ForRAG Pipelines

Video-first retrieval, without the infra bill

A cleanly-normalized transcript is the hardest part of a video-RAG system. We do that part — for YouTube, TikTok, Instagram, Facebook, X, Rumble, Vimeo, Dailymotion, and Loom — at unit economics that make indexing 100k videos actually feasible.

What is VidNavigator for RAG pipelines?
VidNavigator for RAG pipelines is a video-first ingestion and retrieval layer that converts any video URL into timestamped transcript segments, normalized across nine platforms and ready for your chunker, embedder, and vector database. Per-transcript pricing can be as little as $0.000025 on the $300 credit pack, keeping per-video cost near zero so video RAG stays economically viable at scale.

Where VidNavigator fits in your pipeline

1

Ingest

POST a video URL. Receive segmented transcript JSON with start / end timestamps, language, and metadata. Nine platforms covered behind one endpoint, 99+ languages supported, one consistent response shape whether the source is captioned or not.

2

Chunk

Our segments are naturally 2–4 seconds each — small enough for any chunker. Group them into 300–600 token windows with overlap and carry {video_id, start_sec, end_sec} as metadata on every chunk.

3

Embed

Plug into text-embedding-3-large, voyage-3, BGE-M3, or whatever your stack runs today. We deliberately return normalized plain text so embedder quality is the only moving piece.

4

Retrieve

Index in pgvector, Qdrant, Pinecone, Weaviate — whichever already lives in your stack. Your retrieval layer pairs naturally with BM25 because spoken content benefits from hybrid search.

5

Ground

Timestamps carry through every stage, so your generation prompt can cite [video_id:start_sec] and your UI can render a deep-link back into the exact second that produced the answer.
