🚧 Work In Progress 🚧 - ComfyUI nodes to facilitate value keyframing by providing an interface for using [keyframed](https://github.com/dmarx/keyframed) in ComfyUI workflows.

Similar project you might find more convenient for certain use cases https://github.com/FizzleDorf/ComfyUI_FizzNodes

# Overview

**Philosophy**

* Treat curves/schedules and keyframes as objects that can be passed around, plugged and unplugged, interchanged, and manipulated atomically.
* Leverage nodes to facilitate modularity and flexibility.
* Facilitate fast iteration
* Provide convenience functions for most common use cases, and also low-leverl operators capable of reproducing the behavior of those convenience functions to permit user customization in "node space".


# Starter Workflows

## Prompt Scheduling

![Prompt Scheduling](examples/prompt-scheduling.png)

 This one is probably why you are here. This workflow demonstrates how to use the `keyframed/schedule` nodes to achieve similar behavior as [FizzNodes'](https://github.com/FizzleDorf/ComfyUI_FizzNodes) **PromptSchedule** node, but implemented differently.

This schedule is essentailly a normal AnimateDiff workflow where several nodes have replaced the normal conditioning setup. Rather than a single `CLIP Text Encode` node, we can have multiple prompts which transition sequentially over time. For documentation detailing how this workflow works, see the `Nodes > Scheduling` section below.

## Prompt Interleaving (aka Prompt Entanglement, aka Prompt Superposition)

Which is the node equivalent for achieving this type of thing
