[Q] Low frame rate of galaxy 2 front camera - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I try to access the front camera of this phone.
From the debug information, I get that "preview-frame-rates" of the front camera is only 15.
Therefore, when I record a video with this front camera, the maximum fps I can achieve is 15.
However, when I use the default Camera app from the phone and try to record a video from the front camera, I can get around 25 fps. Not sure how this app can do this. Any comments are welcome.
Another interesting thing is: by using the Camera app from the phone, there are two modes with front camera, one for video saving and one for image saving.
It is very obvious that the live preview in video saving mode is much faster (around 25fps) than the live preview in image saving mode (around 15fps judged by eyes), but it is also darker. I guess they use different settings for exposure control for these two.
Is there anyway we can get achieve a higher preview-frame-rate of the front camera ideally through android sdk???
Any insights are welcome.
Thanks.
George

Good question, the low camera framerate in darker conditions annoys me too.

Fast sound triggered camera?

Hi! I'm looking for a camera app that can be triggered via audio, but also take pictures at a SUPER fast rate.
I've found Sensor Camera. This, as the name suggests, allows for capture of photos through a variety of different sensor methods. Light, Sound, Motion, etc. It has great control over the audio input levels but takes way too long to process each photo between shots.
I've also found Fast Burst Camera. This is perfect!! From what I can tell it uses the video camera in order to get the frame rate up to 30fps. Setting this to single shot, with no image review, allows for amazing speed & control over capture.
Wondering if anyone knows of an app that combines the two? Or if not, would it be easy to make? Had my first go with the Android SDK today, there's definitely a LOT to learn.
Questions should be asked in Q&A forums, not Development forums.

[Q] Camera

Hey everyone. I was just wondering what was everyone's take on the settings for the camera. I'm still undecided on the Anti-Shake usage in camera mode. It seems that it has a tendency to add more grain/noise to the picture (you can even notice it by carefully looking on the screen when you enable and disable it). Does it really help reduce blurry photos (since the phone does have digital image stabilization)? Also, same thing for video mode using video stabilization. Is it really beneficial to have it enabled? Since if you take pictures while recording, I think the resolution of the photo alters. Just wanted to know what would be the best settings in overall day-to-day usage.
I was just coming in here to complain about the camera myself and see what others are saying for best settings. I cannot either seem to get mine to take pictures without being blurry - in any type of light or with the flash.

What is best video options for different recording types

I want to ask something about some different video recording situations
What is best video recording options for wide angle video output (quality, stabilisation fps etc...)
What is best video recording options for normal angle video output (quality, stabilisation fps etc...)
What is best video recording options for X3 zoom video output (quality, stabilisation fps etc...)
I see not so many video options but you know what I mean, it's resolution.
Resolution changes the field of view output of video.
What are your settings and why are you using that for different situations.
Shine my dark road with your light of wisdom
I use :
- 1080p 30fps : when I film in a regular way such as filming landscapes, or filming things I don't intend to put an emphasis on
- 1080 60fps : I use this more when I have "living" subject on my frame, such as filming my friends laughing or doing whatever they are up to. The idea is to be able to apply a little slow motion in post to emphasize some moments.
- 120fps : that option is on the slo-mo options. I only use that feature in great lighting and if I intend to create a more dramatic look to the moving subject I wish to apply a slow mo on. But I rarely use that feature since I don't have much opportunity to capture fast moving subject.
I recommend using the Pro mode for video since you can control the focus. (Manual focus, autofocus, focus lock)
Your camera settings depends on what you want to shoot. You will have to play around with all of them and well switch from a mode to another depending on the situation.
30fps provide better image quality
60fps is smoother but somehow less sharp in some situation
120fps don't use it if you don't have enough light otherwise you'll end up with a blurry not sharp not good looking slo-mo.
There are 3rd app such as FilmicPro that gives you more freedom with the camera settings. But I don't use them since I haven't found one that take advantage of the 3 lenses that comes with the Mate 20 Pro. So now I deal with the stock camera in Pro mode.
Hope it helps
This helps a lot. Thanks for posting details.

Camera App Fixes?

I've watched a couple of reviews and read others regarding the camera apps and performance, such as the erratic HDR performance and slow switching between cameras, RAW support not available in all cameras, frame rates in video, and so on.
Notably this one: https://www.youtube.com/watch?v=fjSX1j4WBRo and this one: https://www.youtube.com/watch?v=TrZAb4dUfHQ
Has Sony since then launched updates to fix these issues?
Avoid this phone if you;re planning using camera. None of it has been fixed...

the launch speed of the camera is normal like the other high-end, there is just the ultra-wide angle or there is a delay but on most other smartphones this delay also exists. For the range I did not notice anything strange, it is normal and not exaggerated (the dynamic range is different from the HDR which is purely software to access it must pass a manual mode), for the rest it acts as their camera (for example in landscape there will be the backlight settings but if there is a human in front of the forces will highlight the face ...). For example, there will be a photo in auto on the stock camera and Google cam HDR +, I much prefer the rendering, the details, the noise of the camera stock.
Camera works fine, dont believe everything you see on the internet. I have this phone since september and camera app has not crashed once since then. So, yeah..
I hope they will finally fix lack of 21:9 mode in main camera, lack of 4k 60fps and 4k video stabilisation crap that actually is disaster...
None of those were fixed :/

21:9 photo mode is pointless when you can take a 4:3 photo and zoom in to 21:9.
That's all the 21:9 mode would do so not much point investing it in
