This program is more than its name implies. Besides helping you convert FLV files to various video and audio formats, the application is also capable of extracting soundtracks from multiple types of media files, trimming clips, and playing movies once the conversion process is complete.
You can import one video file at a time, trim it if necessary, and choose the preferred output quality level. After you choose the proper output format and destination folder, click the "Convert Video" and wait for the results.
The application preserves the quality of the original videos and uses minimum CPU resources while generating the media files.
Still, this program isn't the best there is. The application supports a relatively small amount of output formats. It also displays annoying ads and doesn't offer you support for batch conversion. The only way to get rid of the two aforementioned issues is to upgrade the utility to its Plus version.
In my opinion, you should look for a different FLV converter. There are plenty of other video converters that work with more file formats, give you access to multiple editing options, and cost as much as this program or even less.
