We are filming our productions at our Children's Theatre due to Covid 19. We have installed and marked a large green screen to change backgrounds in post editing. But camera panning and zooming takes forever with frame by frame keying of the green screen. I am looking at purchasing trackx and slicex from Coremelt or the Auto tracking suite from Pixel. The Pixel suite seems to give more bang for the buck.
I'm a newbie looking for suggestions or thoughts on either or other products?
Pixel suite will not have very good tech support and has issues. SliceX and TrackX use plannar tracking, so not sure how zooms will work. If you have time to wait, when macOS Big Sur is released, MotionVFX is releasing mTrack3D which may be more useful to you.
But I'd strongly advise using Coremelt over PixelFilmStudio (whom I personally do not like, to be honest).
