To do this properly also multiple preview windows would be 'required'
to do anything useful, Some form of A-B editing not yet present is
Cinelerra.

Maybe the first target could be:

 - create a player that gives a visual preview (in a lower resolution)
   of all video-tracks


(This could then branch off to a zillion different use cases including
linear editing)


Next target:

 - Allow audio tracks to be (hard) attached to videotracks

 - Allow interactive manipulation of the videotracks given the tracks
   are playing, or in a paused state, where visual feedback results in
   alignment. (Tackles: 3D/Multiangle/Synchronisation)

 - Allow video tracks to be (hard) attached as a group of tracks

 - Create an intermediate representation so a multi track could be
   folded
