A fifteen-second clip that loops forever — a product demo, a fireplace ambience, a fitness routine to follow. Looping seems trivial until an app or player insists on stopping at the end. Here's how to loop a video in every common context.

What "looping" means

Loop = automatically restart from the beginning when playback ends. Three different things get called looping:

1. **Player loop** — the player repeats the file (nothing changes in the video itself) 2. **Embedded loop** — the video element on a webpage has the loop attribute set 3. **Baked loop** — the file itself contains the sequence repeated, or is converted to a GIF that inherently loops

Each fits a different situation.

Player loop: where you control playback

- **YouTube:** right-click the video → Loop. Applies to that video in that tab. - **VLC (desktop):** Playback → Loop once (loops the current file). VLC loops anything it plays, forever. - **Phone players:** most default gallery apps don't offer loop. Players like VLC mobile or MX Player do — look for the repeat button in the playback controls. - **Browsers on a raw file:** right-click an HTML5 video → "Loop" if the browser exposes it (Chrome does).

This is the zero-effort answer whenever you're the one watching.

Embedded loop: when you publish the video

If you embed video on a page you control, add the loop attribute:

<video src="clip.mp4" loop autoplay muted></video>

`loop` restarts playback, `muted` + `autoplay` let it start without user interaction (browsers block unmuted autoplay — this is why muted looping backgrounds are everywhere). This is the standard pattern for hero backgrounds, product showcases, and ambient sections. If you host on a video platform, look for a loop or autoplay-repeat option in the embed settings — many hosts expose a toggle that sets it server-side.

Baked loop: making the file itself repeat

When the video must loop everywhere — chat apps, presentations, any player — bake the repetition in:

**FFmpeg concat:** create a file listing the clip N times, then concatenate:

ffmpeg -f concat -i list.txt -c copy looped.mp4

With `-c copy` this is instant and lossless. A 15-second clip repeated 20 times becomes a 5-minute video with zero quality loss.

**Boomerang-style ping-pong:** append a reversed copy so the clip plays forward-backward-forward:

ffmpeg -i in.mp4 -filter_complex "[0:v]reverse[r];[0:v][r]concat=n=2" out.mp4

This re-encodes (slower) but produces the seamless bounce made famous by Instagram's Boomerang.

GIF conversion: the universal loop

GIFs loop by default everywhere. Convert when the clip is short, silent, and small:

ffmpeg -i in.mp4 -vf "fps=12,scale=480:-1" out.gif

- `fps=12` and 480px width keep the file sane (GIFs are inefficient — a 10-second clip easily exceeds 10 MB) - No audio in GIFs: they're silent by format

For looping with sound, stay with video; for looping memes and micro-animations, GIF is still the lingua franca.

Digital signage and kiosks

Screens in shops and lobbies need all-day loops. The robust setup: a playlist of one video set to repeat, played by a dedicated player (VLC in loop mode, or the display's built-in USB player with repeat enabled). Devices like Chromecast work but depend on the casting phone staying alive — local playback on the screen itself is the reliable choice for unattended setups.

The takeaway

Player loop when you're the viewer (VLC or YouTube right-click). The loop attribute when you embed. FFmpeg concat or ping-pong when the file itself must repeat. GIF when it's short, silent, and headed for a chat.
