CorporaYouTube Video & Audio Datasets for AI Training, at Petabyte Scale
Corpora collects YouTube video, audio, subtitles and structured metadata for multimodal AI training — vision-language models, speech models and video LLMs. Choose 1–40 Gbps unmetered yt-dlp proxies to run your own pipeline, or let us deliver curated datasets straight to your cloud storage.
Multimodal training data from YouTube — video, audio, text and metadata
From raw video and audio streams to clean, structured metadata — collected at scale, deduplicated and organized for vision-language, speech and video-LLM training.
YouTube Video & Audio Download
Full-resolution video (up to 4K/8K), audio-only tracks for speech and music models, and selected formats. Delivered as original containers or transcoded to your target codec.
Structured Metadata
Title, description, tags, channel, publish date, duration, view/like counts, category, language and more — normalized to JSONL or Parquet.
Subtitles & Transcripts
Auto-generated and manual captions in all available languages, with timestamps aligned to the video for speech and multimodal training.
Comments & Engagement
Top-level comments, replies, like counts and reply threads, useful for conversational, sentiment and ranking datasets.
Thumbnails & Frames
All thumbnail resolutions plus optional keyframe extraction at custom intervals for vision-language pretraining.
Custom Targeting
Collect by keyword, channel list, playlist, topic, language, region, upload window or engagement thresholds. You define the scope.
