Rehearse and check
▶ Play the show rehearses a rundown with real timing. It starts with every template of the bottom lane in turn and the other lanes going on and off; each step uses the transition that would really play and holds briefly on air. Select a step to jump there, × to remove it, or add a step for any lane (a template, or Take it off). Reset rundown restores the starting rundown.
Checks
| Check | Means | Fix |
|---|---|---|
| Lane covers lane | Two lanes overlap when on air together and nothing makes room. | Make room… opens Together on air. |
| Element doesn't match its templates | A stored value differs from where a template places the element. | Use template values, or Keep these values. |
| Content runs off the frame | Part of a template reaches past the frame edge while on air. | Adjust the template. |
| Element isn't in every template | A template doesn't place the element; it uses its Off position there. | Place it in that template. |
| A moment has no timing | Two timings claim a moment, or a timing is missing. | Open the moment and pick a style. |
Every change saves at once as its own undoable step. If an older unapplied draft exists, a banner
offers Apply it or Discard it. Turn off playout… at the end of the side column removes
lanes and timings but keeps templates and components; it can be undone. Save the template set to
write the playout to .ogs.
Behavior preview
A moment's ▶ Preview uses the existing Preview & Export viewport. It uses the current definition and unsaved template edits, including the affected graphics and elements that stay on screen. The compact data fields control the selected graphic. Fullscreen shows the same combined output and starts with its data panel hidden. There is no additional preview-mode selector. Selecting another template restores its ordinary lifecycle preview. Behavior preview is isolated from MCP live output and does not export a package.
