# MiniMax H3 Contex Loop 3070 Safe 60s AWQ INT8

## Summary

Best-current `MiniMax H3` imported-video extension master for the maintained
optimized lane. It takes the proven MiniMax `ref2v` stack back into the
`Contex Loop` family so an existing clip can be extended through a server-safe
continuation workflow.

This variant keeps the `Contex Loop` existing-video flow, swaps to the proven
`INT8` base model, drops the Heretic text encoder, disables the failing
`MiniMaxH3MemoryEfficientSageAttentionPatch`, and expands the continuation plan
to `6 x 10s` clips with review pauses disabled.

## Status

- `best-current-extension-master`
- `server-safe-loop-60s-test`

## Workflow asset

- `workflow.json`

## Built from

- successful ComfyUI run `cc74efa5-1a53-4b2a-9d7c-7170ea7eba5b`
- the maintained `MiniMax` `ref2v` stack used in `optimized/image-to-video/minimax-h3-best-current-r2v-master-480p-3x10s/`
- earlier compact `Contex Loop` experiments that established the local-safe continuation budget

## Key model stack

- `minimax_h3_ref2va_pruned_int8_convrot.safetensors`
- `qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors`
- `minimax_h3_video_vae_int8_convrot.safetensors`
- `minimax_h3_audio_vae_fp32.safetensors`
- `minimax\minimax_h3_ref2v_lightx2v_turbo_4step_v0.1_resized_avg_rank_20_bf16.safetensors`

## Main changes

- switches from the `w4a8` loop stack to the successful `int8` `ref2v` base
- replaces the Heretic encoder with `qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors`
- keeps `SolAttn`, but bypasses `MiniMaxH3MemoryEfficientSageAttentionPatch`
  because it crashes on the current server
- sets `prepend_original=false` so the assembled output is a generated `60s`
  continuation rather than source-plus-extension
- disables the review gate for unattended queue runs
- expands the plan to `6 x 10s` continuation shots with continuity-first handoff

## Why this is the kept extension master

- Chris's current extension path should live in the `MiniMaxH3Chain*` /
  `Contex Loop` family, not as a pile of separate optimized siblings
- it is the cleanest current bridge between the proven `MiniMax` `ref2v` stack
  and imported-video continuation
- it avoids the current live-server SageAttention failure path while preserving
  the stronger `INT8` model route

## Notes

- Queue with a real server-side source video override because the placeholder
  `1.mp4` is not present on the live ComfyUI box.
- This is intended as the first unattended minute-long loop test, not the final
  quality-maxed master.
