Four Ambient Wallpapers with 4K Super-Resolution
The morning, day, dusk, and night wallpapers on desktop Home now have subtle seamless loops of about five seconds generated locally with MiniMax H3. Motion is limited to restrained tree-canopy and real-water changes, alongside the existing slow clouds and faint night stars. Only the current theme requests a 1080p or 21
# Four Ambient Wallpapers with 4K Super-Resolution
All four periods on desktop Home now carry a small amount of environmental motion. The goal is not to make the page feel like a conspicuous video, but to let the pixel scene breathe without competing with windows or text.
## Restrained loops of about five seconds
- Morning, day, dusk, and night each use a seamless loop of about five seconds generated locally with MiniMax H3.
- H3 changes are taken only from small tree-canopy and real-water regions. The city, sky, slope, ground, and television remain stable.
- The existing CSS clouds continue their slow drift, while night adds only faint starlight without frequent flashing.
## 4K clarity without upscaling every frame
Each theme's static base is super-resolved once with the official `RealESRGAN_x4plus_anime_6B` model. A smoothed and gain-limited local H3 temporal delta is then composited on top. This keeps static detail clearer on 4K displays without introducing the edge and texture flicker that can appear when every frame is independently super-resolved.
## Loading only the one file needed now
The page selects a 1080p or 2160p file for the current theme from its physical display size and does not preload the other three periods. Video fades in only after playback is ready; if loading fails, the original static wallpaper remains. Mobile, low-performance, Save-Data, `prefers-reduced-motion`, and in-site reduced/off modes make no video requests at all. Playback also pauses while the page is hidden.
