video-to-text-local

To transcribe video offline on Apple Silicon, this Skill extracts audio using yt-dlp and runs local mlx-whisper inference to generate text and SRT subtitle files entirely on-device.

Yes, you can generate SRT subtitles from a YouTube URL locally by passing the URL to the transcription function, which fetches audio via yt-dlp and processes it on-device with mlx-whisper.

On-device transcription with mlx-whisper does not require an internet connection for processing local media files, but fetching audio from YouTube URLs requires network access for the initial yt-dlp download.

The best way to create podcast transcripts privately is using on-device transcription, which processes local audio files via mlx-whisper to ensure data never leaves your machine or touches cloud services.

You can select a different mlx-whisper model for local transcription by setting the appropriate environment variable before running the Skill, allowing you to balance accuracy and performance.

Local video transcription fails with missing dependency errors when yt-dlp or mlx_whisper are not installed in your environment, which this Skill handles with robust error messaging to guide installation.
