# MiniMax H3 Contex Loop 3070 Compact Prepend 480p 3x10s

## Summary

Safer `MiniMax H3` imported-video extension master for the compact model stack
when `480p` and `10s` per generated clip are the practical VRAM ceiling.

This variant keeps the `Contex Loop` existing-video flow, preserves the
original source at the front, and generates the extension as three `10` second
scenes instead of two `15` second scenes.

## Status

- `best-current-compact-existing-video-safe-vram`

## Workflow asset

- `workflow.json`

## Built from

- `optimized/image-to-video/minimax-h3-contex-loop-3070-compact-30s/`

## 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 working canvas to `864x480`
- switched to `prepend_original=true`
- split the generated extension into `3 x 10s` scenes
- kept `5` step defaults for the compact stack
- kept `context_length=22`, `encode_mode=video`, `anchor_mode=head`
- kept source video as `1.mp4`

## Why this exists

- the smaller stack appears able to hold `480p`
- `15s` clips are more likely to OOM
- `10s` clips are a more honest ceiling for repeatable runs
