Camera Animation

TIP: This tool is supported in the perspective view and allows you to animate the camera and clipping planes.

Render > Camera Animation

Camera animation is a series of keyframes, capturing camera view properties and time, and connected in some way to generate a smooth movement between the keyframes.

The red timeline indicator indicates the current frame and time on the animation timeline. To change the current time of the indicator, left-click and drag it to a new position on the timeline. Press & hold the Shift key while dragging to snap to ruler lines. You can also use the right and left arrow keys to move the timeline indicator. The time code of the indicator (in the format hh:mm:ss:ff) is shown in the upper-right corner of the window.

Different intervals between ruler lines on the timeline are supported (one second in the above screenshot). Use the mouse wheel to zoom on the timeline until you see the desired interval.

Keyframe Operations

Insert, Select, and Delete

INSERT: Press Animate > Insert keyframe (Shortcut: I) to insert a new keyframe at the current time (position of the red indicator) and camera position.

TIP: When generating clip animations, enable the option Animate > Keyable actions before inserting the first keyframe.

SELECT: You can select and deselect keyframes as follows:

  • Left-click on a keyframe’s triangle clears the current selection and selects the new keyframe.
  • CTRL+left-click on a keyframe toggles its selection state.
  • Left-click on an empty space in the timeline clears the selection.
  • CTRL+A selects all keyframes.

DELETE: Press DEL key to remove selected keyframes.

Update

UPDATE CAMERA VIEWPOINT

  • Move the timeline indicator to the keyframe to be updated.
  • Move and align your camera as desired.
  • Press Animate > Update keyframe > Update camera viewpoint.

UPDATE CLIP ANIMATION

  • Move the timeline indicator to the keyframe to be updated.
  • Edit cross-section planes.
  • Press Animate > Update keyframe > Update keyable actions.

TIP: To move the timeline indicator exactly to a keyframe, use the Next keyframe and Previous keyframe actions, or double-click the triangle of a keyframe.

TIP: You can also press the keyboard shortcut U in the timeline to launch the Update keyframe context menu.

CHANGE TIMING: Left-click and drag the triangle of a selected keyframe to a new position on the timeline. Optionally press & hold SHIFT to snap to ruler lines.

Interpolation & Easing

To change the interpolation and easing mode, select a keyframe, click Animate > Set keyframe interpolation and select the desired option. The keyboard shortcut K will also activate the relevant context menu in the timeline.

INTERPOLATION: The interpolation mode affects the camera path segment between the selected keyframe and the following keyframe.

  • Cubic interpolation is the default and delivers a smooth movement.
  • Linear interpolation produces a straight connection between two keyframes. 
  • Constant holds the position of the selected keyframe until the following keyframe is reached.

EASING: Easing allows you to slow down the movement away from the selected keyframe (Ease in) and into the following keyframe (Ease out). In the default state, easing is deactivated. You can activate one or both and customize their strength.

TIP: You can change the interpolation and easing settings for multiple selected keyframes at the same time.

Timeline Navigation

  • Click to generate a camera path that tracks your movements in the scene.
  • Double-click the triangle of a keyframe to move the timeline indicator to the keyframe.
  • Click to move the timeline indicator to the start of the timeline (first frame). 
  • Click to move the timeline indicator to the previous keyframe.
  • Click to move the timeline indicator to the previous frame (Shortcut: Left arrow).
  • Click to playback the animation starting from the current position of the timeline indicator (Shortcut: Space). 
  • Click to pause the animation (Shortcut: Space).
  • Click to move the timeline indicator to the next frame (Shortcut: Right arrow).
  • Click to move the timeline indicator to the next keyframe.
  • Click to move the timeline indicator to the end of the animation sequence (last keyframe).

The speed of playback can be set to No sync or Real-time. In No sync, every frame will be displayed, which deviates from the real-time. The Real-time playback keeps up with real-time by skipping frames.

Other Features

FRAMES PER SECOND: Select the desired FPS setting from the dropdown menu. The options are 24, 30, and 60 FPS.

INSPECT: To view the camera path in the third person, toggle the Inspect button. Along the red camera path, each frame is represented by a white dot and each keyframe by a blue dot. Adding, moving, or removing keyframes can be performed in the inspect mode. To edit the camera position or orientation of a keyframe, exit the inspect mode.

RENDER VIDEO: Once you finish creating your camera animation, you can render it to a video or image sequence. Click Export to open the Render Video window.
