I have a weak computer (Atom N270 & onboard, 2006 Intel graphics) and it's super slow to do video editing on modern resolution videos, preferably 720p and up.
I was wondering if I could manually do chroma keying without software to make it easier. Is it possible? Could I replicate what the software does manually, like, for example, painting sixty pixels into a square instead of using a fill brush in a single click? Chroma keying the entire video one frame at a time and composing a video format, or use some set algorithm to do it faster?
I believe everything made easier can be done manually in segments.
I mean it's hard to sit and wait like 2 hours to chroma key a 10 second video on these weak specs. I need to see if there's a way to ease the chroma keying process on weaker hardware.
The modern chroma keying software features are too demanding for a 1.6 GHz Atom N270.
