Aiseesoft FLV Video Converter supports converting a huge range of media formats, including FLV. The software has a nice multi-language skinnable interface, with a layout similar to those of other converters. Therefore, if you have used this type of application before, you will probably find your way through this one easily.
Perhaps, some of its features may not be obvious at first sight, but I can guarantee that you will be using all of them with no difficulty.
The program supports batch conversion, so several files can be added, individually or as complete folders. At this point, the files can be previewed and while doing so, snapshots of your favorite scenes can be taken as well.
Several authoring actions can be performed on the clips before actually converting them. If you just need to extract a segment from the whole file, you can easily trim it by marking the beginning and ending times. Similarly, you can crop the frame so that only the desired screen region is converted. Additionally, you can adjust such picture parameters as brightness, saturation, contrast and hue. In order to identify your files, you can use watermarks, too. Finally, you can merge various clips into a longer video. Unfortunately, the program does not support adding external subtitles to your video, a feature that is already available in many other converters.
Probably the main advantage of this program (its name may be misleading in this respect) is the enormous array of output formats available. Thus, many conversion presets are classified according to different criteria, such as compatible devices and supporting applications. However, if none of them satisfies your exact needs, you can always create new profiles and save them for other occasions. Fortunately, not all the files on the list need to be converted to the same output profile, because individual conversion parameters can be set individually.
In general, Aiseesoft FLV Video Converter supports practically every existing format. The availability of predefined conversion profiles is a guarantee that no compatibility issues will appear when you try to play the resulting files on your portable device. You may also be very pleased with the features allowing you to perform simple editing actions on your videos. The support of modern hardware definitely shortens the conversion time and increases the quality of the results.
