If you could see scan lines, you would see an even more visible moire pattern from the mismatch of the scan lines on the film and the scan lines of the telecine that converted it back to video. So, they had to carefully control the spot size so that there were no lines recorded on the film. Some kinescope (note spelling) recorders added spot wobble (high frequency up and down) to fuzz out the lines on the CRT face and make them invisible.
