Extract YouTube transcripts (timestamped, multi-language, SRT/VTT/CSV/TXT export), expand channels/playlists, and generate AI summaries with topic-based chapters. Proxy-aware with auto anti-block retries.
YouTube watch URLs, Shorts URLs, video IDs, OR channel/playlist URLs (channel pages, @handles, or ?list= playlist links). Channels/playlists are expanded to their videos automatically (capped by maxVideos).
Direct mode only. Browser/auto modes were removed in 0.3.
Maximum number of videos to process in one run (across all URLs and expanded channels/playlists).
Preferred transcript language code (e.g. 'en', 'es', 'hi'). Auto-generated captions are used as fallback when this language is unavailable. Defaults to 'en' when omitted.
DEPRECATED in favor of preferredLanguage, kept for backward compatibility. Used only when preferredLanguage is omitted. Ordered list of language codes.
[ "en", "en-US", "en-GB", "a.en"]Additional fallback language codes used when preferred language is unavailable. Defaults to the preferred language when omitted.
Return timestamped segments and full text in output. Default true.
Generate an optional AI summary when a transcript is available. Requires an OpenAI-compatible API key (OPENAI_API_KEY + OPENAI_BASE_URL).
Model name used for optional summarization and chapter segmentation.
AI summary length. short = 3-5 bullets, medium = 5-8, long = 8-12.
Language for the AI summary, independent of the transcript language (e.g. 'es', 'fr'). Leave empty for the model default (usually matches transcript).
Use AI to group the transcript into topic-based chapters with title + start/end times. Requires includeSummary + an OpenAI-compatible key.
Output format. json = full structured dataset row (default). srt/vtt/csv/txt = also attach a formatted transcript string to the row (srt, vtt, csv, or txt text file body).
Number of exponential-backoff retries when YouTube returns a block/IP-ban (429-style) error. Each retry rotates the proxy when one is configured.
Truncate transcript text/segments after this many characters.
Proxy for transcript fetching and channel/playlist expansion. Defaults to Apify RESIDENTIAL proxies (YouTube blocks datacenter IPs, so residential is required for reliable bulk/channel runs). Set useApifyProxy:true + apifyProxyGroups:["RESIDENTIAL"], or supply your own proxyUrl. Leave empty to use the residential default.
