Taking control of the camera during cutscenes in Unreal Engine is a crucial aspect of crafting captivating cinematic experiences. By gaining mastery over the camera, you can guide the audience’s perspective, emphasize key elements, and create a sense of immersion that draws them into the story. This article will delve into the techniques and considerations involved in controlling the camera from a cutscene, empowering you to create visually stunning and emotionally resonant cinematic moments.
To begin, it’s essential to understand the camera’s role in cutscenes. Unlike gameplay segments where the player controls the camera, cutscenes present a fixed perspective determined by the game designer. This allows for precise composition and cinematic techniques that enhance the narrative impact. By manipulating the camera’s movement, framing, and depth of field, you can guide the audience’s attention and create a sense of suspense, awe, or intimacy as the story unfolds.
Controlling the camera in Unreal from a cutscene involves utilizing the Level Sequence Editor. This powerful tool provides a timeline-based interface where you can create keyframes to animate the camera’s position, rotation, and focal length. By interpolating between keyframes using various easing curves, you can achieve smooth and dynamic camera movements that mimic the techniques used in filmmaking. Additionally, the Level Sequence Editor allows for advanced features such as post-process effects, camera shake, and motion blur, enabling you to create immersive and visually engaging cutscenes.
Establishing Camera Control Hierarchy
Establishing a clear camera control hierarchy is crucial for managing the movement and positioning of cameras in Unreal Engine within cutscenes. This hierarchy defines the parent-child relationships between different camera components, enabling you to control the overall perspective and movement of the cutscene.
To establish a camera control hierarchy, you’ll need to create multiple Camera components in your scene. Each Camera component can have a parent Camera component, forming a hierarchical structure. The root or “master” Camera component at the top of the hierarchy will control the overall movement of the camera system.
When defining the hierarchy, determine the logical parent-child relationships between the cameras. For example, if you want to create a cutscene with multiple camera shots, you might have a top-level Camera component as the root, with child Camera components for each individual shot. This allows you to control the overall camera movement for the entire cutscene and switch between specific camera shots as needed.
Once the camera hierarchy is established, you can use Blueprints or Sequencer to control the camera movement and transitions. By setting keyframes and manipulating the camera’s transform properties, you can create smooth and dynamic camera movements within your cutscene.
Defining Camera Paths and Spline Points
Camera paths in Unreal Engine are defined using splines, which are curved lines that control the camera’s movement. Spline points are the individual control points that determine the shape and direction of the path. To create a camera path, you can either use the built-in spline editor or create your own using Blueprint scripting.
Creating a Camera Path in the Spline Editor
To create a camera path in the spline editor, follow these steps:
- Select the “Create New” button in the Modes panel.
- Choose “Spline” from the dropdown menu.
- Click and drag in the viewport to create the points of the spline path.
- Right-click and select “Set Start” or “Set End” to define the start and end points of the path.
Once you have created your path, you can assign it to a camera actor. To do this, select the camera actor and in the Details panel, find the “Spline” property. Drag and drop your spline path into this property.
Controlling Camera Movement Along the Path
Once you have assigned a path to a camera actor, you can control the camera’s movement along the path using the “Camera Position” property in the Details panel. This property determines the position of the camera on the path. You can also control the camera’s speed and rotation using the “Camera Speed” and “Camera Rotation” properties, respectively.
| Property | Description |
|---|---|
| Camera Position | The position of the camera on the spline path. |
| Camera Speed | The speed at which the camera moves along the path. |
| Camera Rotation | The rotation of the camera as it moves along the path. |
By adjusting these properties, you can create dynamic and engaging camera movements that follow your characters or objects as they move through the game world.
Using Timeline Sequences to Control Camera Movement
Timeline sequences offer a powerful and intuitive way to choreograph camera movements within cutscenes. They provide precise control over camera position, rotation, and field of view (FOV).
Creating a Timeline Sequence
To create a timeline sequence, navigate to the Sequencer tab within the Unreal Editor. Click on the Create New Take button and select Timeline Sequence from the dropdown menu.
Adding a Camera Curve
Once the timeline sequence is created, add a camera curve by clicking the Add button and selecting Camera. This curve will control the camera’s movement throughout the cutscene.
Setting Camera Keyframes
To define how the camera moves, set keyframes along the timeline. Each keyframe represents a specific point in time where the camera has a specific position, rotation, and FOV.
- Set Initial Position: Click on the first frame on the timeline and adjust the camera’s position, rotation, and FOV in the View Transform panel.
- Add Keyframes: Add additional keyframes at the desired intervals throughout the cutscene. Each keyframe represents a new camera position, rotation, or FOV.
- Smooth Interpolated Keyframes: By default, the camera will move linearly between keyframes. However, you can smooth out the movement by enabling Interpolation and adjusting the Interp Curve in the Curve Editor.
Advanced Camera Control Techniques
In addition to controlling camera position, rotation, and FOV, you can use timeline sequences to control advanced camera techniques, including:
Camera Blending
Blend between multiple camera viewpoints seamlessly by adding multiple camera curves and assigning them different blend weights. This allows for smooth transitions between different perspectives.
Camera Shake
Add camera shake to simulate motion or create dramatic effects. This can be achieved by adding noise functions to the camera’s position and rotation keyframes.
Camera Focus
Control the camera’s focus point to draw attention to specific elements within the scene. This is useful for guiding the viewer’s attention during cutscenes.
Integrating Cine Cameras with Cinematics
In order to integrate Cine Cameras with Cinematics, you’ll need to create a Cine Camera Actor and place it in your scene. Then, you’ll need to create a Cinematic and assign the Cine Camera Actor to it. Finally, you’ll need to add a Camera Cut Track to the Cinematic and set the camera cuts to the desired shots.
Adding Camera Cuts
To add camera cuts to a Cinematic, you’ll need to right-click on the Cinematic and select “Add Track” > “Camera Cut Track.” This will create a new Camera Cut Track in the Cinematic. You can then right-click on the Camera Cut Track and select “Add Camera Cut” to create a new camera cut.
Setting Camera Cuts
To set the camera cuts, you’ll need to select the camera cut and then set the following properties:
- Camera: The Cine Camera Actor that will be used for the shot.

- End Time: The time at which the camera cut will end.
Controlling Camera Movement
You can control the camera movement of a Cine Camera Actor by using the following properties:
- Focal Length: The focal length of the camera.
- Aperture: The aperture of the camera.
- Shutter Speed: The shutter speed of the camera.
- ISO: The ISO of the camera.
Camera Field of View:
The camera field of view (FOV) determines how wide the camera’s view is. A wider FOV will capture more of the scene, while a narrower FOV will focus on a smaller area. You can adjust the FOV of a Cine Camera Actor by using the “Field of View” property in the Details panel.
| FOV | Description |
|---|---|
| Wide (over 90 degrees) | Captures a large field of view, showing more of the surroundings. Useful for establishing shots or capturing wide-angle views. |
| Medium (60-90 degrees) | Provides a balanced field of view, suitable for general shots and close-ups. |
| Narrow (less than 60 degrees) | Zooms in on a specific area, creating a more focused or zoomed-in shot. Good for close-ups or detailed shots. |
Setting Camera Target and Focus
In order to control the camera’s target and focus from a cutscene, you will need to use the following steps:
- Create a camera actor. This will be the camera that you will use to film your cutscene.
- Position the camera actor. Place the camera actor in the desired location for your cutscene.
- Create a target actor. This will be the actor that the camera will focus on.
- Position the target actor. Place the target actor in the desired location for your cutscene.
- Set the camera’s target. In the camera actor’s properties, set the "Target Actor" property to the target actor.
- Set the camera’s focus. In the camera actor’s properties, set the "Focus Target" property to the target actor.
The camera will now follow the target actor as they move around the scene. You can use the "Camera Settings" tab in the camera actor’s properties to adjust the camera’s settings, such as the field of view, aperture, and shutter speed.
| Property | Description |
|---|---|
| Target Actor | The actor that the camera will follow. |
| Focus Target | The actor that the camera will focus on. |
| Field of View | The angle of view of the camera. |
| Aperture | The size of the camera’s aperture. |
| Shutter Speed | The speed at which the camera’s shutter opens and closes. |
Adjusting Camera Field of View and Focal Length
The field of view (FOV) determines how wide or narrow the camera’s view is. A wider FOV captures a broader perspective, while a narrower FOV focuses on a smaller area. By adjusting the FOV, you can control the scope and composition of your shots.
Similarly, the focal length affects the camera’s perspective. A shorter focal length creates a wide-angle view, while a longer focal length provides a narrower, more zoomed-in view. Manipulating the focal length allows you to emphasize specific elements and establish depth within the scene.
Recommended Settings for Different Camera Types
| Camera Type | FOV (degrees) | Focal Length (mm) |
|---|---|---|
| Wide-angle | 60-100 | 10-24 |
| Normal | 40-60 | 24-50 |
| Telephoto | 20-40 | 50+ |
Tips for Adjusting Camera Field of View and Focal Length
Consider the following tips when adjusting camera settings for cutscenes:
- Experiment with different FOVs to create a sense of intimacy or grandeur.
- Use a wider FOV for wide-angle shots and an extreme close-up for telephoto shots.
- Adjust the focal length to control the depth of field and isolate specific characters or objects.
- Combine multiple camera angles and FOVs to create a dynamic and engaging cinematic experience.
