How to Trim a Video

Use the built-in player to preview the video and identify the section you want.
Enter the start and end times in mm:ss format (e.g., 01:30 for 1 minute 30 seconds).
Load the FFmpeg engine, then click "Trim Video".
Download your trimmed video clip.

Key Features

Fast stream copy: Uses codec copy mode to trim without re-encoding for instant results.
No quality loss: The original video and audio streams are copied exactly.

What does "stream copy" mean?

Stream copy mode cuts the video without decoding and re-encoding it. This is extremely fast and preserves the original quality, but the cut points are limited to keyframes in the video.
