First-Version H3 Wallpapers at 48fps and 4K
The morning, day, dusk, and night wallpapers on desktop Home now use the user-approved first-version full-frame MiniMax H3 motion instead of the second version's local mask/gain composite. Each clip is arranged as a full-frame ping-pong loop, bidirectionally optical-flow interpolated to 48fps and 248 frames, then super
# First-Version H3 Wallpapers at 48fps and 4K
All four periods on desktop Home now officially use the user-approved first-version MiniMax H3 source frames. They retain the first version's subtle full-frame changes across trees, clouds, water, and light instead of applying the second version's overly weak local mask/gain composite.
## Full-frame ping-pong loops from version one
- Morning, day, dusk, and night are built from first-version H3 source frames, arranged as source frames 0..62 + 61..1 for the ping-pong loop.
- Each loop lasts about 5.17 seconds, ending at 48fps and 248 frames.
- This release contains no girl and no random television cameo.
## Interpolation first, then per-frame super-resolution
The first-version ping-pong source enters bidirectional optical-flow interpolation at 24fps. After interpolation to 48fps, all 248 frames are AI super-resolved with `RealESRGAN_x4plus_anime_6B`, producing separate 1920×1080 and 3840×2160 outputs. The production pipeline no longer uses the second-version approach of super-resolving one static base and compositing a local masked, gain-limited delta.
## Playback and fallback boundaries are unchanged
The page still selects only the current theme's 1080p or 2160p file from physical display size. Video remains muted, looped, and playsinline, with a short fade only after playback is ready. Mobile, low-performance, Save-Data, `prefers-reduced-motion`, and in-site reduced/off modes still make zero video requests. Leaving Home or hiding the page still pauses or releases video, the static wallpaper remains the permanent fallback, and the earlier BFCache recovery fix remains in place.
