  • PrimeVideo XRay Clone

    A Python-based web application with a video ingestion pipeline that tags each frame in a video of a movie or a TV series with some metadata.

    This metadata included actors' names and could be extended to show other works from the actor. This tagged timeline was generated and the user might directly jump from one scene to another where the actor was present.
