Ultra AVI Converter is used for converting video files into popular video file formats, such as MP4, DivX, MPEG 1 or 2, AVI, ASF, and many others. It supports input of formats like Xvid, DivX, and AVI. The application has a simple interface that is easy to navigate and use. It also supports batch conversion, which allows users to convert several files all at the same time in order to save time.
On the main interface, users can import files to the application by clicking on the plus sign button on the upper portion of the window. All files imported to the application appear as a list on the main window. Information, such as the source file, resolution, start time, end time, and status can be viewed as well. At the bottom part of the window, users can change the output folder, and output format. The right side of the window contains other settings, such as the output filename, video quality, video size, audio quality, audio volume, and letterbox. A small video player is located at the bottom right part of the window. This can be used to preview video files before or after they have been converted to other formats.
