About FLV Compression
FLV (Flash Video) is a legacy format from the Flash era. While Flash is deprecated, many archives and content libraries still contain FLV files taking up significant storage.
CocoConvert's FLV compressor re-encodes the video stream with efficient H.264 encoding within the FLV container. For most users, converting FLV to MP4 is recommended for modern compatibility — CocoConvert offers that conversion too.
FLV files from screen recordings and early web video are often poorly compressed, making them excellent candidates for recompression with modern codecs.
Typical reduction is 50-75%, with older/poorly-encoded FLV files seeing even greater savings.
