I shot scenes for a roughly 2-minute video that I'm using as a proof of concept for work. Part of what I'm wanting to accomplish is illustrate that "I need more tools to [do this thing]," which in this case is making/editing videos.

I'm removing the backgrounds from every shot and would like to replace the largely-empty background I've removed with a better-looking corporate office setting. Essentially, the same room layout but different.

What would be my best tool(s) for creating this?

I essentially want to be able to embed a stream of myself (thru OBS) onto a personal website without relying on external services like YouTube, Kick, or Twitch.

I do not expect large audiences, but somehow integrating IRC chat would be great.

Might anyone point me in any direction I'd need to start to accomplish this?
