Like DVD, Blu-ray allows multi-angle viewing, giving viewers the ability to observe different perspectives of the same scene using the Angle button on the remote.

This feature is made possible through the use of multiple viewpoints in one stream, enabling users to easily switch between them and explore the scene from various angles. Users can also use the angle buttons to see different versions of the same scene like storyboards or previsualizations. It supports a maximum of up to 9 camera angles.

Alita: Battle Angel offers multi-angle using colored buttons to view the stages of production of the same scene.

Despite being a cool additional feature, it's not used often anymore in mainstream releases. Today, it's a niche in markets such as yoga, martial arts, erotica, animation (e.g. for storyboards), and live performances.
