Bug ID: 368961
           Summary: 16.08.1 MP4 Render Interface provides too low audio
                    encoding settings
           Product: kdenlive
           Version: 16.08.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Video Display & Export

Reducing video quality reduces file size, reducing audio quality reduces file

However, reducing audio quality in relation to reducing video quality reduces
file size in an insignificant way:
A low quality video with high quality audio is generally much smaller than a
high quality video with low quality audio.

Kdenlive mp4/x264 offers 192kbps as the maximum audio bitrate.

Premiere Pro CC exporter for h.264 format has a medium profile at 192kbps and a
high profile at 320kbps (which is the maximum possible value in the exporter).

Youtube suggests 384kbps:

Kdenlive has 5 quality settings. I suggest they get changed from

   audiobitrates="192,64" defaultaudiobitrate="160"

in kdenlive/data/profiles.xml in lines 10 (HD) and 27 (UHD) and 54 (audio only
AC3) to

   audiobitrates="384,128" defaultaudiobitrate="256"

This is assuming that audiobitrates defines max and min and that all others get
calculated automatically.

Reproducible: Always
