Custom AI Video Captioning: Whisper-Powered Transcription
This skill facilitates the addition of timed, styled captions to finished videos using local resources, avoiding the need to re-render the source video. It provides a manual fallback option for scenarios where automated API endpoint captioning is unsuitable.
What this skill does
- Transcribes audio from a finished MP4 video with speech using Whisper technology.
- Groups transcribed words into readable phrases.
- Renders captions in a web browser environment via HyperFrames.
- Composites captions onto the source video using ffmpeg with a real alpha channel.
- Operates entirely on local machines, consuming no API credits and requiring no API key.
- Ensures the original video pixels and audio remain untouched, only adding captions on top.
Who it is for
This skill is designed for developers and teams utilizing AI coding agents like Claude Code, Cursor, and Codex. It is particularly useful for those needing to apply customized video captioning to their outputs.
Use cases
- Applying customized captions to videos where API presets are insufficient or need manual correction.
- Adding captions to videos where audio was disabled during rendering and automated APIs are not applicable.
- Creating TikTok-style captions or word-by-word text animation for enhanced visual storytelling.
Technical details
- Uses Whisper for audio transcription and HyperFrames for rendering captions in a browser environment.
- Employs ffmpeg to composite captions over the source video with proper alpha channel handling.
- Runs independently of the API, eliminating the usage cost associated with API calls.
