Linking elements to integrations
Connect rundown elements to Helmo Graphics or external platforms so they send commands automatically when they execute.
For an element to actually trigger a command during your show, it needs to be linked to an integration.
What is an integration link?
An integration link connects a rundown element to a specific resource in an external system. For example, linking a GFX element to a lower third overlay in Viz Flowics, or linking a LIVE element to an OBS scene switch.
How to link an element
- Open an element (click to expand).
- Select an Integration from the dropdown. This lists all integrations configured in your workspace.
- Select the Action: the specific command to send (IN, OUT, scene switch, mute, etc.).
- Configure any parameters the action requires (overlay ID, scene name, source name, etc.).
- The element is now linked. When it executes during a live show, it sends the command automatically.
Integration types and what they control
| Integration | Category | What the element controls |
|---|---|---|
| Viz Flowics | Graphics | Overlay layers: IN, OUT, PATCH, field updates, timers, lists |
| Singular.live | Graphics | Compositions: IN, OUT |
| Helmo Graphics | Graphics (Native) | Subcompositions: IN, OUT, TOGGLE, PATCH, field updates |
| OBS Studio | Broadcast | Scenes, sources, audio mute/volume, filters, recording, streaming, virtual camera, replay buffer |
| vMix | Broadcast | Overlays, transitions, text/image updates, recording, streaming, snapshot |
| CasparCG | Broadcast | PLAY, STOP, LOAD, LOADBG, CLEAR, CG ADD/UPDATE/STOP/NEXT/CLEAR/PLAY |
| MeldStudio | Broadcast | Scenes, layers, effects, audio, streaming, recording, replay, widgets |
| YouTube Live | Streaming | Start/stop broadcast, stream status |
| Twitch | Streaming | Stream controls, channel updates |
| Kick | Streaming | Stream controls |
| Generic HTTP | Data / Custom | Any REST API endpoint with variable substitution |
| Action Sequence | Automation | Trigger a pre-built multi-step Action Sequence |
Field values (Graphics elements)
For GFX elements linked to Viz Flowics or Helmo Graphics, you can set field values directly on the element. These values are sent as PATCH/UPDATE commands when the element executes, updating text, numbers, or images on the graphic without a separate button press.
OBS Audio & Filter actions in Rundown
When linking an element to OBS, you can select audio and filter actions in addition to scene/source control:
- Mute / Unmute / Toggle Mute: control a specific audio input by name
- Set Volume: set volume level (0-100%) for any input
- Enable / Disable / Toggle Filter: control any filter on any source
- Set Filter Settings: update filter parameters (e.g. chroma key color, compressor threshold)
This means you can automate a complete production moment from a single rundown element: switch scene, bring up a graphic, and mute a mic, all at once.
Tips
- Make sure your integrations are configured in Connect before linking elements.
- Integration names in the dropdown match what you named them in the Integrations Hub.
- Scene, source, and filter names must match exactly what's configured in OBS (case-sensitive).
- For Viz Flowics and Singular elements, you can preview the linked graphic using the preview icon on the element row.
- If no integrations appear in the dropdown, check that your workspace has at least one active integration in Connect.
