[MOD] Increase Camera Audio/Video/Image Quality [Updated - 18th Dec 2012]
First and Foremost, DO A NANDROID BACKUP!!!!! I am not responsible for any mistakes that you make or if anything happens to your phone.
Seeing that some users are complaining about the noise present in the video recordings, I've been able to increase the video bitrate to 20mbps.
Here's how to do it.
- Using a file browser (like root explorer/es file explorer etc) go to the /system/etc folder
- Make sure your system is mounted RW
- Search for the media_profiles.xml file and open it up in any text editor
- Once you scroll down you will see the following:
<EncoderProfile quality="1080p" fileFormat="mp4" duration="30">
- Change the bitRate from 12000000 to 20000000
- Save, make sure permissions are rw-r--r-- and then reboot.
I have tested this and it works perfectly.
I have not messed around with anymore settings yet, will be doing so next weekend. I'm kinda busy with finals week so if you all want, you can try changing other settings and report back your findings!
Note that all the details under <CamcorderProfiles cameraId="0"> are for the rear camera and the ones under <CamcorderProfiles cameraId="1"> are for the front facing camera.
Hope this can inspire more findings and more ways to make the image and video quality better!
Here are some flashable zips. I have tested them and they are working fine.
Increase 1080p video bitrate to 20mbps
I will be testing tocirahl's findings and adding flashable zips for those MODs soon.
Update 2 (18th Dec 2012)
Here is another flashable zip with the following additions:-
Both 1080p and 720p audio bitrate has been boosted to 288k (this is the max for now)
Both 1080p and 720p audio channels have been changed from 1(mono) to 2(stereo). [NOTE: I can't confirm whether this is useful as on testing, it seems like a very small increase in quality but that could be a placebo. However, I have still added it]
1080p video bitrate has been boosted to 20mbps (this is the max that is can go for now)
720p video bitrate has been boosted to 12mbps (this is the max that is can go for now)
All the above has been changed for both the regular 720p and 1080p videos and the time lapse 720p and 1080p videos.
Image Decoding Memory Cap has been doubled from 20mb to 40mb. (Image quality seems to have become slightly better)
NOTE: All these MODs will increase the file size of the videos and images.
Thanks a lot to the following users for their findings:-
If this is in the wrong section, please could one of the MODs move it? Thanks and sorry for the inconvenience!
