Analog didn't have an "XxY" resolution. VHS was about 3MHz of luma resolution and 400Khz of chroma, which was 240 lines - but that was interlaced, so your actual vertical resolution was 480 lines per interlaced frame (30 per second at US rates) -- but your Y (luma) signal would change far more often than your Pb and Pr signals (which gave the color by recording how far off the Y signal Blue and Red were)
