Hum, while i agree to simplify profiles, one main advantage of kdenlive is the possibility to "easily" select profiles.
Kino provides such a "à la Prévert" list of parameters, but it is hard to understand their meaning rapidly, and discouraged me to use kino (parallel to the fact that kdenlive is much more easy to use for me).

If you want to simplify a little, you could reduce the number of "default" profiles (for instance to major commercial formats like SVCD, DVD, AHCD, ...) an provide a "advanced" button where the user can specify explicitly the above parameters.
