Default [Q] Recording at lower bitrate - editing the file "media_profiles.xml"


I have a Samsung Galaxy S4 ZOOM (SM-C105).

I use it at work to record videos (1280x720), send to the company after previous encoding to a lower bitrate. (to reduce file size) - which unfortunately takes a long time.

I would like to change the settings to immediately record a lower bitrate.
The phone is rooted and I tried to edit the file "media_profiles.xml" but it does not change anything. Even threw him out of the catalog and still camera records the old way.
Edited the file on the phone and copied another. I have a feeling that my phone does not use that file.

Did I do something wrong? Can I do it differently? Where do I change the settings to reduce the bitrate?

I tried to use other but they are not suited for this camera (optical zoom etc.)

I will be grateful for your help.
