System Requirements Document

1. Introduction

This document outlines the system requirements for the "Some Wack Comedy" animation pipeline project. The project leverages various technologies to create a streamlined process for character animation using GIFs, stickers, and memes. The pipeline integrates several tools and platforms to facilitate AI-driven character animation and motion generation.

2. System Overview

The "Some Wack Comedy" animation pipeline is designed to automate and enhance the process of character animation. It utilizes Cartwheel AI for animation and motion generation, integrates with After Effects for pose-preset UI, and employs Hugging Face models for pose estimation. The pipeline is modular, with components hosted on Replit, and is intended to be archived and referenced within the 8080.ai knowledge base.

3. Functional Requirements

Character Pose Extraction

• As an animator, I want to extract character poses from GIFs, stickers, and Adult Swim reference clips, so that I can use them as animation references.

After Effects Plugin

• As an animator, I want an After Effects plugin that provides a pose-preset UI similar to Daz Studio, so that I can easily apply and manage character poses.

Pose Estimation Model Integration

• As a developer, I want to integrate Hugging Face pose estimation models, so that I can accurately extract and apply character poses.

Modular Replit Micro-Apps

• As a developer, I want to use modular Replit micro-apps for pose parsing, masking, SVG export, and morph generation, so that I can manage different aspects of the animation pipeline efficiently.

AI-Driven Character Animation

• As an animator, I want to use Cartwheel AI for AI-driven character animation and motion generation, so that I can automate repetitive tasks and enhance creativity.

Background Removal

• As a developer, I want to remove backgrounds from character images using the rembg library, so that I can isolate characters for animation.

Anchor Point Mapping

• As a developer, I want to map anchor points on character images, so that I can ensure accurate pose application and animation.

Metadata Injection

• As a developer, I want to inject metadata into PNG files and write sidecar JSON files, so that I can preserve character specifications and facilitate future reference.

Batch Pose Duplication

• As a developer, I want to apply pose templates and overrides to generate multiple pose variants, so that I can efficiently create diverse character animations.

Pipeline Orchestration

• As a developer, I want to orchestrate the animation pipeline stages (background removal, anchor mapping, metadata injection, pose duplication), so that I can automate the animation process for multiple characters.

Animation Decisions

• As a project manager, I want to document animation decisions made during the Cartwheel session, so that I can ensure consistency and alignment with project goals.

Cartwheel Settings Documentation

• As a developer, I want to document any Cartwheel settings, model parameters, or configurations used during the session, so that I can replicate the setup in future sessions.

Export Format

• As an animator, I want to specify the export format for animations, so that I can ensure compatibility with other tools and platforms.

Export Destination

• As a developer, I want to define the export destination for pipeline outputs, so that I can organize and manage files efficiently.

Frame Rate

• As an animator, I want to set the frame rate for animations, so that I can control the timing and smoothness of motion.

Loop Type

• As an animator, I want to specify the loop type for animations, so that I can create seamless or one-shot animations as needed.

Next Step in Pipeline

• As a developer, I want to outline the next steps in the pipeline after each stage, so that I can ensure a smooth workflow.

Pipeline Integration Notes

• As a developer, I want to document how Cartwheel's output connects to the rest of the pipeline, so that I can maintain integration and data flow.

Reference Source

• As an animator, I want to specify the reference source for poses, so that I can ensure accuracy and consistency in animations.

Resolution / Scale

• As an animator, I want to set the resolution and scale for animations, so that I can maintain quality and detail.

Rig Type

• As an animator, I want to define the rig type for characters, so that I can apply appropriate animation techniques.

Technical Outputs

• As a developer, I want to list any technical outputs generated during the Cartwheel session, so that I can track and manage files.

Unresolved Questions / Follow-Up Items

• As a project manager, I want to list unresolved questions or follow-up items from the Cartwheel session, so that I can address them in future meetings.

Apply dx/dy Overrides

• As a developer, I want to apply dx/dy overrides to anchor points, so that I can adjust poses accurately.

Flip & Scale

• As a developer, I want to apply flip and scale transformations to character images, so that I can create diverse pose variants.

Model Parameters

• As a developer, I want to configure model parameters for pose estimation, so that I can optimize accuracy and performance.

Output Path

• As a developer, I want to define the output path for generated files, so that I can organize and retrieve them easily.

Per-Anchor dx/dy Overrides

• As a developer, I want to apply per-anchor dx/dy overrides, so that I can fine-tune individual anchor positions for poses.
