FAQPage Schema
How do I extract YouTube transcripts and subtitles from a video URL?▼

To extract YouTube transcripts, provide the video URL or ID to retrieve subtitle content via the DownSub API. This automates caption retrieval, replacing manual workflows for video research and content analysis.

Can I get timestamped captions instead of a plain transcript?▼

Yes, you can generate timestamped captions or plain transcripts to suit different content workflows. Optional timestamp formatting is supported alongside standard subtitle format handling during the extraction process.

Do I need a DownSub API key to retrieve YouTube captions?▼

Yes, DownSub API authentication is required to retrieve YouTube captions. You must configure your API credentials in the environment setup before extracting subtitles from video URLs or identifiers.

What is the best way to automate subtitle generation for YouTube video research?▼

Automating subtitle generation involves passing YouTube video links to the extraction script, which fetches caption content directly. This approach streamlines video research, summarization, and content repurposing tasks.

Does this YouTube transcript extraction method work with just a video ID?▼

Yes, the extraction method works with both full YouTube URLs and standalone video identifiers. The script parses the provided input to fetch and format the available subtitle content accurately.

Why are my YouTube subtitles not extracting correctly?▼

YouTube subtitles may not extract correctly if the DownSub API authentication fails or the URL parsing encounters an unsupported format. Ensure your API key is valid and the video identifier is correctly formatted.
