Even though HTML5 is gradually replacing FLV (Flash Video) as the standard for streaming media over the Internet, FLV is still used by over one billion people worldwide for embedded video and on social networks such as Facebook or YouTube. However, to be played on a PC or Mac, FLV requires that you install additional codecs, and many mobile devices don't support this format at all. So if you want to watch a video you've downloaded from the Web on your computer or mobile device, make sure to convert the video to a more universal format such as MP4 or MPEG-4. Movavi Video Converter will help you get this done in no time.
