📺 YouTube Transcript Scraper — Full Captions, Subtitles & Auto-Generated Text

Extract the full transcript of any public YouTube video — auto-generated or human-uploaded captions, per-segment timestamps, language detection, and multi-language fallback. Built as a pay-per-result alternative to YouTube Data API v3 captions endpoint (OAuth-gated + quota-burning), Rev.com ($1.50/min human transcription), Otter.ai ($16.99-30/mo), Whisper-as-a-service tools, and manual download-and-parse for content research, NLP training, and accessibility workflows.

Why YouTube Transcript Scraper Beats YouTube API, Rev, Otter & Whisper SaaS

Feature	NexGenData YouTube Transcript Scraper	YouTube Data API	Rev.com	Otter.ai	Whisper SaaS
Cost	$0.005 / video, pay-per-result	OAuth + quota	$1.50 / minute	$16.99-30 / month	$0.006-0.02 / min
Per-segment timestamps	Yes	Yes (XML)	Yes	Yes	Yes
Language detection + fallback	Yes — auto + manual fallback	DIY	English-first	English-first	Auto
Auto-generated captions	Yes — pulled directly from YouTube	Plan-gated	N/A (human only)	N/A (own audio)	Re-transcribed
Speed	1-3 sec per video	API-quota dependent	Hours	Real-time only	Minutes
Bulk batch	Yes — video-ID list	DIY	One-by-one	One-by-one	API batch
Auth required	Apify token	OAuth + API key	Account + payment	Account + plan	API key
Monthly minimum	None	None (quota walls)	None	$16.99+	None

Most content + NLP teams pick this actor instead of YouTube's official caption API because the API's quota costs eat through 10K daily units inside 20 videos. Cheaper than Rev.com by 100-1000× for English videos (since the captions already exist on YouTube) and a drop-in alternative to Whisper-as-a-service when you don't need to re-transcribe audio that's already captioned.

What You Get Per Video

• video_id, video_url, video_title, channel, published_at, duration_seconds
• language_detected, language_requested, is_auto_generated
• transcript_plain — full text, no timestamps, ready for NLP
• transcript_segments — array of {start, duration, text} for word-by-word timing
• transcript_word_count, transcript_char_count
• available_languages — list of all caption languages on the video
• error — if no captions available

Use Cases

• AI / NLP training — bulk-export labeled transcript corpora for fine-tuning
• Content repurposing — turn YouTube videos into blog posts, newsletters, social clips
• Accessibility — generate full text-of-video for screen-reader or low-bandwidth audiences
• SEO / content research — extract every spoken keyword from competitor videos for content gaps
• Podcast / lecture archives — build searchable, full-text indexes of long-form video content
• Subtitling / translation — pull the source captions, then run them through your translation pipeline
• Compliance / monitoring — audit channel transcripts for regulated content

Quick Start (Python)

from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("nexgendata/youtube-transcript-scraper").call(run_input={
    "video_urls": [
        "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
    ],
    "language": "en",
    "include_segments": True
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["video_title"], item["transcript_word_count"])

Pricing — Pay Per Video

• Actor start: $0.005

FAQ

Q: Does it need a YouTube account or API key? A: No — it uses YouTube's public caption endpoints. Zero setup beyond pasting video URLs.

Q: What if the video has no captions? A: The actor returns error: "no_captions_available". For audio-only re-transcription, pipe the video through a Whisper or Deepgram actor instead.

Q: Auto-generated vs human captions? A: Both are supported. is_auto_generated: true flags ASR captions; manually uploaded captions are higher quality when available.

Q: Language fallback? A: If the requested language isn't available, the actor falls back to the default caption language and flags the swap in language_detected.

Q: Maximum video length? A: No hard cap. Multi-hour lectures and podcasts (4-8h) work fine; expect 5-10 sec per video runtime.

How NexGenData Pricing Works

Every NexGenData actor uses pay-per-event pricing — you only pay for results that actually land in your dataset. No monthly minimum, no seat fees, no surprise overage bills.

• Actor Start: a single-event charge each time you spin the actor up (scaled to memory size)
• Result / item: charged per item written to the default dataset
• No charge for retries, internal proxy rotation, or failed sub-requests — those are absorbed by the platform
