Recording quality: 720p, 1080p or 4K

720p at 60 fps

The lightest option: the same smooth 60 fps, about 4.5 GB an hour (half of 1080p), and the phone runs cooler and uses less battery. Pick it when space is tight, on an older iPhone, on a hot day, or when you're live streaming at the same time. Switch to it in Settings › Recording quality.

1080p at 60 fps (the default)

Smooth motion for fast play and about 9 GB an hour, so a full game fits on most phones and uploads quickly. The cloud streams 1080p, so this is what your team sees anyway.

4K at 30 fps

The sharpest picture, so digital zoom and vertical (9:16) clips keep more detail. It uses about 15.8 GB an hour. Switch to it in Settings › Recording quality.

What gets uploaded

Whichever you record, the cloud copy is 1080p by default, so uploads are a similar size either way. You can choose to upload the original instead. A 720p game uploads as 720p (it's never upscaled).

The web player streams the game at up to 1080p, and the full-game download is a 1080p MP4.
