Dev Generates Full Star Trek Fan Episode Locally in a Day Using MiniMax H3 on a 5090

A developer spent a day creating a full Star Trek fan episode using MiniMax H3 open weights (INT8 quantization) on a single RTX 5090. All voices, sound effects, and lip syncs were natively generated by the model without needing extra audio tools like ElevenLabs.
The author shared practical lessons learned:
- Multi-shot consistency: Write multi-shot pieces in a single generation with internal cuts to avoid inconsistent character faces.
- Off-screen voices: These tend to render generically and bleed into the next speaker; keep speaking characters on screen or overdub.
- Prompting: Write expressions as anatomy rather than vibes (e.g., avoid literal 'blank face'); anchor single-word lines in full sentences to avoid TTS coin flips.
