Effect: write (strongest supported action). Status: gated.

Gated means the tool requires an installed app, a connected account, permission, or runtime availability. Check those requirements on the listed platform before using it.

macOS

Purpose

Crops a video to a target aspect ratio (e.g. "9:16" vertical, "1:1" square, "4:5") around a focus point — for social clips. Takes the LARGEST crop of that aspect that fits, centered on `focus` (x,y in source pixels, top-left origin; default = center) and clamped to the frame. Audio passes through. Returns the output path + new dimensions.

Required inputs

input — Path to the source video file.
aspect — Target aspect "W:H", e.g. 9:16, 1:1, 4:5, 16:9.

Permissions and confirmation

No explicit confirmation parameter is exposed in this snapshot. This does not grant permission to act: obtain user authorization before any real action.

Use only the apps, accounts and resources authorized by the user on this platform. Consult this tool's platform-specific description for its connection and permission requirements; this catalog does not assert additional OAuth scopes or OS entitlements.
