How do I loop a specific part of a YouTube video?

Quick answer

YouTube's player has no option to loop just one part, so use an A–B looper. On RepeatWatch, paste the link, drag the A handle to where the part starts and the B handle to where it ends. The section then repeats on its own. You can also press A and B on your keyboard while it plays.

How to loop part of a YouTube video

  1. Open the video. Paste the YouTube link into RepeatWatch.
  2. Set the start point (A). Drag the blue A handle on the timeline, or press A on your keyboard at the moment the part begins.
  3. Set the end point (B). Drag the red B handle, or press B when the part ends. The section between A and B now repeats.
  4. Fine-tune the edges. Type exact times such as 1:23.5, or use the −0.1s and +0.1s buttons to move a point by a tenth of a second.
  5. Save it for later. Press S or choose Save section, then give the part a name so you can loop it again in one click.

Try it now: paste a YouTube link.

What is an A–B loop?

An A–B loop repeats only the stretch of a video between two points: A, where the loop starts, and B, where it ends. When playback reaches B, it jumps back to A. Musicians, dancers and language learners use it to practice one short part.

Can I share a loop of part of a YouTube video?

Yes. Choose Copy loop link and send it. The link opens at the same A and B points and speed. For example, repeatwatch.com/?v=VIDEO_ID&a=43&b=60 loops from 0:43 to 1:00.

How do I loop several parts of the same video?

Save each part as a named section, like Intro, Chorus or Solo. You can also paste chapter timestamps from the video's description to create every section at once, then press 1 to 9 to jump between them.

Which keyboard shortcuts help with A–B loops?

RepeatWatch has a shortcut for every loop control, so you can keep your hands on your instrument or keyboard.

  • A sets the start and B sets the end
  • R jumps back to the start of the loop
  • L turns repeat on or off
  • Comma and period move a tenth of a second
  • S saves the loop as a section

Frequently asked questions

How short can a loop be?

On RepeatWatch a loop can be as short as half a second. For very short loops, set the points by typing times or nudging them by 0.1 seconds rather than dragging.

Can I loop part of a YouTube Short?

Yes. Paste the Shorts link and RepeatWatch opens it in the same player, so you can loop any part of a Short just like a normal video.

Can I loop part of a video on my phone?

Yes. RepeatWatch works in mobile browsers. Drag the A and B handles with your finger, or type the start and end times in the Loop tab.
