MiniMax H3 Character Reference Director — Consistent Characters (Patreon)

MiniMax H3 Character Reference Director

MiniMax H3 Character Reference Director — Consistent Characters, Audio References, Start/End Frames & More After several weeks of testing, rebuilding and refining my MiniMax H3 workflow, I’m finally releasing the first public version of my H3 Character Reference Director Workflow. The goal was simple: Make H3 easier to control and significantly improve character consistency across video generations. Instead of manually wiring and describing every reference again and again, the Character Reference Director manages the references, roles and prompts for you. It supports character reference images for: Face identity and different face angles Facial expressions Full body proportions Clothing Hairstyle Relative height and body scale Exact environments and locations Multi-shot character references The workflow also supports: Multiple characters Character presets / saved character projects Audio references for voice timbre Exact dialogue control Two-person dialogue Off-screen / POV speakers Video motion references Start frame Optional end frame Reference-based environments Target scene presets Community LoRAs Spectrum acceleration ComfyUI Kitchen Attention Turbo LoRA support Generated final-frame preview and saving One of the biggest improvements during development was reference prompting. H3 often treats weak image descriptions as inspiration and creates a similar character instead of the exact person. The Director now uses stronger reference-role prompts designed to tell H3 exactly what information each image should preserve. For example, body references can explicitly preserve: body proportions, height impression, chest proportions, waist, hips, glute proportions, silhouette and relative scale. The same principle is used for faces, clothing, hairstyles and environments. I have also spent a lot of time improving dialogue handling. H3 has a tendency to improvise, repeat lines or continue speaking after the written dialogue ends. The included dialogue presets are designed to reduce this behaviour and clearly separate: voice reference → speaker → exact dialogue → scene audio. Performance The supplied workflows also support ComfyUI Kitchen Attention. On my RTX 3090, switching from standard PyTorch Attention to ComfyUI Kitchen Attention reduced one 5-second test from approximately: 577 seconds → 350 seconds with no visible reduction in character quality in my tests. A 10-second generation that previously took close to 12 minutes completed in approximately 8½ minutes. Two workflows are included Reference-to-Video Workflow Best when the character references define the generated shot. Start / End Frame + Character References Workflow Combines first-frame / optional last-frame control with the Character Reference Director. This second workflow has become one of my favourite ways to work with H3 because the start frame can define the scene while the character references preserve identity separately. Who is this for? This workflow is aimed at people who already use MiniMax H3 in ComfyUI and want: better character consistency faster reference setup reusable characters more structured prompting stronger control over dialogue and audio references easier multi-character workflows less repetitive manual work This is not a magical “one-click perfect video” system. H3 still has its own limitations, and difficult scenes can still require experimentation. But compared with using H3 references manually, this has made my own workflow much faster, cleaner and more predictable.
