Link Groups

A Link Group ties widgets together so that operating any one of them broadcasts the same action to the others in real time, as you make the adjustment. It's the live counterpart to Macros: linking mirrors changes as they happen, while a macro recalls a saved snapshot.

The most common use is controlling several cameras as one: put each camera's Shutter widget in the same group, and adjusting one shutter moves them all together.

What can be linked​

Linkable widgets are the ones that emit a camera-state change:

  • Exposure: ND Filter (and ND +/−/Clear), Exposure Index (and EI +/−), and Shutter (all variants: main, +/−, Wheel, Manual, Presets).
  • White Balance: sliders, manual entry, +/− steps, pickers, presets, and tint controls.
  • Record.

Status, playback, and macro widgets are not linkable.

How broadcasting works​

When you operate a widget in a group, its action is sent to every peer widget in the same group:

  • Relative controls (e.g. ND +, Shutter −, EI step) broadcast a step. Each peer applies that step from its own current value.
  • Absolute controls (e.g. White Balance set, a shutter value typed in Manual) broadcast the target value. Each peer is driven to that value.
  • If several widgets in a group point at the same camera, that camera receives the action only once.

Managing groups​

Go to Settings → Link Groups to:

  • Add a group (it gets a default name like "Group 2").
  • Rename a group and assign it a color (the color tints the chain badge on linked widgets so you can see group membership at a glance).
  • Delete a group (its member widgets become unlinked).

Adding a widget to a group​

Open a widget's settings (via the gear icon in edit mode, long-press on iPad, or right-click on Mac), then use the Link submenu to pick a group from the list. You can also create a group directly from that menu with New Group….

note

The Link submenu only appears for linkable widgets.

Removing a widget from a group​

Every linked widget shows a chain badge Link badge in its bottom-right corner, tinted with its group's color. Tap the chain badge and choose Unlinked from the group list to remove the widget from its group.

The same Link submenu is also available from the widget's context menu (long-press on iPad, right-click on Mac) and from the gear menu in edit mode — choosing Unlinked in any of them unlinks the widget.

note

Deleting a group from Settings → Link Groups unlinks all of its member widgets at once.

Linking from Companion​

You can also drive linked control from Bitfocus Companion by targeting multiple cameras in a single action. See Linking in Companion.
