On Air Overview
Tweenly On Air is the live control interface for playing out graphics created in the Tweenly Editor. It allows operators to select graphics, edit text and image fields in real time, and control playback across one or more broadcast sessions.
On Air is a separate web application accessible at your On Air instance URL. It requires a Tweenly account.
Interface layout
The On Air interface consists of three main areas:
- Left Panel (Graphics Sidebar) — Browse and select available graphics.
- Top Right (Preview Frames) — Live preview of selected graphics.
- Bottom Right (Sessions) — Active broadcast sessions with standby and live graphics.
Graphics sidebar
The left panel displays all graphics available for playout.
Each graphic card shows:
- Thumbnail preview
- Name and company
- Last updated date and author
- File size
- Final badge (if marked as final in the Editor)
Filtering by company
Use the dropdown at the top of the sidebar to filter graphics by company, or select ALL to see everything.
Selecting a graphic
Drag a graphic from the sidebar into a session’s standby slot to prepare it for playout.
Sessions
A session represents an active broadcast output — for example, a specific channel or playout instance. The session list is loaded from the backend. Each session appears as an expandable accordion in the bottom-right area.
Each session has two columns:
| Column | Purpose |
|---|---|
| Standby | The graphic is loaded and ready. You can edit its fields before going live. |
| Live | The graphic is currently on air. |
Playback controls
Control the playback of the active graphic in a session:
| Command | Action |
|---|---|
| IN | Send the standby graphic live. It moves from the standby column to the live column. |
| OUT | Remove the graphic from live. |
| NEXT | Advance the animation to the next label or section. |
| OUTRO | Jump to the outro marker and play the outro animation. |
Editing fields in real time
You can edit text and image fields directly in On Air while the graphic is in standby. Once a graphic is live, its fields cannot be edited — send a new version via standby instead.
Text fields
- Edit any field marked as isTextEditable in the Editor.
- Type a new value directly in the field.
- Changes are applied instantly in the preview.
Image fields
- Edit any field marked as isImageEditable in the Editor.
- Click the field to open the asset picker dialog and choose an image from the workspace assets.
- Changes are applied instantly in the preview.
Preview
The top-right area shows a live preview of the selected graphic, rendered in an iframe at the correct aspect ratio.
- The preview updates in real time as you edit fields.
- Playback controls (Play, Pause, Replay, timeline scrubbing) are available for testing animation before going live.
Player mode
On Air can also run in Player Mode — a standalone view for displaying a single graphic.
Access it by adding a graphic ID to the URL: /?graphicId=<id>
In Player Mode:
- Only one graphic is displayed.
- A playback slider and field editors are available.
- A fake data generator can insert random text with a configurable word count range (useful for testing layout limits).
- No session management — intended for embedding or standalone preview.
Workflow summary
A typical On Air workflow:
- Create and export graphics in the Tweenly Editor (mark fields as editable).
- Open On Air and log in.
- Filter graphics by company if needed.
- Drag a graphic into a session’s standby slot.
- Edit text and image fields as needed.
- Preview the graphic to verify appearance.
- Send IN to go live.
- Use NEXT or OUTRO to advance or end the graphic.
- Send OUT to remove from live.
