[Q] Nexus 4 1080p Recording Vs 1080p Mkv - Nexus 4 Q&A, Help & Troubleshooting

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.

720p Recording on HD2 with Android

Well since Android is progressing well and they've started getting the camera working (I know this from HTC-Linux's Twitter) and since Android can actually play 720p as opposed to when Winmo is running it can't. And with the camera hack for the Nexus One that allowed it to record 720p I was just theorizing that there may be a possibility of recording 720p on HD2 while you're running Android? To me it would make sense but I know nothing of hardware specs vs software vs decoding speed vs screen resolution so I was curious as to what all other people reading this thread or Developers may have to say to this.
Bump...........
Indeed it would be nice to have HD recording on HD2, but you'll still have to take into consideration the fact that it is still early and lots of other bugs need to be fixed before such "luxurious" details can be looked over by the devs.
Not to mention the fact that the sound on the video recorder on the hd2 is bloody awful to say the least. I used to have an n95 and that wiped the floor with the hd2. I would be more interested in better sound.
The HD2's photo quality is limited by the lens, not the operating system on the phone. The N95 features a Carl Zeiss lens which enables it to take great pictures. Resolution is highly overrated when it comes to photo quality.

im not with you in this
see (dont forget to put it at high quality 480p on youtube for best quality)

one of the best videos i recorded
but i also want 720p
I know I may sound stupid and I'll accept peoples input if this does but I just think that if the Nexus One camera can get a hack to support 720p and the HD2 was relatively released in the same 3-4 month period (may seem long I know) it just makes me think that the HD2's camera should qualify for getting the same hack when running android and yes it does deal with winmo because HD2 can't run 720p videos normally through the Winmo OS but as demonstrated the Linux Kernel on HD2 was able to play a 720p HD video.
Just tried the new Desire V4 Build and it indeed has camera support so if any dev wants to look into it by all means.

Nah, I would bet it's the sensor more than anything.
I'm not talking about the pic quality, its the sound quality. It is very distorted and tinny. I was at a concert with my gf who recorded the same song on her average sony phone. The difference in the quality was shocking.
I actually think the video and picture performance are quite good, then again I came from a touch HD which was terrible. There is no hardware reason why this phone cannot do, in fact the hardware can defo record / decode HD but how easy it will be to get this to work in Andriod is anyones guess.
I am actually planning to keep this phone a while as IMHO it is still the best looking phone out there, the droids are too clunky and the samsungs are about 3 years behind in design.
I'm hoping we can get a full working full installable ROM soon so I can ditch winmo altogether.
Then again I only have 11 months left on my HD2 so something else may catch my eye - I dont think it will be winmo7 though as it looks dull as fnck.

yes the n95s lens was a zeiss, but that was just a name!
The lens was cheap thin glass, just like any other mobile phone lens ever made. There is a reason zeiss prime lenses go for £20k and upwards, I agree with you on that!
and your spot on about resolution being no way near as important as a good sized sensor, and good optics.
But one of the main reasons mobile phone video looks so crap, is the low resolution its always been recorded at! You look at some phones that can record 720 and it looks a damn sight better than the vga recordings, Mostly because It doesn't need to be stretched out and destroted like low res' video does
I definately haven't experienced problems with the mike for the HD2, I've recorded videos with my friends and they come out very well in reference to sound and there IS alot of sound in a concert so I wouldn't be surprised if audio you recorded at a concert would sound bad.

I always did wonder why the HD2's video quality only went up to VGA even though it has a WVGA screen, 0.o.

What im trying to point out is that lots of other (older, cheaper) phones record better sound. My missus used a w995 and It is much better sound.
granted sound probably isnt the HD2's stongpoint but the video performance is comparable with other models. Yes it could be better but it will only get better though enabling it in Android.
Any update on the 720p on htc hd2 ??? I would pay the person 100 us dollars if they get the 720p recording on htc hd2 with android !!

lol! mine records in WVGA(800x480) and has the option to record 720p(1280x720) but when i try it camera shuts down.. so the best a can record is WVGA plus the frame rate seems to be a bit smoother than normal HD2 VGA recording

how does it have that option? and cant that just be a vid codec error?(which can be fixed)
Any news about 720p recording in android?Is a driver still in development? I would like to try wp7 only for the hd recording ability,seems good

Misinformation

Why are some people here misinforming saying that the Nexus S doesn't record in H?
quote form google:
Rear and front-facing cameras
The rear-facing 5 megapixel camera is capable of taking stunning pictures and HD videos that you can share with friends and family. The front-facing camera can take VGA quality images and video.
This is the Vibrant forum.
My concern level for what a camera on a phone that I don't own can and can't do is non existent.
I posted this here because it's here that I seen this misinformation when soe user are comparing the 2 phones.
Did it really need it's own thread?
While Engadget may be biased, they have comprehensive reviews.
Such a respectable blog would not have missed an obvious feature. 480p was the maximum resolution.
I'm not sure if it can or cannot, but I can see why they did omit that option (that the Nexus S cannot record in 720p).
It only comes with 16gb storage (while part of that 16gb is taken up by the OS and preinstalled apps, so its most likely less available) and only that. I would imagine 720p video would eat up that storage VERY quickly.

Well you just fell victim to false advertisement
Technically its capable just not out of the box
But yea why did you post here, whole thread over in NS general section
The highest it records is 720x480 this is not HD 1280x720 is
People see 720 and think HD which isn't the case...it will eventually support it
whether a developer adds it ....they did with the nexus one.
Or Google will....the hardware is more than capable obviously since its the same as the galaxy s line

Nexus 4 720p/1080p video samples...

I know the device isn't out just yet, but I was wondering if anyone has seen a sample of Nexus 4 camcorder yet? (Front & Back). I rely heavily on my cameras for work & for other reasons & not to bash the G-Nex, but the camera sensor on this device is a little underwhelming to say the least. I heard the camera hardware was based off of the AT&T 8mp Optimus G, but I'm not sure if that's an actual spitting image of what we can expect from the N4.
Any links or input would be greatly appreciated in advanced. Worst case scenario, 10 days isn't too far away!
Here you have some video samples:
Hope is what are you looking for :good:

Thanks sooo much for the quick reply with content. The actually image quality is quite an improvement, but my problem lies with the FPS & the audio to a certain extent. I wasn't expecting perfection, so I'm overall happy with what we have here. I'm sure it'll get better between camera mods & software updates. Thanks again.
The mic makes the video so crap, I tried to record video with my GS2 once upon a time and it was far worse than my old iPhone 4 which had such amazing audio quality. I mean I went to Reading last year and the iPhone 4 was super clear, picked up good bass and sounded great but the GS2 just sounded like I was rubbing a plastic bag over the mic and the bass just killed the mic all together.
So if the audio sucks then there is no point to it shooting video tbh. I just have a separate camera though so it doesn't bother me too much though.
I would love it if someone uploaded the original video file from the phone. Youtube seems to always use an aggressive compression on user uploads, I rarely see good 1080p videos on the site, even from pro cameras.
Make sure to go fullscreen when watching the video and turn your youtube video to 720p HD.
Can anyone help ....
I get HEAVY compression artifacts on the video recordings at 1080p on the nexus 4 itself - even when I upload to the PC. The sound and video is compressed sounding too.

Slow-Motion Capture

So I recently discovered that my wife's iPhone takes amazing slow-motion video. I've been doing some research and I'm not entirely sure that this is possible to do on the Nexus 5 because the frame rate on the iPhone slow-mo is 120fps and I'm not sure the N5's camera can actually do that. Is it possible? Are there apps that do this already? I am a volleyball coach and this would be extremely helpful. I've already tried the Coach's Eye App and while it is ok, it works with the standard video frame rate and thus produces video with lots of blur and choppiness. The functionality of the app is great but the video quality is lacking.
I think the N5 SoC is capable of 720p/120fps, but not sure the rest of the camera hardware can. If so, then maybe we'll see it in the future.

[Video Review] Xiaomi RedMi Note 2 with camera sample downloads

Hi all,
I've had my Xiaomi RedMi Note 2 for a while now and thought I would share my video review and hands on unboxing videos:
Unboxing:
Hands-on gaming, benchmarks, thoughts, opinions.
Overall this is definitely one of the best bang for you buck mobile phones around. The Mediatek 6795 Helio X10 runs great and the GPU is fastest enough for even the most demanding games. LTE/4G is crazy fast for me, I had never got 75mbps speeds before, not even on my LG G4. which caps at around 50mbps for me. The screen looks great and there isn't much to not like on this mobile. The 13MP camera is good in anything but low light and macros come out amazing (see my samples). What I find disappointing is the sound on video and in lower light the video frame rate drops below 30fps. Indoor low light shots are very average.
The phone has now been passed on to my wife and she loves it, complete overkill for her needs. MIUI also might not be for everyone. And the build is very plastic and cheap feeling compared to metal framed phones. I got it from GearBest here: http://www.gearbest.com/cell-phones/pp_229217.html
Day video sample (1080p):
Sunset (1080p):
Night video (1080p)
Camera samples:
Like on my Note 4 I get over 120 Mbit/s over LTE but Wifi, GPS and 2G/3G/4G is 2-3 times better than on my Note 4. Sometimes I can't belive this.

The foliage looks really washed out on those samples, was it windy or does it really do such a poor job? The rest of the samples seem really decent for the price.

It was windy and low light in some of the later shots. Low light pictures are not good at all.
I think that lack of optical stabilization makes video recording really bad. I think that the quality is descent, but the everything is kind of up and down all the time, a little cranky.....

Thanks mate. Can it does slower than this?
Nope. There's no other settings for slow mo.

Definitely I have a G4 and now a Note 5, I miss OIS, even DIS would help out here. The quality is good, but the audio is a bit washed out. But still for a $165 dollar mobile it's decent.
Hi,
could you test HEVC encoding capabilities for us, it's a little tricky, only "CINEMA FV5" app could support HEVC encoding for the moment, and if you can test [email protected] and [email protected] and Manual Focus as well it will be great, thanks in adavance
Very nice review and some of the only slow motion footage on youtube, thanks! :good:
