The problems with small analog video tape formats are these: The color signal is recorded very low resolution (heterodine color), the signal to noise ratio of the recording is barely acceptable for the original first generation recording, the time base of the recording is unstable, and barely acceptable on first recordings, and the errors are exaggerated on dubs (severe flagging at top of screen). Just try viewing a second or third generation VHS dub on a TV made before home video became possible. Later TV sets were designed to somewhat compensate for the time-base issues. Oh, and the average unit, VHS, Beta, U-Matic only resolves about 220-240 lines of resolution, which was barely good enough, considering the potential video could have 440 lines of resolution.
