XEffects Five Star Rating is a title plugin for Final Cut Pro that displays a rating of stars onscreen. Perfect for rating any product, service or location, the user can set a rating between zero and five stars in half star increments.
This free FCP plugin is fully customisable for size, position and colours.
The plugin is made from vector graphics, so you can make it as large as you like. To make an animating star rating, just wipe between two instances of the plugin.
