Camera Focus - Galaxy S II Q&A, Help & Troubleshooting

I noticed that the Camera doesnt like to focus all the time when taking pictures with the sock camera app. I used different apps and they work fine. But i want to record videos. When doing so the camera goes out of focus alot. Is there any fix or an alternative video recording app with 1080p recording?

[Q] Full hd video camera's field of view

Why when recording video at Full HD the angle of view changes ?
The higher the video resolution the narrower the field of view becomes.
Of course the lens is prime so is it using only the center of the sensor ?
thanks
zoom - wide
when recording video at 1080p the lens becomes zoom.
when recording video at low resolutions or just using the camera for photos it becomes wide lens.
have you noticed it ?
A thought I made was that because the lens is prime it crops from the center of the sensor for HD video. But what's the reason to do something like this? Easier CPU processing ?
any thoughts ?
And talking about the video ...
Is there a possibility (mod or app) to record video with the screen off ???
camera noise
I don't know about the screen but I am glad they silence the camera's shutter sound when the phone is at silent mode with the new official update.
There was someone that enabled a no-zoomed mode in the camera app. But that made you lose 720p recording, as he had to change the 720p mode into 1080p "wide" recording. Maybe someone knows what I'm talking about and has the apk for you.
good idea
Why not recording full hd video at wide and zooming in (like the camera does) when ever you want ... maybe because this means that the phone has to capture video at 8 megapixel and then downgrade it at Full HD. So this must be more CPU demanding.
Probably the phone records video at 1920x1080 using the center of the sensor. Capturing only the center of the sensor does the zoom effect. I cant think another reason why loosing the wide angle.
The narrow field of view is useful in some cases (maybe outside) but recording inside rooms everything is very close...

[Q] Camera Focus possibilities

Hi!
I've been trying to create photos and videos about objects that are close to the camera, but the phone always focuses on the background.
Are there any way to get manual focus? (Set lenses manually) - maybe from another device/rom?
I know, there is a touch to focus in photo mode, can be usefull sometimes but not perfect.
If no chance to manual focus, how can I use the Touch To Focus option while video recording? - That can't be hardware limitation, as we can use it in photo mode.
Thanks.
I use single auto focus while shooting video, works quite well for me...

Record video with both cameras, picture in picture with Galaxy S8

Hi,
is there an app, where I can record with both cameras at the same time? Full screen with the front camera and a small picture inside that full screen image with the selfie cam.
I found an app, which can do that, but both pictures have the same size, which is not that really useful.
This one: https://play.google.com/store/apps/details?id=cornopolitan.dualvideo
If this app can do full screen the front cam and small selfie cam, that would be perfect, but this setting is not available.
Or maybe there is an other app, doing this dual cam with YouTube live?
Thanks
Alex
Edit: Well, I figure out, the phone can do that almost by default.

you can compare open camera when you switch on/off EIS in 4K , i think EIS in 4K work but not too smooth. you can handle your phone to stabilitation with EIS ON in 4K to take a video. goodluck ^_^
4K in front camera with OPEN CAMERA ,its perfect you must set fps 25/30, and framerate :200 mb, EIS off, and don't shot in lowlight thats very noisy
if you have root and use camera API ,you got 4K with EIS ,it look better than before. but crash to front camera..
im sorry for my english
I've got another question. Is there a way to make gcam able to record 4k video?
gcam only focus on photos , not video .. but you can get 4k by gcam oldes apk its have default setting and you can adjust by yourself

Question: Open Camera 4K 60fps

Has anyone tried recording 4K at 60fps using Open Camera?
I'm thinking of buying this phone but there are others around the same price that support that.
I have an Xperia XA2 Ultra. Open Camera allows the main selfie camera to record video in 4K 30fps when by default
it can only record 1080p
Could anyone try the app and let me know?
I would really appreciate it
"Serious Camera Error" when 4k 60fps is set.

I just installed open camera, though I dont find the HDR option in video settings, but setting to 4k/60 with max buffer of 200 seems to record without a problem. I tried front facing camera, same goes...
I dont see an issue but again, I dont see HDR option in it, also the selfie camera on photo mode, max buffer and max quality seems only as good as normal camera app, the default camera app maybe even a little sharper but barely noticeable but if you really care for 60fps both back and front worked in [email protected] which is weird lol I never expected that, I need to go further testing to see how good the open camera is, compare 60fps in 4k to 60fps 30 and compare quality as well to get the full idea, but I did play around with photos a little bit, and to be honest open camera seemed to have much more artificial sharpness, the photo zoomed out looks sharp even sharper than default camera, but put on a big screen or zoomed in, the default camera has much more respectable sharpness that has way less noise and grain which makes the photo more realistic and more natural overall thats why I feel like the open camera is just a gimmick, all it can provide is 60fps in 4k in both cameras, but again I have to check the quality to see if its even worth it because even with quick tweaking in open camera, I still cant get the best combination of brightness sharpness and color accuracy, yet the default camera app gives a splendid true mix of those, maybe going deeper in manual settings adjusting all these aspects manually could lead to good quality outcomes, but to be honest, no one will ever want to adjust every time they wanna take a pic/video so yah
Thanks a lot Man
I get a lot of noise when recording 4K with the selfie camera, maybe because it wasn't meant to do that or it is just Open Camera.
Thanks again
