english: You see, most cameras record images one row at a time, and so if an object moves during the recording of a single image, there's a slight time delay between each row, and this causes slight artifacts that get coded into each frame of a video.
non_english: Vidite, većina fotoaparata snima slike jedan po jedan red, tako da ako se predmet pomeri tokom snimanja jedne slike, postoji kratko kašnjenje između svakog reda i zbog ovoga ostaju blagi tragovi koji se kodiraju u svaki frejm snimka.
