Hello.

Is there an option to combine some background pre-recorded video with live stream which has green background (green studio / chroma key) so that green turns into transparent and live video gets overlayed over background video?

Is it possible with any built-in wowza tools or via custom module?

Any tutorials?

Thank you.

Hey @Vasily Enot,

I dont know if Wowza has any built in tools but I bought a piece of hardware which could be what you’re looking for.

I’ve been using a Pearl 2 by Epiphan Video for streaming live shows where I use the Chromakey feature and it has been working very well for me. It’s very easy to use and very resilient!

Cheers,

Phil
