waveform monitor A video scope in Final Cut Pro that displays the relative levels of

luma and chroma in the clip currently being examined. Spikes and dips in the displayed

waveforms correspond to light or dark areas in your picture. See also chroma, luma.

white-balance To make adjustments to a video signal being recorded in order to

reproduce white as true white. For example, if the white in a shot is too yellow because of

incandescent lighting, white-balancing adds enough blue to make the white appear neutral.

widescreen Any movie presentation that has an aspect ratio wider than 4:3. In movie

theaters, 1.85 is considered standard and 2.40 is considered widescreen. For video, 4:3 is

considered standard and 16:9 (which is almost the same aspect ratio as 1.85) is considered

widescreen. See also 4:3, 16:9.

wipe A common type of video transition. In a wipe, the screen splits, moving from one side

of the image to the other to gradually reveal the next shot. A wipe is more obvious (and

customizable) than a fade or cross dissolve. See also cross dissolve, fade.

XDCAM A Sony optical disc format for recording DVCAM and IMX video within MXF

container files. See also DVCAM, IMX, MXF.

XDCAM EX A member of the Sony XDCAM product family that uses MPEG-2 video

compression with 4:2:0 chroma sampling. In contrast to XDCAM HD, XDCAM EX supports

720p and records full HD resolution (either 1920 x 1080 or 1280 x 720). Its maximum bit

rate is 35 Mbps. Instead of optical discs, XDCAM EX camcorders use solid-state memory

cards known as SxS cards. See also chroma, HDV.

XDCAM HD422 A member of the Sony XDCAM product family featuring 4:2:2 chroma

sampling and a video bit rate of 50 Mbps. Like XDCAM EX, XDCAM HD422 uses

MPEG-2 video compression at full HD resolution (either 1920 x 1080 or 1280 x 720).
