Rival FLV Encoder is one of the most powerful applications of its kind, as it’s being able to convert almost any video file out there and encode it in the FLV format in a matter of minutes.

Installing the software solution is absolutely easy because the developer hasn’t included complicated steps in the setup process.

The first run will bring you a very clean and pleasant interface, which means it should be easy to use too. And it is, as all functions are nicely grouped into the main window for instant access.

Picking a file to work with, as well as the destination video file, can be done from the left side of the main window, while the right one has been reserved exclusively for tweaking settings, such as video size, framerate and audio settings.

After a few tests, we must admit that we’re really impressed with Riva FLV Encoder, as the whole conversion and encoding thing goes incredibly fast without stressing up our testing machine.

Truth is, the application sometimes gets unresponsive when working with larger files, but that’s probably a compatibility issue with Windows 7.

All things considered, there’s no chance not to be satisfied with Riva FLC Encoder if you really need such a tool. And probably the most important thing is that it’s free, so you can enjoy all its great features without paying a dime.
