To render video overlays over other videos, you can explore the capabilities provided by Apple's frameworks, particularly in the context of visionOS. The session titled Explore multiview video playback in visionOS discusses how to bring simultaneous video watching to your app using the multiview architecture. This allows you to display multiple video screens at once, with layout templates that maximize comfort and viewability. You can add, remove, arrange, reposition, and resize videos to create a customized viewing experience.

For more advanced rendering, you might also consider using AV Foundation and RealityKit, which are integrated into Apple's frameworks to handle video playback and rendering. These tools allow you to create immersive media experiences with features like spatial audio and 3D video.

If you are interested in rendering technologies specifically for games or interactive content, the session Bring your iOS or iPadOS game to visionOS covers rendering on visionOS using RealityKit and Metal, which can be used to render content in a volumetric space.

These sessions provide a comprehensive overview of the tools and techniques available for rendering video overlays and creating immersive video experiences on Apple's platforms.
