Role Description Multimodal Analysis Framework (MAF) is an end‑to‑end platform designed to process diverse content sources—including video, images, audio, and documents—to generate rich, structured metadata. The platform unifies multiple ML/AI models to extract curated insights at scale, tailored to specific business needs. MAF supports both on‑demand workloads (batch uploads, ad‑hoc analysis) and real‑time streaming workflows, enabling continuous metadata generation for live content streams. Customers can define their metadata requirements—such as entity extraction, scene segmentation, object detection, transcription, summarization, or multimodal correlation—and the framework orchestrates the appropriate models and toolchains to deliver high‑quality outputs. Through flexible APIs and UI‑based workflows, customers and internal teams can visualize metadata, trigger enrichment, monitor processing, and integrate results into downstream applications.
