Is there a way or tweak to get the camera to record at VGA or WVGA @ 30fps? I have a 14 month old daughter and im constantly taking pics of her for the familly ect and noticed that when recording video the framerate is very laggy or slow motion like. The iphone 3gs records great video quality and the N1 has better specs so id assume higher frame rate on record is possible with the N1 also.
Any thoughts anyone?
Thx Guys!

People trip me out some time with there smart remarks.
If you like carrying around multi devices good for you. I have a stand alone camera that does video record ect but my camera is not ALLWAYS on me.
The same way the Nexus is good for multi media such as mp3 / and watching videos but I dont go buy a PSP or ipod touch for that I use my phone. The point of the high end phones these days is to try to limit carrying multi devices on you at all time.
With all the hacking / ports / tweaks going on just wanted to know if 30fps video record was possible. If you dont know how or dont know what im talking about please do reply with BS. Thanks.

i don't think he was in a bs kinda tone. hard to tell on forums
you'll thank yourself later for using a higher quality camera (dedicated camera) of any kind for videos one day. proud parent here, know whatcha mean about wanting to capture the cool 'new' moments.
now then, as far as recording, i'll bet there are settings you can change for it someday. right now the video quality is pretty darn good. just dumped a couple of videos from mine today. frame rate is quite good, picture clarity good, fps decent.
IF YOU FIND an app or way to up the settings, PLEASE update this thread in your original post.
Yeah, Im not trying to come off negative to anyone. I have a decent standalone camera that can take great pics and video a 10mpiexel cam with ful vga record. With phones tho its so MUCH MUCH MUCH more conveient to beable to snap a picture and have that picture allready able to send as MMS / Email / Up Load to facebook ect...
With the standalone camera I have to take mem card out - load to card reader - copy pics to mem card on my nexus - ect...
Just too many steps. When I had an iphone 3gs for a lmited time I was amazed at the video recording quality from a cell phone.
Now with the nexus with specs better then iphone I dont see why we cant get full 30fps at WVGA or VGA res. With 1ghz CPU and 5mpxl that should be possible right out the box. Seems like its definetly possible and im all for the ability to carry less devices.
it would be great if we could get 30 fps on the nexus. my under powered n97 does 30 fps and its video quality is a step up from my nexus for sure. kinda disappoints me that the video quality isn't just as good as my previous phones.
the moto droid (with lower specs) can do 30fps with some hacking... im sure its some setting in the rom that we can change
http://www.droidforums.net/forum/droid-hacks/19647-increase-camera-video-quality.html
HTC Desire with similar hardware does 30fps.
I don't know if it's HW or SW limitation, though. Did anyone try to record video on Desire ROM and can verify the actual fps?
Well, the Desire ROM allows for WGVA recording. I do not know about all the fps stuff, but I do know that I am recording in WGVA.
You should be able to by modifying the camera driver in the kernel and the build.prop. I'll look into this when I have the time, but I found the line that should control frame rate. A commit says that not all cameras are stable at 30fps, but how's that ever stopped us?
Hi guys, I'm thinking about buying the Samsung Vibrant (That's the US Tmobile version of the Galaxy S for clarification) and I noticed that it can play 720P and it has a WVGA screen. These days, a lot of phones are capable of technically "playing" 720P video but none, even including the almighty retina display, have hd capable screens. But I was just wondering, besides being able to play its own recordings, what is the point of watching HD videos on a screen that really can only play 450P (keeping to true wide screen aspect ratio of course)? It just uses more battery and system resources to decode the higher res video when the end result is identical. Watching 720P on a WVGA screen is tantamount to hooking up a Bluray player to a non-HD screen. What's the point?
And yes, I'm well aware of the phone's DLNA capabilities.
Beats re-encoding right?
I think because the screen is so small and the resolution is high, it gives you the illusion of watching something in HD. If you compare a DVD rip to a 720p video on Galaxy, you'll definitely notice a difference. And the Super AMOLED screen helps too
Yeah, I can see how it's more convenient to just throw it on there raw but it seems like I'd rather take the effort to make it a lower resolution to save space on the phone if it looks the same either way?
And is there really that noticeable of a difference? I'd love it if someone could show a comparison picture between the same scene of a video in 720p and 480p on the galaxy screen to see if it's significant. Also, it might be possible that android is using sub-pixel interpolation to emulate the higher resolution.
Well the screen is a tiny bit wider than the 720 pixels you get from a DVD. Better to downsize than upsize, especially on such a sharp screen! I find that when watching DVD quality videos on a laptop, you notice the artefacts and low quality less than on the phone.

720p is actually 1280x720 pixels, the phone has 800x480, there should be no difference to your eyes from viewing a high quality 480p video or a 720p.... People are probably comparing a low quality 480p DVDrip with a high quality 720p video, and that's why they are seeing a difference (color quality and sharpness play a big roll here). It makes no sense to watch HD content on the phone, a good 480p will look just as good and will take less processing power...
Thank you!

That is exactly what I've been saying this entire time! And since true 480p is actually 848 x 480, I've been encoding all my videos to 800 x 450 because my hd2's screen just can't take proper advantage of hd. Somewhat ironic considering its name. It requires less processing power and with good encoding, you lose very little quality compared to the original video. This whole 720P playback seems to be just another marketing ploy like the megapixel battle was. Just another bullet to throw on the spec sheet.
Update: If anyone reading this would like to test the quality difference between video resolutions on their respective HD capable device, here's a great test clip in several resolutions: http://www.bigbuckbunny.org/index.php/download/
Yes, it's ideal to reencode to maximize size usage if you're gonna keep the video on the memory for a period of time.
However, for those HD videos that you've downloaded, and you have no wish to dl a SD version of it just for portable viewing, and it's something that you're gonna watch once and delete, that's where the functionality to view HD media comes in handy.
In short, it's more convenient to have the ability than to do without it.

Hmmm good point. I suppose I'll just chalk it up to "convenient but not very practical." Thanks for all the great replies!
Very true and i believe the 720p which actually is for the video output..i just got the Nokia CA75-U cable and the 720p video playback is amazing on big screen TV.

That's not 720p, it's standard definition tv.

Yes, but I meant DVD resolution which has 720 pixels in width.
Besides, my entire collection is in 720p HD.. So when I'm going out and want a movie/series with me for boring times when travelling, it's nice to not have to convert them/re-download a lesser quality rip.
I also think I see a difference, tested with a SD-rip of Top Gear vs HD-rip of it. But might just be in my mind Seems sharper though.
You kow, videos encodings are at different resolutions for luminance and chrominance data.
Color data is often half or quarter the resolution of the actual video resolution.
A properly encoded 1280x720 video will look better than the same encoded at 840x480.
Considering the processing power, when video decoding and scaling are done by hardware, power consumption will be almost identical.

Not practical only for you maybe, but different people have different needs. Don't assume that you can decide for the whole world.
I was wondering if we could get 640x360 at 120fps video recording without audio on the phone as 1280x720 at 30fps is already there.
So if the phone can process 720p at 30fps then it should also do 640x360 at 120fps or even 320x180 at 240fps(for ultra-slow motion).
If this is possible then we can reduce the video playback framerate to 30fps(on computer or on the phone itself if it is possible) and the video would be in slow motion.
I read that by editing the media_profiles.xml we can tinker with video recording settings, i think it is available on froyo only.
So can the leaked builds for SGS can they be used?
I would be getting the SGS on my birthday so can't try it myself.
Till then i am gathering information on mods that can be done to enhance the android experience.
Thanks in advance.

I would love this. My girlfriend can do it with her Samsung Wave, too. I'm so jealous
I found the topic in another sub-forum before, but there doesn't seem to be much interest in this.
http://forum.xda-developers.com/showthread.php?t=726111
Bump
Would love this feature too
Im not sure if you can just decrease the pixel and so increase your frames per sec
I think this depends on the camera....
Because if you think backwards... you have 640p at 30fps, and you would turn it in 15fps, the resolution increases ? No, i think the Wave camera simply has this feature to film 120fps....
But please tell me im wrong, because i would also love it !!
I think its true that the camera must support this feature. But it's also about the throughput of data which has a certain maximum. That's why the resolution is reduced a factor 2, and enabling a frame rate of 120 fps, without exceeding the maximum data throughput.
But I also think that if it's possible on a Wave, it must be possible on a Galaxy S. I'm rather convinced they use the same camera, judging from the samples recordings made with both phones.
So hopefully, somebody can jump into this. Or give a real explanation how this slo-mo recodind works.
(Is it really a high shutter speed, and do you need a very highly illuminated object, or do they make use of some interpolation technique?)
Can anybody try!!!!
Can anybody running leaked froyo on SGS try this by editing the media_profiles.xml
i guess it might work as cyanogen mod 6 enabled 720p on the nexus one.
By editing the media_profiles.xml we might get 120fps video which can be slowed on computer(by reducing the video playback to 30fps).
Technically speaking i think it is possible if the camera is not causing a bottleneck, because the data rate at which 720p is encoded is enough for 640x360 at 120fps if we do the math.
So please it is my ernst request to all the pro-mods to try this.
Any news on this matter??
it occured to me that we could extract the cammera app from a samsung wave and translate the slo-motion feature to our i9000... any hint on how to do this??
Months old topic but... BUMP!
Really not fare that WAVE can do it but i9000 cant
What a great idea - although I suspect if it could be done, it would have been already....
Fingers crossed though
Any devs looking at the possibility to record movies in fullhd, 1080p ? I seem to remember I read somewhere that it should be capable of it.
Well if it is capable of recording in full-HD then why wouldn't Samsung themselves implement it so to make more sales?

Are we talking about the same company that decided to use rfs filesystem and use reserved memory thus limiting available ram... not to mention the weak wi-fi reception / gps issues.

Exactly my point, there could be a thousand of different reasons. But maybe our devs inhere are a bit sharper than Samsung themselves...
People have made mods that claim an extra 20 - 30 megabytes of RAM. When these are applied problems are noticed with 720p recording. Imagine the ram usage for 1080p. I don't think its worth the hassle.
1080p used in mobile phones do you think will be much better?
come on!
i dont think so...
Especially since the audio is still bollixed... if they fixed that first.

Dont think it need it.
First if hardware permit to record 1080p stream the 5megapixels chip wont manage to provide 1080p frames with a decent framerate.
then if it could the optics wont be able to resolve the resolution gain.compared with n8 nokia or iphone 4 720p output you can see what there s place for improvement in this way(sharpest optic and better sensibility)
but may our dev can work on compression level to keep more fine detail , sensibility management or faster autofocus without resolution change.
think this is the only reasonable improvement we could expect by software mod
Well, I have problems with 1080p playing, let alone recording.
Anyway, the hardware is 100% capable of 1080p recording and it would be really cool if some can mod it.

Hummingbird is capable of 1080p hardware decoding/encoding. It's equipped with hardware encoders/decoders. Both of them require decent amount of RAM reserved. I think that was the issue.
5mpix sensor is perfectly capable of delivering decent framerate @720p, why wouldn't it be capable of 1080p?
Resolution is enough, there might be bandwidth limiting factors between sensor-CPU.
Optics is perfectly capable of making quite sharp photos @5mpix, why wouldn't it be capable of shooting just 1920x1080?
There will be no software mod enabling 1080p recording, without hacking into hardware codecs/drivers.
Even if the framerate would go down to 15-20 fps, I would personally really like this feature. Some moments are best captured in highest resolution possible. An idea about the memory could be to allocate needed amount on demand, thereafter releasing it again?
Thanks for confirming that our Galaxy S is indeed hardware-wise capable of recording in 1920x1080.
Actually, why 1080p? It doesn't NEED to be 1080p. Why can't we add support for 800p (800lines vertical res) or even 960p.
We keep thinking about making the jump to 1080p, but is there any reason why would couldn't ramp up the resolution higher on the camera? Just because your TV expects 720p, doesn't mean computers do when playing it back...

800p and 960p are not common, so it would make things awkward. Can't play it on a 720p screen and not properly on a 720p screen.
BTW although noticable I don't think the difference between 1080p and 720p is that big. So I don't think anyone would really notice the difference between 720p and 960p and if so probably more as a placebo than a real difference.

I agree on the odd formats. However, going from 720p to 1080p is a significant improvement, especially if you have a large ( 46" + ) flat panal to view things on.
I would be very interested in this. And for everyone saying its not needed, this is a development forum. Many many many things that are done are "not needed" but still pretty cool. He asked if it could be done, lets stick to if it can, not if it should.

720 from 5 meg camera is already seriously pushing it, almost hack wise. Normally only 8 meg cameras should support it. And im not speaking about 1080...
The sensors usually can't deliver 30 fps at 1080p even if the hardware can encode it (which ive seen no tech specs of,just various "web claims" aka moot stuff)
It's not because its a 5MP sensor etc, its about how much data can go through the sensor after it's captured (that's before the CPU/DSP!!) You have very good 5MP 1080p cameras, because the sensors can handle it. They also cost more. I highly doubt the one in the SGS can handle much more than 720p at 30fps.
i'd rather have the image processing improved than 1080p, since 1080p (if it could be done that is) will be approx the same quality as 720p, use twice the space and need twice the power to decode on other systems.
in fact even the encoder can maybe be optimized. i'm not familiar with the hummingbird, but the OMAP's have TI's own such hardware codecs and while its proprietary you can implement your own codec accelerated by the DSP.
HummingBird's codec produce "very average" 720p H264 mainline (i believe?) at 10-12mbits (!)
Compare with x264 4mbit 720p H264 high profile quality for the same source, it blasts it away quality wise and is 2/2.5x smaller in file size. besides it has a zillion options depending if you want quality, latency etc.
bottom line, if a genius would accelerate x264 via the DSP it would be awesome.
I know the x264 team worked on the OMAP DSP with little success, mostly due to rather cryptic documentation
There are plenty of PC displays which AREN'T 1080P (only cheap ones). 1080p and 720p is optimal for TV's, but not computer displays. There are plenty of computer displays which are 1200 lines vertical resolution.
And I've found a difference between 720p and 1080p, but it's more obvious on larger displays which supports higher resolutions
I'd rather have slow-motion and a proper app that enables video editing/cutting/sound mixing just with Iphone 4.

I'm inclined to agree, theres room for improvement at 720p, its like the same logic as low end cameras and camera phones alike ramping up the pixel count doesn't directly mean better quality..
Plus the phone although it should be able to currently doesn't like playing back 1080p videos...
I'm not saying everyones going to want to watch 1080p on an 800 x 400 panel, just saying you might want to play back what you've just recorded to see how its come out..
Hi all,
If all goes well, i will get my One this tuesday.
since im going on holiday short after i would like to put some movies and tv series on it to watch.
I would like to convert these movies/series to the best quality vs quantity ratio.
I could possibly leave it at full HD settings, but then the 32 GB will be full in no time.
So i can live with somewhat less quality (not to bad, i still want to enjoy the movie ).
My question is what do you guys recommend for convertion settings for video files to play back at the HTC One?
Thx!
I'd suggest using HandBrake with the iPhone 4 preset (seriously) and perhaps adjusting the resolution to match - not that 720p or 1280x720 would look any worse for wear on a 1080p panel, it'll scale up nicely and you end up with much smaller filesizes for the resulting container.
I'm sure someone will work on a new(er) preset for these newfangled 1080p screen devices but really, considering the increased size of the resulting encoded container/file (MP4 being the most preferred on smartphones but you can use MKV as well depending on your media player of choice; my recommendation is still for MX Player), there doesn't seem to be any real need to create full blown 1080p versions of material when you can encode to 720p resolution and they'll be significantly smaller while still looking fantastic on those displays.
I'd rather have 10 720p movies on a 32GB device that give me something to choose from than 1 or 2 1080p movies that take up nearly as much space, but that's just me.
