 Windows Media files (as a surround soundtrack of a Windows Media Video or
WMV-HD disc)
 MPEG-2 files with a Dolby Digital audio track
The files created are fully compatible with the normal file formats, this means
that they can also be played on computers incapable of playing surround (in
normal stereo).
The export is performed via the same menu commands (e.g. "File -> Export
movie -> Audio as wave") like the normal stereo export. You will then be asked
if the export should be in stereo or surround format.
Export Dolby Digital surround via Smart Encoding
You can also burn material to be exported with surround sound again without
the need for the Dolby Digital codec (in MAGIX Video Pro X4 or MAGIX Video
Pro X4 without Dolby Digital encoder activation) to DVD or export the
corresponding MPEG files while keeping 5.1 surround sound. To do so, use
the "Smart Rendering" option which transfers the unprocessed parts of the
output material without renewed encoding. Read more on this in the MPEG
encoder settings section "General settings (view page 387)".
The import has to be executed as a mixdown, the audio material cannot be
changed (no fades, no audio cleaning, no volume adjustment). Harder cuts,
e.g. removal of commercials are allowed, but they may not happen precisely
according to the frame, but at the GOP (group of pictures) borders.
