Run a teleprompter beside vMix

To run a teleprompter with vMix, open the NextPrompt Display link on the screen your talent reads from and fire the control URLs from vMix Scripting or shortcuts: play, pause, restart, and speed are each a plain HTTP GET. No plugin, no API key, and no extra hardware; the prompter syncs over the internet to every connected screen.

Step by step

  1. Put the reading screen where the talent looks. Open the Display link on the screen at the lens: a confidence monitor, a tablet on the rig, or a browser window on a spare output. It shows clean scrolling text and nothing else, and it needs no vMix input to work.
  2. Copy the Controller link. In NextPrompt's Share panel, copy the Controller link. The long random string in it is the share id that grants control; treat the link like a password.
  3. Fire control URLs from vMix Scripting. In vMix, create a script that performs an HTTP GET to the control URL for each action you want: play, pause, restart, or a speed change. Bind each script to a vMix shortcut so it fires from your keyboard, controller, or the vMix API alongside your other show control.
  4. Roll the prompter with the show. Trigger play as you roll the open, pause when the talent goes off script, and nudge speed as they settle in. Every action lands on the reading screen in real time, and a helper on the in-app Controller can take over at any point.

The URLs your scripts call

Replace the origin with the domain your NextPrompt links already use, and CONTROL_ID with the share id from your Controller link: 

.../api/nextprompt/share/CONTROL_ID/control?action=play
.../api/nextprompt/share/CONTROL_ID/control?action=pause
.../api/nextprompt/share/CONTROL_ID/control?action=restart
.../api/nextprompt/share/CONTROL_ID/control?action=speed&value=2.5
.../api/nextprompt/share/CONTROL_ID/control?action=speed&value=up
.../api/nextprompt/share/CONTROL_ID/control?action=speed&value=down

Speed takes an exact value from 0 to 5, or up / down for the same nudge as the on-screen arrows. A password-protected link needs &password=YOUR_PASSWORD appended.

Questions

Does NextPrompt integrate with vMix directly?

There is no plugin and none is needed. NextPrompt is a browser teleprompter that runs beside vMix, and its control actions are plain GET URLs that vMix Scripting and shortcuts can fire.

Can I show the prompter through vMix?

The Display link opens in any browser, so you can put it on any screen a vMix machine feeds. Most operators simply open it on the monitor or tablet at the lens.

What actions can vMix trigger?

Play, pause, restart to the top of the current Script, an exact scroll speed from 0 to 5, or a speed nudge up or down. Add the password parameter if the Controller link is protected.
