4K resolution is a video format of about 4,000 horizontal pixels, delivered as 3840x2160 UHD for consumer screens or 4096x2160 DCI 4K for cinema.
Aspect ratio in video is the proportional relationship between frame width and height, such as 16:9 or 2.39:1, which shapes composition and delivery.
Frame rate is the number of distinct images a video system captures or displays per second, shaping motion smoothness, motion blur and delivery standards.
Interlaced video is a scanning method that splits each frame into two fields of alternating lines, doubling motion sampling without doubling bandwidth.
Motion blur in video is the smearing of moving subjects within each frame, set by shutter speed and shutter angle, that makes motion look smooth.
Progressive scan is a video method that captures and displays every line of each frame in sequence, producing complete frames without interlacing artifacts.
Resolution in video is the number of pixels in each frame, stated as width by height, which sets the maximum detail a recording or display can…
Shutter angle expresses video exposure time per frame as degrees of a rotary shutter, with 180 degrees giving half the frame interval.
