RETRO_VHS_Screen – VHS-style Shader with Flickering REC

SHADER

A Minecraft shader that transforms your view into a glitchy VHS tape, adding flickering REC overlay, scanlines, and color distortion for horror modpacks.

RETRO_VHS_Screen is a vanilla-like shader that applies a retro VHS camcorder effect over your entire Minecraft view. It solves a specific need for horror modpacks and nostalgic builds: delivering an unsettling, lo-fi atmosphere without altering game assets or adding complex post-processing chains. Instead of relying on resource packs that change item textures, this shader directly manipulates the final image, making every scene feel like recorded footage from a degraded tape.

The shader shines when paired with alpha- and beta-era themed modpacks, where the blocky simplicity pairs perfectly with the analog glitches. You’ll see a flickering “REC” indicator in the corner, horizontal scanlines, and occasional screen shake—all reminiscent of a handheld camcorder. It’s particularly effective for horror adventures, abandoned facility explorations, and liminal backrooms-style maps where the medium itself becomes part of the threat. Because it’s a shader, the effect overlays everything including third-person view, inventories, and even the title screen, so you never leave that grainy, surveilled look.

  • A blinking "REC" text overlay in the corner that flickers randomly, simulating a live recording feed.
  • Horizontal scanlines with subtle screen shaking and tracking distortions typical of worn VHS tapes.
  • Analog color shift and chromatic aberration that bleed reds and blues, enhancing the vintage camcorder feel.
  • Some parameters adjustable via shader options — you can reduce noise intensity or disable the REC indicator.
  • Keeps the vanilla Minecraft look; no high-resolution effects or modern filters, ideal for alpha/beta-styled worlds.

Requirements: This shader requires OptiFine or the Iris Shaders mod to load. It is compatible with most modern Minecraft versions (1.16.5 and up), and works well alongside texture packs that preserve the default palette. While the effects are lightweight, you may notice a minor framerate drop on integrated graphics. The overlay is purely visual and does not affect gameplay mechanics.
