XVID file format
| Extension | .xvid |
| Category | video |
| Description | .xvid (Xvid Video Codec) The .xvid format is not a standalone file format, but rather a codec, which stands for 'compressor-decompressor.' Xvid is an open-source video codec library that follows the MPEG video coding standard, specifically MPEG-Part Advanced Simple Profile (ASP). It provides a high compression rate and can be used to compress video files to reduce their size while retaining high visual quality. Xvid-compressed files can be saved in various container formats such as AVI or MKV. It is a popular format for distributing movies and TV shows over the internet due to its efficiency and compatibility with numerous media players and devices.
