Adding a source
- Tap the + button on any empty slot in the source grid — the picker is titled Add Input with the slot number
- Select a source type from the picker
- Configure the source (e.g., select an NDI device, choose a video file, enter text)
- Confirm
Every source panel works the same way: nothing is created until you confirm, and cancelling part-way leaves the slot empty rather than half-configured. If a source fails to start, the slot rolls back to empty and tells you why.
The source begins loading and appears in the slot with a live thumbnail once active.
Taking a closer look
Every source editor has a magnify button in its action row. It opens that source’s live video full-window, with pinch to zoom from 1x and drag to pan — the way to check focus or read a lower third without cutting to it.
The program monitor has the same button, for a full-window look at what’s actually going to air.
Removing a source
- Long-press the source slot in the grid
- Tap Remove Source
The slot becomes empty and available for a new source.
Source states
Each source has a state indicator:
- Idle — Source is configured but not yet active
- Loading — Source is connecting or buffering
- Active — Source is producing frames and ready for use
- Error — Connection failed or source is unavailable
- Paused — Media player is paused
Reordering sources
Long-press and drag a source slot to reorder it in the grid. The slot number affects keyboard shortcuts and OSC addressing (slots are numbered starting from 1).
