Nexus One steps up to 720p HD video

hey,

the nexus has the camera as the desire, or not?
so i think a port isn't impossible !?

This Threat in Desire Forum

The creator has stated that does not work on desire, but he will release a fix for it later tonight

Oooh, I think I'll be rooting very soon for this then!!

Judging by the quality of the sample video, its pretty clear why HTC never enabled 720p on these cameras, it just isnt real 720p, its just upscaling the already mediocre video quality of the camera to a higher resolution, which results in even more fragments and color distortion.
I seriously do not understand why people freak out because of this.

Post up video, before and after?
We could post up videos, before upscaling and after upscaling, that would be very interesting.

tbh, it's not exactly the reason I bought a Desire...it's a phone so as long as it can make calls and receive SMS messages it fulfills it's purpose IMO. Email, Internet, etc. are just bonuses

I guess if that is the video mode doing 720p it would annoy people as they said it would be included in a future update, so you would only expect it to be proper hd recording.

Not entirely sure about that. It's well known that the HTC cameras don't work very well in low light conditions and unless I've missed one, all the sample videos are taken indoors without a decent light source. I'm not saying you're wrong, it could very well be as you said. I'd just recommend withholding judgement until we've seen a sample taken under optimal conditions. It'd be great to have 720p even if it only works outdoors in blazing sunshine.

No phone will do decent hd video in doors in low light just doesn't happen, if you want that you need a high end hd cam corder.

its possible and being worked on but since it requires a kernel mod may take time BUT ... since we have the 2.32.9 kernel ported now it should easy to replicate

Maybe it is a bitrate problem?
Don't know if he increased it?

It would be nice to have the original recorded video to properly analyze it..if this whole 720p thing is some sort of upscale imho it is pretty useless..

Since the camera's (alleged) native resolution is 5 megapixels (ie. has way more than 720 lines), there is no theoretical need for upscaling (in fact you could go much higher than 720p without upscaling.
If the camera actually isn't 5 megapixel (and upscales photos to that resolution), then who knowsif it's worth it....

I think this is next step what dev guys will give us,supprise

Why would you get a smartphone just to make calls and send text. Plenty of decnt feature phones serve that purpose. Personally I don't use the camera on a phone and it's not a selling point. But beng able to hack my phone to take 720 video would be cool, even if I'm not going to use it. It's about the being able to and having fun. Also showing off to all my mates who have closed iToys! ;-)

720p is less than 1mp, so even if the camera were 1.3mp, it could still do 720p without upscaling.
5mp is more than twice as much as 1080p, the real limitation is processing power for encoding and storage space.

Well, while you are right in some ways, you are so wrong from a technical point of view. Capturing Video is a totally different story than taking photos because taking a picture with autofocus every 2-3 seconds, and capturing 25-30 pictures every second... you cannot compare that, so dont let yourself be blindfolded by megapixels. The size of the CCD elements, and the time theyre exposed to light PLUS the optics is what makes pictures/videos. And when you look at the size of those things in a mobile phone, you get the idea why smartphones are still miiiiiiles away from even midclass digital cameras...

it is all about processor man ,lenses has an effect ,but processor is the main

720p recording worthless? still pictures quality?

Im planning on getting the desire, and im REALLY interested in the 720p recording, but from the videos ive seen in youtube they look like like upscaled videos whats the bitrate ? 19-20 fps? also the audio sounds awful, kinda like the omnia hd back in the day
What about the pictures? i HATE the pics taken by my milestone, are the desire pics any better?

For video, the new radio has improved it. Its still not a strong point though.

The guy taking this one was trying to put it in some bad shooting situations (direct light, fast movement etc), so you can see what its like when not in ideal conditions.
For pictures, check out the awesome pics thread, it has some really nice ones.

720p video capture is unimpressive on the Desire. You need to be in a very well lit area for the videos to be barely passable. With inadequate light, frame rates plummet. This is a glaring weakness of the device. But fortunately, it isn't a primary concern for me and most other users.
Still captures are average at best. HTC was never known for superb cameras...

The camera itself in the phone is not too bad, its the android camera software that drags it down.

Yep, in good lighting 720p recording isn't bad at all, as you rightly say, for mobile.
My only complain is that they could have optimized a bit the codec datarate, especially since they provide you the phone with a class 2 sd card. However I must admit that I've tried to remove A2SD+ and my class 6 transcend turned out to be enough for avoiding stuttering, which occasionally happened before.
The complain mainly stems from the fact that AOSP roms don't have this problem.

Still pictures quality is adequate. If you're into editing your photos then they're quite amenable to post-processing. Videos, on the other hand... well you've heard it from the others already.

here's my first 720 test

Why do my 720p videos keep freezing for a second, every 4-5 seconds?

i have actually never had any issues with 720p recording on leodroid's rom. Frame rate is more than just good. As for the camera, its ten time better than droids.

Have you got A2SD or even worse, A2SD+ (dalvik cache to sd) ?
That can explain it, I think, along with some or a few background applications doing stuff while you record.
And, obviously, a slow sd card.

Not worth, I confirm that 720p is worthless on HTC Desire. Apparently the upgrade is software upscale. There is NOTHING difference in picture quality in video capture between 720p and 800X480 resolution. It's hardware suck and can't bring you any improvement in software. What a shame with "HD" recording in Desire.

Any proof?

There is another thread lying around where some tests indicate that, while 720p isn't HD for sure (nor is the ifonz one), there is a higher level of detail compared to 480.
There might be some upscaling or not, you might find it useful or not, but there is definitely some more quality in the image.

the problem seems to be the framerate and the SOUND, how can they screw it so bad? awful sound.
whats the problem with the sd card ? if i have a class 2 card for example ( 2 mbps) and the video is supossed to use 3 mbps what happens?

video recording quality

Hey guys, the camera seems pretty good on this phone when I'm taking pictures, however when I am taking videos it almost seems kind of grainy even though its suppose to be 1080p. Anyone else have the similar or different experiences? Please share!

Grain doesn't have much to do with resolution. What affects grain directly is light. Low light will give you more grain. Period. This is valid for professional cameras as well.
Shoot a video I good light and the quality is excellent.

Don't use 1080p it's crap and makes videos look awful. They decided to zoom the picture in about 40-60% and not allow you to zoom out. As a result everything looks grainy and out of focus.
Set ur camera to 720p look at how much you can see, how clear the image is how sharp the colors are etc and then switch to 1080p and you will find all the sudden you zoomed way in and can't zoom out and the picture quality dropped about 60%.
They claim 1080p support but it's a lie since they zoom in and give you a MUCH lower quality video than 720p does.

How do you switch to 720p mode?

I'm pretty sure that's just a big nasty bug. The camera sensor and chipset are all very capable of 1080. It seems like the 1080 is zoomed into the amount of area that 720 would take in the middle of a 1080 image...I won't say it's an honest mistake, as it's borderline retarded...but, if it is dumping 1080p worth of data it can certainly do 1080p video...that's only 2mp and the tough part is writing that to storage without it getting skippy...and clearly that can be done.
Though I am assuming it is writing a 1080p file...has anyone checked?

GoPro HD also does this. Few of my friend's digital point and shoots did this as well. So, it's a sensor issue, not a software one.
I posted this before:

Pardon my breathing, sinuses FTL
I really wish there was a way an external microphone could be used while recording video.

My problem is with the recorded audio. Has anyone found an app that let's you control audio gain. Serious clipping for live music records.

Its the quality (bitrate) in which the audio is recorded. At stock, its set at 64kbps and a sample rate of 44kHZ which is pretty subpar.
There's a hacked camera apk that lets you record audio at 194kbps with sample rate of 48kHz and also raises the video bitrate by a tad as well.
A tremendous difference in quality.

The graininess is caused by poor lighting. I went to sea world with my girl this week and all the outside video's came out amazing. But, inside shots with low light all came out very grainy. I can't blame the sensor too much because like someone mention before the same happens on high end camera's. But, also remember professional shots are taking with very high end lighting equipment.

Increase the frame rate to 30fps

Ive noticed that the Galaxy Nexus can only record video at a choppy 24fps. I was wondering if there is a way to increase it to 30fps. This phones has more than enough power to do so and I'm not quite understanding why it is so low.

from what I had read of the specs on GSMArena, the camera is supposed to be capable of 30fps.
of course, GSMArena have been wrong before...

Film runs at 24fps. Bluray also runs at 24fps to match the film so that you don't get any nasty 3:2 pull down or audio speed up due to frame rate conversion.
That's no reason why the Nexus should default to 24fps, but it does explain why the frame rate is present.
Just out of interest - when you go to the movie theatre do you complain that it's "choppy" because of the 24fps shutter?

People upgraded the Droid 3's video fps from 20 to 30 so it shouldn't be too hard to do for the Nexus.
im sure we'll see something when the dev community kicks in as the phone is released

It's because film is recorded on proper 'film' which allows soft blurrs to occur. On a digital camera that has been converted into video duty, low frame rates makes things look like claymation (simply because the camera is taking 'photos').

Makes no difference. Those "photos" still contain motion blur. What do you think the individual frames of film are?
Also many modern "films" are shot digitally at 24fps.

Even though 24fps is good enough for film, wanting to record at 30fps is not an unreasonable request. 30fps, or more specifically 29.976 fps is a VERY common framerate, in fact this has been the color NTSC video standard since 1953.
It definitely should be supported, as it gives recordings a certain "feel" just like the 24fps rate gives a certain "feel".
My guess is that someone will figure it out if they haven't already for this device like they have on other devices.

Oh, I agree, as I said in my post I was explaining why that "odd" frame rate was present, not arguing against 30fps being available.
I would expect to find 24, 25, and 30fps options. Not having my Nexus yet I wouldn't know.
It would also be nice if it supported 60fps at 720, but I haven't seen anything to confirm this.

I thought the specs listed 30fps @ 720p, 24fps @ 1080p. Not sure where I saw that, have to go look.

Movies are filmed with $100,000 cameras. They are always following a subject and use a lot of motion blur. With all of this, you cant see choppiness. You shouldn't give Samsung/Google excuses for poor performance. This is a $650 device coming out at the end of 2011, I expect top quality. Luckily this is a Nexus device so im assuming work could be done to fix this.

Ahhh, understood... 60fps @ 720 would be pretty sweet as well.

All video settings (480P, 720P and 1080P) are set to 25fps and are not changeable from within the settings menu.
Im sure that it can be hacked to give more options but for now thats all you get out of the box.
1080P does look outstanding though with no choppyness at all.

Have you seen the Galaxy S2 and iPhone 4S videos? Now thats outstanding and smooth. I dont know why Samsung chose not to put the GS2 sensor in the Galaxy Nexus.

That can hopefully be changed in media_profiles.xml later.

So the OP is talking rubbish then when saying only 24fps setting is available?
I did suspect that. I wouldn't have expected 24fps to have been available at all, so for me I would have considered it a bonus feature not something to be complained about.
It's interesting that there is not a 576p option, given that 480p at 25fps doesn't make any sense since it doesn't match any standard - I'm not sure any TVs would even support that. It should be 480p30 or 576p25.

Is it easy to access the media_profiles.xml? Im surprised no one has created any quality enhancements for video like what was done for the Galaxy S2. This camera is crap

anyone gotten anywhere w/ this yet?

Who cares? The GNex is awesome and if ANYTHING is possible on it, then the dev community will crack it and find it

Is [email protected] due to the software?

As Google announced at their event, the GN should film [email protected], but after seeing the many review which are available on the net, the conclusion is that the GN only films at 24fps.
Could this be fixed through software? It would be a huge lie, if Google mentioned 30fps, reality being something else.

i would also like to know that.. really dont like 24 fps

Is that why the videos seem so choppy ?

generally, most film is done at 24FPS which is the standard for NTSC. in the past, they would 'convert' films to 30FPS by "splitting" the A/B fields in the video in an attempt to give it a more fluid sort of feel. they originally did this for older tv sets though...
if you were watching such films on a newer TV for instance you could tell a video's been converted by seeing occasional weird doubling/lines appear in motion-filled areas. tv's/pc's though have software "filters" to hide this effect, at least the lines part.. but if you have good eyes you'll still see the occasional doubling(ghosting).
considering the compact size of the GN screen though, you should not see "jerkiness(choppiness)" unless it's some sort of hardware or software related issue.
[EDIT] although it would still be weird to do a full 1080P video and limit it to 24FPS even if you are just watching it on your phone. the whole 24FPS thing was from the DVD days.

This is normal spec of 1080p videos. If you had an HTPC you'd probably already be aware of this, as some videocard manufactures have a bug were it's not fully 24fps, or alternates causing you to see a shudder..

When filming at 1080p it is usually done at 30fps...

The FPS is usually capped in media_profiles.xml that you can find in the source on AOSP. That's where the quality settings and codecs used per setting is defined.
