A high definition video format (sometimes called sF, SF) designed to acquire, store, modify, and distribute content using interlaced equipment and media. A progressive frame is divided into two segments, odd lines in one, even lines in the other, with both fields representing the same instant in time. (These segments appear equivalent to interlaced fields, but there is no motion between the two.) This allows for a progressive picture to be processed through the same electronics used to handle interlaced video.canonglossaryus
An image sensor that gathers its data and processes each scan line one after another in sequence. Compare to Interlaced
All lines in a video frame are captured at the same moment, delivering higher vertical resolution and a more film-like look than interlaced video. This requires much higher resolution.
