Choose a window, screen or region for a recording

A single-window demonstration stays inside one application window. A workflow involving a document, a browser and a file dialog may need more space. A fixed region is useful for a stable part of the screen, but anything that moves outside it can be lost.

Apple’s Screenshot controls offer whole-screen and selected-portion recording, with selected-window capture documented for macOS 26 or later. These are Apple’s controls, not a description of every Mac recorder. Confirm the options in the app and version you are actually using.

Before deciding on a crop, perform the actions that change the layout: open a menu, expand a sidebar, show an error, invoke a file chooser and scroll to the final result. An interface that fits at the beginning may not fit halfway through.

Imagine a spreadsheet lesson where the cell is visible but the formula bar is outside the capture. The video shows clicks without the information needed to understand them. Widening the capture slightly can be more useful than maximizing the apparent size of the selected cell.

Reel on Mac records a display. Its setting for including its own application does not establish an arbitrary third-party window-selection feature. If you need a strict individual-window workflow, choose a recorder with that documented capture mode rather than assuming the option exists in Reel.

Prepare the chosen display deliberately: close irrelevant material, arrange the working windows and reduce interruptions. A Focus can help manage notifications, but neither a selected window nor a clean desktop should be treated as a guarantee that no sensitive information will appear.

1. List every window, dialog and result that the viewer needs.
2. Choose screen, window or fixed region in a recorder that supports that mode.
3. Record a brief rehearsal that includes menus and window movement.
4. Watch the saved output and check all four edges at the important moments.
5. If needed, change the capture area or redesign the demonstration before the full take.

If a demonstration genuinely needs several windows, do not squeeze them into unreadable tiles solely to keep one small region. Show the steps sequentially or use separate takes with a clear transition. The viewer needs to know where the next action happens.

Cropping after capture can help with an untidy border, but it cannot recover a dialog that never entered the recorded area. Keep the original until the final delivery has been checked, and distinguish capture selection from editorial cropping when explaining your workflow to collaborators.
