I read this: MP4 / h.264 patent issues? - Video Production Stack Exchange
As usual with anything involving patents it’s murky, but I did get half the idea, that VCV:Recorder being distributed for free actually might let both Andrew and users off the hook, since licensing is primarily about outfits using these capabilities on a big scale to make money, but I’m definately not a lawyer, nor do I ever want to be one
