Creator shares AI animation workflow: defining per-character voice traits is the key to consistency

A Reddit creator shares hard-won lessons from making AI-animated short videos since MMH3, using a consistent SA + LoRA workflow.
- Voice sync was the hardest part: after 2-3 days of experimentation, the fix was assigning each character explicit voice traits (tone, pacing, personality) and stating in the prompt who is speaking and who should lip-sync.
- Keep prompts short: style, character, camera shot, dialogue, and voice characteristics are usually enough; overly long prompts break results.
- A full voice-prompt example is included, covering voice descriptions and how lines should follow sound effects (e.g., a sneeze into a surprised line).
- Accelerated LoRA beats quality sampling: CK at 25 steps caused frequent speaker mismatches; the 8-step accelerated LoRA stayed consistent and faster.
- For visuals: use a local LLM to break the 10-second scene into shots based on style, characters, and voice traits before generating images — better than starting from a single appealing storyboard frame.
The author tested many setups and ultimately returned to this same workflow.
