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..
So I've read that the GPU on the Nook upscales 854x400 (or whatever) to the ?x600 resolution of the Nook screen. Does this mean that:
A) The "actual" resolution is no better than any of the other 854x400 devices
B) The GPU is working most of it's ass off upscaling constantly
?
Moreover, if true, will it ever be possible to realize the true resolution that the screen supports?
Interesting...haven't heard this about the device.

All it really means is that things designed for the "normal" android screens are being scaled up by system. The actual android OS is running at its native 1024x600.
Honestly, i saw that note in the specs, and ignored it the second i actually started using the nook. Not one game or program has looked bad, and i never gave the "upscaling" a second though.

I do own and use a Nook, and I've noticed it looks great. But this line has always had me wondering:
"GPU Processor: PowerVR SGX530 Graphics Rendering: Open GLES1.1/2.0 Hardware Scaling: 854x480 scaled to 1024x600..."
This only applies to hardware accelerated video playback. It scales all resolutions up to 1024x600. It only supports accelerated playback of up to 854x480.
It does not apply to video games or apps.
i'm using modded froyo rom for about two weeks and i have one problem: why players can't use both cores for playing videos at 720p or 1080p? yeah i know that all of you would say to convert videos to 480p, but i have a big collection of hd movies and it will take weeks to convert and to go to honeycomb is death for me because of small amount of free ram and i saw some thread on htc forum to edit cpu settings to use both cores.
You could try the ICS build, it plays 720p perfectly.
Also keep in mind that given the choice, you shouldnt choose 1080i/p on the S7 anyway.
The display is WVGA800 (800x480) and it only outputs 720p though hdmi (though everywhere I read that T2 can output 1080p but neither my S7 nor S10 do that, they both output 720p)
My memory's rusty on it, but I believe 2.2/2.3 only had marginal multi-core support at best. There wernt really any dual core devices when either launched. Realistically the S7 shoulda been delayed a couple weeks and launched as a 3.0 launch device. It was literally weeks apart.
ok, ok, i know, i shouldn't choose 1080p vids but if it can play on honeycomb why not on modded froyo rom?
EDIT: How LG OPTIMUS 2X have ability to record 1080p vids on same chipset and same os(froyo)?
This should be super simple to answer, but I haven't found and answer, shouldn't csr 2 and nfs no limits run at 60fps? I feel like they did on my Galaxy s4, but I could be wrong.
Are these games locked to 30fps or is my phone not performing right?
Some games change graphics quantity depending on GPU/SoC combination. So you might get lower FPS on some games, but much better graphics, more shaders and higher texture quality and/or polygon counts.

That's kinda cool, but a bummer at the same time. I'd much prefer 60fps to max quality.
