Aiseesoft PSP Video Converter for Mac is a video conversion tool that can be used to convert your video files so that you can play them on your PSP. This converter supports the following output formats: MPEG-4, DivX, XviD, H.264, WMV, WebM and AVI. Some of those formats are supported both by the PSP and the Playstation 3. The app comes with conversion profiles for Sony devices and a few others. A few different models of the PSP are included, such as the PSP Go and the PSP 3000. If you look into "All Profiles", you will find a profile for the Zune and one for the Xbox 360. The developers probably forgot to delete those.
The graphical user interface is quite simple, and before you load your video files for conversion, you will see on-screen instructions on how the application is used. The main window has a video player, and you can access a video editor from the top toolbar. This editor lets you trim and crop your videos, adjust their brightness, contrast and saturation and even add watermarks.
In conclusion, this converter is a good one. It works well and it is easy to use. It also has good format support and the basic feature set, that you can find in commercial converters these days.
