Hello,
I have Samsung Galaxy S7 Edge phone.
I'm trying to record videos at 240 fps (slo-mo mode). Problem is, when configured to work at 240 fps, all my previously adjusted camera settings (such as, manual focus, iso, exposure, etc...), are cancelled andthe phone automatically being adjusted. It is very crucial to me, to be able to record at 240 fps, AND, maintain the same focus position as I've set, prior to hitting the "record" button.
Can someone help please? Maybe someone can recommend some professional video recording APP where such phenomena can be avoided?
Thanks.

Greetings...
Here is my recent observation:
If you enable the FPS and turn on the 1.3MP Camera (to take photos/videos etc), the frame rate is roughly about 14fps (on standby).
If you go further and disable the Dithering from the registry, then the frame rate can now reach to ~20fps; and its much more smoother looking around with that.
Is this good or bad? :roll:
I mean, it would have been great if this can be coupled with some other settings to find a way around the 10fps limit of the video recording (of that stupid 320x240). Changing the fps limit to 15 seems to change it within the video properties, but not sure if it is helping at the final recording yet; need to experiment some more.
Any ideas? suggestions? comments?
Thanks,
- Matt.
Going to try to explain this... When I'm using the stock Camera app, the picture is normal. But when I switch to Camcorder, it seems to be automatically zoomed in quite a bit. And when I try to zoom out, it says that since I'm recording in HD, zoom functions are not available.
This is kind of annoying because now I have to step back probably 5 feet to fill the same frame of when I was taking photos.
Is this normal for everyone else too? Or do I have some weird glitch on my unrooted and pure stock ROM?
Yep, mine does it too (stock rom). It only does that in FullHD resolution. I guess the only use middle part of the sensor to read the data to achieve greater speeds, and thus it's gonna be a hardware limitation.
Who need HD anyway ? The lens hardly catch with it. I record 720x480 and I'm very pleased with teh quality.
Change the video recording resolution in the settings pane to 1280x720 and that should fix your problem.

Yeah I noticed that.
But that doesn't make sense. In photo mode, same resolution as video mode but in video mode it's zoomed in. Like Dr. Sid said, it seems that it uses a smaller section of the image sensor to capture video. Which again doesn't make sense. Weird.
This is definetly a speed optimization - scaling down the whole resolution of camera sensor from 3264*2448 -> 1080p is much more expensive operation than just cropping the central pixels, i assume someone at samsung was VERY lazy to have done the camcorder mode in such a lame way, it's still ok for recording outside scenes but useless for in-room recording.
I find this quite annoying also. At first I was wondering if it is a ROM glitch or something, since some of the people here stated that even in stock ROM it is present also.
I hope there is some kind of patch to this, full HD recording is really awesome and I hate to see the 'zoomed' effect.
Yeah noticed the same thing just last night.. Seems to also affect the camera's ability to focus properly in video capture mode as well... Shame on them, I wish I had noticed this sooner.
Hello
I was wondering can we improve camera quality on our Redmi Pro, especialy video recording. I am very pleased with this device, except camera quality. This is not bad hardware or sensor, this is just bad software implementation and optimization. I hope that Xiaomi will improve something in future updates.
I have tried to change some settings in camera app. For best still picture quality you can set saturation and cotrast to high, and sharpness leave at medium. With this settings pictures will look more punchy and vibrant. When you put sharpnes also to high, picture look to much artificial with some artifacts.
For Video we do not have similar settings like sharpnes, saturation and contrast. It is shame that with Sony IMX258 we have such soft video recording.
I have tried to use some other camera apps, and no camera app can improve video recording quality. With Cinema FV5 you can change bittrate to 30Mbps but quality stays the same.
I noticed that in low light conditions video recording drops to 15FPS and a bitrate around 10-12Mbps with stock camera. This is awfull image quality. With google camera, recording video in low light is better, bittrate is 17Mbps and FPS is 30. Image is a little bit darker, but much much smoother than stock camera.
I have question now. What libs and settings google camera is using for video recording? It is for sure something different from stock camera.
I Have tried to edit omega.xml in system/etc/device_features. I have copied gemini.xml, edited vendor string from qcom to mediatek, set permisions like the original file. Then I renamed original to omega.xml.old and gemini.xml to omega.xml. Rebooted and camera app worked just fine. In video modes I got audio zoom feature, and in manual picture mode unlocked everything. But there is no 4K recording, regerdless that in xml file 4k was set to 'true'.
So where are the others settings stored?
I have read something about editing lib files, shared objects *.SO files. And this is very hard to edit or do somekind of reverse enginering. Maybe someone have knowlege to do this? Or we do not need to edit lib files at all?
I am ready to test everything on my phone, so if someone have idea how can we edit camera app, google camera app, or something else to enable 4k, to improve qulity of 1080p recording, or even enable 1080p 60FPS mode.
Also I have tried to edit build.prop and add line persist.camera.HAL3.enable=1 and this will do nothing. In system lib and lib64 folder I have found files with names HAL3a.V3. I dont know is this mean something.
I am just thinking that is a shame to have very capable helio x25 and a solid sony sensor and such a mediocre image quality.
Thanks everyone in advance, and I hope that we will find some good ideas for improving our Redmi Pro
You have unlocked manual camera mode including long exposure/shuttertine and manual focus? Have you tried these two features? For me just the buttons are unlocked, but no changes if you shoot a photo or used the manual zoom has no effect. Could you explain "edited vendor string from qcom to mediatek"
You are wright, I forgot to mention that those two functions do not work. I have decompiled stock camera app from system to see xml and smali files. I dont have enough knowlege to do some mods and recompile it. Maybe someone can help. So far, i have seen in those file that camera app recognize if your vendor is mtk or qcom and base on that unlock 4K video recording and other functions. We need help from someone to look at that app and try to modify it, to change some values etc.

Hey I think you get de wrong command on build.pro, the right one in "persist.camera.HAL3.enabled=1"...
And about 4k video... I don't think it's gonna work cause the processor maybe can't handle this. And 1080 at 60fps maybe it's possible.

1080 at 60 fps maybe work
So, any one knows what exactly on Android system handle all this?. It's on encoder? It's on camera driver? I don't think of just a "app" will change anything. It's has something like a encode line or a lib. Any modder? I had looking for a mod for that sensor but until now, the only thing what works is about Hal3 on build.prop.
Anyone know how to get 60 fps 1080?
Hello,
I recently purchased an AXON 7 and really enjoy using it. I was in the camera app and noticed that the slow motion quality is much worse than it should be. I went to the settings to change the quality, and the option to change the quality was greyed out and stuck at 720p. I've already tried wiping the cache and resetting app settings, and nothing has worked. If anyone could help me fix this issue it would be really appreciated!
There's nothing wrong with your phone. The Axon 7 only shoots slow motion 120 FPS and 240 FPS at 720p. In the normal shooting mode, you can set the video to 60 FPS at 1080p if you want a crisper image but with less room to slow down the footage. Otherwise, that's it.

Thank you for the speedy reply! I would change the options but i can't since the drop down menu doesn't allow me to change it. Is there any other way to fix this issue?
To change the "slow motion" options, you press the fractions on the bottom left of the slow motion screen, i.e. 1/4 or 1/8. These determine how slow the 720p footage goes.
For 1080p 60 FPS, go to the regular video recording accessed by a swipe to the right, or by pressing video, on the main camera page and then press the gear cog on the top left. Then select 1080p 60FPS. You will have to slow it down yourself in a video editor but it is an overall better image.
Hope that helps.
Installed gcam. But when trying to take slow-motion video the image become darker and the video is unstable (bad fps than normal video). Need to know if it is my problem or a general issue. Is there any fix? Also cannot change fps from 120.

Our device doesn't supports slo mo videos. So even if the camera has the option to shoot it, it won't give the satisfactory result.
