FAQ

Which platforms are supported?

Over 1000 platforms including YouTube, TikTok, Instagram, Twitter/X, Facebook, Vimeo, Twitch, and hundreds of additional video hosting sites.

What caption formats are supported?

The actor handles VTT, ASS, SSA, TTML, LRC, SRV1/2/3, SBV, and JSON3 formats. All non-standard formats are automatically converted to industry-standard SRT.

Can I extract captions in multiple languages?

Yes. Set the languages parameter to all to extract every available caption track, or specify individual languages like english, chinese_simplified, etc.

What happens if a video has no captions?

If no captions are available for the specified languages, the actor returns a record indicating no subtitles were found. The ASR fallback attempts to generate captions from the audio track when native captions are unavailable.

How is the subtitle dictionary structured?

Each subtitle entry uses the SRT timestamp format as key ("HH:MM:SS,mmm --> HH:MM:SS,mmm") mapped to the caption text as value. This format enables direct timestamp-based lookups in AI and search workflows.

Can I process multiple videos in one run?

Each run processes one video URL. For batch processing, use the Apify API to trigger multiple parallel runs or schedule sequential runs with a list of URLs.
