Thanks for your response by the way.

All files will end up in memory which is efficient, but they are paged and
not contiguous.
For getting access to a single of those frames as pixel array in memory you
would have to read them (eg. with fopen/fseek/ftell/fread).
If you do that on a one frame after the other basis, your memory consumption
would be N+1 frames, not bad compared to the N frames memory consumption you
