# MiniMax H3 Contex Loop 3070 Compact 30s

## Summary

Compact `MiniMax H3` imported-video extension master tuned around the smaller
working stack Chris validated today.

This variant keeps the `Contex Loop` existing-video flow, swaps in the lighter
`w4a8` transformer and compact video VAE, points the stock source to `1.mp4`,
and stretches the generated extension to `30` seconds total across two `15`
second scenes.

## Status

- `best-current-compact-existing-video-test`
- `queued-live-test`

## Workflow asset

- `workflow.json`

## Built from

- `ethanfel/ComfyUI-MiniMaxH3-Contex-Loop`
- `example_workflows/MiniMax H3 Extend Existing Video Model Workflow.json`

## Key model stack

- `minimax_h3_ref2va_pruned_w4a8_mixed.safetensors`
- `qwen3vl_32b_heretic_minimax_h3_nvfp4.safetensors`
- `minimax_h3_video_vae_int8_convrot.safetensors`
- `minimax_h3_audio_vae_fp32.safetensors`
- `minimax\\minimax_h3_fl2v_lightx2v_turbo_4step_v0.1_comfy.safetensors`

## Main changes

- set generated duration to `30s` total via two `15s` scenes
- kept `5` step defaults for the compact stack
- set source video to `1.mp4`
- disabled source prepend so the extension target stays `30s`
- kept `context_length=22`, `encode_mode=video`, `anchor_mode=head`

## Notes

- This is the saved repo version of the optimized flow.
- For unattended queue testing, the live queued run uses the compact MiniMax
  prompt graph directly so it can enter the Comfy queue immediately while other
  jobs are still running.
