Once more I would like to point to the thread
https://forum.doom9.org/showthread.p...12#post1895012
and the statements wonkey_monkey did on that.
Also in the thread about shekh's Lens Transform at the end
there are some thoughts about it.
As I said before I doubt this thread is the right place for
discussion the matter, as as far as I know
orig Deshaker won't be modified, and source is (and probably will never?)
be available.
However I personally think your 2 ideas could lead to a great
improvement - but only for movies with large FOV.
Good luck!
