OJOsoft DVD to MP4 Converter is a piece of software that allows you to encode DVD videos into MP4 files. But it can also prepare items for iPhone, iPod, Zune and PSP, among other devices.

The interface of the tool is based on a standard window where you can import a DVD movie by selecting its source drive or by using either the file browser or folder view (the "drag and drop" method is unsupported). Unfortunately, you cannot process multiple DVD clips in a single session.

In the file list you can check out the title and duration of the movie. Once the output profile and destination are established, you can start the conversion procedure with the default settings.

Advanced users can fiddle with the audio and video settings in regard to the frame size, aspect ratio, resize method, compression mode, bit rate, frame rate, frequency, number of channels, volume level, deinterlacing and sync mode.

These options can be saved to a new profile or restored to default. Furthermore, you can select the audio language and subtitle track, as well as split clips by chapters. OJOsoft DVD to MP4 Converter offers to open the output folder when the task is done.

The video processing tool requires a low-to-moderate amount of system resources to finish a task quickly. It has a good response time, includes a help file and outputs videos with a good image and sound quality. No errors have popped up during our tests and OJOsoft DVD to MP4 Converter did not freeze or crash.

On the downside, you cannot preview clips in a built-in media player, select the number of CPU cores in use or set OJOsoft DVD to MP4 Converter to automatically power off the computer after conversion.
