This tool can convert almost any video file to MP4 format, specifically for playback on iPod and PSP devices.
To install Convert 2 Video MP4, simply execute the install script, which will create a directory called .convert_2_mp4 on your home directory. The script, icon files and the *.desktop file will be kept there, while the *.desktop file will be located in the standard KDE konqueror service menu directory at $HOME/.kde/share/apps/konqueror/servicemenus. To use the konqueror service menu, right-click on a video file and select Convert 2 MP4. The resulting converted file will have the original name, codec, format, and an .mp4 extension.
You can select and convert multiple files at a time, but ensure they are of the same format, whether 16:9, 4:3, or 2.35:1. Note that Xvid is considerably faster than h264, and the convert service menu selections are classified according to the following format: "Codec-Resolution-Screen format-Video bitrate". For example, "Xvid-iPod-4:3-300k.Bitrate" denotes Xvid as the codec, "iPod" as the resolution (PSP and TV are available too), "4:3" as the screen format (16:9 and 2.35:1 are the alternatives), and "300k" as the video bitrate (500k and 800k apply to TVs).
Overall, Convert 2 Video MP4 is an excellent tool that offers an array of features to convert almost any video file into MP4 format to play effortlessly on mobile devices like iPod and PSP.
