The following diagram illustrates how the standard Compressor transcoding process
works. The largest transcoding component is a batch. The batch represents all the
components needed to transcode your current media. It must contain one or more jobs.
A job consists of at least one source media file with one or more targets, each with a
setting and a destination associated with it. After the transcoding process, the resulting
file is known as the output media file. One output media file is created for each setting
assigned to a source media file.
In the illustration below, the batch contains two source media files, each of which is a
job containing two targets (sets of a setting and destination). The total number of output
files created by transcoding this batch will be four: Job 1 will create two output media
files, as will Job 2.

• Codec: Short for COmpression/DECompression. A mathematical model for reducing the
data of a source media file.
• File Format: The output format you use to transcode your source media file.
• Group: Contains designated settings placed into a folder in the Settings tab. Groups
help you organize your settings and can simplify the job creation process.
• Transcoding: The process of converting files from their original format into output files
ready for distribution in another format. Closely related terms include compression,
which specifically refers to data reduction, and encoding, a term that is essentially
synonymous with transcoding, but does not emphasize the conversion aspect.
• Source media file: The transcoding process always starts with a source media file, which
is the file intended for transcoding in its original form. Source media files are always
one of the following.
• Movies: Containing video, audio, and other data (such as markers)
