WinX Free PSP Video converter converts files from most popular video formats into the two formats that the Playstation Portable (PSP) can play natively (AVC and MPEG-4).
AVC is not a very popular format, but MPEG-4, also known as MP4, is played by most devices. This free converter offers three conversion profiles for AVC and three for MP4.
There is a normal, excellent, and best quality profile for each format. Both audio and video quality change with each profile. Sadly, there is no way to customize the profiles. But you can change the settings manually. You can change the bitrate both for audio and video, the video resolution, and frame rate.
All in all, WinX Free PSP Video Converter does a good job converting files to AVC and MP4.
