So separating audio, I can meant from the video itself. We already support separate audio channels (which is how we do multiple languages for our big shows) but ...
It would take work for streaming software & Xbox to split it before it comes to us, which is doable, just takes time &making it priority
That's the cost I don't want to pass on. Right now people have to set it up, which cost time, but it doesn't cost them actual dollars.
But we agree on so much! I think that it totally makes sense for Mixer to do it. We resources available to help, it would be something to totally show off, etc etc.
So that would be the next area of captioning we worked on (although I don't have a timeline available)
Again, I would love to have automated captions as you described, and I think it's a great idea, we've just got stuff to sort out before we can get that far.
