I was under the impression you were referring to switching PLAYBACK from multiple source files, not from multiple running cameras. Kdenlive can take input from one  camera, no idea if it can do multiple cameras, as I've only used that feature for a webcam. I don't own pro cameras, only the $300 kind, as all my activist work is posted under strict no-monetization principles for ethical reasons.
