Up to three cameras at once
最多三颗镜头同时录
Choose from the wide, ultra wide, telephoto and front cameras, then press record once. Each camera writes its own file, and every file starts on the same frame, so the angles line up in your editor without syncing.
从广角、超广角、长焦和前置里挑出要用的，按一次录制。每颗镜头各存一个文件，都从同一帧开始，放进剪辑软件时已经是对齐的。
Exposure is set per camera
每颗镜头单独曝光
Shutter, ISO, focus and exposure compensation are separate for each camera. Go fully manual, or lock just the shutter or just the ISO and let the other one follow the light. Shutter can also be shown as an angle, up to 360°.
快门、ISO、对焦和曝光补偿，每颗镜头分开设。可以全手动，也可以只锁快门或只锁 ISO，另一项跟着光线自动走。快门也能按角度显示，最大 360°。
White balance is the exception. The back cameras share one setting, so the colour matches when you cut between them.
白平衡是例外。后置镜头共用一组设置，剪辑时在机位之间切换，颜色是一致的。
Scopes stay on while you record
录制时示波器照常开着
Waveform, histogram, zebras, false colour and focus peaking. When you shoot Log, you can monitor through Apple’s Rec.709 LUT while the file stays in Log. The other cameras keep running in small windows at the side of the frame.
波形图、直方图、斑马纹、伪色和峰值对焦都有。拍 Log 时可以套 Apple 的 Rec.709 预览 LUT，只改变屏幕上看到的画面，文件仍然是 Log。其他机位在画面一侧的小窗里实时显示。

Questions
常见问题
Which iPhones can run it?哪些 iPhone 能用？
Any iPhone XS or later on iOS 17 or later. How many cameras can record together, and whether ProRes, Log or high frame rates are available, depends on the model.
iPhone XS 及以后的机型，系统需要 iOS 17 或更高版本。能同时开几颗镜头，能不能录 ProRes、Log 和高帧率，要看具体机型。
Does it cost anything?要花钱吗？
It’s free to download and every feature works. Without a purchase, each take stops after 15 seconds. A monthly or yearly subscription, or a one-time purchase, removes the limit.
免费下载，所有功能都能用，只是没购买时每段最多录 15 秒。按月或按年订阅，或者一次买断，就没有这个限制了。
Where do the clips go?视频存在哪里？
You choose in the storage menu: Photos, Plural’s folder in the Files app, or an external drive. Clips recorded from the Lock Screen always go to Photos.
在存储菜单里选：照片图库、文件 App 里 Plural 的文件夹，或者外接硬盘。从锁屏录的视频都存进照片。
What if I leave the app mid-take?录到一半切出 App 会怎样？
Recording stops and the take is saved straight away. iOS doesn’t let the camera keep recording in the background.
录制马上停止，已经录下的部分会保存好。iOS 不允许相机在后台继续录像。
