# MiniMax H3 Extension Master
|
|
|
|
## 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-r2v-master/`
|
|
- 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.
