OutOcut

AI-friendly video editor - The CLI tool for motion graphics and video editing.

Made by BLOUplanet

Philosophy

OutOcut is built on a simple premise: video editing should be as easy as writing code.

Every aspect of your project is data. Every animation is reproducible. Every frame is deterministic.

Core Principles

• Everything is a Layer - Video, audio, text, shapes, images - all are layers
• Everything is Keyframable - Time, value, easing - all can be animated
• Everything supports Expression - Use JavaScript-like expressions (position.x = time * 50)
• Composition First - Infinite pre-composition nesting
• Deterministic Render - Same JSON = 100% identical output
• Vector-first - Resolution-independent motion graphics with Cairo

Installation

curl -sSL https://raw.githubusercontent.com/llaa33219/outocut/main/install.sh | bash

Or install from source:

git clone https://github.com/llaa33219/outocut.git
cd outocut
cargo build --release
sudo mv target/release/outocut /usr/local/bin/

Quick Start

1. Create a Project

outocut validate my-project.outocut

2. Render to Video

outocut render project.outocut -o output.mp4

With GPU acceleration:

outocut render project.outocut -o output.mp4 --gpu

With custom quality settings:

outocut render project.outocut -o output.mp4 --preset slow --crf 18

3. Preview

outocut preview project.outocut --time 5.0

4. Watch Mode

outocut watch project.outocut

CLI Commands

Command	Description
render	Render project to video file
preview	Preview project at specific time
validate	Validate project file
export-json	Export JSON with optional formatting
watch	Watch for changes and auto-reload

File Format

OutOcut projects are pure JSON files with .outocut extension. They support comments:

{
  // This is a comment
  "version": "1.0",
  /* Multi-line
     comment */
  "settings": {
    "width": 1920,
    "height": 1080,
    "fps": 30
  }
}

See File Format Specification for complete documentation.
