Video Transcript Downloader

**Verdict:** Strong, focused utility skill for downloading videos/audio/subtitles and generating readable transcripts from YouTube and other yt-dlp–supported sites. Well-suited as the default tool whenever a user asks to download media or get a transcript from a URL, but depends heavily on external tools and carries legal/ToS considerations. **What it does well** - Wraps yt-dlp + ffmpeg + youtube-transcript-plus into a coherent interface for: - Clean paragraph transcripts (default), with options for timestamps and keeping bracketed cues. - Video/audio/subtitle downloads. - Format inspection and specific format selection, including remuxing to MP4 where possible. - Fallback logic: prefers official YouTube transcript API when available, then falls back to subtitles via yt-dlp and cleans them, which gives reasonably robust transcript coverage. - Advanced usage: arbitrary yt-dlp flags can be forwarded, enabling fine-grained control (e.g., format selection, verbosity, debugging) without changing the script. **Key risks / limitations** - **Legal & ToS risk:** Downloading or transcribing videos may violate platform terms of service or copyright laws depending on content and jurisdiction. Agents should avoid use on paid, restricted, or obviously copyrighted content unless rights/permissions are clear. - **External dependencies:** Requires working installations of Node/npm, yt-dlp, and ffmpeg. Breakage or absence of these tools (or outdated versions) will cause failures; troubleshooting steps (e.g., `brew install`) assume a macOS-like environment and may not generalize to all runtimes. - **Site and API fragility:** Any change in YouTube or other sites’ structures, or in youtube-transcript-plus/yt-dlp behavior, can break transcript or download flows until dependencies are updated. - **Content variability:** Some URLs offer no subtitles or transcripts at all, or only in certain languages; transcripts may be auto-generated with errors. Large/long videos can be slow to download and require significant disk space. **Recommended scenarios** - Default choice whenever users ask: “download this video/audio/clip”, “get subtitles”, or “get a transcript” from a YouTube or similar video URL. - Research, note-taking, or analysis workflows where a readable paragraph transcript is more useful than raw subtitle files. - Technical users or agents needing precise format control (resolutions, containers, separate video/audio) or remuxing to MP4 without re-encoding. Overall, this skill provides high practical value for media/transcript tasks, with main caveats around dependency health and respecting legal/ToS boundaries when downloading or transcribing online videos.
