There is one "VHS" effect I have not seen duplicated, and it's the SP/LP/EP switch.<br>When switching tape speeds on the same tape, there is a "peel back"  of the video, and then SP will look like a checker-board while having lower vertical resolution.<br><br>What these VHS filters need, especially when they are "real time", is a way to toggle:<br>- SVHS/VHS (400/200 line mode)<br>- Tape speed (crush vertical resolution, dark outlines on the right of bright areas )<br>- Tape wear ( creates dark outlines on the right-side of the image)<br>- Tape damage ( many of the glitches seen, are rarely seen on real VHS tapes)<br>- Model quirks. "Connected by RF modulator", "Connected by composite video", "Connected by   S-Video", "2-head", "4-head", "camcorder",(reply>), That has to be an NTSC thing. PAL never had EP (because PAL LP is already roughly the same speed as NTSC EP I think) and while there were brief tracking glitches switching speeds between recordings, the following recording looked fine.
