Building a Disk-First Production Pipeline in ComfyUI

The author shares their experience building a long-form AI video production pipeline using ComfyUI, shifting away from giant node graphs to a modular, disk-first architecture.
Architecture Highlights & Benefits:
- Solves Memory Bottlenecks: Avoids the "Rampocalypse" (memory explosion) from long render queues by checkpointing results from every expensive stage to disk, allowing crash recovery.
- Dependency Management: The controller tracks dependencies. Modifying an upstream keyframe only invalidates dependent downstream segments, eliminating the need to re-render the entire project.
- Dynamic Editing: Enables a "edit-while-rendering" workflow where assets are approved or re-rendered on the fly.
- Model Agnostic: Treats models as departments in the pipeline. Swapping underlying models (e.g., from Wan to MiniMax/H3) doesn't change the core architecture.
Performance:
Completed a 3m 5s film on an i9-9900K + 32GB RAM + RTX 3090 (38 keyframes, 37 video segments) with final assembly taking just 20 seconds. The architecture proved scalable for a separate 6-minute production.
