Hi all!
What I´m trying to achieve is to stabilize footage with vectors and
Idistort to remove some depth movement in a shot which was supposed to
be nodal pan movement.
I´ve been using Frank Reuters ITransform to "warp stabilize" certain
areas in the shot to remove some depth movement and it worked pretty
good. Good enough to be approved :)
But I´m trying to find something more automatic for future situations.
I´m testing out to generate motion vectors from F_vectorgenerator and
then inverting the values to stabilize the shot with Idistort. I´m not
so sure of the F_vectorgenerators accuarcy in this though.
I´m testing now to try and reproduce the movement of a simple colorwhell
with a sin expression with vectors and Idistort but it seem to go half
speed and half the distance. Someone who can help me out and tell me
what I might be doing wrong? Maybe this method won´t work perhaps?
Someone have other ideas?
Thanks in advance!
