Multiview tiles a bundle of streams into one picture, with labels, for monitoring.
What it does#
The input carries 1 to 8 streams, joined with Combine streams. Columns sets the grid, Gap the space between tiles and Labels adds the stream numbers.
When to use it#
Use it to watch several sources at once, for example before a Switcher.
Ports#
| Port | Direction | Signal | Lanes |
|---|---|---|---|
video | Input | Video | Inferred from the cable |
video | Output | Video | 1 |
Parameters#
| Parameter | Label | Range | Default | Unit | Scale | Notes |
|---|---|---|---|---|---|---|
columns | Columns | 1 to 4 | 2 | linear | Tiles per row. | |
gap | Gap | 0 to 64 | 4 | px | linear | Space between tiles in pixels. |
labels | Labels | 0 to 1 | 1 | linear | Show stream numbers on the tiles. Choices: 0 Hidden, 1 Shown. |
Columns (columns)#
Number of columns in the grid, 1 to 4.
Gap (gap)#
Space between tiles in pixels.
Labels (labels)#
Shows a label on each tile when on.
Tips#
- The output is one stream and can be filtered or recorded like any other.
- Video needs the browser's WebGPU video engine. The Player and exports do not run video yet and report it unavailable. To see a video output, bind a live Screen in the Frame to it.
