Stabilization model improvements

  1. The full-frame option of Stabilization would be even more attractive if it becomes possible to specify a reference frame (i.e. a user-chosen frame that is not displaced; all other frames will be displaced as required). This is interesting in case this reference frame contains information near one of its edges that should not be compromised.
  2. Stabilization consuming quite some processing time and the complete result being unknown only after the full clip has been processed, I would be interested in an option to perform the stabilization on some kind of proxy file as a fast test, prior to submitting the final run.
