Aiseesoft Flash Converter for Mac is a video conversion tool. It is marketed towards users who need to convert their video files into SWF or FLV videos. This was often done to help users upload videos to YouTube, but nowadays, YouTube supports quite a few video formats. There are some formats that YouTube doesn't yet support, and you can use this app to convert those files to one of the accepted formats. In fact, since this application doesn't really restrict the types of files that you can load and thanks to its great format support, you can use it as a general-purpose video converter. It can output files in the most popular video and audio formats, and it comes with conversion profiles for a number of devices. There are even HD profiles available.
Aiseesoft Flash Converter for Mac comes with a video editor and a video player. The former can trim, crop and add watermarks to your videos. It can also be used to adjust brightness, contrast and saturation. The latter lets you play your files before conversion and take JPEG snapshots.
The application works like a charm. It can produce nice-looking videos and it is quite fast. However, if you already have a converter that can output videos into SWF or FLV, you don't really need this one. It is identical to many other converters by Aiseesoft and it doesn't come with any specific feature for the conversion of Flash files.
