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.

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
UPDATE!!!
links to what i am talking about. Want to change the frame buffer rate.

*What Refresh Rate Means*
With the introduction of television display technologies, such LCD, Plasma, and DLP, and also Blu-ray Disc and HD-DVD, another factor has entered into play that affects how frames of video content are displayed on a screen: Refresh Rate. Refresh rate represents how many times the actual Television screen image is completely reconstructed every second. The idea is that the more times the screen is "refreshed" every second, the smoother the image is in terms of motion rendering and flicker reduction.
In other words, the image looks better the faster the screen can refresh itself. Refresh rates of televisions and other types of video displayed are measured in "hz" (Hertz). For example: A Television with a 60hz refresh rate represents complete reconstruction of the screen image 60 times every second. As a result, this also means that each video frame (in a 30 frame per second signal) is repeated twice every 60th of a second. By looking at the math, one can easily figure out how other frames rates related to other refresh rates.
The important thing to take into consideration is how the increase in Refresh Rate improves, or doesn't improve, the perceived screen image quality for you, the consumer. Let your own eyes be your guide as you comparison shop for your next television.
Is it possible to jump our frame buffer rate up past its current 60 limitation?
I will look for some links, but i know other devices (gtab?) have jumped from 51 to 79. This will make all video and games blow our mind!

Does we have this limit ? And if we have it will not affect any thing the human eye can't see more than 60 fps and the tab screen is only 68 fps so the 60fps limitation will not affect us

I think you missunderstand what i mean.
Post updated with links to xda thread where i read about it, and a description of what i mean.

what maximum Mbit video bit rate support by xperia z1 and what framerate ? i try some app they manage 30Mbit and 60Mbit bitrate dont know what is stock camera Mbit , but video frame rate are same every where as 30fps so please any expert explain in that it will help me a lot thanks in advance
hey guys please help any one dont know about it ??
You can mod the camera and and media_profiles to increase max video bitrate to 40 Mbps, never seen anyone try any higher. Stock bitrate is 17.5 Mbps. So far, there hasn't been any luck getting video to run over 30 fps @ 1080p.

ohh u really clear my doubts mostly stating that stock bitrate is 17.5 Mbps :good: but today i try one app which record video @ 60 Mbps 1080p. is more bitreate means more clearity or only more file size ? i record 1.16 min file with 60Mbps and that file size is around 550 mb .
In theory greater bitrate should increase video quality, however, I don't even much of a difference going to ultra high bitrate, I leave mine at 25 Mbps, which seems good enough and doesn't drastically increase the file size

Ohhh ok thank for info and reply :good:
Is there a way to enable recording of 240 FPS slow-mo? I really do not mind the video being at quality of 720p, If the phone is capable of 1080p @240, I do not see a reason why it would not handle higher framerate at 720p.
where did you find info that it could handle 240 fps? i thought it was more like 60 (or 120 for 720p max)? don't get me wrong, i would like to see that, but imo this is out of A2's reach.

It records video in 1080p at 60fps or 720p at 120fps.
The 660 chipset on the Mi A2 IS capable of 240FPS @ 720P.
(https://www.qualcomm.com/products/snapdragon-660-mobile-platform)
The limiting factors here would be either A.) the camera modules or B.) software implementation.
So, in theory, yes but further testing/research would have to go into determining the possibility.
This would best be a question for Xiaomi support:
https://www.mi.com/global/support/contact/
Good luck!
and C) the willingness of Xiaomi of course
^^^ Absolutely this. LOL.
Even Mi 8 lite has 240FPS @720p, it uses the same CPU, so it is a software matter, so there should be a way to enable it.
@ond96
And you're likely right but, as of now, no one on XDA has volunteered to implement such a change.
Please contact Xiaomi and inquire further with them.
I tried to make a video in indoor light in 4K and 1080, 60 FPS, is there a reason why 4K is much less noisy? I did not think that resolution decides how much noise is there.
4K provides you with almost 4 times the resolution of 1080P thus you will most certainly see a difference in clarity.
In running a quick test, at 1080P on the default camera app, it captures the video at a bit rate of 20.0Mbits per second.
In contrast, at 4K @ 30FPS, it captures the video at 41.9Mbits per second.
So the capture size versus the bit rate is certainly going to play a deciding factor.
But there are other ways to achieve an optimal capture rate @ 1080P.
If Xiaomi gave us the ability to utilize the High Efficiency Video Coding (H.265) and dictate our own bitrate, you'd see better capture rates @1080P.
My only other suggestion would be to seek out a third-party camera application (GCAM perhaps?) and test further.

Is there an app that supports [email protected]? There is no point in recording videos [email protected] if there is 4K, but I like the idea of 60FPS.
