videopilot 0.1.2

Agent-driven video creation toolkit: neural TTS voiceover, highlight cutting, timeline composition, and NLE export.

videopilot

Agent-driven video creation toolkit. Neural TTS voiceover, AI highlight cutting, timeline composition with slides and audio ducking, and NLE export — all driven by a calling LLM through a JSON state contract.

videopilot is a Python CLI that turns raw screen recordings into narrated, edited MP4s. The CLI does the mechanical work — ffmpeg, neural TTS, faster-whisper transcription, timeline rendering. A calling agent (GitHub Copilot CLI, Claude Code, Continue.dev, or any code-aware LLM) does the creative work — writes the voiceover script, picks the highlight spans, lays out the timeline — by reading the contract in AGENT.md and authoring small JSON state files.

You can also drive videopilot by hand. Each subcommand is independently usable.

source.mp4  ->  script.json  ->  tts  ->  cut-plan.json  ->  cut  ->  compose-plan.json  ->  compose  ->  final.mp4
                                                                                                         + EDL / FCPXML / replay script

Incremental authoring from agents	Six convenience MCP tools for incremental authoring, schema introspection, preview rendering, and idempotency probing — see AGENT.md

Install

From PyPI (recommended)

pip install --user videopilot

videopilot is a console script — after install it's on your PATH. Verify:

videopilot doctor

You also need ffmpeg on PATH:

OS	Command
Windows	winget install --id Gyan.FFmpeg -e
macOS	brew install ffmpeg
Debian / Ubuntu	sudo apt install ffmpeg
Fedora	sudo dnf install ffmpeg
Arch	sudo pacman -S ffmpeg

videopilot doctor exits 0 when ffmpeg, ffprobe, Python deps, and optional Azure keys are all in order; otherwise it prints exactly what's missing.

From source (development)

git clone https://github.com/mbahgatTech/videopilot.git
cd videopilot
pip install --user -e .

Via the Agency plugin

If you use Copilot or Claude inside Microsoft and have access to the Agency Playground marketplace, install the videopilot plugin and ask:

set up videopilot

The plugin's init skill runs the same installer logic for you.

Quick start

# 1. Create a project with a source video
videopilot init demo --source "/path/to/raw-recording.mp4"

# 2. Hand-author projects/demo/script.json (one segment per beat of narration),
#    OR have your agent draft it from AGENT.md.

# 3. Synthesize the voiceover
videopilot tts demo

# 4. (Optional) transcribe to help pick highlights
videopilot transcribe demo raw1

# 5. Hand-author projects/demo/cut-plan.json (which spans to keep)

# 6. Cut clips from sources
videopilot cut demo

# 7. Hand-author projects/demo/compose-plan.json (timeline + slides + ducking)

# 8. Render the final video
videopilot compose demo

# 9. Optional: emit NLE projects + replay script
videopilot export demo --edl --fcpxml --script

Final output: projects/demo/out/final.mp4 plus optional final.edl, final.fcpxml, and render.ps1.

CLI reference

Configuration

Environment variable	Purpose
AZURE_SPEECH_KEY	Optional. Enables Azure Speech voices (premium neural TTS).
AZURE_SPEECH_REGION	Required when AZURE_SPEECH_KEY is set (e.g. eastus).

Edge TTS is the default and requires no configuration.

Driving videopilot from an LLM

Read AGENT.md. It is the contract the calling LLM uses:

• the JSON schema for each state file (project.json, script.json, cut-plan.json, compose-plan.json);
• when to call which subcommand;
• conventions (2-space JSON, preserved ids, idempotent re-runs);
• common failure modes and recoveries.

The videopilot plugin in the Agency Playground packages this contract as a Copilot/Claude skill so you can just say set up videopilot and make a video from <source> instead of orchestrating by hand.

Development

git clone https://github.com/mbahgatTech/videopilot.git
cd videopilot
pip install --user -e ".[dev]"

# Build the package
python -m build

# Validate the dist
python -m twine check dist/*

# Local smoke test
videopilot doctor

Releasing

Releases are published to PyPI automatically when a v* tag is pushed. The workflow uses PyPI Trusted Publishing (OIDC), so no API tokens are stored in the repo or in GitHub Secrets — PyPI verifies the GitHub OIDC token at publish time.

One-time setup (PyPI side, do this once before the first release):

1. Sign in to https://pypi.org/.
2. Account settings → Publishing → Add a new pending publisher:
   • PyPI project name: videopilot
   • Owner: mbahgatTech
   • Repository: videopilot
   • Workflow filename: release.yml
   • Environment name: pypi
3. On GitHub, repo Settings → Environments → New environment → pypi. Optionally add a required reviewer for an extra approval gate.

Cutting a release:

# bump pyproject.toml [project] version, e.g. 0.1.0 -> 0.2.0
git commit -am "release: 0.2.0"
git tag v0.2.0
git push origin main --tags

The release workflow then:

1. Builds sdist + wheel
2. Verifies tag matches pyproject.toml version
3. Runs twine check
4. Publishes to PyPI via OIDC
5. Creates a GitHub Release with the sdist + wheel attached
