Thanks, yes the colour keyframes I find confusing, it’s not clear to me how to operate them, I tried to set a colour keyframe at start of clip – inverted vignette of people walking- set gamma point of
the outside of people walking, then go to end of clip set keyframe of same gamma point, so gamma setting is the same over time. But as I explained the vignette inverts at a point throughout clip. I’ll post a pic of keyframe window.
Thanks again
