What should the default call rate be set on a EX/C to achieve
Thanks in advance.
> What is the difference between setting that at 4Mbps vs 6Mbps or even 2.5Mbps for that matter.
This is more on user experience.
If you have more motion entire capturing video image (i.e. a lot of movement front of main camera) instead of quite still image, then require higher bandwidth for full picture update.
Also higher bandwidth connection allow to settle down the full picture (again this is very depend of expectation and experience as talking about few seconds difference).
