    9 I have not used it yet but I see no options on lenience - it just says "stabilize shaky video", is the intent to freeze the view or buffer knock/sway amplitude? If the outcome is inadequate, one idea perhaps is to make the log, then edit it with the desired response (location of subject) then feed it to ffmpeg (shake!) as a cue file.

     10D) I tested it and it did something other than advertised, when I read the name "Deshake" I presumed it would only remove panning problems, but it rolled my video (at the start and it seemed to ignore the rest). The rolling might deserve its own ticket, but a roll action would mean the objective of this filter was different and a new filter would need to be written.
