Apple Final Cut Pro 5 - Manual (Page 1773)

422 Glossary
ganged The behavior of the playheads in the Viewer and Canvas when they’re locked
together, so that they move as one.
gaps Locations in a sequence where there is no media on any track. When output to
video, gaps in an edited sequence appear as black sections.
gear down To slow down a mouse operation and make it more precise by holding
down the Command key while dragging an item or control. This can be helpful when
dragging clips if, for example, the Timeline is zoomed out so that clips look small. It’s
also useful to gear down if you want to make very small changes to an edit point, a
keyframe parameter, or a volume level.
generators Clips that are synthesized by Final Cut Pro. Generators can be used as
different kinds of backgrounds, titles, and elements for visual design.
handles Extra footage beyond a clip’s In and Out points. Handles are useful if you want
to add a few more frames to account for dissolves or additional trimming.
HDCAM A high definition digital videotape recorder format that records an 8-bit,
7.1:1 DCT compressed component video signal with 3:1:1 color sampling. Recorded
using 1/2 inch tape. Supports four tracks of audio.
HDV An MPEG-2–based high definition video format that records on a DV cassette
tape. HDV supports both 720p and 1080i, and uses interframe (or long-GOP MPEG-2)
compression. Depending on the format, HDV has a data rate of 19 Mbps or 25 Mbps.
head clip The clip that begins a sequence.
headroom The available range in decibels (dB) that falls in between the reference level
that is used to denote the average loudness of a mix and 0 dBFS. If you mix your
project with the reference level set to –12 dBFS, you have 12 dB of headroom available
before the signal is clipped. If the audio in a sequence has a wide dynamic range, you
set the reference level low enough to create enough headroom so that no part of the
signal goes above 0 dBFS.
Hi-8 An analog videotape format. Introduced as a higher quality version of 8 mm.
Histogram A video scope in Final Cut Pro that displays the relative strength of all luma
values in a video frame, from black to super-white. It is useful for comparing two clips
in order to match their brightness values more closely.
hue An attribute of color perception, also known as color phase. Red, blue, yellow, and
green are all different hues.
