VideoClipper is a program for cutting and optionally joining various format video files while converting the files to a common format. During a conversion several adjustments (Video Effercts) can be made to the individual files. These effects include adjusting brightness,contrast, gamma. Additional effects include applying sharpness or blurring along with adjusting the speed (fast/slow motion) and rotation. You can also add a subtitle and audio file to the joined video. VideoClipper uses ffmpeg to cut/join, convert and apply effects to the video files. In addition it uses mplayer to preview cuts and changes as well as view the results. VideoClipper version 2.1 adds many features which make it easier to preview the full video, instead of one file at a time, and makes it easier to find frame accurate edit points in both forward and revers directions.
