Degrade footage the way a well-played VHS tape degraded a picture. Effect Strength sets the look of the format, and Tape Wear sets how damaged this copy is.
The format
Effect Strength warms the color, lowers saturation and contrast, shifts red and blue sideways in opposite directions, softens the picture horizontally, and adds scanlines and a slight row wobble. At low strength the result reads as a clean tape. At full strength it reads as a second-generation copy.
Tape damage
Tape Wear fades the picture toward gray-brown, shifts blocks of rows sideways as tracking errors, adds noise and bright specks, and draws dropouts: short white streaks where the tape lost its magnetic coating. It also sets the strength of the head-switching band at the bottom of the frame.
Damage in motion
Every frame gets new tracking errors, dropouts, and specks, placed by the frame’s timestamp. They change 30 times a second and flicker like real playback instead of sitting on the picture as a texture. The same frame always gets the same damage, so the preview matches the export.
Output size
VHS resolved roughly 240 lines of detail across the picture, well below 720p. The 720p default already holds more detail than the format had, so a 1080p export adds export time without adding anything a tape would have shown.
