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. See

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 hues.
image sequence A movie exported as a series of numbered image files, stored in a folder.
Each image file contains one frame of video. Image sequences are typically used for
exchanging files among film compositing workstations. Common image sequence file
formats include Targa, TIFF, IFF, DPX, and OpenEXR.
importing The process of bringing files of various types into a project in Final Cut Pro.
Imported files can be created in another application, captured from another device, or
brought in from another Final Cut Pro project.
IMX A standard definition, all-I-frame MPEG-2 format stored on tape, optical disc, or disk
drive. Some IMX decks can play back and convert formats such as Digital Betacam, Betacam
SX, and Betacam SP to IMX. The data rate of IMX can be set to 30, 40, or 50 Mbps.
incoming clip The clip to which a transition segues. For example, if Clip A dissolves to
Clip B, Clip B is the incoming clip.
ingesting The process of bringing media into a video system for editing. Ingesting includes
capturing tape-based media, transferring file-based media, and importing media files
stored on disk. See also

In point The edit point that specifies the first frame of a clip to be edited into a sequence.
insert edit An edit in which a clip item is added to a track in the Timeline at a specified
point, moving clips (or parts of clips) after that point to the right. An insert edit does not
replace existing material.
interlaced video A scanning method that divides a video frame into two fields, each
consisting of alternating odd and even lines that are scanned at different times.
