you'll get a list of all available/tweakavle properties on the last
outlet right after selecting the codec.
these properties are the ones reported by the backend (libquicktime in
this case). Gem cannot do much if the backend reports properties as
being available but then refuses to use them ... :-(

in this case, Gem doesn't set anything. it seems that libquicktime has
problems communicating with one if *its* backends.
