Ingest and process media files (video, audio, image).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Ingest and track processing of media files (video, audio, images) through a configurable 3-phase pipeline. ## End-to-End Workflow The processing pipeline follows a sequential 3-phase flow: 1. **Ingest** (`ingest_media`) - Register a media file, detect MIME type, extract duration, deduplicate by content hash. 2. **Preprocess** (`extract_keyframes`) - Detect dead time, segment the video into windows, extract downscaled keyframes, build a subject registry, and write a pipeline manifest. 3. **Map** (`analyze_keyframes`) - Send each segment's frames to the configured Gemini vision model with assistant-provided extraction instructions and a JSON Schema for guaranteed structured output. Supports concurrency pooling, cost tracking, resumability, and automatic retries. 4. **Reduce / Query** (`query_media`) - Send all map output to Claude for intelligent analysis and Q&A. Supports arbitrary natural language queries about video content. 5. **Clip** (`generate_clip`) - Extract video clips around specific moments. The processing pipeline service (`services/processing-pipeline.ts`) orchestrates phases 2-4 automatically with retries, resumability, and cancellation support. ## Tools …

How to install
mdr add vellum-ai/vellum-assistant/media-processing@sha256:aa38b7020be5ef92The line at the top of this page pins the label git:20260903.5802532, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
