Background Video

It seems like you're interested in background video or imagery in the context of Apple's WWDC sessions. Here are some relevant insights from the sessions:

1. Migrate your TVML app to SwiftUI: This session discusses how to handle background images in a SwiftUI app for tvOS. It covers techniques like using a gradient mask to fade out images behind buttons and using new view modifiers in tvOS 18 to manage background visibility as content scrolls. This can be particularly useful for creating visually appealing interfaces where background images play a significant role. You can find more about this in the Catalogs chapter.

2. Design great visionOS apps: This session highlights the importance of balancing branding with usability, especially when using background colors or images. It suggests using high-quality visual imagery to incorporate branding without compromising user comfort or usability. This is particularly relevant for apps on Vision Pro, where solid backgrounds can be visually distracting. More details can be found in the Comfortable chapter.

3. Optimize for the spatial web: This session introduces the element fullscreen API, which allows media to be displayed in fullscreen mode, making it the only content on the screen. This can be particularly useful for spatial photos or videos, ensuring they are shown at the correct visual scale. This is discussed in the Media content chapter.
