batch Compressor uses a batch to contain one or more source media files that you want to
convert, or transcode, to another format. Each source media file creates its own job. This
means that a batch can contain multiple jobs, with each job based on its own source media
file. Each job also has at least one setting that defines the format of the transcoded file.
See also source media files.
batch share
A feature in Final Cut Pro that allows you to share multiple projects, clips, or
ranges in a single export.
Bezier curve A parametric curve used to create smooth movement for keyframes and
animated objects and to create precise, detailed mask shapes. Bezier curves contain two
kinds of points: smooth points with handles that can be manipulated to curve the adjacent
line segment, and corner points that have no handles and therefore have straight (or linear)
adjacent line segments.
bit rate The number of bits that are processed or transmitted per unit of time. The higher
the bit rate, the better the quality. However, higher bit rates require larger file sizes.
Blade tool The editing tool that allows you to cut clips in the timeline. You can select the
Blade tool by pressing the B key.
blue laser media Blu-ray burners and players use a blue laser when working with Blu-ray
media. The blue laser has a shorter wavelength than the red laser used for DVDs, making it
possible to store more data on a disc. See also red laser media.
blue or green screening See chroma key.
broadcast-safe Broadcast facilities have limits on the maximum values of luma and
chroma that are allowable for broadcast. If a video exceeds these limits, distortion can
appear, resulting in unacceptable transmission quality. You can use the Final Cut Pro video
scopes to make sure that the luma and chroma levels you set stay within acceptable limits.
See also chroma, luma.
B-roll A term used to describe alternative footage shot to intercut with the primary shots
used in a program. B-roll is frequently used for cutaway shots. See also cutaway shot.

filmstrips or in a list. See also sidebar.
