How to Use Movavi’s MP4-to-FLV Converter

The MP4 video file format is a part of the MPEG-4 standard. MP4 files can contain video and audio streams, subtitles, and metadata. The format is supported on both Windows and Mac as well as many other devices – smartphones, tablets, HDTVs, video game consoles, and more. FLV (Flash Video) is, along with HTML5, the standard for streaming media over the internet and is used by over a billion people worldwide for embedded video and videos posted on social networks like Facebook or YouTube. Although MP4 is widely used, some sites still recommend you upload videos in FLV format, so in those cases, you would have to convert MP4 to FLV. You can easily complete either of these tasks with Movavi Video Converter, so read this guide and learn how to transform MP4 to FLV while retaining the high quality of the original video.
