Here’s a quick history of video resolution. For those of us that are old enough to remember standard definition tube TVs, the rough digital equivalent was 720 pixels by 480 pixels. When high definition (HD) was introduced, it started at 1280 x 720 (also called 720p) and quickly moved to 1920 x 1080 (also called 1080p). 1080p has been the standard for the past eight to 10 years, roughly. Within the past couple years, 4K (3840 x 2160) TVs, displays, and camcorders have started to flood the consumer marketplace. Looking to the future, resolution will just continue to increase...4K is not the ceiling. 5K (5120 x 2880) and 8K (7680 x 4320) already exist.
