Hi

I'm new here and want to ask if anyone can help on this issue.

I'm trying to put a scoreboard on top of a live feed in Vmix and want to show transparent (dynamic) graphics.
Is it possible to send a signal with alpha channel (NDI??) from the browser to Vmix?

As of now I only input the browser page and key the background color out, but this results in ugly artefacts on some graphics.

Thanks for the help.
Best regards from Germany

Yes.

Both SDI and NDI can use transparancy information.

thanks for the info, but I know, that NDI can use transparency, but how can I get transparent graphics from a browser window over into Vmix?

Sure if the web page has a transparent background.

Here is a google web designer demo

if you use the native browser/webpage input in vmix and simply have no background in your webpage it is then automatically transparent

SDI does NOT contain any alpha info.

Thank you so much for your information and tipps.
I will try to figure out a way to integrate the Vmix browser into this project.
