How to trim a video using Lossless Cut
Lossless Cut is a free program that trims videos with no loss of quality (it does not reencode).
Example Lossless use cases
- Cut unwanted intro or outro sections from a Zoom or Kaltura video.
- Remove audio tracks from a file
- Extract music track from a video and cut it to your needs
- Add music to a video (or replace existing audio track)
- Combine audio and video tracks from separate recordings
- Include an external subtitle into a video
- Quickly change a H264/H265 MKV video to MOV or MP4
- Quickly cut a file by its MP4/MKV chapters
- Quickly cut a YouTube video by its chapters (or music times from a comment)
- Attach cover art to videos
- Change author, title, GPS position, recording time of a video
- Fix rotation of a video that has the wrong orientation flag set
- Great for rotating phone videos that come out the wrong way without actually re-encoding the video.
- Loop a video / audio clip X times quickly without re-encoding
- Convert a video or parts of it into X image files (not lossless)
Example: trim the first 10 minutes and last 10 minutes of a video
- Open the video file.
- To cut a portion of the intro, on the green time bar, position the white time line cursor at the spot you want to cut.
- Click the 'Set cut to start position' button.
- This will mark the intro segment with a trash can icon for deletion.
- To cut a portion of the ending, position the white time line cursor at the spot you want to trim.
- Click the 'Set cut end to current position' button.
- This will mark the end segment with a trash can icon for deletion.
- Click the blue Export button in the lower right corner.
- This will bring up the Export Options window. Change any options as needed but we recommend the following:
- Output container format: mp4
- Cut mode: Normal cut (or Keyframe cut if you can't get it to trim exactly where you want it, as the cutting process can shift the frames slightly; you may need to reset your cut point a few frames before to get it to cut on the exact frame)
- Click the blue Export button to output the new file.
