Press Shift + Command + 5 to open the recording toolbar. Choose the entire screen or a selected portion; recording a selected window is available on macOS Tahoe 26 or later.
Open Options before recording. On supported Macs running macOS Tahoe 26 or later, the capture-format choices are SDR (Most Compatible), which uses H.264, and HDR, which uses HEVC.
Capture-format choices on supported Macs with macOS Tahoe 26 or later| Capture option | Codec | For this GIF converter |

| SDR (Most Compatible) | H.264 | Choose this option |

| HDR | HEVC | Re-export as SDR H.264 first |

This choice matters even if both files play normally on your Mac. The GIF converter accepts supported 8-bit SDR H.264 files and explicitly rejects HEVC and HDR input. When the capture-format selector is available, choose SDR before you record. If it is absent, do not assume your Mac has the same controls; check the saved file in the converter instead.
Options also controls the microphone, visible mouse clicks and save location. Recordings save to the desktop by default, with a .mov filename. Stop from the menu bar or press Command + Control + Esc. QuickTime's File → New Screen Recording command (Control + Command + N) may open the same toolbar or its older recording window.

Already have a file that needs H.264?
In QuickTime Player, use File → Export As. For a 1080p or 4K export, select Greater Compatibility to use H.264 when the format menu is shown. QuickTime also documents H.264 for 720p and 480p exports. The exported file is still a .mov; changing its filename to .mp4 is not a codec conversion.
Choose an SDR H.264 export when the source is HDR, then reopen it in the converter. A smaller output frame size in the GIF settings does not make an unsupported source codec decodable.
