Con un simple mod que consiste en editar el fichero /system/etc/media_profiles.xml
Os dejo una guía y un enlace al post de XDA donde se habla de esto.
1- Open ES File Explorer and head to /system/etc/
2- Find the file media_profiles.xml and copy it (long press the file and select copy from the menu)
3- Go into any other directory and paste it there (temporarily)
4- Go back to the /system/etc/ directory again and rename the media_profiles.xml to media_profiles.xml.old and save it (long press the file and select rename from the menu
5- Now go back to the directory you copied the file to and long press it. When the menu comes up select cut and go to the /system/etc directory and hit paste up at the top
6- Now just click on the file you just pasted and a list of editors will pop up.
7- Select ES Note Editor (it comes with ES File Explorer) and locate the section in the file where it says
<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>
8- Add this code right after
<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>
9- Once added click the back button on the bottom and a menu will show up on the bottom that asks you to save click that.
10- Long press the file you just saved and select Properties at the bottom and make sure you give it the correct permissions (rw-r--r-- or chmod 644) by clicking the change button. There should be 4 check marks on that screen User read, User write, Group read, Other read. Click ok and ok again to save it.
11- Reboot and enjoy
