Lost Signal VHS

🚨 Minecraft 26.2 users: update to v1.6.1. This release fixes the corrupted blue/white world framebuffer seen with Iris 1.11.2. Use the OpenGL graphics backend; Iris does not support Minecraft 26.2's experimental Vulkan backend.

Lost Signal VHS is a lightweight post-processing shader pack for Minecraft Java Edition. It keeps vanilla lighting intact while turning the final image into unstable analog found footage recorded and played back through a damaged VHS deck.

Backrooms & analog horror

Lost Signal VHS is designed for Backrooms maps, liminal spaces, horror modpacks, ARGs, machinima, and found-footage videos. Dedicated Backrooms, Poolrooms, and Liminal Night presets recreate sickly fluorescent color, humid cyan haze, unstable exposure, tracking loss, and damaged-camcorder motion while keeping the scene playable.

What's new in v1.6.1

  • Critical Minecraft 26.2 / Iris 1.11.2 framebuffer fix
  • Explicit lightweight geometry passes so Iris always supplies the real vanilla-lit scene to the VHS pipeline
  • Explicit temporal framebuffer flips for stable history across Iris versions
  • Complete v1.6 roadmap: Liminal Signal, tape generations, period camcorders, and broken-signal simulation
  • Eleven presets, including Reference VHS, Real VHS, Backrooms, Poolrooms, Liminal Night, Found Footage, Rental Tape, Camcorder 1996, and Broken Signal

Authentic signal features

  • True NTSC/PAL interlaced field weaving through a persistent history buffer
  • Smooth correlated time-base error and feathered tracking tears
  • YIQ signal processing, chroma bandwidth loss, phase errors, color killer, and chroma persistence
  • Tape generations, VHS SP/LP/SLP/VHS-C/rental formats, oxide wear, RF interference, tape chew, and frame-repeat stalls
  • 1980s tube, 1990s VHS, and early-digital camcorder responses with optional REC/battery/timecode HUD
  • Performance, Balanced, and Cinematic quality levels
  • English and Russian settings menus
