GUI for FFmpeg

 This is a free and open source media converter frontend to FFmpeg. FFmpeg
 is a powerful command-line utility to convert audio and video file into
 numerous formats. QWinFF features a rich set of presets to help users use
 FFmpeg easily without having to manually input command-line flags. Average
 users can convert multiple media files in just a few clicks, while advanced
 users can still adjust conversion parameters in detail.
