Introduction

Spooky season just got its own film stock. On October 9, 2026, filmmaker Sam Wasserman released Wasserman's 80s Horror LoRA (v1.0.0), a free style LoRA for MiniMax H3, the open video-and-audio model. Start your prompt with the trigger 80s_horror_wk and H3 renders the scene like a worn VHS tape from 1984 or a scratchy grindhouse 16mm print from 1978. It runs locally in ComfyUI today, with one-line installers and ready-made text-to-video and image-to-video workflows.

What shipped

  • Name: Wasserman's 80s Horror LoRA v1.0.0 (80s_horror_wk.safetensors, about 149 MB)
  • Creator: Sam Wasserman (Wasserman Productions), part of his free Filmmaker Suite
  • Modality: video style LoRA for MiniMax H3, text-to-video and image-to-video, with audio
  • Open vs closed: open download. Workflows, installers, and docs are Apache 2.0; the LoRA weights follow the MiniMax H3 Community License, including its territory limits and Acceptable Use Policy
  • Where to run it today: ComfyUI with MiniMax H3 support, using the Comfy-Org H3 base files
  • Concrete fact: trained on 48 eight-second horror shots (24 VHS, 24 grindhouse 16mm), each with its own audio, so H3's dialogue and room sound keep working

Two looks, one trigger

The LoRA learned the look, not the story. The film stock, color grade, practical lighting, wardrobe, and set dressing all come from the trigger, and your prompt only has to pick a format and say what happens:

  • 80s_horror_wk, shot on VHS. gives you neon, tape wobble, and 80s home-video energy
  • 80s_horror_wk, shot on 16mm film. gives you warm 70s grindhouse grain

Wasserman's guide says you don't need to write "film grain," "VHS noise," or "retro." The trigger handles all of that, which leaves your prompt free for light, place, action, camera, and sound. Image-to-video works too: load a start frame and the LoRA nudges the wardrobe, set, and action toward the era while keeping your frame.

Install in one line

On macOS or Linux, the installer finds your ComfyUI folder, drops the LoRA into models/loras/, adds the 80s_horror_t2v and 80s_horror_i2v workflows to the Workflows sidebar, and tells you if any H3 base files are missing:

curl -fsSL https://raw.githubusercontent.com/wassermanproductions/wasserman-80s-horror-lora/main/install.sh | bash

Don't have H3 yet? Adding --with-models downloads the base files too, about 42 GB. There's a PowerShell one-liner for Windows in the repo, plus a manual route using the Comfy-Org MiniMax-H3 files (pruned INT8 ConvRot diffusion model, the NVFP4 Qwen3-VL text encoder, and the video and audio VAEs).

Settings that work

  • LoRA strength: 1.0 (0.6 for subtle, up to 1.3 for strong)
  • Resolution: 1280×704 or 1344×768
  • Length: 124 to 192 frames, so 5 to 8 seconds at 24 fps (keep it at 17n + 5)
  • Sampler: res_multistep, 20 steps, simple scheduler
  • Text encoder: the standard H3 encoder works; Wasserman notes it was trained with an uncensored encoder, so that's where darker prompts may land best

Try this prompt

The formula is trigger and format, then light and location, then who does what and the turn, then one camera move, then the sound. Here's one of the creator's own examples, the eerie dead-mall shot:

80s_horror_wk, shot on VHS. Cold fluorescent mall light, dead shopping mall after hours. A mannequin in a prom dress stands in a fountain; its head follows a passing security guard's flashlight with smooth unnatural rotation, then it steps off the pedestal, joints clacking, and walks stiffly toward camera. Tracking shot retreating from the mannequin. No spoken words.

A handy timing trick from the guide: write "at the five-second mark" before the moment everything goes wrong, so the scare lands where you want it in the clip.

Conclusion

This is the kind of drop that makes open video models feel like a real studio: one small file, one trigger word, and a whole era of practical lighting and tape texture comes along for the ride. Keep the attribution NOTICE if you fork it, read the H3 weights license before you download, and go make something that belongs on the bottom shelf of a 1986 video store. 📼
