Why convert WebM to FLV?
WebM is a royalty-free, open video format developed by Google specifically for the web. It uses VP8 or VP9 codecs to deliver high-quality video at small file sizes, making it ideal for HTML5 video playback. 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. Converting from WebM to FLV is useful when you need converting legacy flash content or want to take advantage of small file sizes.
