MPEG is a relatively popular video format, and at the same time it is also a video codec. Files contained in MPEG extension are easy to stream and download, and they can be played on many different multi-media players and programs like Windows Media Player, VLC, QuickTime, iTunes, etc. However, for some specific purpose, we might want to convert MPEG to FLV. Here let’s take a deep look at different ways to convert MPEG to FLV.

Part 1: Why Is It Necessary to Convert MPEG to FLV?

Before we move to explain why it is necessary to convert MPEG to FLV, let’s figure out what MPEG and FLV is first.

What Is MPEG?
Standing for Moving Picture Experts Group, MPEG video files are compressed using either MPEG-1 or MPEG-2 compression. As we mentioned in the very beginning, MPEG is a video codec as well used to display video and DVD files and to compress data to form small bits that could be transmitted easily. MPEG has high compression rate, and it could be handled through software or hardware. MPEG could be divided into MPEG-1, MPEG-2, MPEG-4, MPEG-7, and MPEG-21.

What Is FLV?
Standing for Flash Video, FLV is another file format used by Adobe Flash Player or Adobe Air to store and deliver audio and video streams over the Internet. FLV can be used as an embedded video on the Internet including YouTube, Hulu and so on. If your computer has installed Adobe Flash Player, then FLV will be viewable on most operating systems. Besides, the FLV video is relatively smaller than MPEG video format.

Why Do We Convert MPEG to FLV?
Let’s say, you have some MPEG videos at hand and you want to share the MPEG videos on some video websites, such as YouTube. Such being the case, you have to convert MPEG to FLV in order to fit properly on the website. Besides, due to the smaller size of FLV format, in most cases, FLV can be uploaded to website more quickly and could be watched more smoothly online. Therefore, it is quite popular and necessary to convert MPEG to FLV nowadays.
