Overview

The Video Trim tool allows you to quickly extract specific segments from your video files with fast, lossless processing. By supporting both high-speed stream copying and high-quality re-encoding, you can easily cut MP4, MOV, MKV, and other video formats down to the exact duration you need.

2Specify the start and end times in seconds to define the exact segment you want to keep.
3Choose your processing mode: select 'Fast' for instant stream copying without re-encoding, or 'Quality' to re-encode the clip.
4Click the trim button to process the video and download your newly extracted segment.
