Multi-asset editing Stay organized with collections Save and categorize content based on your preferences.

Using Transformer, you can combine multiple media assets, such as videos, images, and audio files into a single video. To get started, learn about arranging your input media items into a Composition, Media3's representation for multi-asset editing projects. You can then preview your project with CompositionPlayer, or export the Composition with the Transformer API.
