# Video formats and codecs, explained for wallpapers

Containers versus codecs, which combinations macOS decodes in hardware, and the exact export settings that make a great live wallpaper loop.

Two things get conflated constantly. The **container** is the file wrapper — `.mp4`, `.mov`, `.mkv`, `.webm`. The **codec** is how the picture inside is compressed — H.264, HEVC, ProRes, AV1, VP9. The extension tells you the container; it does not tell you the codec, and the codec is what determines whether your Mac decodes efficiently.

## Containers you will meet

- **MP4** — the universal choice. Broad support, small overhead, works everywhere.
- **MOV** — Apple's container. Functionally similar to MP4 and the default from Final Cut and QuickTime.
- **M4V** — an MP4 variant from the Apple ecosystem.
- **MKV** — flexible and popular for archiving, but the least predictable for native macOS playback.
- **WebM** — a web container, usually carrying VP9 or AV1. Poor fit for macOS wallpapers.

## Codecs, ranked for this job

1. **HEVC (H.265)** — best size-to-quality ratio, hardware decoded on modern Macs. First choice.
2. **H.264 (AVC)** — slightly larger at equal quality, hardware decoded on everything. Safest choice.
3. **ProRes** — beautiful and enormous. Fine as a master, wasteful as a wallpaper.
4. **AV1** — excellent compression, but hardware decode only on the newest Apple silicon.
5. **VP9** — typically software decoded on macOS. Avoid.

## Export recipe for a wallpaper

- **Container**: MP4.
- **Codec**: HEVC, or H.264 if you want maximum compatibility.
- **Resolution**: match your display — 3840×2160 for a 4K panel. Never encode above it.
- **Frame rate**: 24–30 fps. Ambient motion gains nothing from 60.
- **Bitrate**: 8–15 Mbps at 4K is plenty for the slow footage that makes good wallpaper.
- **Colour**: Rec. 709, SDR. HDR wallpapers can look washed out or oddly bright next to standard UI.
- **Audio**: remove the track entirely.
- **Duration**: 5–30 seconds, looping cleanly.

## Making the loop seamless

1. Pick footage with no strong directional change — drifting fog, rain, gentle particle motion, slow pans.
2. Trim so the first and last frames are visually close.
3. Crossfade the final half-second into the opening half-second, or mirror the clip for a ping-pong loop.
4. Preview it looping for a full minute before you commit. Loop points you barely notice once become obvious after ten repeats.

## Frequently asked questions

### Is MP4 or MOV better for a live wallpaper?

They perform the same on macOS. What matters is the codec inside. MP4 is the more portable wrapper, so prefer it unless you have a reason not to.

### Should I use a 4K file on a 1080p display?

No. You pay extra decode cost for detail the panel cannot show. Encode at the resolution you will actually display.

### Can I use a GIF as a live wallpaper?

You can, but GIF is a terrible video codec — huge files, 256 colours, no hardware decode. Converting to an MP4 loop looks better and costs less.
