Yes, you can extract subtitles from member-only Bilibili videos by providing access to your browser cookies, which allows the yt-dlp engine to authenticate your account and retrieve the restricted content.

To get a clean transcript from multi-language subtitle tracks, the extraction process parses formats like SRT, VTT, and JSON3, converting them into normalized plain text with timestamps for easy summarization and search.

You need yt-dlp installed to extract video transcripts, while ffmpeg is an optional dependency used specifically for format conversion when processing subtitle files from Bilibili or YouTube videos.

To extract transcripts from a YouTube playlist in batch, the process enumerates the playlist videos, extracts per-video subtitles, and produces an indexed output for downstream processing and timestamped search.

The best way to search through long video lectures by timestamp is to extract and normalize the subtitles into a parsed JSON3 or SRT text index, enabling timestamped search and summarization across the video content.
