4brospix

4brospix is an experimental open-source AI animation production pipeline where Codex can control local generation workflows.

It connects story and shot manifests, AI image/video generation providers, ComfyUI/Wan-style workflows, Blender layout, CSP paint-over, After Effects compositing, and final render organization.

This repository is the public, sanitized starting point for the project. Private development and production experiments existed before this public repository, but private files, assets, machine details, credentials, logs, generated media, model weights, and production-specific paths are intentionally not included here.

Why It Exists

AI animation production involves many tools that do not naturally share a common structure. 4brospix explores a manifest-driven workflow where shots, prompts, references, provider jobs, review passes, layout data, paint-over notes, compositing outputs, and final renders can be organized without locking the project to a single vendor or local machine.

The goal is not to present a finished product. The goal is to make a public OSS lab notebook and workflow framework that can evolve safely.

Current Status

Early experimental.

This repository currently contains public documentation, sanitized examples, one Scene01 demo media set, and a small local automation script.

It does not include private source trees, raw internal workflows, credentials, model weights, production assets, logs, or machine-specific paths.

Scene01: Codex-Controlled LTX Video Generation

Scene01 is the first sanitized public case study.

GPT-generated image
  -> local Codex instruction
  -> Codex fills prompt/settings
  -> ComfyUI LTX single workflow
  -> generated tilt-up video

Status: successful internal test, sanitized public case study with a small input preview and one demo MP4.

The raw workflow JSON and private run scripts are not committed to git. The public package documents the workflow shape, includes a small input preview, includes one demo MP4, and provides template files.

Scene01 demo

Input image

Generated video preview

• 브라우저에서 Scene01 전체 데모 보기
• Scene01 출력 MP4
• Scene01 demo release asset

This repository includes one small demo MP4. Future generated demos should replace docs/media/scene01_output_demo.mp4 rather than adding many video files.

Pipeline

Story / Shot Manifest
  -> AI image/video generation provider
  -> Upscale / interpolation / cleanup
  -> Blender layout / camera / scene pass
  -> CSP paint-over
  -> After Effects compositing
  -> Final render organization

Provider-Agnostic Direction

4brospix should not hardcode one provider. A future implementation can model providers as adapters with shared concepts such as:

• comfyui
• wan
• future_openai_video
• runway
• kling

These names are conceptual examples only. This public repository does not include private endpoints, credentials, account data, internal workflow files, or provider-specific production settings.

What Is Intentionally Not Included

• Private source trees or scripts from earlier development
• Private IP addresses, hostnames, usernames, passwords, API keys, tokens, or .env files
• Internal server details or deployment notes
• Production assets, generated production media, final renders, or review media
• Model weights, checkpoints, LoRAs, embeddings, caches, or downloaded datasets
• Logs, temporary files, machine-specific paths, and editor state
• Proprietary provider workflows or account-specific settings

Exception: this repository includes one small public Scene01 demo MP4 at docs/media/scene01_output_demo.mp4. Future demo videos should replace this file rather than accumulate in git history.

Security Note

Treat this repository as public by default. Do not commit secrets, generated production media, provider credentials, private machine names, or internal paths. See SECURITY.md and docs/04_security_and_redaction.md.
