When using media assets in video editing, there is a general challenge of adapting the duration of an element to the desired duration in the video. For example, a pre-rendered animated element might last for five seconds and is not usable for durations shorter or longer than five seconds. This disclosure describes techniques to structure pre-rendered media elements in a specific format that enables a hosting application to control how they appear and behave. Per the techniques, pre-rendered media elements are provided in a format that enables control over their properties such as duration, palette, color, etc. A video creator can use the controls to match the pre-rendered element to the video it is being embedded in.
