How to Convert MP4 to FLV with Zero Quality Loss

If you’ve ever been to a computer developer’s forum, you probably noticed a lot of controversy surrounding the Adobe Flash Player and anything associated with it. In fact, simply mentioning the word “Flash” is often enough to send the most energetic of developers into a frothing rage. So, what’s the big deal with Flash and what does FLV have to do with it anyway?

FLV file format is short for FLash Video. It began life in 2003 with the release of Adobe Flash Player 6 and was originally intended for high-quality interactive real-time streams. FLV was meant to become the synonym for a fully immersive way to deliver video content to everyone with a browser Flash plugin. While it didn’t quite succeed in becoming as relevant as its creators hoped, FLV media files can still be used to exchange data with Adobe Flash Media Servers.

The obvious problem with this approach is that it opens the user to a number of security and privacy issues, which is what angers the aforementioned developers the most. So, while they’re fighting for the noble cause of making the cyberspace a safer space, let’s take a look at how to best convert MP4 to FLV.
