[Q] Random fps settings when recording (HD) video - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I´m running a standard S2 with latest LP7 ICS Stock-Firmware.
recently I discovered a very odd thing about the S2´s video recording. While the general abillities are quite good, it seems the device is recording every video with a random fps rate ... especially when recording 720p or 1080p ... i recorded 4 sniplets in a row and EVERY one slightly differs in frame rate ... 29.384 fps, 29,031 fps, 29,782 pfs ... this sucks the big hairy meatball folks! How am i supposed to cut and edit those to one clip without re-rendering all to one steady frame rate?
Also tried LG Camera pro but same problem, despite fixing the frame rate to exactly 30 fps. Anyone hading the same problem? or even better - having a solution to fix this?
Thanks!
K.

Use a good transcoding software.

Anyone?

[THINK TANK] 720p encoding on nexus. DONE NEXUS ONE FTW

GOT 720p clearing up the hack a bit and will release it most probably tomorrow
sorry for the confusin
http://www.megaupload.com/?d=RP7LCIU4
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:

Haven't tried low light, but that is using MoDaCo A21 Desire ROM.

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.

[Q] Camera FPS

I know the camera records 1080p at 30fps, but I was wondering if it records 720p at a higher frame rate such as 60fps? I have been searching but can't find an answer anywhere so hopefully someone with the phone can enlighten me!
Already set on getting this awesome phone next week, but recording at 60fps will be the icing on the cake, cheers!
actually if any phone today can do its the sgs2.. now all we need is some modding..

[Q] high FPS hack?

Hi,
I was wondering if it would be possible to record video at a higher frame rate than the current 30?
i know it will be barely possible at 1080p because of the enormous amount of data to be handled.
But what about 720p or 480p?
Is there a possibility that the camera sensor can capture more than 30FPS at a lower quality/resolution?
Wondering if someone already manage to hack the camera for high FPS recording, since Siyah kernel has lift the FPS limit from 30 to 120.

Is it possible to increase fps in sgs2 video camera at lower resolution?

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.
If you cant record in stable 30fps in the Galaxy S2 look at this thread:

Meh, many problems with this phone regarding camera, its such a shame it has so much freaking potential... and yet they decided to let it rot with its issues.
I guess ive learned my lesson with samsung, probably will go for Sony next time but i hate the fact that i wont get OLED screen.
Thank you for your reply and for showing me that thread
Have you Tried lg camera app? It has the option to record with more fps @ lower resolution. You can give it a try

I have tried lgcamera and it doesnt work.

Video quality

Your friends are never going to believe what you did. The only way to prove it to them is with that video you took. Rate this thread to express how videos shot on the Huawei Mate 9 come out. A higher rating indicates that videos are smooth (and not choppy) and that auto-focus works very well, and that the camera adjusts quickly to different lighting conditions while recording.
Then, drop a comment if you have anything to add!
Anyone else notice a jitter in video recordings? I have several recordings where I see jitter.

what firmware are you on?
it is jittery. not like iPhone
Haven't noticed any jitter recording 4k videos. In fact they are much better than my Samsung S7 edge ones. Thanks to h265 codec used and much more portable and storable.
A video of my dog by night. Original video is at [email protected], but it seems the preview doesn't support it:
https://goo.gl/photos/6fgmiYijYDDVs7Yb6
yes, my phone jitters when playing recorded videos. it looks like its very sensitive to movement or no stabilization?
***jitter is gone after recent firmware update tho***
I have jitter in 4K video recorded with my mate 9 , too
Huawei can fix this problem with next update ?
I think its software problem.
