Get the overlay link first: Show captions on a screen or in your video mixer explains where it is and which colours to pick.
- Click Add Input, open the Web Browser tab, paste the overlay link, set Width to 1920 and Height to 1080 and click OK.
- Use one of the four numbered overlay buttons under the input, or add the input as a layer over your program input in Input Settings. Either way the captions stay on top of the picture.
- Sound check: add
&preview=1to the end of the URL while testing and watch the input preview. Remove it once you see Receiving captions.
- Keep Background on Transparent on the Overlay link card. vMix keys on the page not painting a background, so a coloured one would cover the picture. Transparent makes the page see-through, but the box behind the words stays. To show just the letters, set Text background to 0 under Settings → Screens, usually with a Text outline so they stay readable.
- The input keeps its connection while it is off program. There is no need to remove and re-add it between services.
