[Q] Camera slow motion - Galaxy S II Q&A, Help & Troubleshooting

There is any app or hack or mod that allow the s2 to record at higher framerate and reduced resolution?
Like 240fps and 320x240.
Or maybe 120fps @ 640x480
It would be very nice and funny
I think a dev can modify a rom to make it works.

Never heard of this
sorry
hope it helped

[Q] slow-motion camera or port of droid X's camera?

Is there a way to take slow-motion video with the Vibrant camera? I know that the droid-X has one but i cant find a port or anything that will work on the vibrant.
so if anyone knows if there is either a port of the Droid X camera or maybe a slow-motion app I would appreciate it.

The way most consumer digital cameras do slow-motion video (and video at all) is to record many different frames on the camera's CCD chip. The Vibrant's CCD, for example, can take 2560x1920 still images. It also records 1280x720 video at 30fps. To do this, it puts 4 different frames on the CCD, one after another. (1280 times 2 is 2560, so you can fit two frames across and two frames down, so that's 4 images on the CCD at once.)
To do slow-motion video, you just need to subdivide the CCD even further to fit more frames on it. This is why cameras that support slow-motion video record it in lower resolution--you're not really speeding up capture so much as stuffing more frames on a single CCD, which has limits in how quickly it can refresh.
On the Vibrant, you could theoretically do 120fps in 640x480 resolution by subdividing the CCD into a 4x4 grid (instead of the 2x2 is uses to do 720p 30fps). This gives 4 times as many frames per CCD refresh, which means 120fps. (Or you could do 720x640 at 60fps by subdividing into a 4x2 grid--half the pixels of a 1280x720 at twice the frame rate.)
Are the camera hardware drivers open source? My knowledge of Android stops at the API--I've never done any low-level device driver programming. If you can get the camera driver source, this should be possible. But I have no idea how difficult it would be.
(I'd love to see this feature, though--I found this thread searching around to see if anyone had done it already.)
Bump. I'm assuming this is a development dead end until we get the camera driver source...but it'd still be awesome to have this feature on more Android devices.
chuckbass... what you says is no sense, forgive me, but that isn't the way slow motion works, if there is a way to get a frame from an area of the ccd and subdivide in 2x2 you will get 4 incoherent images cos each will be sepparated by half resolution
Slowmotion it's dependant on how fast you can get the whole frame from the CCD, resize, apply some compresion or not, and store
in this part the RAM memory has a vital role
the proccess is:
1) get the whole frame from ccd, it's can be done by api's, but I think may be slow, but you need to test first, but through apis is more compatible
2) resize the frame, at least you can get a resized by hardware image, I think through apis the cdd can return an jpg
3) store to ram in raw mode or the jpg
repeat at fast the cpu can until fill the reserved ram
this may works to do a burst slow motion for a few second but very fast frame rate
another ways is to apply an algorithm and store in ram just if it's necesary but better to store directly into a fast SD memory to record continuously, here you can do test to find the max memory you can store to SD and maybe not using compression but just store in raw mode (like a bmp, or rle bmp)
there is no relation with resolution/frame rate and how much slowmotion you can do
I mean, if you can record [email protected] that doesn't necessary means a [email protected]
samsung omnia i900 can get arround 120 fps in 320x240 in a low bitrate video, works fine with good light, and [email protected]
Galaxy S can record [email protected], but has a better cpu and gpu
It's depends on cpu power, and/or gpu (and not in MHz)
I don't know about android programming, and just a few useless things in winmo, but I'm glad if I can help with anything
it's seems that not much ppl is interested on slowmotion, funny, cos is a very nice feature!
if there slowmotion in galaxy S or optimus 3D I will buy, but for now I will get a Casio EX-F100 and a Nintendo 3DS soon

Higher video resolution

is there possibility to get P500 to record video in higher resolution than VGA? I've tried to change values in system/build.prop, but nothing happened. I guess that the camera app is the problem, as it is made to support just 'built in' resolutions.
Anybody has any ideas? Maybe camera app from other phone? I do not look for HD of course, but little higher res & better audio than 8000hz would be nice
Which values are you using?
Try changing them in the file /data/local.prop, then restart the phone and the changes should take effect
I've tried, didn't work. I guess that resolutions are 'hardcoded' into camera app.
I remember that on Vodafone 845 I managed to record 800x480 video via Bambuser app - the std. camera did 320x240. It was crappy quality (no wonder on that phone), but with a lot of overclocking, it was usable

[Q] Reduce video recording compression?

Hey guys,
I've got an xperia mini on ICS and, although it's not my main phone I still carry it around for it's pure small-factor-size. Just seems to fit anywhere.
The only thing I'm not impressed with is the video recording. It's S**T. Camera capture is pretty decent but the video recording is so blocky and jpegy it looks like its been compressed to play on a calculator. (and yes it is set to high quality in settings)
Now I don't believe this is the best the camera module can do. Is there no kind of app that can capture raw data from the camera and not compress it quite so much?
Am I asking too much?

1080p 60fps or 45fps recording with HDR

Hi, everyone
Is there any mod for 1080p 60fps or 45fps recording with HDR? If I recording with HDR it's only 1080p 30fps and this is too slow for me.
I want this mod, because if I recording 1080p 60fps is too dark.
Sorry for my bad English
Not posible
Z2 isnt fast enough
Needs double the memory write speed for [email protected]
You can't have 60fps recording in the dark simply because there isn't enough light available. You would either have to bump up the ISO or have a larger aperture.

asking for a MOD Camera (4k and 120fps slow motion)

Hi i want ask if someone is able to make a MOD (like lg g2) to recording in 4k and slow motion video 120fps, don'tworry i look that for 5k3m2 samsung sensor it's possible and mt6795 too
our hardware can handle that sound really cool, can u give me some link?
but I think the devs need the kernel source first to make something like that

camera resolution is more 4000x3000 and MTK6795 can recording 4k videos, so no problems

I think image resolution and video resolution is completely different. MTK6795's support is not enough, the camera module need to support it too.
If not, this kind of mod will be very popular, for many device.

i asked to samsung support and they said me ''yes''
Google camera can record 4k i dont know about 120 fps
