Large & CIF Camera Video resolutions hack

HKLM\Software\HTC\Camera\P2\MainCamSupportCapSize = dword:0x0A (10)
change to dword:0x3A (58) and you will have Large & CIF resolutions.
Dmitry

can u explain better how to do it because when i go in i cant change the dword value and its # is 10 for me

Use any registry editor (like Resco Registry Editor or PHM Registry editor) and going to the HKLM\Software\HTC\Camera\P2\MainCamSupportCapSize . Default value is 10 decimal (0xA hex). Change value to 58 decimal (0x3A hex).

I modified the registry for these values and it does seem to increase the quality but not the image size of the pictures or video.

After registry patch the L & CIF resolutions will be available in video camera mode. Try to click on resolution icon on top bar or select it in options.

the new resolutions are
L = 320x240
CIF = 352x288
which are much better than
S = 128x96
M = 176x144
thanks for the info

i made the edit and it enabled the two resolutions in the options, but when i actually tried to take a video with those settings (either large or CIF) it came out as the same low resolution it normally does, but the video quality is even worse (very choppy). is there a way to get around this?

No problem. HKLM\Software\HTC\Camera\Recparam\MP4Large\Bitrate
default value 128000. I chaged it to 1024000 and now video quality is better.

hey, thanks for the reply...did what you said, and picture quality is better, but video is still very choppy and still much below the framerate id get while recording in medium. id be happy if I can just get it up to 15 frames per sec at this quality.

MJPEG @ 15FPS seems to be the sweet spot with Dmitri's tweak
Thanks for this tweak Dmitry! After spending few hours testing various settings, I found that using MJPEG @ 15 FPS got me the best results in both visual quality and framerate consistency (FPS for MJPEG can be set under Recparam\AVILarge although 15FPS is the default, if I recall right). Anything higher than 15-20 FPS with high motion videos will result in erratic captures.
Note also that you'll want a fat MicroSD card to store MJPEG videos as these can become large fairly quickly.

This is an amazing reg tweak, i knew it was a matter of time before this leaked out. This camera is more powerful than whats let on and i know it
Now if only we can get some frame rate tweaks in here that work

Well I actually got the frame rate to not be so choppy by just changing HKLM\Software\HTC\Camera\Recparam\MP4Large\FrameRate to 5 Hell you may even be able to go lower. Because that's all I kept doin an it just seemed to get better each time I lowered it.

Changing the framerate to 5FPS for Mpeg4 yields horrible playback results. It's not even worth taking videos with the setting at 5 because of the slow, jerky movements.

5 frames per second? That is REALLY choppy, maybe you meant 15?

i've done some testing and it seems like mpg4 just uses too much processing power to do the compression and that motion jpeg (AVI) at 15fps yields pretty good results. will try and do some more testing and report back.

my only problem with using motion jpg is that audio stream format doesnt work with tcpmp, so all my beautiful movie automaticly become silent films out side pocket media player

help
I messup. I changed the maincamsupportcaptsize and dont remeber the org setting. the 2nd problem is that i could not add change to dword:0x3A (58) it would only let me change from 8 to 58 but not the 0X3a?

Not sure if changing this messed up my MMS but I haven't changed any other feature. Right now after doing this hack, my MMS won't send out, giving me an error that says my image size of 16k or whatever is over the 0k limit?

Reseting to default
thanks for the info but I have tried that reg hack and it will stay at 58 until i launch the camera/camcorder function then i go back in and it is back at 10. don't know if i need to soft reset before i launch cam? any help would be a appreciated.

Same thing happened to me. Just uninstall your mms and re install it. It will work.

How Can I improve picture quality ?

Hi
As I Was checking some pictures from my Jasjam, I've noticed that the quality of the pictures is nice, but the JPEG compressing it to 250Kb (In its best quality) by removing allot of details from the pictures.
is it possible to change the software to save as RAW image, without JPEG compression ?
Or maybe change the JPEG compression to 100% quality ?
Do you know any camera software that can do that ?
Tnx
Oren

Can we Reduce Photo Compression?

I've been wondering if there's an easy mod to reduce the compression used in photos taken on the Nexus One. I haven't been able to find anything using search, so I apologise if this has come up before.
It seems the files produced by the camera are too small, restricting the potential quality the camera can produce.
We can edit the profiles_media.xml file to increase camcorder resolution and bitrate, so there should be something similar for still photos, right?

hi, where is this file?
profiles_media.xml
what did you actually mod in it for vidéo?
thxx
nocomp

Found it.. I think !
Was in /system/etc and its name is media_profiles.xml
But I still can not see how to change the compression of the photo on my Xperia Arc

Changing S4 video recording bitrate

Much appreciated if anyone can tell me what I need to do to be able to change the bitrate setting in media_profiles.xml under /system/etc. I have root but it won't let me save the new value into the file.
I would like to be able to record at lower bitrate since the file size in 1080p and 720p are so huge. Looks like the max bit rate is up to 20mbit/s. default for 1080p is 17mb and 720p is 12. I want to lower to 4mb for 1080p and 2 mb for 720p and see what the quality is like.
If anyone knows of a better way plz let me know. thanks.

Changed the settings on my media_profiles.xml but it still doesn't record at different bitrate. Much appreciated if anyone can help or have been able to change their recording bitrate. Is there something else different regarding the samsung s4 cam settting?

Anyone? much appreciated. thanks

Camera mod?

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?
