Sequencer Overview

The Sequencer integration lets you control OBS directly from Unreal’s Level Sequencer with frame-accurate timing. Switch scenes, fade audio, animate source transforms, sync media, and start/stop recording, all keyed against your timeline.

Adding an OBS Track

Open any Level Sequence.
Click +Track → OBS Track.
Click + on the track to add action sections.
Configure each section’s action in the Details panel.
Play the sequence and OBS responds!

Track Header

The OBS Track header shows:

Connection indicator: green dot (connected) or red dot (disconnected).
+ button: add new action sections.

Track Settings

Configure when actions fire via track properties:

Setting	Default	Description
`bFireActionsWhenForwards`	true	Fire during normal playback
`bFireActionsWhenBackwards`	false	Fire when playing in reverse
`bFireActionsWhenScrubbing`	false	Fire when dragging the playhead (use with caution!)
`bMuted`	false	Disable all sections without deleting
`bRestoreStateOnTearDown`	true	Restore OBS state when sequence stops

The Four Track Families

The plugin provides four track paradigms, each suited to a different kind of OBS control:

Family	Behavior	Use Case
Event Trigger	Actions fire when the playhead crosses section start	Discrete commands (StartRecord, SwitchScene, SaveReplay)
Keyframeable	Values interpolated via curve editor keyframes	Smooth animations (volume fades, transform motion, color shifts)
Continuous State	State applied while the playhead is inside a section	Temporary overrides (mute during section, force visibility, hold transition)
Media Sync	OBS media cursor follows the Sequencer timeline	Synchronized video playback, scrubbing seeks media

See tracks.md for full details on each family and actions.md for the complete Event Trigger action reference.

All OBS tracks are organized under a single “OBS” submenu:
