A–B loop guide

How to Loop Part of a YouTube Video

Mark the exact beginning and end of a YouTube section, then let LoopVideo return to that range automatically.

Paste a valid link and the practice studio opens automatically.

Quick answer

Paste an embeddable YouTube link, tap the video thumbnail, play to the start and press Set A, then play to the end and press Set B. Use the A and B fields or the ±0.1-second controls to refine the range.

How to loop one part of a YouTube video

  1. 1

    Paste the YouTube link

    A valid link opens the real LoopVideo workspace automatically.

  2. 2

    Tap the thumbnail and find the start

    Start the embedded player. When the section begins, press Set A.

  3. 3

    Mark the end with Set B

    Continue playing and press Set B where the section should return to A.

  4. 4

    Fine-tune and copy the link

    Adjust either point by 0.1 seconds, then use Copy link to preserve the supported loop settings.

Three ways to set a precise range

Use Set A and Set B while listening, drag the A–B timeline, or enter times in the A and B fields. The separate fine-tune buttons move either boundary by 0.1 seconds.

Reopen the same practice range

Copy link creates a LoopVideo URL containing the video and supported loop state. Saved loops stay only in the current browser.

YouTube playback still sets the limits

The video must permit embedding and have a fixed duration. Private, removed, age-restricted, embedding-disabled, and live videos may not work. Returning to A can include a small seek delay.

Frequently asked questions

Can I enter exact start and end times?
Yes. Enter A and B in seconds or use the 0.1-second fine-tune controls. YouTube seeking can still include a small delay, so LoopVideo does not claim frame-perfect boundaries.
Can I loop part of any YouTube video?
Only uploaded videos that are available and permit embedding can play in LoopVideo. Live, private, removed, restricted, or embedding-disabled videos may not work.
Can I share the exact section?
Copy link preserves the supported video and loop state in a LoopVideo URL. Save stores a loop only in the current browser.
