I have to begin this post with a massive note of gratitude to all the folks who've built this amazing programme and who support it on this forum. That said, I too, as a new user, fell prey to the confusion of the meaning of "Profile". I initially wanted to create a separate profile for my fitness teachers who are streaming classes from home using a single webcam vs those who are streaming classes from our special studio that has a multi-camera setup.
My error...I first created a "Studio" profile and created a few scene collections in the profile, each of which had different Intro's but the same multi camera switching sequences. I then duplicated that profile and renamed it "Home", and then within each collection there, deleted some superfluous cameras as the "home" users would only be using a single one. Lo and behold, I found those changes to the Scene Collections had also applied to the "Studio" Profile, so all my multi camera switching was deleted (no biggie as I'm just testing now).
Reading this thread explains what happened and what the solution is for me. As we'll be broadcasting only via a single platform (Vimeo OTT), I realise now that all we need is one profile that can be used by both the "Studio" based instructors as well as the "Home" based ones. In that one profile, each collection will be named "HOME - Lesson x" or "STUDIO - Lesson X". The instructor upon commencing will simply go into that profile and select the Scene Collection that applies to his or her class.
I realise this post is longer than needed, but hopefully it makes sense?
