How To Enable 720p HD Video Recording on Nexus 7

Requirement: Rooted Android Phone

Procedure:
Step 1: Download, install and launch a root-enabled file explorer like ES File Explorer (available on Google Play).
Step 2: Navigate to /system/etc/ to find a file named media_profiles.xml. Make a copy of it in a separate folder.
Step 3: Rename media_profiles.xml under /system/etc/ to media_profiles.xml.old.
Step 4: Cut the file from Step 2 and paste in /system/etc/. Launch it with a suitable text editor.
Step 5: Inside the file, you will find this text:
<EncoderProfile quality=”480p” fileFormat=”3gp” duration=”30″>
<Video codec=”h264″
bitRate=”4000000″
width=”640″
height=”480″
frameRate=”30″ />
<Audio codec=”aac”
bitRate=”96000″
sampleRate=”44100″
channels=”1″ />
</EncoderProfile>
Step 6: Add the following piece of code right after it:
<EncoderProfile quality=”720p” fileFormat=”3gp” duration=”30″>
<Video codec=”h264″
bitRate=”16000000″
width=”1280″
height=”720″
frameRate=”30″ />
<Audio codec=”aac”
bitRate=”128000″
sampleRate=”48000″
channels=”1″ />
</EncoderProfile>
Save this file.
Step 7: Long press media_profiles.xml that you just saved, tap on Properties and ensure that it has the following properties: User read, User write, Group read, Other read. You can see them under the Change button. Save these settings.
Step 8: Reboot your Nexus 7.
