This made me wonder if there are any plugins that would simulate the visual artifacts of head tracking, limited bandwidth, etc. for video playback, the same way as there are effect plugins for music production which approximate the characteristics of tube amps, record players and tape decks.

There is an iOS app called Glitché[0] that simulates the VHS effect for images. Video is planned. [0] http://glitche.com/ http://glitche.com/

  VHS Camcorder[0] has been making the rounds on my Instagram feed. I fear $3.99 is a bit too steep for a silly video filter. [0]: https://boingboing.net/2015/08/21/vhs-camcorder-app-makes-your-v.html https://boingboing.net/2015/08/21/vhs-camcorder-app-makes-yo...

While I haven't heard of any project that emulated the tape-specific effects of VHS, the video game emulation community has done a lot of work on emulating NTSC. For example, Blargg's NTSC libraries[1] simulate composite and s-video derived gamma curves, blur, marginal horizontal-sync, color bleeding and fringing, and more. The color "correction" really helps the look of old game systems that were designed for NTSC. I've seen GLSL post-process filters for MAME (or was it a MAME derivative?), too. Some of those even simulated stuff like the curved surface of a CRT. Also, there is xscreensaver's "xanalogtv" hack. I wonder how hard it would be to modify one of these to include bad tracking. side note: I believe MAME has (or had?) a mode that would slowly accumulate some of "brightness" from any saturated pixel that stayed the same for a large numbe4r of frames. This data was saved globally, so if you played certain old games that were very static, you would get "monitor burn" after images.

The Kung Fury short films have what appears to be a mock head tracking offset effect. Maybe they used an actual VCR, or faked it manually, though.
