Super VHS is a high-band technology capable of more than 400 lines of horizontal resolution. That's 160% resolution compared to ordinary video - great for large screen viewing and master tapes. For really important recordings you plan to keep indefinitely, use S-VHS cassettes to assure the highest possible quality. Or enjoy high resolution more conveniently, because the Super VHS ET function lets you record Super VHS images on standard Compact VHS cassettes.The 3" (GR-SXM770A/SXM470A) or 2.5" (GR-FXM270A) high-resolution viewscreen rotates 270?? so you can tilt it down for high-angle shots, or point it forward for self-portraits.
