Connecting to broadcast tools

All supported tools can use the output URL as a browser source. The steps vary in naming but not in principle.

vMix

• Add → Web Browser.
• URL: the output's public URL.
• Width / Height: match the output's resolution.
• Background: transparent (check "Pre-multiply alpha" if colors look off).

OBS Studio

• Add → Browser.
• URL: the output's public URL.
• Width / Height: match the output's resolution.
• Custom CSS: leave blank.
• "Shutdown source when not visible": off — you do not want the graphics to reset every time the scene changes.

TriCaster

• Input → NDI (if OBS/vMix is sending NDI) or a network browser-source input if you have one.
• Key the output over the program feed with its alpha channel.

Wirecast

• Add media → Web Page.
• URL: the output's public URL.
• Enable transparency in the web-page source settings.

Troubleshooting

• Black background behind graphics — transparency is off on the browser source.
• Graphics flicker on scene change — "shutdown when not visible" is on; turn it off.
• Graphics look blurry — browser-source resolution is lower than the output.
• Graphics lag — the broadcast tool is CPU-bound; lower the browser-source framerate or run the tool on more powerful hardware.
