GUIDE从第一块遮挡开始Start with your first mask

快速指南Quick guide

不用先读完所有功能。安装后记住三个动作，就可以把正在看的视频变成一次听力练习。You do not need to learn every feature first. Three actions are enough to turn the video already on your screen into a listening session.

四步开始Start in four steps

  1. 安装并选择语言Install and choose your language

    从官网下载页获取经过签名与哈希校验的正式安装包。正式安装包发布后，安装程序会先询问安装语言；确认后，后续安装页面与首次使用教程会使用你选择的语言。Get the signed, hash-verified installer from the official download page. Once released, Setup asks for the installation language first, then uses your choice for the remaining pages and first-run guide.

  2. 按 ALT + X 框住字幕Press ALT + X and frame the subtitles

    打开视频，按下 ALT + X，拖出要遮住的区域。松开鼠标后，一块遮挡会留在画面上方。Open a video, press ALT + X, and drag over the area you want to cover. A mask remains above the video when you release the pointer.

  3. 按 ALT + S 随时收放Press ALT + S to hide or restore

    ALT + S 可以恢复上次布局，也可以隐藏或显示现有遮挡。没有遮挡时，它会恢复上次布局或建立默认遮挡。ALT + S restores your last layout and hides or shows existing masks. If no mask exists, it restores the previous layout or creates a default one.

  4. 用方向键切换，右键调整Toggle with arrow keys, adjust with right-click

    有上下两块遮挡时，按 ↑ 或 ↓ 切换对应遮挡。右键遮挡可打开操作菜单；也可以按住右键直接拖动，或右键后再用左键拖动。With upper and lower masks, press ↑ or ↓ to toggle the corresponding mask. Right-click a mask for its menu; you can also hold the right button and drag, or right-click first and then drag with the left button.

正式安装包目前尚未开放。发布后，请只从官网下载页获取，并核对页面公布的签名、版本与 SHA-256。The production installer is not available yet. Once released, obtain it only from the official download page and verify the published signature, version, and SHA-256.

最常用的快捷键Essential shortcuts

  • ALT + X — 框选并新建遮挡Select an area and create a mask
  • ALT + S — 恢复、隐藏或显示遮挡Restore, hide, or show masks
  • ↑ / ↓ — 切换上方或下方遮挡Toggle the upper or lower mask
  • ALT + 1 / 2 / 3 — 控制原文、译文或全部遮挡Control the original, translation, or all masks
  • ALT + Z — 切换当前或上次遮挡Switch the current or previous mask
  • ESC — 退出当前编辑，或隐藏遮挡Exit the current edit action, or hide masks
系统级快捷键会在其他应用位于前台时继续工作。若目标应用以管理员身份运行，请查看下方的权限说明。Global shortcuts continue to work while another app is in front. If the target app runs as administrator, see the privilege note below.

一块或两块遮挡One mask or two

单语字幕只需要一块遮挡。双语字幕可以建立上下两块，分别设为原文和译文，再通过快捷键单独控制或一起切换。两块遮挡支持合并、拆分、复制、删除、移动、缩放、居中与铺满宽度。A single subtitle line needs one mask. For bilingual subtitles, create upper and lower masks, assign original and translation roles, then control them separately or together. Two masks can be merged, split, duplicated, deleted, moved, resized, centered, or expanded to full width.

新增第二块遮挡时，它会继承第一块的遮挡或透明状态；合并时，上方遮挡会对齐下方遮挡的宽度，尽量贴合字幕所在的位置。A newly added second mask inherits the first mask's active or transparent state. When merging, the upper mask aligns to the lower mask's width so the result follows the subtitle position.

材质与颜色Materials and color

你可以在经典黑、透明毛玻璃和深色毛玻璃之间切换。颜色主题包含 18 套用于区分原文与译文的双色搭配，以及 14 套让两者保持同色的统一色调，共 32 套；其中包含深岩灰、浅雾灰与多组低饱和色。首次使用默认为透明毛玻璃。Choose between classic black, clear frosted glass, and dark frosted glass. The 32 color themes include 18 two-color palettes that distinguish original and translated subtitles, plus 14 unified tones that keep both the same color—including deep graphite, pale mist gray, and several muted hues. Clear frosted glass is the initial default.

拖动或调整时，遮挡会暂时进入便于编辑的显示方式，完成后恢复所选材质。单击可见遮挡会将它变为透明；透明状态默认穿透鼠标。开启“鼠标单击恢复遮挡”后，再次单击同一区域即可恢复。While you move or resize a mask, it temporarily uses an edit-friendly appearance and returns to the selected material when you finish. Clicking a visible mask makes it transparent; transparent masks pass pointer input through by default. Enable Click to Restore Mask if you want the next click in the same area to restore it.

托盘与开机启动Tray controls and startup

沐幕主要驻留在 Windows 托盘。托盘菜单可以新建遮挡、隐藏或显示全部、调整个性化与语言，并控制是否开机启动。浅色与深色系统会使用对应的托盘图标。Muvail primarily lives in the Windows tray. Its menu can create masks, hide or show all masks, change personalization and language, and control launch at startup. The tray icon adapts to light and dark Windows themes.

遇到问题时If something does not respond

播放器以管理员身份运行The player is running as administrator

如果视频应用使用管理员权限，而沐幕使用普通权限，Windows 可能阻止鼠标与方向键操作。退出视频应用的管理员模式，或让视频应用与沐幕使用相同权限级别。If the video app is elevated while Muvail is not, Windows may block mouse and arrow-key input. Leave administrator mode in the video app, or run both apps at the same privilege level.

虚拟机中的毛玻璃变成色块Acrylic becomes a solid block in a virtual machine

虚拟显卡与桌面合成器可能无法稳定提供 Windows 毛玻璃效果。沐幕会在检测到恢复、解锁或显示变化后尝试重建效果，并在虚拟机中使用安全材质作为后备。原生 Windows 仍可能因显卡、驱动或系统状态而存在差异。Virtual graphics and desktop composition may not provide stable Windows acrylic effects. Muvail attempts to rebuild the effect after resume, unlock, or display changes and uses a safety material in virtual machines when needed. Native Windows behavior can still vary with hardware, drivers, and system state.

找不到托盘图标The tray icon is not visible

先展开任务栏右侧的隐藏图标区域。如果沐幕没有运行，可从开始菜单或桌面快捷方式重新打开。First expand the hidden-icons area at the right of the taskbar. If Muvail is not running, launch it again from the Start menu or desktop shortcut.
