Question: what is the difference between an hd camera and a 4k camera?
Answer: 4k, also called Ultra High Definition (UHD), refers to the almost 4,000 horizontal pixels it has, whereas Full HD 1080p refers to 1080 vertical pixels it contains. 4k generally translates as highly detailed, crisp, and cleaner looking video than 1080p, especially when played on a 4k monitor.
