UE Sequencer and Cinematics
Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".
Sequencer spans three runtime modules plus a plugin. MovieScene holds the data model and the player base class, MovieSceneTracks holds the concrete track and section types, LevelSequence holds the asset, actor, player and director, and CinematicCamera holds the cine camera and camera rigs. Offline rendering lives in the Movie Render Queue plugin (MovieRenderPipelineCore for runtime, MovieRenderPipelineEditor for the editor queue UI); it is disabled by default and must be enabled in the .uproject.
Context
Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.
Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.

Runtime vs Editor
Authoring a sequence is an editor operation. Shipping game code plays and re-binds sequences; it does not build them.
| Task | API | Availability |
|---|---|---|
| Play, stop, seek, set play rate | UMovieSceneSequencePlayer | Runtime |
| Override which actors a binding resolves to | ALevelSequenceActor::SetBinding* | Runtime |
| Read tracks, bindings, frame rates | UMovieScene getters, UMovieSceneSequence::GetMovieScene | Runtime |
| Call C++ from the timeline | ULevelSequenceDirector subclass | Runtime |
| Queue and run a render | UMoviePipelineQueueEngineSubsystem (UEngineSubsystem) | Runtime |
| Add actors, cameras, spawnables to a sequence | ULevelSequenceEditorSubsystem (UEditorSubsystem) | Editor only |
| Scripted track/section creation and keying | UMovieSceneSequenceExtensions (Runtime module of the Beta SequencerScripting plugin) | Editor scripting — mutates assets |
| Register a custom track editor | ISequencerModule::RegisterTrackEditor | Editor only |
| Drive the Movie Render Queue window | UMoviePipelineQueueSubsystem (UEditorSubsystem) | Editor only |
UMovieScene::AddTrack and UMovieSceneSubTrack::AddSequence do compile into runtime builds, but they mutate the sequence asset. Call them only from editor tooling or commandlets — a cooked ULevelSequence must not be edited in a shipped game.
Playing a Level Sequence
From a placed ALevelSequenceActor
#include "LevelSequenceActor.h"
// LevelSequenceActor.h:153 — UFUNCTION(BlueprintGetter) ULevelSequencePlayer* GetSequencePlayer() const;
if (ULevelSequencePlayer* Player = SeqActor->GetSequencePlayer())
{
Player->Play();
}
Useful ALevelSequenceActor members: PlaybackSettings, LevelSequenceAsset, BindingOverrides, DefaultInstanceData, bOverrideInstanceData, bReplicatePlayback, GetSequence(), SetSequence(), SetReplicatePlayback(). Auto-play is PlaybackSettings.bAutoPlay; the actor's own bAutoPlay field no longer exists. AReplicatedLevelSequenceActor is a subclass that is always net-relevant.
Spawning a player at runtime
#include "LevelSequencePlayer.h"
#include "MovieSceneSequencePlaybackSettings.h"
// LevelSequencePlayer.h:106
// static ULevelSequencePlayer* CreateLevelSequencePlayer(
// UObject* WorldContextObject, ULevelSequence* LevelSequence,
// FMovieSceneSequencePlaybackSettings Settings, ALevelSequenceActor*& OutActor);
FMovieSceneSequencePlaybackSettings Settings;
Settings.bAutoPlay = false;
Settings.PlayRate = 1.0f;
Settings.StartTime = 0.0f; // seconds into the playback range
Settings.LoopCount.Value = 0; // 0 = once, -1 = infinite, N = N extra loops
Settings.bDisableMovementInput = true;
Settings.bDisableLookAtInput = true;
Settings.bHidePlayer = false;
Settings.bHideHud = true;
Settings.bDisableCameraCuts = false;
Settings.bPauseAtEnd = false;
Settings.bDynamicWeighting = false; // set true (or enable it on the asset) before using SetWeight() — MovieSceneSequencePlayer.h:278
Settings.FinishCompletionStateOverride = EMovieSceneCompletionModeOverride::ForceRestoreState;
ALevelSequenceActor* OutActor = nullptr;
ULevelSequencePlayer* Player = ULevelSequencePlayer::CreateLevelSequencePlayer(
this, CutsceneAsset, Settings, OutActor);
ActiveSequenceActor = OutActor; // UPROPERTY member — otherwise both are collected
ActivePlayer = Player; // UPROPERTY member
// Remaining fields: bRandomStartTime, TickInterval, bInheritTickIntervalFromOwner
Playback control
Player->Play();
Player->PlayReverse();
Player->PlayLooping(-1); // -1 = infinite
Player->ChangePlaybackDirection();
Player->Pause();
Player->Scrub();
Player->Stop(); // resets the cursor and fires OnStop
Player->StopAtCurrentTime();
Player->GoToEndAndStop();
Player->SetPlayRate(0.5f);
Player->SetFrameRange(0, 60); // (StartFrame, Duration) in display-rate frames
Player->SetTimeRange(0.0f, 2.5f); // (StartTime, Duration) in seconds
// Seek without firing the events in between
Player->SetPlaybackPosition(
FMovieSceneSequencePlaybackParams(FFrameTime(120), EUpdatePositionMethod::Jump));
// Advance to a frame, firing every event along the way
Player->PlayTo(
FMovieSceneSequencePlaybackParams(FFrameTime(240), EUpdatePositionMethod::Play),
FMovieSceneSequencePlayToParams());
// Seconds instead of frames: FMovieSceneSequencePlaybackParams(2.5f, EUpdatePositionMethod::Jump)
const bool bPlaying = Player->IsPlaying();
const FQualifiedFrameTime Now = Player->GetCurrentTime();
const FQualifiedFrameTime Dur = Player->GetDuration();
const FFrameRate Rate = Player->GetFrameRate();
EUpdatePositionMethod is Play, Jump or Scrub. FMovieSceneSequencePlaybackParams has constructors taking FFrameTime, float seconds, an FString marked-frame name, or an FTimecode.
Delegates
// UPROPERTY(BlueprintAssignable) FOnMovieSceneSequencePlayerEvent — dynamic, no parameters
Player->OnPlay.AddDynamic(this, &AMyCutsceneManager::HandleSequencePlay);
Player->OnStop.AddDynamic(this, &AMyCutsceneManager::HandleSequenceStop);
Player->OnFinished.AddDynamic(this, &AMyCutsceneManager::HandleSequenceFinished);
Player->OnPause.AddDynamic(this, &AMyCutsceneManager::HandleSequencePause);
Player->OnNativeFinished.BindUObject(this, &AMyCutsceneManager::HandleNativeFinished); // native

// FOnLevelSequencePlayerCameraCutEvent, UCameraComponent*, CameraComponent)
Player->OnCameraCut.AddDynamic(this, &AMyCutsceneManager::HandleCameraCut);
OnFinished fires only when playback ends naturally (a natural end fires OnStop too); an explicit Stop() fires only OnStop. Bind before Play().
Binding Actors at Runtime
A possessable resolves to an actor that already exists in the level. A spawnable is created and destroyed by the sequence itself. Possessables outlive the sequence; spawnables do not. Runtime overrides apply to possessables.
Tag the object binding in the Sequencer editor (right-click the binding, then Tags), and override by tag from C++ — tags survive re-binding, GUIDs do not.
#include "LevelSequenceActor.h"
#include "MovieSceneObjectBindingID.h"
// LevelSequenceActor.h:178-253
SeqActor->SetBindingByTag(FName("Hero"), TArray<AActor*>{ HeroActor },
/*bAllowBindingsFromAsset=*/ false);
SeqActor->AddBindingByTag(FName("Crowd"), ExtraActor, /*bAllowBindingsFromAsset=*/ true);
SeqActor->RemoveBindingByTag(FName("Crowd"), ExtraActor);
// GUID form — expose the ID so a designer can pick the binding in the details panel:
// UPROPERTY(EditAnywhere, Category = "Cinematics") FMovieSceneObjectBindingID HeroBindingID;
SeqActor->SetBinding(HeroBindingID, TArray<AActor*>{ HeroActor }, false);
SeqActor->AddBinding(HeroBindingID, HeroActor, false);
SeqActor->RemoveBinding(HeroBindingID, HeroActor);
SeqActor->ResetBinding(HeroBindingID); // back to whatever the asset says
SeqActor->ResetBindings(); // clear every override
const FMovieSceneObjectBindingID Found = SeqActor->FindNamedBinding(FName("Hero"));
const TArray<FMovieSceneObjectBindingID>& All = SeqActor->FindNamedBindings(FName("Crowd"));
// What is actually bound right now
TArray<UObject*> Bound = Player->GetBoundObjects(HeroBindingID);
FMovieSceneObjectBindingID keeps its guid and sequence id private. Read them with GetGuid(), GetRelativeSequenceID() and IsFixedBinding(); move an ID across a sub-sequence hierarchy with ResolveToFixed(), then ConvertToRelative() on the resulting UE::MovieScene::FFixedObjectBindingID (ConvertToRelative is not a member of FMovieSceneObjectBindingID, MovieSceneObjectBindingID.h:113-160,341). Never assign the fields directly.
Relocating a whole sequence
ALevelSequenceActor implements IMovieScenePlaybackClient::GetInstanceData. Set bOverrideInstanceData and supply a UDefaultLevelSequenceInstanceData to offset every absolute transform section, so one authored cutscene can play anywhere in the world.
#include "DefaultLevelSequenceInstanceData.h"
UDefaultLevelSequenceInstanceData* Data =
NewObject<UDefaultLevelSequenceInstanceData>(SeqActor);
Data->TransformOriginActor = StageMarkerActor; // or leave null and set TransformOrigin
SeqActor->DefaultInstanceData = Data;
SeqActor->bOverrideInstanceData = true;

An event key does not call a loose global function. FMovieSceneEvent stores a compiled UFunction pointer, and the

## Playing a Level Sequence
### From a placed ALevelSequenceActor
```cpp
#include "LevelSequenceActor.h"
// LevelSequenceActor.h:153 — UFUNCTION(BlueprintGetter) ULevelSequencePlayer* GetSequencePlayer() const;
if (ULevelSequencePlayer* Player = SeqActor->GetSequencePlayer())
{
Player->Play();
}
```
Useful `ALevelSequenceActor` members: `PlaybackSettings`, `LevelSequenceAsset`, `BindingOverrides`, `DefaultInstanceData`, `bOverrideInstanceData`, `bReplicatePlayback`, `GetSequence()`, `SetSequence()`, `SetReplicatePlayback()`. Auto-play is `PlaybackSettings.bAutoPlay`; the actor's own `bAutoPlay` field no longer exists. `AReplicatedLevelSequenceActor` is a subclass that is always net-relevant.
### Spawning a player at runtime
```cpp
#include "LevelSequencePlayer.h"
#include "MovieSceneSequencePlaybackSettings.h"
// LevelSequencePlayer.h:106
// static ULevelSequencePlayer* CreateLevelSequencePlayer(
// UObject* WorldContextObject, ULevelSequence* LevelSequence,
// FMovieSceneSequencePlaybackSettings Settings, ALevelSequenceActor*& OutActor);
FMovieSceneSequencePlaybackSettings Settings;
Settings.bAutoPlay = false;
Settings.PlayRate = 1.0f;
Settings.StartTime = 0.0f; // seconds into the playback range
Settings.LoopCount.Value = 0; // 0 = once, -1 = infinite, N = N extra loops
Settings.bDisableMovementInput = true;
Settings.bDisableLookAtInput = true;
Settings.bHidePlayer = false;
Settings.bHideHud = true;
Settings.bDisableCameraCuts = false;
Settings.bPauseAtEnd = false;
Settings.bDynamicWeighting = false; // set true (or enable it on the asset) before using SetWeight() — MovieSceneSequencePlayer.h:278
Settings.FinishCompletionStateOverride = EMovieSceneCompletionModeOverride::ForceRestoreState;
ALevelSequenceActor* OutActor = nullptr;
ULevelSequencePlayer* Player = ULevelSequencePlayer::CreateLevelSequencePlayer(
this, CutsceneAsset, Settings, OutActor);
ActiveSequenceActor = OutActor; // UPROPERTY member — otherwise both are collected
ActivePlayer = Player; // UPROPERTY member
// Remaining fields: bRandomStartTime, TickInterval, bInheritTickIntervalFromOwner
```
### Playback control
```cpp
Player->Play();
Player->PlayReverse();
Player->PlayLooping(-1); // -1 = infinite
Player->ChangePlaybackDirection();
Player->Pause();
Player->Scrub();
Player->Stop(); // resets the cursor and fires OnStop
Player->StopAtCurrentTime();
Player->GoToEndAndStop();
Player->SetPlayRate(0.5f);
Player->SetFrameRange(0, 60); // (StartFrame, Duration) in display-rate frames
Player->SetTimeRange(0.0f, 2.5f); // (StartTime, Duration) in seconds
// Seek without firing the events in between
Player->SetPlaybackPosition(
FMovieSceneSequencePlaybackParams(FFrameTime(120), EUpdatePositionMethod::Jump));
// Advance to a frame, firing every event along the way
Player->PlayTo(
FMovieSceneSequencePlaybackParams(FFrameTime(240), EUpdatePositionMethod::Play),
FMovieSceneSequencePlayToParams());
// Seconds instead of frames: FMovieSceneSequencePlaybackParams(2.5f, EUpdatePositionMethod::Jump)
const bool bPlaying = Player->IsPlaying();
const FQualifiedFrameTime Now = Player->GetCurrentTime();
const FQualifiedFrameTime Dur = Player->GetDuration();
const FFrameRate Rate = Player->GetFrameRate();
```
`EUpdatePositionMethod` is `Play`, `Jump` or `Scrub`. `FMovieSceneSequencePlaybackParams` has constructors taking `FFrameTime`, `float` seconds, an `FString` marked-frame name, or an `FTimecode`.
### Delegates
```cpp
// UPROPERTY(BlueprintAssignable) FOnMovieSceneSequencePlayerEvent — dynamic, no parameters
Player->OnPlay.AddDynamic(this, &AMyCutsceneManager::HandleSequencePlay);
Player->OnStop.AddDynamic(this, &AMyCutsceneManager::HandleSequenceStop);
Player->OnFinished.AddDynamic(this, &AMyCutsceneManager::HandleSequenceFinished);
Player->OnPause.AddDynamic(this, &AMyCutsceneManager::HandleSequencePause);
Player->OnNativeFinished.BindUObject(this, &AMyCutsceneManager::HandleNativeFinished); // native
// LevelSequencePlayer.h:27 — DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(
// FOnLevelSequencePlayerCameraCutEvent, UCameraComponent*, CameraComponent)
Player->OnCameraCut.AddDynamic(this, &AMyCutsceneManager::HandleCameraCut);
```
`OnFinished` fires only when playback ends naturally (a natural end fires `OnStop` too); an explicit `Stop()` fires only `OnStop`. Bind before `Play()`.
## Binding Actors at Runtime
A **possessable** resolves to an actor that already exists in the level. A **spawnable** is created and destroyed by the sequence itself. Possessables outlive the sequence; spawnables do not. Runtime overrides apply to possessables.
Tag the object binding in the Sequencer editor (right-click the binding, then Tags), and override by tag from C++ — tags survive re-binding, GUIDs do not.
```cpp
#include "LevelSequenceActor.h"
#include "MovieSceneObjectBindingID.h"
// LevelSequenceActor.h:178-253
SeqActor->SetBindingByTag(FName("Hero"), TArray<AActor*>{ HeroActor },
/*bAllowBindingsFromAsset=*/ false);
SeqActor->AddBindingByTag(FName("Crowd"), ExtraActor, /*bAllowBindingsFromAsset=*/ true);
SeqActor->RemoveBindingByTag(FName("Crowd"), ExtraActor);
// GUID form — expose the ID so a designer can pick the binding in the details panel:
// UPROPERTY(EditAnywhere, Category = "Cinematics") FMovieSceneObjectBindingID HeroBindingID;
SeqActor->SetBinding(HeroBindingID, TArray<AActor*>{ HeroActor }, false);
SeqActor->AddBinding(HeroBindingID, HeroActor, false);
SeqActor->RemoveBinding(HeroBindingID, HeroActor);
SeqActor->ResetBinding(HeroBindingID); // back to whatever the asset says
SeqActor->ResetBindings(); // clear every override
const FMovieSceneObjectBindingID Found = SeqActor->FindNamedBinding(FName("Hero"));
const TArray<FMovieSceneObjectBindingID>& All = SeqActor->FindNamedBindings(FName("Crowd"));
// What is actually bound right now
TArray<UObject*> Bound = Player->GetBoundObjects(HeroBindingID);
```
`FMovieSceneObjectBindingID` keeps its guid and sequence id private. Read them with `GetGuid()`, `GetRelativeSequenceID()` and `IsFixedBinding()`; move an ID across a sub-sequence hierarchy with `ResolveToFixed()`, then `ConvertToRelative()` on the resulting `UE::MovieScene::FFixedObjectBindingID` (`ConvertToRelative` is not a member of `FMovieSceneObjectBindingID`, `MovieSceneObjectBindingID.h:113-160,341`). Never assign the fields directly.
### Relocating a whole sequence
`ALevelSequenceActor` implements `IMovieScenePlaybackClient::GetInstanceData`. Set `bOverrideInstanceData` and supply a `UDefaultLevelSequenceInstanceData` to offset every absolute transform section, so one authored cutscene can play anywhere in the world.
```cpp
#include "DefaultLevelSequenceInstanceData.h"
UDefaultLevelSequenceInstanceData* Data =
NewObject<UDefaultLevelSequenceInstanceData>(SeqActor);
Data->TransformOriginActor = StageMarkerActor; // or leave null and set TransformOrigin
SeqActor->DefaultInstanceData = Data;
SeqActor->bOverrideInstanceData = true;
```
