Our review
Summarizes videos from local .mp4 files or online sources (YouTube, Bilibili) by extracting embedded subtitles or using Whisper AI for transcription, then generates a structured Markdown summary.
Strengths
- Supports long videos (over 40 minutes) with chunked processing.
- Uses embedded subtitles when available, otherwise Whisper AI for accurate transcription.
- Produces a structured summary along with transcript and info files.
Limitations
- Requires Whisper AI for videos without subtitles, which can be slow and resource-intensive.
- May fail if the video file is corrupted or the link is inaccessible.
- Summary quality depends on transcription accuracy (accent, noise).
Use this skill when you need a written summary of a video, whether local or online, without watching it in full.
Do not use it if you need detailed visual analysis (charts, graphics) or if the video is in a language not supported by Whisper.
