to know about the sensors availability on Filmic Pro. For Mi Note 10, I send request to devs through the app: information -> version x.xx.x (click) -> and press contact us (after that you will be guided to email, the app will generate metadata.json file and please write to FilmicPro devs to look up for possibility of enabling additional sensors. Thanks to Filmic Pro team they helped me and with latest update gave additional (ultrawide/tele) sensors option to use with Filmic Pro. Hope this would be with Mi 10's ultrawide camera too!
For 1080p/60 and 4K60, have you tried to enable electronic stabilisation through GCAM app (urnyx and burial mods)? On my wife's Mi 8 4K60 works stabilised with OIS/EIS via gcam. EIS works interestingly, but if there's not much camera movement, I would say the quality is fine. Also can use much higher bitrate without loss of quality (native camera's app bitrate is equal for 30/60fps).
Also would be interesting to see a comment from a person, who also tried the mcpro24fps on Mi 10 - does it let to use ultrawide camera, and availability of 4K60.

Answering your questions, yeah, I have tried a couple Gcam mods for photo and video (specially for night sight on front facing and ultra wide lenses, since Mi10 doesn't let you use might mode on front facing camera. It didn't let you use it on ultra wide neither, but xiaomi added night mode on ultra wide with an update).
At the moment, I have installed Urnyx and Nikita gcam mods. Urnyx surprisingly let me record 4K60 on the ultra wide (can't do that on native camera) but with no stabilization of any kind. And it freezes if I try to enable 60fps on the main sensor. Nikita let me actually use the main sensor at 4K 60 with EIS but it isn't even half as good as the native one, It's only a little better than using OIS only. Nikita by the way freezes when I try to use ultra wide sensor.
About mcpro24fps, there's not much to say. It can do 4k 30 on the main camera with OIS, EIS or both OIS+EIS. It can do 1080p120fps too, but for some reason it won't let me do 4K60 in any way on main camera. Mcpro24fps can use wide angle and macro lenses without any problem, but it can't do 4K60 on ultra wide, only 4k30 . Surprisingly mcpro24fps let me set the ultra wide sensor to 120fps at 720p, but it is really noisy (unusable) and the field of view seems to be cropped so it almost match the main sensor. So there's no use for it. It can also do 720p 120fps on the front camera. That's all I can say about mcpro24fps based on my testing.
If you have any other question, feel free to ask. Hope I helped!

That was really helpful, thanks xLeonix. Quite surprised to see you use all the video recording apps as well!
Interesting that with Urnyx you can record with ultrawide! Nice!
By the way, they just added support for the Macro and Ultra wide lenses on Filmic Pro's lastest update.
Okay, I understand (what many others don't) that although the S20+ is listed as a 3X-30X zoom, the actual optical zoom is 1.08 so the focal length of the actual lens is basically the same as the non-zoom camera. This is unlike say the S10 5G which the actual lens of the camera is 2X. However Samsung makes up for this by using a 64MP sensor. This basically results in as good or better zoom shots up to about 5X zoom than a phone with a tele-camera with a 2X or 3X optical zoom lens but only a 12MP or 16MP sensor.
This is a bit astonishing considering the number of pixels decreased by the zoom factor squared when using digital zoom. So, the lowest zoom of the tele lens on the S20+ at 3X is essentially a 7MP sensor. 3 squared is 9. 64MP divided by 9 is 7.1MP. Compared to say the S10 5G which has a 2X optical zoom and 12MP sensor. So a 3X zoom for the S10 5G is a 1.5X digital zoom of the 2X optical. 1.5 squared = 2.25. 12MP/2.25 = 5.3MP. So you can see how the S20+ can keep up with other cameras with 2X or 3X optical zoom but only 12MP sensors. It's notable though that with 2X zoom, a camera with a 12MP sensor and a 2X optical zoom has a higher resolution image than the S20+ at 2X zoom since the S20+ doesn't have an optical zoom lens.
What's more interesting is the 64MP sensor on the S20+ has a 0.8um pixel pitch which means the sensor is roughly 9,500 pixels by 7,150. So at 3X zoom the sensor output is going to be digitally cropped to around 3,160 x 2,380. However no matter what zoom resolution you use, Samsung outputs a 4032x3024 size image, basically "faking" the resolution for all images taken at anything over 1X zoom. The file size goes down as the zoom goes up even though the image resolution stays at 4032x3024 because the JPEG compression algorithm basically can see it's a fake resolution (essentially a lower resolution source image interpolated up to a higher resolution.)
I'm not sure why manufacturers do this except for only from a customer satisfaction perspective as people would be complaining why their 10X zoom images are only 950 x 715 pixels. Yes, S20+ users, that is roughly the true resolution of a 10X zoom image from your phone. But consider on a 12MP sensor with 1X optical lens, that true cropped resolution is closer to 400x300!
The bottom line is the S20+ Tele Camera is basically equivalent in resolution to a phone with a 12MP camera with a 2.5X optical zoom because it's not actually an optical zoom lens. So Samsung's advertising it as a 3X "hybrid optic zoom" isn't a total lie, but 2.5x would be closer to accurate as far as the equivalent of an optical zoom on a 12MP sensor.
In reviewing tests images, to get the best images on this camera you just want to use one of the 3 cameras without manually zooming in. If you do zoom in on the tele camera, try to not go above 5X.
And no true optical zoom = no depth compression and distorted perspectives. Portraits look like crap. Fisheye effect still there, only mitigated by the fact that only the central part of the view is kept. For real portrait you need a phone with a real 2x or 3x optical zoom lens. I should have known better before buying...

It's especially ridiculous considering the low-end S20 FE has 3X optical (although with only an 8MP sensor). I can only think the reason was to create more of a separation between the Plus and the Ultra to better justify the higher price of the Ultra with the 3X optical + 108MP sensor. They should have just put the 2X optical on it from last year's S10 5G instead of a ridiculous 1.08X.

I think the Ultra has a straight 5x zoom, like the P40 Pro. Useless for portrait (way too much zoom), so portraits are done on the main sensor with a crop to simulate a 2x zoom !
WTF !

We're both wrong, it's a 4X optical on the Ultra. I was confusing it with the 3x "hybrid optical" zoom spec on the plus. "Hybrid Optical?" that's just another label for "Forced Digital Zoom." At least on the Plus.

Samsung is not the only one, I just got myself a Sony Xperia 5 II, thinking the 3x zoom would make nice portraits, only to find out the quality was so bad it made me want to cry (900 euros). Upon searching for answers, I found out that it too is a crop, from a 20 mpx sensor this time...
At least if you get an iphone you have true zoom... I'm tempted. But boy do I hate iOS.
AFAIKl, the zoom lenses are used when the light conditions are optimal, also have an iphone and i can assure you, it also uses crop when the scene is underlit. So you are not missing on anything. But i can say, camera's on smartphone still suck (personal opinion: i use mirrorless for photography).

Yes, I have an APS-C sensor camera for when I'm *planning* to take photos of important events, on trips, etc and I don't mind carrying it around (although it is jacket pocketable because it's an APS-C platform.) The problem is, in the practical reality of life, some of the best shots are very sporadic and unplanned and most people don't carry around their DSLR with them everywhere they go all day long like a woman carries a purse. I take way more photos on my phone than my camera because I always have it with me. So why not go for the best available, within your budget.
But yes, there is a whole younger generation that wouldn't even consider buying a digital camera anymore (except if they were going into the photography profession) as the camera's on their phones are more than adequate for snap shots they are just going to post on instagram, send via MMS, add it as a wallpaper or screensaver, or include in a Blog post and *maybe* print a 5x7 of.
The reason for their decision to do this might be to enable 8K video recording as the 8K functionality uses the 48mpx sensor.

That explains why the Ultra has a real zoom, as it can use the 108mpx sensor for 8K...
So we lost the zoom quality for portraits of our loved ones for a gimmick which almost nobody will use...
What a shame.

I liked samsung, when they included ir blaster, heart rate sensor and all kind of weird af stuff.
Hated it when they removed expandable storage from s6 and note 5 series but after note 7. I feel that they are less likely to take risks and try to compete with 2nd class brands like oppo and vivo which only focuses on camera for consumers. (No offense to vivo as they also spend a lot on research which include the first for indisplay fingerprint scanner and 2k screens, but they only showcase that tech on mobile world congress).
And at that time, phones used to be fun, the price was relatively affordable $600 as compared to $1200.
There are phases of popularity of features like there was phase when companies are competing on who can produce the slimmest phone. But now the phase is related to camera's, before this, it was the user experience, which made samsung to ditch the TouchWiz and come up with one ui. I was there on touchwiz for s7 edge and one ui with s8.
Also, i dont know how tech reviewers are able to get the awesome photos using auto mode.
Out of 30 pics only 3-4 are good photos.
