Kate's Video Toolkit is an easy-to-use, all-in-one solution for all your video needs. It can convert AVI, WMV, MPEG, MOV, MP4, 3GP and ASF files into a variety of output formats, including AVI, WMV, MPEG, MOV (Quick Time), VCD, and DVD.
If you are one of those who love to play around with sounds or edit videos, then this tool has just been designed for you. With this tool you can experiment with different combinations of any of the more than 70 3D transitions available, and its 50+ marvelous effects. One of its main assets is the built-in video player, so you can preview, watch, and listen to your creations without the need of external tools. It also offers you the possibility of changing the frame size and the frame aspect ratio, of cutting and joining your files, of mixing audio and video files together, and, of course, of converting them from one codec to another. The cut and join feature allows you to select the start and end frames while watching the video.
Most of these features are available in the trial version reviewed here, which is available free of charge. This tool is compatible with most Windows operating systems.
