Yes, the aim is as said, to make it a watchable camera. So when you're not batting and just watching the game go by you can have it on broadcast and it'll look great.
It's also a nice addition for us to use in the demo mode that loads up when you don't touch the game, so it makes it look pretty.
I'm not quite sure what you're asking in terms of what the camera does. But the Broadcast Camera was designed and built by watching hours and hours of actual TV footage and then applying it to the game, so if it's done in normal TV broadcast then you can assume it is happening in our Broadcast Camera.It's our opinion, for local multiplayer, that it will be best to use the 'Far (Bowling)' camera. We have that as the default option with options to invert the batting controls if needed to suit the camera positioning as well.
The 'Far (Bowling)' camera will provide you with the down the pitch view that you want from Broadcast, but won't have that camera pan that is giving you motion sickness.
As said, the Broadcast camera is mainly for you to watch the game with, not really to play it from. Any other camera is designed for gameplay purposes, the Broadcast is mainly for hands off purposes.
