Animate is built around a mouse or trackpad, keyboard shortcuts, and drag and drop. It is not made for phones or tablets.
Chrome, Edge, or Safari from the last two years. Chrome and Safari record straight to MP4; other browsers save WebM. There is nothing to install.
An Apple Silicon Mac or a Windows laptop with integrated graphics from the last five years handles editing fine. Your work autosaves in the browser, so keep using the same one.
Recording captures the canvas live at your screen's full resolution, up to 60 frames a second. On an older or fanless machine it can drop frames. Plug in and close other tabs before you press record. Still images export at 4K on any machine.
