Upload an MP4 (also MOV, WebM, M4V, OGV) in the Videos tab, then set any
      screen to Video mode and pick it. It plays full-screen with
      object-fit: contain and its own audio; room music
      auto-mutes while a screen is on Video, the same way it does for Presentation.

      This is how you show a deck's animations. Slides are flattened to
      images (no animation). To keep builds, transitions and embedded video, export the deck
      to MP4 in PowerPoint (File → Export → Create Video) and upload that here: it
      plays exactly as authored. Live Share is the other route (the presenter runs the real
      PowerPoint); Video is the unattended, file-based one.

### Operator controls

Control | What it does |

Video picker | Which uploaded file this screen plays |

Play / Pause | Autoplays when first put on a screen; pause and resume from the card |

Restart | Jump back to the start and play |

Seek | Slider scrubs to any point |

Loop | Repeat the file when it ends |

      Autoplay with sound relies on the one-time Start Display click on each
      screen: the same gesture music needs. A screen opened but never clicked plays the video
      silently. Uploads are capped at 400 MB per file.

      Controls target one screen. The same video on two screens plays independently and can
      drift out of sync: for a single controlled playback, put it on one screen.
