I Let AI Sound-Design My Edit (Free Skill)
This tutorial demonstrates how filmmakers can integrate custom LLM skills with ElevenLabs API to automate shot-by-shot sound design generation and build an interactive, taste-adapting SFX library.
What this lesson covers
The video presents a walkthrough of SFX Lab, an open-source tool connecting ChatGPT skills with the ElevenLabs API to automate audio sound design for video edits. Creator FRMWRKD-EXPLAINED demonstrates how to install the skill, configure API keys, generate initial sound effects, and let the AI agent analyze and sound-design a commercial shot by shot.

Rating generated sound effects with stars creates a self-improving taste profile that prioritizes existing high-rated sounds to optimize credit costs.
- 5:31 ↗
Inputting a finished film into ChatGPT prompts the AI agent to analyze shot transitions and automatically build a complete shot-by-shot sound design timeline.
Workflow outlined in the video
- Download and clone the open-source SFX Lab repository and load the skill into ChatGPT using slash commands.
- Obtain an API key from the ElevenLabs developer console and save it inside the SFX Lab browser interface.
- Generate an initial batch of test sound effects to build a base library inside the application dashboard.
- Review and rate generated audio clips using the star rating system to establish project-specific taste preferences.
- Upload a completed video edit to ChatGPT and prompt the agent to analyze the footage and construct a shot-by-shot sound design sequence.
- Audition alternative audio clips directly in the timeline interface using hotkeys to swap and refine sound placement.
