AVI

Avi file format

AVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992, widely used for storing video and audio data. It is supported by many media players like Windows Media Player, VLC, and editing tools such as Adobe Premiere and VirtualDub. The format uses a chunk-based structure to store audio and video streams, allowing for synchronization, and supports multiple codecs, though it lacks advanced features like metadata and streaming capabilities found in modern formats.

MKV

Matroska Video file format

MKV (Matroska Video File) is an open, flexible multimedia container format designed to store video, audio, subtitles, and metadata in a single file. It is widely supported by media players like VLC, MPC-HC, and tools such as MKVToolNix for editing and muxing. The format uses EBML (Extensible Binary Meta Language) for its structure, enabling advanced features like chapter support, multiple audio tracks, and seamless streaming capabilities.
