I am using Magix Movie Edit Pro Premium v 19.0.2.58 (UDP3). The built-in chroma key effect doesn't work very well, so I tried to use Chroma Key Pro from New Blue, wich came with the package. Much more adjustements, better results, except for one thing: it affects the new foreground video (the one to wich the effect is applicated). The images freezes for a few frames, it is not fluent at all (1920x1080, 29,97f/s). When I disable the effect, the video works fine. When the Chroma Key pro is enabled, it freezes every few frames.
Info on the PC I am using : Intel(R) Core(TM) i5-9400F CPU @ 2.90GHz 2.90 GHz; 16 Gb RAM; WINDOWS 10
Any solution ?
Thanks for all the comments, CubeAce, Gid, and John E Baker
(BTW, my graphic card is a NVIDIA GeForce GT1030). I just don't know how to answer directly to your answers...
I understand Chroma Key pro is very demanding to the system, so I'll try to cut my project in smaller sub-projects, render the files after applying only one effect (Chorma key pro) and use the new exported files in the final project.
