Trim Video
Cut a video to a specific start time and duration.
Enter a start time in seconds and a duration to extract that segment of the video.
Trimming is the most fundamental video edit — extracting the best part from a longer recording. Whether you need to cut out the intro of a meeting recording, extract a highlight from a sports clip, or save a specific moment from a long video, trim gets you there without a full video editor.
We use ffmpeg's fast seek mode for the start point, which jumps to the nearest keyframe before your specified time and then precisely trims to the exact second. This makes trimming fast even on large files.
Use decimal seconds for sub-second precision — "30.5" means thirty and a half seconds in. The duration parameter works the same way: "10.5" extracts a ten-and-a-half second clip.
How to use Trim Video
- Step 1: Upload your video (MP4, WebM, MOV, or AVI).
- Step 2: Enter the start time in seconds (e.g. "30" for 30 seconds in, or "1.5" for one-and-a-half seconds in) and the duration of the clip you want in seconds.
- Step 3: Click "Convert now" and download the trimmed MP4 segment.
