FLV and MP4 are two popular container formats that're used for distributing videos online and offline. But there are big difference between FLV and MP4. As FLV is developed by Adobe and mainly used for streaming flash video by sites like YouTube, Hulu, Facebook and other video-hosting providers, in most of time, you will have to install a flash plugin or Adobe FLV player to handle it.

In comparison, MP4, which can hold mpeg-4 or h.264 encoded video, is the most powerful standard on this planet at current. Almost all typical desktop media players, phones, tablets, e-readers, and other devices support the playback of MP4.

Suppose if you've downloaded some favorite video clips from YouTube site, then you realize that the files' extension is .flv and no media player on your computer supports, let alone your portable device. When this happens you usually have several ways to deal with it. One of the most efficient ways is to convert the FLV to a MP4 format on Mac or Windows computer that players and devices actually do support.

There are many apps available for converting flash flv files to MP4 format, but it is extremely important that you use the right tool for doing this.
