This process means the removal of one of the colors to bring in another image that serves as a background for the topic.

Movies And MP3

Movies and MP3 files are already compressed with near maximum capacity. Repacking them would just create larger files and increase decompression time. Ripped movies are still packaged due to the large file size, but compression is disallowed and the RAR format is used only as a container. Because of this, modern playback software can easily play a release directly from the packaged files, and even stream it as the release is downloaded (if the network is fast enough).

MP3 and music video releases are an exception in that they are not packaged into a single archive like almost all other sections. These releases have content that is not further compressible without loss of quality, but also have small enough files that they can be transferred reliably without breaking them up. Since these releases rarely have large numbers of files, leaving them unpackaged is more convenient and allows for easier scripting. For example, scripts can read ID3 information from MP3s and sort releases based on those contents.
