Simply Advanced - MiniMax H3 Workflow by altoiddealer
This workflow was built from the ground up by myself working daily over the course of 2-3 weeks, aiming to be well structured, expandable, and easy to use without sacrificing any functionality.
Main features:
Supports up to: 6 Images, 2 Videos, 3 Audio.
ANY can be set as reference, guide, or both. This is much more useful than the average user understands - I have not yet seen this support in any other workflow.
Latent Upscale and/or 2-Stage Generation
Intuitive settings/LoRA management for each stage.
1-4 steps LLM Prompt Enhancement
Subgraph contains a dashboard to generate / edit LLM's responses before they pass into the next stage.
Includes my personal 4-Step Ref2VA pipeline.
Step 1 Prompt Enhancement/Expansion: (Optional Step). Allows the LLM to interpret the user's prompt more verbosely and in relation to the reference materials. Catching/editing discrepancies here will yield much better results in next steps.
Step 2: Reference Analysis: Creates a detailed mapping of the references in relation to the Expanded Prompt. The resulting Reference Map is included as part of the context in the next steps.
Step 3: Creative Director: Considers Expanded Prompt + Reference Analysis to create a Creative Blueprint.
Step 4: Prompt Compiler: Conforms the Reference Map + Creative Blueprint into the H3 prompt structure
Includes my personal 1-Step FL2VA Prompt Enhance
The system prompt begins with base instructions, adding task specific instructions (T2VA / I2VA / FL2VA / L2VA)
The mode is detected automatically based on the state of Image 1 / Image 2.
You, the user, can easily add your own LLM instructions into this system as selectable options. Take a shot at making your own multi-stage pipeline!
Seamless video continuation option - idea taken from Seed Hunter workflow
