ComfyUI

ComfyUI provides a visual node editor for building and debugging generative workflows. For a filmmaker, its practical value is making the steps of a process explicit: load the intended models and references, run a generation, and inspect the result before continuing. It is not a guarantee of a particular visual result.

Hardware needs depend on the chosen model, resolution, precision and workflow. There is no universal 12GB GPU minimum for the application. The official installation documentation describes multiple hardware options, including slower CPU execution. A workflow that opens successfully may still be too demanding for useful production speeds.

Local installation and hosted Comfy Cloud are different options. Local workflows can avoid a hosted-generation bill, but hardware, electricity and maintenance still cost money. Hosted services and API-backed nodes have their own pricing, connectivity and data policies. Check these before using client material.

A saved workflow helps reproduce the setup, not necessarily identical pixels across changed models, software versions or hardware. Record dependencies and test after updates. Check the licenses of the specific models, custom nodes and source assets rather than treating the application as a blanket commercial-use permission.
