How to Split a Video for YouTube

To split a video for YouTube , meaning cut a section out of the middle of one that's already published , open Trim & cut in the Studio Editor and use the red box. The blue box marks what you keep; the red box marks what disappears.

Split a video for YouTube with the red box

Under Content, click the video, open Editor, then Trim & cut. Drag the sides of the red box until it covers exactly the passage you want gone. For a second section, click New Cut and place another red box. A video with three problems takes three boxes in one editing session, not three separate edits.

The reason to do this in Studio rather than re-uploading is what survives: after the edit, the video keeps its URL, its view count and its comments. Everything a re-upload would throw away stays where it is.

Choosing where a Short begins

Splitting has a smaller cousin in the Shorts camera. The Trim tool there lets you choose the starting point and trim video segments. Useful when the first second of a take is you reaching away from the phone, and re-recording the whole thing would be absurd.

It sets entry and exit points rather than removing an interior chunk, so it solves a narrower problem than the red box does. But it solves it before publication, which is always the cheaper moment.

Splitting and then reordering

Studio can remove a section. It can't move one.

Montaj keeps a real timeline, so a split is the start of a decision rather than the end of one: cut a clip into pieces, drag the pieces into a different order, split again, and walk any of it back through 100 steps of undo. The footage stays on your device the entire time — nothing is uploaded while you're rearranging it. That's the difference between editing and the surgical version of splitting a video for YouTube after it's already live.

How to cut a section out of a YouTube video in 4 steps

  1. 1

    Open Trim & cut on the published video

    In YouTube Studio, open the video under Content, choose Editor, then click Trim & cut. The blue box marks what you keep; the red box marks what goes.

  2. 2

    Drag the sides of the red box over the section to remove

    Position it so the red box covers exactly the part you want gone. Everything outside it stays.

  3. 3

    Click New Cut for each additional section

    One red box removes one section. New Cut adds another, so a video with three bad patches takes three cuts rather than three separate edits.

  4. 4

    Save, knowing what survives

    After the edit the video keeps its URL, its view count and its comments. Only the footage changes.

The verdict

The red box is genuinely good at one job: excising a mistake from a video that already has an audience, without losing the comments underneath it. Don't mistake it for editing, though. Every cut is permanent, they add up quickly, and there's no way to move one after the fact. Two or three surgical removals, yes. Restructuring a video, no. That's a re-edit and a re-upload.

Frequently asked questions

How do I split a video for YouTube to remove a section from the middle?
Use Trim & cut in the Studio Editor. Drag the sides of the red box over the part you want removed, and click New Cut to add another red box for each further section.
How do I cut a video into parts on YouTube?
Studio removes sections rather than producing separate files. To publish the parts as individual videos, split the source in an editor and upload each piece.
Does editing a published video reset its views or comments?
No. After a Trim & cut edit, the video's URL, view count and comments all stay the same.
How do I pick where a Short starts?
The Shorts camera's Trim tool lets you choose the starting point and trim video segments, so you can set the entry point without re-recording.
