H3 WebUI: Motion Context plus built-in upscaling — MiniMax H3 tutorial
Chain short clips toward roughly one minute with Motion Context and upscale before export.
Audience: Users who prefer a WebUI over manually wiring a ComfyUI graph.
Hardware: Apple Silicon or the environments currently supported by the WebUI.
Prerequisites
- H3 WebUI 1.4 or newer
- A short-clip segment plan
- Enough time for generation and upscaling
Steps
- Validate a five-second 720p base generation.
- Enable Motion Context and generate in segments while checking each join.
- Apply built-in upscaling last so its artifacts do not confuse generation tuning.
Caveats
- Maximum duration and speed claims are version snapshots; recheck after updates.
