Shows & playout

Create a show, activate its output, and get each screen's private link into your switcher.

A show is a saved production with its own canvas, graphics list, edited values, data setup, scoreboard setup, and permanent playout URL. Saving changes updates that show; Duplicate creates an independent copy that starts off air.

Creating and activating a show

  1. 1Shows → New show.
  2. 2Set the canvas size to match your programme — 1920x1080 for HD, or anything custom for LED walls and side panels.
  3. 3Leave the background transparent so the graphic keys over your video. Give it a solid colour only if you want a full-frame card.

Use the Active toggle to assign one of your plan's clean output slots. If every slot is occupied, choose the active show to replace. An inactive show remains saved and its URL works with a large watermark.

Canvas size, transparency, and the show name can be changed later from Edit → Rename & settings.

Getting the picture onto a screen

Open Playout URL in your show. It has two tabs: Cloud (the default) and Local Hub (optional, for playing out over your venue network). On the Cloud tab every screen gets its own private link — a long, unguessable URL that belongs to one device. Below it, Pair a device lets tablets and portable switchers join with a 6-digit code from gfx.miri.tech/tv, and then the list of that tab's screens with their online status. Remove cuts a screen off instantly and its link stops working for good.

The control room's Camera / NDI® output window gets its own separate link, so it never clashes with a link you copied for another screen.

Paste a screen's link into your switcher or browser source:

  • vMix — Add Input → Web Browser, paste the URL, set the size to your canvas size.
  • OBS — Sources → Browser, paste the URL, tick “Shutdown source when not visible” off so it stays connected.
  • ATEM / hardware — feed it from any HTML5 media player or browser-capable device pointed at the URL.
  • Anything you cue and take in the Control Room appears on that page within a fraction of a second — no refresh needed.

Keep it private

Screen links are unguessable but public by design, so any device can load one without signing in — treat them like stream keys. Because each link belongs to a single screen, a leak is easy to fix: remove that screen and hand out a fresh link, without disturbing anything else.
