Video Caption Scraper - Multi-Platform Video Caption Extraction API

Video Caption Scraper is a multi-platform video caption extraction API that extracts native subtitle tracks, timestamped JSON segments, and SRT-converted output across 1,000+ video platforms in 55+ languages in a single video-URL-driven run. Video Caption Scraper returns structured records per video, including video URL, video ID, video title, video description, author/channel name, source platform, video duration in seconds, available subtitle language array, selected language code, native subtitle format (VTT/ASS/TTML/SBV), SRT file URL hosted on Apify key-value store, timestamped JSON segment array (start, end, text), thumbnail image URL, and ASR fallback flag when native captions are unavailable. Coverage spans YouTube, TikTok, Vimeo, Bilibili, Dailymotion, Twitch VOD, and 1,000+ additional platforms supported by the underlying extractor. Built for AI training corpora construction, video-localization pipelines, accessibility compliance toolchains, content-search indexing, video-summarization workflows, and multilingual-research datasets. Per-video pay-per-result pricing at $0.48 with no monthly minimum.

Multi-Platform 55+ Languages Pay Per Result

Why Choose This API

Structured Caption Data for AI & Localization Pipelines

🌐 1,000+ Platform Coverage Extract subtitles and captions from YouTube, TikTok, Vimeo, Dailymotion, and 1,000+ additional video platforms — enabling cross-platform caption intelligence from a single consistent API endpoint.

🌍 55+ Language Support The languages input parameter supports 55+ languages including English, Spanish, French, German, Chinese (Simplified and Traditional), Arabic, Hindi, Japanese, Korean, and more — with an "all" option to extract all available subtitle tracks simultaneously.

⏱️ Timestamped Caption Output The subtitle object provides timecode-keyed caption segments (e.g., "00:00:01,000 --> 00:00:03,500": "text") — enabling precise speech-text alignment for AI training data, automatic translation workflows, and accessibility engineering.

📄 SRT File Export The srt_url field provides a direct download link to the generated SRT subtitle file — enabling drop-in integration with video players, subtitle editors, and localization management systems.

🔄 Multi-Format Auto-Conversion Native caption formats (VTT, ASS, TTML, SBV) are automatically converted to standardized SRT and timestamped JSON — eliminating format normalization overhead in downstream ingestion pipelines.

Use Cases & Applications

AI Training Data & NLP Pipelines

Speech-Text Alignment Dataset Construction The timestamped subtitle object provides precise speech-text alignment data across 55+ languages — enabling multilingual ASR model training, subtitle quality evaluation, and cross-language alignment corpus construction for NLP research and AI training pipelines.

Multilingual Corpus Building Extract subtitles across multiple languages for the same video — building parallel translation corpora, language model fine-tuning datasets, and multilingual NLP training sets from video content at scale.

Localization & Accessibility Engineering

Video Localization Pipeline Extract native subtitle tracks in source language, feed timestamped segments to translation APIs, and re-import translated SRT files — building end-to-end video localization pipelines for content internationalization.

Accessibility Caption Generation The srt_url download link provides ready-to-use SRT files for closed caption editors, accessibility compliance workflows, and video platform caption upload pipelines.

FAQ

What video platforms are supported?

This actor supports 1,000+ video platforms including YouTube (all formats: standard, Shorts, live), TikTok, Vimeo, Dailymotion, and many others. Any platform that hosts subtitle/caption tracks can be extracted.

What subtitle formats are supported?

Native formats (VTT, ASS, TTML, SBV) are automatically converted to SRT and timestamped JSON. The srt_url field provides an SRT download link; the subtitle field provides the timestamped JSON representation.

Can I extract all languages at once?

Yes — set languages to ["all"] to extract every available subtitle track. Each language track produces one separate record in the output dataset.

Is there an ASR fallback for videos without subtitles?

Yes — for videos without native captions, the actor falls back to ASR (automatic speech recognition) transcription to generate subtitle content.
