GOT 720p clearing up the hack a bit and will release it most probably tomorrow
sorry for the confusin

here is the image
now thats the kinda stuff im talking about !
lets get some effort on this, gonna start digging thru the source now..
it would be awesome if we can get this working !!!!!!!!!!!
Everytime there is a new post, I check this thread, sadly its just motivational comments. If this happens though, we will have one more thing that makes the Nexus and even better phone.
Btw guys, the sensor is definitely capable of it. Like mentioned by the OP, it's just the encoding that is holding this up.

What is the problem with the encoding to start with? I would much prefer to use the h264 codec to record video to start with, why does using it crash the camera app?
I think it would be better if we could get a constant bit rate for the video recorder instead, just like on the Milestone/Droid, rather than the frame skipping in indoor light conditions.
I also hope one day we can get a better audio format rather than 8kHz AMR in our video recordings :-(
But this is a good initiative anyway..

Thats exactly what I'm looking for in terms of fps. Made a thread requesting someone add the ability to records at constant 30fps and from my testing the framerate only drops when recording indoors or in low light conditions. The indoor lighting slows everything down but out side it records perfectly and smooth. If we can get that fixed by an android pro that would be great.
As for 720p I still think thats a hardware limitation somewhere in the lense or motherboard. If it was hardware possible, how come google didnt include that from the start?

Just want to second this. The audio quality is pathetic and makes it useless for recording voice. It is one thing I miss from the iPhone. I'd assume that changing the audio codec and bitrate wouldn't be too hard for a good dev (which I certainly am not).
Records VERY well in ideal outside conditions, shot this the other day:

Yes I know it works well in outdoor lighting - the point was that it skips frames indoors.
From my experience of playing DSLR
the skipping in dim environment is probably because of insufficient CPU performance. When the light is dim, slower shutter speed and higher iso is required to obtain proper exposure, thus increase the noise. More cpu resource is needed to perform noise reduction. Then if the cpu is not strong enough, it skipps
If you take photos you know when you use high ISO and noise reduction at the same time, speed and the maximum frames of continuous shooting is usually affected.
So from my view, if we cannot improve the algorithm of encoder to achieve higher efficiency(which I think is quite difficult), then force disabling the noise reduction might be a way to solve this, although the video will be noisy...
just guessing...
along with this i was also working on 30fps and 44khz sound. the max fps i could get indoor was 26, couldnt test outdoor. i am testin the sound now. Hey and 30fps is a go but 44khz sound causes fc, will check the logs. Uploading a 26.176fps video recorded on my N1. IT STILL skips some frames but the limit is lifted from 24fps stock android
Great ...
I will try it out
BUT
Your screen shot says 720 x 480 ??
That is not 720p ... http://en.wikipedia.org/wiki/720p
The 720 refers to the height, not the lines
What you have is what is commonly referred to as DVD resolution (although really only for NTSC, as PAL is higher).
Incidentally ...
The Desire camera on the Nexus One can record at 800x480, but the I think it does it at 15 FPS and crap audio. 720x480 at 25-30 FPS with half decent audio would be very cool
Yes currently only 720x480. First trying to get decent video at this resolution. Then will move to increasing resolutions.
wow
480p to 720 p is a big jump
it's 2.67X data to process...
Nexus has the capability to do that, try recording a video on ur phone and see how fast it processes a 480p video. IDC if it takes a bit more time to process and if it can decode it it should be able to encode it. 528mhz magic 32a can record 640x480 so it should be possible for nexus with a far far better processor to atleast to 720p
anybody have the exact specifications of the nexus one processor, info about GPU and stuff, the problem on 720p is the excess load on processor which makes it hang and reboot

Not sure if it helps.
I also get the FCs with H264 but not with H263.
Some phones can record slowmo at vga resolution ( usually arround 200fps )
So... SGSII with the super power, i think can do 60fps at 720p? or at WVGA?
Why i'm sayng this? ok if you go to any party, race event, or something similar, isn't the same at 30 fps than at 60fps ( more fluid )
So... its posible?
thanks and forgive my bad english
Regarding wikipedia, it should be possible...
Generally: The less the resolution, the higher the fps (found it in german Wikipedia)
But i guess you'll need an application to do that.
Well, it a bit more complicated than just less resolution means u can have more frames. You have to consider things like cmos line read spead and shutter speed. Then if some1 did an app, it would suffer heavy from rolling shutter, does now, high frame rate would make it worse. I may look at media profiles cause it would be good to see if it can

Sounds like a good idea. If someone can do this say @ 60fps, maybe we can check if there's some difference. If not much difference, then we can stick to what we have now.

My cousin have a digital HI-Performance camera, and records at 720 -30/60FPS and 1080p at 30FPS...
And i can say, there is a noticeable diference at 30 than 60 FPS, the video is more fluid, and you can apreciate more details when the camera is in movement, like in a car race.
Soon i will get my SGSII, after reconsidering to get O2X.
I for one would like this too, especially if you could go further down the scale too, something like this;
1080p30 (Default)
720p60
480p120
240p240
Naturally, filming at something ridiculous like 320x240 (yes, yes, it's not 16:9) at 240FPS may not be useful to many, it would still provide some great slow-motion shots
I also fully expect the device to be not capable of shooting at that many frames per second anyway, 120 is pushing it
Like i said previously depends on shutter speed!
The shutter speed on old cameras used to be the amount of time the shutter exposed the film to light, on new DSLR or (Single Lens Reflex) it's the amount of time the mirror locks up and exposes the sensor, for video on a cmos sensor it's the speed at which the sensor is scan-line read. So to do 120fps, it would be not possible if it takes 1/30th of a second for the sensor to be read.
After looking at this a LITTLE, I think most of the crap capability is embedded in the camera firmware. It's possible to change media profiles but they do nothing.
Could be wrong and would like to do an app that can record 60 or 120 or even more, but after looking at this, would need a better dev than I and I would GUESS even then that it isn't likely due to hardware/camera firmware.
i'm happy with my camera performance

I didn't make the comment that your referring to, but I do think your analogy is a little off. You kinda says if you had a audi and a ferrari, wouldn't you want to use the ferrari?
But it's actually more like, well we have a ferrari now lets try and tune the hell outta it (with a risk of damage) to get more out of it. Some people just wouldn't want to do that lol.
And yes, a cmos sensor creates heat, and I suspect making it read faster creates more heat. So yeah, possible damage
Personally I still want to look into this when I have some more free time though

Some phones on the market support a loot of features, but that, are disabled by default...
Like the motorola defy, have a FM transsmiter but isn't enabled...
Like the Defy, now have 720P recording, not default WVGA, that isn't dangerous for the phone...
is more dangerous to overclock the CPU, than modify system files... ( ever if u know what are you modifyng )
About 3 years ago I used to have the Samsung INNOV8 (i8510, running on symbian), first one with the wide-angle 8mpx camera ( which i suspect remained exactly the same throughout the chain of models) and there was an integrated option in the camera sw for 120fps video, low-res ofcourse ( TI OMAP 2430 with a 330Mhz CPU )
So if they, indeed, use the same camera unit does that mean it allows that frame capture rate gibberish i can barely understand?

again were not talking about an extra feature, we are talking about cranking a feature up to beyond what it is at the moment. And YES there are potential risk factors in altering read speeds of a cmos sensor, I know many cmos sensors that have burned due to normal use (manufacturing error, heat) and cranking them up increases the chance of damage.
I think you missunderstand what would need to happen, altering system files is easy, but what is actually going to happen in a hardware sense is that instead of the sensor being read 30 times every second, it would be read 120 times every second. Now, that, due to the increase in electical flow would create more heat, increaseing heat is not always a safe thing to do in electrical components.
Now I'm not saying it cant be done, or that I'm posative that it will damage my phone, I only mean to say that calling a poster ridiculous cause they don't want to take the chance, while citing a dissacosiated anology is perhaps a little wrong.
Also to say that overclocking the CPU is more dangerous is a little off unless you have info on the cmos that I cant find? As if it's rated at 30reads per second and 35 reads at 1 minute would blow it, then no, it's not safer. It's almost EXACTLY like overclocking your cpu
Neways, I'm looking to get some info on the cmos and camera info inside the sgs2 but tis hard to find.

Would be good if it was, but 3 years? Hmmm
I need to find info on the camera hardware I think
Those who are "content" are on the wrong forums
We're here to push boundaries, find new frontiers.
You're worried that using the camera at 120FPS is going to melt the device? I severely doubt that, you can overclock the I9100 from 1.2 to 1.5GHz and it gets WARM for example, but not hot enough to cause damage.
Accessing a camera at a faster rate won't generate heat, at the end of the day you're just reading the values across the CMOS sensor, it's not having to do complex mathematical calculations so it won't generate much heat, if any at all.

Reading CMOS = Electricity = heat Same with any CMOS (less so with CCD)
not sure if this post is still alive, but.
i was looking to do the same , and today i saw SiyahKernel 2.2 beta 6.
http://www.gokhanmoral.com/gm/
which removed 30fps limit.
"increased the fps limit in the camera driver (30 to 120). I hope that the one who sent me a PM about this modification can manage to use it to have better image or video quality."
so technically the hardware will not stop you now to go to 30fps+ in videos.
i tried Lgcamera/lgcamcor from market, since it allows you to select the FPS in the video recording setting (selected 60), BUT it didn't record at that FPS.
i'm guessing that the camera settings will be phone specific.
just wanted to share this , since i'll keep trying/asking around , thought the ppl on this thread might also have some experience in this
Agreed, 60fps would be great idea, as SGS2 has a powerful camcorder for making movies. PLS, anyone have any idea about that??!?!

fasburst cameras are a bit pointless imho, better to record video... cause all of these fast burst things all they do is save the on screen preview buffer....
I would really love being able to do some slow-mo videos with my SGS2, any way to do so?
The camera simply isn't built for that kind of use. You could do it, if there were software, but the framerate would be atrocious.

Probably the best and only solution. The camera was only built for up to 30fps I believe. If you know how slow motion cameras work (very high frame rate), you should see how this is a problem .
I'm bringing this thread back to life to save cluttering the board up with yet another similar one. I've been looking for an app to do the same thing and have, like other searching, not found anything to suit.
The reason I'm still chasing it down is that I had the Samsung Jet before my SGSII and even given it's age and utter lack of power compared it had the feature to be able to record video at high speed so that when played back it would be very good quality slow motion (25% speed if my memory recalls correctly).
Now, if that phone could do it so long ago with little native power and a poor camera then surely the SGSII could do something like that at the very least, even if the max video size had to be dropped to 640x480 or similar to keep the framerate more locked in?
Want that too!
Can somebody pls answer this question.. Is 30fps hardware limitation?? Really??
I once had Samsung OmniaHD with 8Mpix camera, probably not much different from any other, and 320x240 resolution it was able to capture 120fps..
How can it be a limitation of hardware? Isn't it possible to write an app that would capture even 240fps at lower resolutions?

I'm searching for this since a year from now, I think the problem remains in the drivers and not in android SO, there is one or two android phones that support is, but I dont know how exactly, if I dont misstake samsung galaxy note 2 and one motorola has slowmotion, I belive that they build a driver to use de camera as fast as possible, on other devices I think that is not possible unless some can build such driver, and that probably will need to do in some native assembler code of each device cpu and irqs, unless the company release that driver
the functions of android to get frames from camera are very limited to useless stuff and pre-set formats and fps
I dont know whats about with android 3.1+ or 4, maybe thats SO has this functionality natively
get fast fps from a ccd camera is not a MP issue nor too much CPU requeriments nor related to amount of RAM
with a windows mobile 6.1 device such samsung omnia i900, that has a 625mhz CPU and a 5MP camera you can record 120fps in 320x240, the camera of this phone has ISO 800 (it doesn't mean 800fps, but means that it can get a very tiny little power signal from sensor in a very short amount of time) but android cameras discard this features and incorporates functions very limited and related to normal users

I don't think you understand the concept of cameras well. The hardware determines whether it is 30 or 60fps and not the software.
For slow motion, the highest a consumer (or affordable) camera does is 1080p at 60fps.
There are cameras like phantom hd that do well over 1k fps but they cost 100k

Not completely accurate.
For a consumer camera, the highest framerate at 1080p might be 60fps like you say, but some low cost consumer sensors can do high fps at lower rez. My $100 Canon Elph 100HS from 2011 will do 640x480 at 120fps or (I think) 320x240 at 240fps. I've used the 480p120 option and it came out very nice for sports use, especially for reviewing batting swings with players. The sensor tech for fairly high frame rate at decent (480p) rez is not limited to >$1000 cameras, leading me to believe it's probably more software related. I don't know enough about the sensor in the GSII though.
*Edit*
Apparently the Galaxy S II uses one of two identically spec'd (according to Anandtech) sensors from either Samsung or Sony. The Sony IMX105 specs are here. According to that page the sensor should be capable of 120fps at 1/8 sub sampling. I am not entirely sure what they mean by 1/8 sub sampling, but I would assume that it means using 1/8 of the effective pixel count or about 1M pixels. If all that is true, then the hardware should be capable of 640x480 at 120fps. Some assumptions there, though.
someone knows of a camera hack for razr?
i found a little strange 8mpx photos of just 1,4MB,probably reducing compression would give us better photos (i found them already good, but better is always better) and would be good also a video mbit increase i think
no one knows about?
If you increase compression, you'll lose quality. Then why taking 8 Mpixel photos?
Just lower your resolution
I am to interested in this now that you point it out. Reducing or eliminating compression for pics and video to make them better, I can see why compression for video is needed though, i doubt the phone can write 1080P 30 at full file size with no compression.

yeah i know increasing compression, gives less quality, is what i said a way to DECREASE compression, and having better quality
yes i can lower resolution, but this doesn't always give you a visible quality increase, it's right that less pixel, gives less quality, but usually talking of native sensor resolution, if there's a possible way to improve photos, without lowering resolution, wouldn't it be better?
looking at file size, seems that:
for example i had an lg optimus 2x, wich gave 8 mpixel 3 mb (average some 2 some 4) files,razr gives me an average of 1,7 mb file size so, 2 8mpixel sensors, usually would take same quantity of details and data having a similar sensitive surface, depending on light, bigger or smaller files, but on average, file size would be similar, cause resolution, quantity of pixel (white, black colored, so changing file size) etc are similar.
on that device there was an hack wich changed jpeg compression of 15% (with more or less visible improvement depending on situation, but usually was better) and wich changed video bitrate to higher values and better fps (30 instead of 24) (also audio changed, but razr audio is just excellent as is), giving VISIBLE better results
saving an 8mpx photo with photoshop in jpeg format for example, at 100% quality, or 95% quality doesn't give you a 30/40% file size difference,
while a 15/20% quality difference, can give you that difference in file size.
i don't think that in 2012, where amazon in italy, offers 16gb class10 sds for 8 euros, a little file size increase would be a big problem
so i think, razr could better photos at stock than optimus 2x, in terms of general quality... but lower files size... for what i know, jpeg standard is the same since about 10 yeas so there are just 2 possible thinking behind this...
1) probably motorola uses some magic, give you more detail with less data
2) probably sensor is better than 2x, but can be even better with less compression.
obviously is what i can think looking at "numerical data", probably there's something i don't know about this
Hey guys, i take my phone on trips to take snapshots and videos are 2 of the list of reasons, the quality is pretty great when taking videos too but what bugs me is the 30fps limit, it doesnt semm to be 30 at all, its more like 24 or less because everytime i change the angle even slowly the image gets all shaky and blurry (nothing to do with the autofocus) that makes me think its something to do with the low fps limit but in case im not anyone knows how to avoid it?
Also when im taking lower resolution videos like 720p the fps is still 30, is there no way to change it to 60fps at lower resolution?
Thanks in advance!
At the moment its not possible to increase the framerate over 30fps.
I have a Samsung Wave capable of record at [email protected],I miss this capability in the Samsung Galaxy S2, I think it could do it at higher resolution.
