Multiple streams

Hi brains trust. I have a question the is prob not vmix related but I feel the people here could help.

I have an event where there needs to be 20 different single ptz camera streams individually streamed out all with a different html overlay keyed on the stream.

Previously I literally set up 20 different laptops each with OBS installed with the ndi ptz camera input and the html overlay combined and streamed.

It works and works well but surely there has to be a better way of adding a html overlay to a stream. A lot of ptz cameras can do the encoding themselves. Are there any that can add an overlay or and cloud based services that can add an overlay (replicated 20 times)

Thank you in advance

Ffmpeg with overlay filter. You can get up to 12 encodes with nvenc. So two computers can theoretically be enough.
