How to trim a video on Windows, frame-accurately, without an editor
You do not need a video editor to cut a boring start or a long ending. Timeline trims right inside the player.

When trimming is the right tool
Trimming keeps one continuous part of a video and drops the rest. It is the tool for the everyday jobs: cutting the dead air before a recording starts, removing the end of a clip, or pulling one good minute out of a long file so you can send it.
It is not an editor. You cannot join clips or add effects. What you get is quick, exact and does not need anything else installed.
Trim a video step by step
- Open the video in Timeline and press CtrlS to open the player settings.
- Switch Trimming on (the scissors icon). The seek bar turns into a trim bar with a handle at each end.
- Drag the start handle to where you want the new video to begin, and the end handle to where it should finish. When you let go of a handle, the video jumps to that point so you can check the frame.
- In the Trim panel (bottom right) you see the start, the end and the length of the new file. Type a file name if you want a different one.
- Click Save trim. Timeline asks which folder to put the new file in.
- Watch the progress bar at the top left. When it is done you get a pop-up from Timeline.
Tip. For small corrections, click a handle and nudge it with the arrow keys: each press moves it a tenth of a second, and Shift with an arrow moves it a whole second. Cancel in the panel leaves trim mode without saving.
While you trim, the hover preview card is off, so it never covers the handles.

Why frame-accurate matters
Many quick cutters can only cut at certain points in a video, so your cut lands a little before or after the spot you chose. Timeline trims at the frame you pick. That matters for a short clip: a half-second of extra footage at the start is the difference between a clean clip and one that begins with the wrong moment.
To check a spot before you commit to it, use frame stepping to look at the frames around it. It is also how you find the exact moment you want to cut at.
Your original file is safe
Saving a trim writes a new file. The original video is not changed or replaced, so you can trim the same video again with different handles at any time.
Trim your own recordings and clips
Timeline's recorder saves its recordings and replay-buffer clips as ordinary video files, so you can open one in the player and trim it straight away. A common routine is to press the clip hotkey, open the clip from the pop-up, trim a few seconds off each end, and share it with compress and upload.
Careful. In a watch together session a guest cannot trim, because a guest does not have the file on their own PC.
Questions
Does trimming change my original video?
No. Timeline saves the trimmed part as a new file and leaves the original as it was.
Can I trim audio files?
Trimming is built around video files. Open a video, switch Trimming on and follow the steps above.
Where does the trimmed file go?
Timeline asks you to choose a folder when you click Save trim, and it opens the folder you used last time.
Can I cut a piece out of the middle?
Trimming keeps one continuous part. To remove a section from the middle you would trim twice (before and after it) and join the pieces in an editor.
