AVI MP4 Converter is a feature-rich software application designed to turn a wide array of video files into 3GP, AVI, MP4, WMV, VOB and other extensions, prepare them for playback on Andoid, iPad, iPod, iPod touch and Windows Phone, as well as to extract the audio stream and save it to AAC, AC3, MP3 and other sound formats. It can also extract frames and save them to popular photo file types like BMP, JPG, TGA and TIFF.

Installing the app takes minimal time and effort. When it comes to the interface, AVI MP4 Converter keeps it simple and organized, allowing users to add files to the task list with the help of the file browser, folder view or drag-and-drop support. It is also possible to add movies from DVD discs.

The task list shows the name, format, duration, width, height, frame rate, bit rate, frequency and channel mode for each clip.

Apart from specifying the output destination and format, it is possible to modify audio and video parameters when it comes to the codec, quality, size, frame rate, aspect ratio, width and height, cropping, rotation, flipping, bit rate, channel mode, and so on.

What's more, you can convert just a part of the videos by specifying the start time, preserve the original folder structure, ask the tool to automatically open the target directory on task completion, merge all clips instead of creating a separate file for each one, and more. During conversion it is possible to set the PC to automatically power off afterward, as well as to change the job priority level.

The tool does not put a strain on PC performance, since it runs on low CPU and RAM. No error dialogs were shown in our testing, and the app did not hang or crash. It delivers media files with very good image and sound quality. However, it takes a very long time to complete conversion, an aspect that does not justify the price of the full package.
