| Scaler | Sharpness | Ringing | Best Use Case |
|---|---|---|---|
| ewa_lanczossharp | ⭐⭐⭐⭐ | Low | Best General Upscaler. The "Gold Standard". Sharp but clean. |
| spline64 | ⭐⭐⭐⭐⭐ | Medium | Best Downscaler. (SVP Choice). Retains maximum 4K texture on 1080p. |
| lanczos | ⭐⭐⭐⭐⭐ | High | Classic Sharp. Very crisp, but creates halos. For "crunchy" image lovers. |
| spline36 | ⭐⭐⭐ | Low | Best Chroma Scaler. Perfect balance for color. High quality, zero artifacts. |
| mitchell | ⭐ | None | Smooth. Soft scaler that hides compression. Good for downscaling. |

v4.9 adds a dedicated Open File button to the UOSC controls bar. It opens UOSC's file-selection menu directly inside MPV for quick video and audio selection.
If your video folders contain poster, backdrop, thumbnail, or other image files, keep the browser focused on playable media with:
load_types=video,audio
show_hidden_files=no
image_types=This prevents image assets from appearing in the Open File menu while keeping video/audio selection available.
This build is the perfect "Engine" for high-quality streaming. We recommend these apps for the best 4K HDR and Anime Tracking experience.

Configurable display-to-device audio mappings in auto_audio_device.conf for Linux, Windows, and macOS, featuring human-readable EDID and monitor-name identification.
Browse, filter, and jump to lines of dialogue across subtitle tracks with mpv-subtitle-lines, a contextual UOSC button, and CTRL+f shortcuts.
Accurate context-aware shader reporting in CTRL+i, expanded glass panel layout, unified Microsoft Sans Serif OSD fonts, and balanced interface font scaling.
External controllers keep their IPC endpoint while SVP and discovery-based integrations can attach through a shared per-process alias on Unix systems.
The upstream UOSC self-updater is removed so it cannot overwrite Anime Build menus and integrations. Manual build checks now open the exact GitHub release page.
Release ZIPs receive SHA-256-specific VirusTotal reports without replacing the handwritten release description.
Explicit Live-Action path and title markers once again override Anime folder and Japanese-audio signals in Auto mode, selecting the correct resolution-aware profile.
Thumbfast now ships with software decoding enabled for its helper process, avoiding hardware-decoder compatibility problems during thumbnail generation.
yt-dlp subtitle requests now stay limited to English and original-English tracks, removing unintended Telugu language requests.
The complete Low-End profile stays active across file and metadata changes, while remembered preferences return safely when Power Saving ends.
Automatic selection skips commentary, preserves clean-track priority, and falls back to a complete SDH track when no usable clean subtitle exists—even without preferred-language metadata.
Windows DisplayConfig and KDE Plasma KScreen detection are isolated by platform, while other Linux compositors use mpv's native colorspace negotiation.
UOSC Controls and HDR selections persist in update-safe user-<custom-name>.conf files and are reapplied after automatic profiles.
One update-safe mpv-<custom-name>.conf file can override normal options from the shipped mpv.conf on Windows and Linux.
Resolved disabled track overrides, Linux peripheral batteries triggering Eco mode, and startup profile conditions receiving incomplete metadata.
The two adjacent Anime shaders now use explicit anime_mild and anime_aggressive filenames, with saved legacy paths migrated automatically.
Optimized anime_profile_controller.lua and main.lua to fix minor bugs, reduce unnecessary processing, and improve state handling.
A new Open File control opens UOSC's native file-selection menu directly from the player for quick video and audio selection.
