UMovieGraphSequenceDataSource | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/MovieRenderPipelineCore

The UMovieGraphSequenceDataSource allows using a ULevelSequence as the external datasource for the Movie Graph. It will build the range of shots based on the contents of the level sequence (one shot per camera cut found inside the sequence hierarchy, not allowing overlapping Camera Cut sections), and then it will evaluate the level sequence for the given time when rendering.

Functions

Overridden from UMovieGraphDataSourceBase

Name	Remarks	Include Path
virtual void CacheDataPreJob ( const FMovieGraphInitConfig& InInitConfig )	Called when the Movie Graph Pipeline starts before anything has happened, allowing you to cache your datasource before making any modifications to it as a result of rendering.	Graph/MovieGraphSequenceDataSource.h
virtual void CacheHierarchyForShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot )		Graph/MovieGraphSequenceDataSource.h
virtual void ExpandShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot, const int32 InLeftDeltaFrames, const int32 InLeftDeltaFramesUserPoV, const int32 InRightDeltaFrames, const bool bInPrepass )		Graph/MovieGraphSequenceDataSource.h
virtual TArray< UE::MovieGraph::FMinimalCameraInfo > GetCameraInformation ( UMoviePipelineExecutorShot* InShot, bool bIncludeSidecar ) const		Graph/MovieGraphSequenceDataSource.h
virtual FFrameRate GetDisplayRate()	A lower res, human readable Frame Rate. We convert to the Tick Resolution internally. (ie: 24/1)	Graph/MovieGraphSequenceDataSource.h
virtual FFrameRate GetTickResolution()	An internal, high resolution framerate that seeks, etc. will be returned in. (ie: 24,000/1)	Graph/MovieGraphSequenceDataSource.h
virtual void InitializeShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot, const FFrameTime& InEvalTime )		Graph/MovieGraphSequenceDataSource.h
virtual void JumpDataSource ( const FFrameTime& InTimeToJumpTo )	Called by the Time Step system when the external data source should jump to the given time.	Graph/MovieGraphSequenceDataSource.h
virtual void MuteShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot )		Graph/MovieGraphSequenceDataSource.h
virtual void PauseDataSource()	Called by the Time Step system when the external data source should pause playback.	Graph/MovieGraphSequenceDataSource.h
virtual void PlayDataSource()	Called by the Time Step system when the external data source should start playback (time values will have been set by SyncDataSourceTime	Graph/MovieGraphSequenceDataSource.h
virtual void RestoreCachedDataPostJob()		Graph/MovieGraphSequenceDataSource.h
virtual void RestoreHierarchyForShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot )		Graph/MovieGraphSequenceDataSource.h
virtual void StopDataSource()	Called by the Time Step system when the external data source should stop playback (typically at the end of rendering).	Graph/MovieGraphSequenceDataSource.h
virtual void SyncDataSourceTime ( const FFrameTime& InTime )	Called by the Time Step system when it wants the external data source to update.	Graph/MovieGraphSequenceDataSource.h
virtual void UnmuteShot ( const TObjectPtr< UMoviePipelineExecutorShot >& InShot )		Graph/MovieGraphSequenceDataSource.h
virtual void UpdateShotList()		Graph/MovieGraphSequenceDataSource.h
