Trim Video
Cut a video down to an exact start time and duration, without re-encoding.
Pulling a short clip out of a longer video — a highlight from a game recording, a specific moment from a longer meeting recording, or trimming dead air from the start and end of a screen capture — is one of the most common quick video edits, and doesn't need a full editing timeline to accomplish.
This tool cuts your video to an exact start time and duration using stream copying rather than re-encoding, which means trimming happens almost instantly regardless of video length, since ffmpeg is just extracting the relevant portion of the existing encoded data rather than decoding and re-encoding every frame. The tradeoff of stream-copy trimming is that cut points snap to the nearest keyframe, so the exact start of your trim may shift by a fraction of a second on some videos — a standard characteristic of fast, non-re-encoding trims.
Processing runs entirely in your browser using a real ffmpeg engine, so there's no upload and your video never leaves your device.

Frequently asked questions
Common mistakes to avoid
- Entering an invalid time format — use HH:MM:SS consistently (e.g. 00:01:30 for 1 minute 30 seconds).
- Setting a duration longer than the remaining video length after the start time, which simply trims to the end of the source video.
