Sequencer & cinematics

Sequencer is Unreal's non-linear timeline editor. A Level Sequence (ULevelSequence) binds actors and animates their properties via tracks; you play it at runtime through a ULevelSequencePlayer for cutscenes or scripted moments, and feed gameplay events back through event tracks or the OnFinished delegate.

When to use this skill

• Triggering a cutscene or scripted in-game beat from C++ and reacting when it ends.
• Overriding which actors a sequence controls at runtime (dynamic/spawned characters).
• Animating a film-style camera (focal length, aperture, depth of field) via Cine Camera.
• Firing gameplay functions at exact timeline positions (event tracks / Director blueprint).
• Using Movie Render Queue for offline high-quality output from a sequence asset.
