Prism

Prism is a stable and comprehensive multi-format video file converter. Import a video file, a whole folder of files, or drag and drop your videos into the program. You can then select from a wide variety of video formats that you want to convert your file to including popular formats like FLV, MP4, AVI, MPG, VOB, WMV, and all video formats that have a DirectShow based codec. In minutes, you can compress your videos or convert multiple video files at once with batch conversion. Before you convert, you can optimize your video output by adding effects, desired resolutions, and even text captions and watermarks. Prism can preview your video and all of your changes made before conversion.
