Description.xvid (Xvid Video Codec) The .xvid format is not a file format per se, but rather a codec, which stands for 'compressor-decompressor.' Xvid is an open-source video codec library following the MPEG- video coding standard, particularly MPEG- Part Advanced Simple Profile (ASP). It offers a high compression rate and can be used to compress video files to make them smaller while maintaining high visual quality. Xvid compressed files can be stored in different container formats like AVI or MKV. It's a popular format for the distribution of movies and TV shows over the internet due to its efficiency and compatibility with many media players and devices.
Technical detailsThe Xvid codec, an open-source MPEG-4 video codec, is used within various multimedia containers like AVI, MKV, MP4. Key features include: - MPEG-4 Compliance: Fully adheres to MPEG-4 standards, ensuring compatibility with most MPEG-4 supportive devices. - High Compression Efficiency: Known for reducing file sizes while maintaining good video quality, beneficial for streaming and downloading over limited bandwidth. - Quality: Provides high-quality video at lower bit rates, optimizing file size and visual quality. - Open Source: Distributed under the GNU General Public License, allowing free use and modification. - Variable Bit Rate (VBR) Encoding: Supports VBR, adjusting bitrate dynamically for efficient quality and size. - Adaptive Compression Techniques: Utilizes advanced methods like B-frames, quarter-pixel motion compensation, lumi masking, and GMC for enhanced efficiency. - Cross-Platform Compatibility: Available on various operating systems, including Windows, macOS, and Linux. - Peer-to-Peer Network Popularity: Favored for sharing videos on P2P networks due to its balance of quality and file size. - Container Format Compatibility: Commonly used within container formats like AVI, with occasional use of the .xvid extension. - Advanced Features: Supports interlaced video, quantization matrices, and custom quantization. - Modern Limitations: Surpassed by newer codecs like H.264 and H.265 in terms of compression efficiency and device support. Xvid's significance lies in its early contributions to digital video compression and file sharing, though its prominence has waned with the emergence of newer codecs.
