Apple’s new iPhone 4 has hit the market to much fanfare as expected, and one of the most talked about features is video calling. While Apple is touting its new FaceTime application that will only work between iPhone 4 users, it is only a matter of time before other apps make their way into the market to provide greater flexibility for video calling between any mobile devices. For example, one of my previous posts shows a demonstration of what high definition Movi mobile video would look like on an iPhone, and other consumer grade products like Skype already have audio applications for smartphones and are working to deliver video.

Given Cisco’s recent estimation that video will be a significant part of what they believe will be a $34 billion collaboration business, it is reasonable to expect a proliferation of smartphone video applications in the near future. But what will the key features of smartphone video applications be? I think high definition resolution will be critical on the small screens to help ensure the best visual experience. Also, basing the video applications on open standards will be key for ensuring that callers can reach anyone at anytime, regardless of vender or hardware – enabling true video collaboration.

What do you think are some critical features for smartphone video applications?
