Video Trimmer cuts out a fragment of a video given the start and end timestamps. The video is not re-encoded, so the process is very fast and does not reduce the video quality.
Here is am image of Video Trimmer in action.
The processing of trimming couldn’t be more simple. Drag the yellow bar to where you want the trimmed video to start and end and hit the trim button. Alternatively you can enter the start and end times manually in the fields at the bottom of the window.
