Aiseesoft MP4 Converter Suite is intended to help you work with MP4 video files. As its name suggests, it is essentially a suite composed of two applications: Aiseesoft DVD to MP4 Converter and Aiseesoft MP4 Video Converter.
The suite has an easy-to-use interface that works as a sort of launch pad to start the component applications. The two converters, in turn, also have intuitive interfaces, which you will not have any difficulty to use if you are already familiar with this type of software.
Aiseesoft DVD to MP4 Converter is to rip DVD contents to MP4. It supports various DVD sources, such as discs, folders and IFO files. As a limitation, it does not allow converting clips from ISO image files. The output profiles are grouped according to the supporting devices.
Aiseesoft MP4 Video Converter can convert standard video files from a format to another, and it supports a wide range of both input and output formats. Again, you can avoid compatibility issues by choosing the name of the intended device.
Both converters allow performing basic authoring operations. Thus, you can use them to crop the visible region of the frame, extract a segment from a file or add effects to your videos.
In general, Aiseesoft MP4 Converter Suite provides a practical way to organize two tools that complement each other well for managing MP4 video. However, I see no reason to use two separate applications for this purpose. I have actually seen all the features provided by this suite, successfully packed into a single application instead. In fact, it seems that Aiseesoft MP4 Converter Suite is just a marketing strategy to sell you two applications as a package. Therefore, you should decide whether you would save your money or spend an extra amount on something you do not need.
