When exporting cinemagraphs for presentations, we recommend using the default repetitions setting because you will have the option to loop them in Keynote.
Cinemagraph Pro for macOS
Click Export in the toolbar or use the keyboard shortcut (⌘E) to export your cinemagraph.
Cinemagraph Pro for iOS
Select the cinemagraph you want to export in your documents or tap on the back icon to exit the editor. Tap the share icon, Export Cinemagraph and select Save to save the cinemagraph to your camera roll.
Go to the slide you want to add your cinemagraph to and either drag the file onto the slide or insert from the toolbar by going to Media > Choose. Switch to the Movie tab on the sidebar and select Loop under Repeat. If you want your cinemagraph to start playing automatically, uncheck Start movie on click.
