Loop a section of a YouTube video

Paste the link, drag two handles around the part you want, and it repeats — that's it. Free, in your browser, no signup, and you can slow the loop down (0.25×–2×, pitch unchanged) while you're at it.

How it works

  1. Paste a YouTube link. Any video that allows embedding plays here, through YouTube's own player.
  2. Drag two handles. Mark the start and end of the section on the timeline — down to fractions of a second. The loop repeats until you stop it.
  3. Optionally, slow it down. Speed steps from 0.25× to 2× with the pitch preserved, so a slowed loop still sounds like the recording, just slower.

Keyboard shortcuts if you're at a desk: space to pause, arrows to nudge, number keys to jump. On a tablet or phone, everything is drag and tap.

Not just for musicians

A section loop is a general-purpose tool, and people use this one for all of it: musicians drilling a solo, dancers running one 8-count of a practice video, language learners replaying a sentence until the sounds separate, athletes and coaches re-watching one movement in a match or technique video. If the thing you need to absorb lives in twelve seconds of a longer video, looping those twelve seconds beats scrubbing back forty times.

The difference: your loops are still there tomorrow

Most YouTube loopers do the loop and nothing else — close the tab and the timestamps are gone. That's fine for a one-off. It's quietly maddening for anything you'll come back to, because every session starts with re-finding the spot and re-setting the speed.

Stairway2Fast keeps the record. Every video remembers its loops — name them ("solo bars 3–4", "dance break", "dialogue at 2:10") and each one reopens with one tap, at the speed you left off. And if you're using loops to practise something, the time logs itself: how long you spent, on which section, at what speed. After a couple of weeks you can see the climb — the section you started at 0.6× and finally broke 0.9× on. Streaks, daily goals, per-video history — all recorded from what you actually did, not what you remembered to write down.

Free vs Pro, honestly

Looping, slow-down, named loops, and all the practice tracking are free, with no account — including uploading your own recordings (lessons, rehearsals, your own playing) and looping them the same way; uploads stay on the device you added them on. Sign up (also free) and your library and history sync across devices. Pro (£4.99/$6 per month) adds cloud sync so your uploads follow you too.

FAQ

How precise can the loop be?

Down to fractions of a second. The handles are draggable and nudgeable, so "the second half of bar 12" or "one spoken sentence" is a realistic loop.

Does slowing the loop change the pitch?

No. Playback uses pitch-preserving time-stretch, so an A stays an A at 0.5× — no chipmunk-in-reverse effect.

Do I need an account?

No. Open the app and loop as a guest — loops, speeds, and history are kept in your browser. Create a free account when you want it synced across devices; everything migrates automatically.

Is this allowed by YouTube?

Yes. The video plays in YouTube's own embedded player, and speed/loop control uses YouTube's public, documented player API. Nothing is downloaded, ripped, or re-hosted.

Can I loop any YouTube video?

Any video that allows embedding — nearly all do. If a channel has disabled embeds, YouTube blocks playback outside youtube.com; no looper can change that.

Can I save more than one loop per video?

Yes — save and name as many sections as the video needs. A long lesson or a full routine becomes a menu of named loops, each remembering its own speed.


Stop scrubbing. Paste the link, frame the section, and let it repeat — and find it still waiting for you tomorrow.
