Convert FLV to AVI for compatibility with older video editing software or Windows systems.
FLV was the dominant web video format during the Flash era. While Flash is now deprecated, FLV files still exist in many archives and legacy systems.
AVI is a classic multimedia container format introduced by Microsoft in 1992. While considered legacy, it remains widely used for compatibility with older systems and simple video storage.
Both are legacy formats. AVI has broader editing software support. Consider MP4 for a modern alternative.
