Might be suited best in Environment -> MLT environment?

Maybe the profiles could have a flag indicating their support.
Additionally a flag regarding bitrate support (+ some presets) and one
for 2 pass would make our profiles.xml a lot easier to maintain.
We would then for example have only one MPEG-4 profile with a spinbox
for the number of threads, a editable combobox for the bitrate and a
checkbox for 2 pass.

Of course on a larger scale there could be done much more to the
rendering dialog ...
