LetsFun FLV Converter is a program that you can use to encode video clips from and to FLV, MPG, AVI, WMV, MP4, MOV and 3GP. But it can also extract the audio stream and save it to MP3, AMR, WMA and WAV.

The tool is wrapped in a user-friendly interface where you can add videos to the file list by using either the file browser, tree view or "drag and drop" functionality. Handling multiple items at the same time is possible.

In the file queue you can find out the source location and type of each item. If you are satisfied with the default settings, then you can immediately start the encoding operation after establishing the output profile and directory.

Experienced users can change the audio and video bit rate, along with the screen size. Plus, you can remove an item from the list. In the "Options" area you can disable the sound reminder and trim videos by marking the start and end time values.

The video processing program supports keyboard shortcuts and includes a help file. It converts a videos in reasonable time while using a low-to-moderate amount of CPU and system memory. We have not come across any technical difficulties throughout our testing; LetsFun FLV Converter did not freeze, crash or pop up errors.

On the other hand, you cannot configure additional audio and video settings (e.g. volume level, channel mode, aspect ratio), specify the thread priority or set LetsFun FLV Converter to automatically power off the computer after conversion. Also, the app does not do a very good job when it comes to preserving a good image and sound quality.
