CBS and For-A worked with Evertz to develop DreamCatcher. This is what DreamCatcher can do according to David Pierce, The Verge:
[…] lets the production crew immediately tap into the 4K footage to get larger, more detailed replays than a 1080p camera offers. With four times the pixels comes much-improved clarity, and a 1920 x 1080 cross-section of the image is going to be far sharper than the blurry replays we’re used to seeing.
Imagine the Olympics, the World Cup, the NBA, the MLB, etc. using 4K video analysis technology. 4K is sooner than later.
