There are currently 6 names in this directory beginning with the letter U.
UHD
UHD or Ultra High Definition is also sometimes called ‘4K’ by people although the formats are slightly different – 4K has a screen aspect ratio (format) more suitable to cinema screens, whereas UHD is 16:9 ratio which is the same as most home TV screens. UHD is 4x the quality of HD (1080p) TV. UHD is also known as 2160p (3840 x 2160 pixels).
Ultrasonic cleaner
An Ultrasonic Cleaner is equipment used by film and video production companies to clean film by using sound waves, without application of any pressure, solvents or abrasive techniques. (Lab)
Unbalanced frame rates
Unbalanced Frame Rates will produce errors in production, for example if shooting at 22 frames per second. Video companies often use Ramping when choosing to shoot slow motion, however this should not be confused with Unbalanced Frame Rates (Camera Crew & editing)
Undercranking
Undercranking is filming using a low frame rate, which when played back, produces a fast-motion action.
Underscore
The musical composition that provides emotional or atmospheric background to the primary dialog or narration onscreen.
Upscaling
Upscaling: Upscaling is a process that mathematically matches the pixel count of the output of a standard or non-hi-def signal (such as standard DVD) to the physical pixel count on an HDTV, which is typically 1280x720 (720p) or 1920x1080 (1080i or 1080p).
