Abdio PSP Video Converter is a utility that provides you with the function of converting video files into the Mp4 format, which is compatible with the PSP player.
The application supports lots of input formats, including WMA, AVI, ASF, WMV, AVS, FLV, 3GP and many more. You can customize your conversions by adjusting output parameters such as video and audio bit rate, audio sample rate, audio channel, audio volume and audio encoder. The application's graphic interface is intuitive and very easy to use. To convert your files, you just need to add them into the program's main window, click on the 'Options' menu to adjust the output parameters and then click on the 'Start' button to start the process. You can set an output folder to save your files to. With this program, you will be able to convert many different video file types into the Mp4 format at once. The application lacks a media player to play the supported formats, but it's still a good program.
You can use this program for free for a period of 6 days. Also, the trial version only supports AVI, WMV, WMA and ASF as input formats.
