Video-8, standard VHS, Betamax and U-Matic are all about 240 to 250 horizontal lines of luma resolution and around 30 lines for color in the real world depending on how good the bandpass filters are and the luma carrier. During my early days I recall 16mm was about as good as 3/4 inch tape with a good photographer while 8mm film paralleled a single tube camera recording 6-hr VHS.
