4.2

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.
Batch In Compressor, one or more jobs to be processed. All jobs
contained within the batch (shown in the batch area of
Compressor window) are submitted collectively when you begin
the transcoding process.
Bit rate The number of bits per second in the transmission of a
digital video or audio signal. The higher you set the bit rate, the
better the quality of the output file. However, higher bit rates
require larger file sizes.
CAF (Core Audio Format) Apple’s Core Audio Format is a
flexible file format for storing and manipulating digital audio data.
CAF provides high performance and flexibility, and is scalable to
future ultra high-resolution audio recording, editing, and playback.
Closed captions Onscreen text corresponding to the audio of a
video program. Originally developed for hearing-impaired viewers,
closed captioning (also known as line 21 text) is also frequently
used on televisions in loud environments (such as restaurants and
bars) or in locations where playing the audio might be considered
rude or inappropriate (such as hospital waiting rooms).
Codec Short for COmpression/DECompression. A software
component used to translate video or audio from its current form
to a different, digitally compressed form. A codec encodes a data
stream or signal for transmission, storage or encryption, or
decodes it for playback or editing. A similar term, encoder, is
used to describe hardware that performs the same activity.
