1 启动并选择录制模式Launch and pick a capture mode

第一步:先确定要录制什么
Step 1: decide what to capture

启动后,在右侧控制面板「采集」分组中选择录制模式:显示器 Monitor(录制整个屏幕)、窗口 Window(只录制某个窗口)、区域 Region(拖拽框选屏幕的一块区域)。本教程以「显示器」为例。首次启动时会弹出欢迎窗口,点击「阅读教程」即可打开本网页。 On the "Capture" section of the right control panel, pick a mode: Monitor (record the whole screen), Window (record a single window) or Region (drag to select an area of the screen). This guide uses "Monitor". A welcome window appears on first launch — click "Read tutorial" to open this page.

应用主界面:预览卡片 + 右侧控制面板
💡 中央预览卡片实时显示当前采集画面;底部状态栏显示画布分辨率、实时 FPS 与录制计时。The preview card shows the live capture; the status bar shows canvas resolution, live FPS and recording time.

2 窗口模式:选择目标窗口Window mode: pick a target window

第二步:在窗口模式下选择要录制的窗口
Step 2: choose a window to capture

切换到「窗口」模式后,会显示窗口下拉框与刷新按钮。从下拉框选择要录制的窗口,预览画面随即切换为该窗口的内容;列表中找不到目标窗口时,点击刷新按钮重新枚举。 Switching to "Window" mode reveals a window dropdown and a refresh button. Pick the window to capture and the preview switches to its contents; if your target is missing, hit refresh to re-enumerate.

窗口下拉框与刷新按钮
⚠️ 尽量保持目标窗口可见(不要最小化),最小化的窗口可能捕获为空白画面。Keep the target window visible (don't minimize it) — minimized windows may capture as a blank frame.

3 配置音频:系统声音与麦克风Audio: system sound & microphone

第三步:选择录音源并观察音量
Step 3: pick audio sources and watch the levels

在右侧「声音」分组中,勾选「录制系统声音」「录制麦克风」并各自选择音频设备。下方的两条 VU 音量表实时显示电平:绿色区间为正常、黄色偏大、红色接近爆音;白色竖线为峰值保持,右侧 dB 读数精确显示分贝值。每个声道都配有静音开关与音量滑块。 In the "Audio" section, check "record system audio" and "record microphone" and pick a device for each. The two VU meters show live levels: green is normal, yellow is loud, red is near clipping; the white line holds the peak and the dB readout shows the precise level. Each channel has a mute toggle and a volume slider.

声音分组与 VU 音量表
💡 音量表不动说明没有信号——检查设备是否选对、系统音量是否为 0、静音是否被打开。A silent meter means no signal — check the device, the system volume and the mute state.

4 摄像头:开启画中画Camera: enable picture-in-picture

第四步:可选地叠加摄像头画面
Step 4: optionally overlay your camera feed

勾选「启用摄像头」后选择摄像头设备,画面将作为画中画叠加进录制画面。不勾选则完全不会请求摄像头权限。 Check "Enable camera" and pick a device — the feed is overlaid into the recording as picture-in-picture. When unchecked, no camera permission is ever requested.

5 视频与输出设置Video & output settings

第五步:设置分辨率、帧率与保存位置
Step 5: set resolution, FPS and save location

「视频」分组可选择分辨率(1280×720 至 3840×2160)与帧率(24 / 30 / 60 / 120)。「保存」分组设置输出路径(默认 D:\recordings,点「浏览」选择)、文件名(默认 recording)与格式(MP4 / MKV / MOV / FLV / WebM)。 The "Video" section sets the resolution (1280×720 up to 3840×2160) and FPS (24 / 30 / 60 / 120). The "Output" section sets the save path (default D:\recordings, use Browse), the file name (default "recording") and the format (MP4 / MKV / MOV / FLV / WebM).

视频与保存设置
⚠️ 4K 或 60/120 帧会明显增大文件体积并提高 CPU 与 GPU 占用,日常录制 1920×1080 / 30 帧即可。4K or 60/120 FPS greatly increases file size and CPU/GPU load — 1920×1080 @ 30 FPS is plenty for everyday use.

6 开始录制与停止Record and stop

第六步:一键开始,随时停止
Step 6: one click to start, stop anytime

点击右下角的大红色「开始录制」按钮,窗口自动最小化、任务栏图标闪烁提示;预览卡片左上角出现红点计时浮标,状态栏同步显示「● 录制中」与耗时。再次点击同一按钮(或从任务栏回到窗口点击)即停止录制。文件按 文件名-1、-2… 自动去重,不会覆盖旧文件。 Click the big red "Start recording" button — the window minimizes, the taskbar icon flashes, a red-dot timer badge appears on the preview and the status bar shows "● Recording" with the elapsed time. Press the same button again (or restore from the taskbar) to stop. Files are auto-deduplicated as name-1, name-2…, so old recordings are never overwritten.

录制浮标与状态栏
💡 视频保存在「保存」分组设置的输出目录中,停止后打开该目录即可查看。Videos are saved to the output folder set in the Output section — open it to view the result.

7 区域录制Region recording

框选屏幕任意区域进行录制
Record any on-screen area
  1. 选择「区域」模式Select "Region" mode.
  2. 屏幕出现十字光标遮罩,拖拽框选要录制的区域A crosshair overlay appears — drag to select the area.

9 配置与命令行Config & command line

OBS 安装路径与高级启动参数
OBS install path and advanced launch args
  1. 配置文件位于 %APPDATA%\ScreenRecorder\config.json,修改 ObsInstallDir 可指向非默认位置的 OBS 安装目录The config lives at %APPDATA%\ScreenRecorder\config.json; edit ObsInstallDir to point to a non-default OBS install.
  2. 通过 --config-dir <目录> 启动参数可指定其他的配置目录Launch with --config-dir <dir> to use a different config directory.
  3. 启动时传入一个文件路径,将自动填入「文件名」输入框Passing a file path on the command line pre-fills the file name box.
💡 应用基于 libobs(OBS 内核)开发,需要本机安装 OBS Studio(默认 C:\Program Files\obs-studio,或由配置指向)。The app is built on the libobs core and needs OBS Studio installed (default C:\Program Files\obs-studio, or wherever the config points).

❓ 常见问题FAQ

需要安装 OBS 吗?
Do I need OBS installed?

是。应用基于 libobs(OBS 内核)开发,需要本机已安装 OBS Studio。默认读取 C:\Program Files\obs-studio,非默认安装位置请在 config.json 中修改 ObsInstallDir。

Yes — the app is built on libobs and needs OBS Studio installed. It defaults to C:\Program Files\obs-studio; for another location set ObsInstallDir in config.json.

支持哪些分辨率和帧率?
What resolutions and FPS are supported?

分辨率 1280×720 / 1920×1080 / 2560×1440 / 3840×2160,帧率 24 / 30 / 60 / 120;区域模式由选区大小决定。

支持哪些输出格式?
What output formats are supported?

MP4 / MKV / MOV / FLV / WebM。默认 MP4,播放兼容性最好。

MP4 / MKV / MOV / FLV / WebM. MP4 (the default) is the most compatible.

重复录制会覆盖旧文件吗?
Will old recordings be overwritten?

不会。同名文件会自动命名为「文件名-1、-2」…,绝不静默覆盖。

No — duplicates are saved as name-1, name-2… and never silently overwritten.

开始录制后窗口自动最小化了,怎么停止?
The window minimized itself — how do I stop?

录制开始后窗口自动最小化且任务栏图标闪烁提示。点击任务栏图标回到窗口,再按一次红色录制按钮即可停止。

The window auto-minimizes and the taskbar flashes. Click the taskbar icon to restore, then press the red button again.

录制的视频没有声音?
The recording has no audio?

检查「声音」分组:是否勾选了要录制的源、设备是否选对;观察 VU 音量表是否跳动、静音是否被打开、系统音量是否为 0。

Check the Audio section: is the source checked and the device correct? Watch the VU meter — is it moving, is mute on, is the system volume at zero?
