Video Tool CLI

AI-powered video processing toolkit with ffmpeg operations, Whisper transcription, and content generation.

Installation Status

video-tool: !which video-tool > /dev/null && echo "INSTALLED" || echo "NOT INSTALLED - run installation below" uv: !which uv > /dev/null && echo "INSTALLED" || echo "NOT INSTALLED"

If video-tool is not installed, run the installation commands below before proceeding.

Installation

Install uv first (if not installed)

curl -LsSf https://astral.sh/uv/install.sh | sh

Install video-tool

uv tool install git+https://github.com/alejandro-ao/video-tool-cli.git

Dependencies ffmpeg: Required for all video operations (brew install ffmpeg on macOS) yt-dlp: Required for video downloads (brew install yt-dlp on macOS) API Keys Setup

Configure API keys (choose one method):

Option 1: Non-interactive (recommended for Claude Code)

video-tool config keys --set groq_api_key=YOUR_KEY video-tool config keys --set openai_api_key=YOUR_KEY

Multiple at once:

video-tool config keys --set groq_api_key=xxx --set openai_api_key=yyy

Option 2: Edit credentials file directly If users prefer not to share keys with Claude Code, they can edit directly:

File: ~/.config/video-tool/credentials.yaml

openai_api_key: sk-xxx groq_api_key: gsk_xxx bunny_library_id: xxx bunny_access_key: xxx replicate_api_token: xxx

Option 3: Interactive setup

video-tool config keys

Required keys:

groq_api_key - Transcription (Whisper) openai_api_key - Content generation (descriptions, timestamps)

Optional keys:

bunny_library_id, bunny_access_key - Bunny.net CDN uploads replicate_api_token - Audio enhancement video-tool config keys --show # View configured keys (masked) video-tool config keys --reset # Clear all credentials

IMPORTANT: Handling Authentication Errors

When a command fails with "AUTHENTICATION REQUIRED" or "API key not configured":

DO NOT try to work around the issue by writing custom scripts DO NOT try to call APIs directly INSTEAD, offer the user two options using AskUserQuestion:

Option A: Provide key to Claude (convenient)

User gives you the API key directly You run: video-tool config keys --set KEY_NAME=VALUE Faster, but the key is visible in the conversation

Option B: User configures privately (more secure)

User runs the command themselves or edits the file directly Key never appears in the conversation with Claude Tell user to run: video-tool config keys (interactive) Or edit: ~/.config/video-tool/credentials.yaml

Example AskUserQuestion prompt: "This command requires a [Groq/OpenAI] API key. How would you like to configure it?"

Option 1: "I'll provide the key" - convenient but key visible to Claude Option 2: "I'll configure it myself" - more private, key stays hidden from Claude

After user configures (either way), retry the original command.

Commands that require API keys:

video-tool generate transcript → Requires Groq API key video-tool video timestamps -m transcript → Requires OpenAI API key (structured output) video-tool upload bunny-* → Requires Bunny.net credentials video-tool video enhance-audio → Requires Replicate API token Content Generation: CLI Commands vs Direct Generation

Some CLI commands use OpenAI to generate content. When Claude runs this skill, it's often better for Claude to generate content directly instead of calling another LLM.

Use CLI command (requires OpenAI API key): video timestamps -m transcript - Uses structured output for precise JSON Generate directly as Claude (no OpenAI needed):

For these tasks, read the transcript/timestamps and generate content using the linked templates:

Description: See templates/description.md SEO Keywords: See templates/seo-keywords.md LinkedIn/Twitter Posts: See templates/social-posts.md Context Cards: See templates/context-cards.md Note on CLI commands

The CLI has commands like generate description, generate context-cards that use OpenAI. These exist for manual CLI usage. If user explicitly requests a CLI command, honor the request (it may require OpenAI key). Otherwise, generate content directly.

Output Location

Before generating files (transcripts, descriptions, timestamps, etc.), if not especified before, ask the user where to save them using AskUserQuestion.

Example prompt: "Where should I save the output files?"

Option 1: "Current directory" - save in . or ./output/ Option 2: "Same folder as video" - save alongside the source video Option 3: "I'll specify a path" - user provides custom location

Default behavior if user doesn't specify: Ask rather than assuming temp directory.

video-tool config youtube-auth
