In case of multicolor mode, i calculate an optimized charset of 256
chars that cover 4000 blocks from the original 4 frames (thus having a
bit of quality loss). In case of Petscii i make use of the C64 charset
only (that the c64 has in its ROM furthermore), and not building any
dynamic charset on my own, so i can forgo on also putting a charset into
the video itself, and therefore add additional color information.
However in that case i need all origional characters from the c64 to be
able to compare them with each block of the picture.
In case of ecmh mode i also rely on a static charset, but especially
prepared for maximum quality.
So having several ways for encoding is part of the idea.
