audition In Final Cut Pro you can organize related clips into sets, called auditions, from which
you can choose one clip to use. You can create an audition composed of different clips to try out
multiple takes, or you can create an audition composed of multiple versions of the same clip to
preview different effects. Auditions appear in the Event Browser and Timeline as clips with an
Audition icon in the upper-left corner.
automatic audio sync The “Use audio for synchronization” option in the multicam clip creation
process makes precision sync adjustments using audio waveforms in the angles of a multicam
clip. This is the same audio sync technology that you can use to automatically analyze and sync
clips together into a compound clip.
AVCHD A high-definition (HD) video format that uses Advanced Video Coding (AVC)
compression (also known as MPEG-4 part 10 or H.264). Many Blu-ray players can play red laser
discs with AVCHD format content, making this a common way to distribute short HD video
projects using a standard red laser disc.
Background Tasks window The Background Tasks window shows the progress of importing,
transcoding, analysis, rendering, sharing, and other tasks.
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.
bit rate The number of bits per second that makes up a digital video or audio asset. 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 color has a shorter wavelength, making it possible to store more data on a disc when
compared to red lasers.
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.
B-roll A term used to describe alternate footage shot to intercut with the primary shots used in
a program. B-roll is frequently used for cutaway shots.
BWF (Broadcast Wave Format) An extension of the WAV file format that includes additional
metadata such as timecode and production information.
CAF (Core Audio Format) Apple’s Core Audio Format (CAF) is a flexible file format for storing
and manipulating digital audio data. It is fully supported by Core Audio APIs on Mac OS X v10.4
and later and on Mac OS X v10.3 with QuickTime 7 or later. CAF provides high performance and
flexibility, and is scalable to future ultra high-resolution audio recording, editing, and playback.
chroma The color information contained in a video signal, consisting of hue, which represents
the color itself, and saturation, which represents the intensity of the color.
