video-transcript

To extract verbatim transcripts from Bilibili, Douyin, and Xiaohongshu, this process uses a headless browser pipeline with Playwright to fetch streams and the Doubao API to generate accurate, timestamped text. It handles automatic segmentation for long videos to prevent summarization.

Yes, you can get a searchable transcript with timestamps from local video files. The system downloads streams via yt-dlp, compresses videos to API limits, and outputs timestamped, readable Markdown transcripts to local files for archiving.

The best way to transcribe long videos without summarization is through automatic segmentation. The pipeline splits long videos into smaller chunks and processes each segment individually to maintain strict verbatim fidelity across the entire duration.

Yes, you need a provided Doubao API key to perform video transcription. While Playwright handles headless browser extraction and yt-dlp manages stream downloads, the Doubao API executes the actual speech-to-text conversion for the final transcript.

Video transcription can fail if videos exceed API limits without prior compression. The system mitigates this by compressing videos to fit API constraints before calling the transcription service, ensuring large local files or long YouTube streams process correctly.

Yes, yt-dlp works with headless browsers to extract transcripts across multiple platforms. Playwright manages the headless extraction pipeline locally without requiring site logins, while yt-dlp downloads the video streams for transcription.
