I’ve been working on a shader that simulates footage captured from VHS tapes. The general plan is to have an obsessive attention to detail / authentic-looking simulation.
In order to achieve this I’ve been recording a variety of test images on a couple VCR’s, capturing clips of footage and analyzing the image behavior. That also includes the effects of tape wear and damage by folding and creasing the VHS tape, moving the tape to reproduce tracking errors and applying magnetic interference to the VCR head drum.
There are still some features to add and things to improve, but I’m hoping to get this released in the near future!
WIP
- Static glitches Gif
- Generation Loss (chroma & luma degradation from copying a copy, of a copy, of a copy…)
- RF interference (shadowing to the right of high-frequency luma, ghosting, grainier image)
- C# hooks for easily triggering certain parameters from code

Some have gifs, the color banding kills subtle details, but its better to see the effect in motion. (just images pulled from the web/tumblr, displayed on a plane in Unity)
