Manually add recordings

You can also add recordings from other sources, like your phone.
Simply name the file webcam followed by any number, like 10, followed by one of the supported file extensions: .mp4, .webm, .mkv or .mov.

The order your recordings appear in your video is based on the number suffix.
Here is a way you could structure your recordings:

txt
public
└── my-video
    ├── webcam10.mp4
    ├── display10.mp4
    ├── webcam20.mp4
    └── webcam30.mp4

txt
public
└── my-video
    ├── webcam10.mp4
    ├── display10.mp4
    ├── webcam20.mp4
    └── webcam30.mp4

If there is only a webcam recording with said number, the webcam will be fullscreen.

A display recording will only get picked up if there is also a webcam recording.
The webcam will be miniaturized in this case.

If you only have recorded a display, give it a webcam prefix nonetheless for it to get picked up.
