The following video was shot from the pressbox of a high school stadium. The video has been compressed and resized to the same dimensions that you would likely observe in Game Data Live. The original video was shot in 720p HD (1280 x 720 resolution).
This video was shot using Game Data Live running on an iPhone 6 Plus and a 2.2 X telephoto lens from IOGrapher. An iPhone 6 Plus has an 8 megapixel imager with focus pixels. This video was shot without a tripod.
You can get great sideline video without using a camcorder.
This video will look even better on an iPad with a Retina display than it does in this browser.
