MKV (Matroska Video Container) is best for archiving high-quality video with multiple audio tracks, subtitle streams, and chapter markers in one file. AVI (Audio Video Interleave) is best for storing uncompressed or lightly compressed video for editing on windows-based workflows. Key tradeoff: MKV's advantage is the most flexible container: unlimited audio tracks, subtitle formats (srt, ass, pgs), chapter markers, and attachment files in a single open-standard file, while AVI's advantage is extremely simple container structure that every windows media tool has supported since 1992.
