I am processing again once processed video. I have added borders not to loose the whole frame.
I use borders $FF00FF not to be processed.
I have found another behaviour.
Deshaker does not process fixed area at the border image, in certain cases. See the picture.
(1)The processing area seems to be always rectangular
(2)The rectangle is sometimes smaller than necessary
Changing
Initial search range has influence on that, but is not solution.
I don't know whether it is possible to fix (1) but maybe (2)?
Any settings?
