This is absolutely correct, VMix is excellent software. When you pair it with the correct hardware even low cost hardware, it is very stable and reliable (and powerful). it’s also very reasonably priced, for one particular client twice a year I do a large 2 to 3 day livestream. We buy two copies of their $50 a month pro version (by default it is not a reoccurring subscription), each event. Every aspect of vmix can be automated or scripted, and they have a very easy to use XML based API (I can code but I’m definitely not a coder). Over the years we’ve built some incredible automated graphics for displaying on large billboards at the event, as well as using the second copy to produce the livestream where we pull in five professional ptz cams (via rtsp) and 2x sdi video feeds (via a capture card). We also use the NDI app on two iPhones to add their video into the mix (using the built-in vmix scripting, when someone presses the send button in the NDI app, V-Mix notices the audio level going above zero, and switches that live video feed into program). Note to do ndi over iphone wifi we use a dedicated ruckus R610 access point with no other clients on it, the video has ZERO latency, and amazing 4k quality). We also use companion running on a raspi5, connected to 2x stream decks, so that the entire set up can be controlled via the stream deck buttons.
