I am getting confused with the format of the digital video. In the olden days, it was just avi and mov that I know. And the video was an SD, standard definition? Anyway, the birth of HD (high definition) seemed to have obsoleted the SD. Lately I have been reading about the 4K format which is huge one that is intended for the cinema screen. New cameras are capable of this format. How about the computer? Our desktop couldn’t even handle HD, much more the 4K.
