About AVI Format
AVI (Audio Video Interleave) is a multimedia container developed by Microsoft. It supports multiple audio and video codecs but lacks native support for modern features like variable bitrate and subtitles. Still widely used for compatibility.
About FLV Format
FLV (Flash Video) was the dominant web video format during the Flash era. While largely replaced by MP4 and WebM for web delivery, FLV files are still encountered in legacy content and some streaming servers.
