Why convert FLV to AVI?

FLV was the dominant format for web video during the Adobe Flash era. While Flash is deprecated, FLV files still exist in many legacy systems and require conversion to modern formats for playback. AVI is a legacy Microsoft container format that preserves high video quality with minimal compression. It remains popular for archival and Windows-based workflows where compatibility with older software matters. Converting from FLV to AVI is useful when you need windows-based playback and editing or want to take advantage of high video quality.
