Playback Comparison - VHS / S-VHS / S-VHS ET probnots tech 2023-04-05 | All recordings are in SP speed, recorded and played back on a JVC-SHR7600U VCR with TBC turned on. S-VHS recording on a Sony MQST-120 tape, S-VHS ET and VHS recordings on a Fuji HQ 120 tape. Digitized using S-Video to an HDMI upscaler.A note on the vertical noise with the ET recording - this seems to be amplified with the upscaler. When directly connected to a CRT or LCD TV, it's less pronounced, but still present. This would probably improve with the use of a higher quality VHS tape, but appears to be a common complaint from what I've seen on old forum posts.Expected Horizontal (luminance) Resolution:VHS - 240 LinesSVHS - 400 Lines
