Zoom Effects Timeline

Table of Contents

Overview

The Zoom Effects tab in the timeline lets you animate zoom and focus changes across your video. It works like a keyframe editor — you place keyframes at specific points in time, and the video smoothly interpolates between them.

The Two Lanes

The Zoom Effects timeline has two independent keyframe lanes:

Lane What it controls
Zoom How much the video is zoomed in at a given point. Keyframes appear as grey diamonds.
Pos Where the camera is focused — the X and Y coordinates of the focal point. Keyframes appear as blue diamonds.

The two lanes work together. At any point in time, the video uses the current zoom level from the Zoom lane and the current focus position from the Pos lane. You can place keyframes on either lane independently.


Toolbar Controls

Control Requires Selection Description
+ Add Zoom Keyframe No Adds a zoom keyframe at the current playhead position
+ Add Position Keyframe No Adds a position keyframe at the current playhead position
Delete Yes — a keyframe must be selected Removes the selected keyframe

Delete only appears in the toolbar when a keyframe is selected.


Adding Keyframes

  1. Move the playhead to the point in the timeline where you want the zoom or position to change.
  2. Click + Add Zoom Keyframe or + Add Position Keyframe.
  3. A new keyframe is placed at the playhead position on the corresponding lane.
  4. Click the keyframe to select it and adjust its properties in the sidebar.

Repeat this at different points in the timeline to create a sequence of changes. The video will animate smoothly between keyframes according to the easing setting on each one.


Zoom Keyframe Properties

Zoom Keyframe properties panel in the Screen Script Editor

Clicking a zoom keyframe opens the Zoom Keyframe panel in the sidebar with two controls:

Zoom A slider that sets the zoom level at this keyframe. Drag the slider right to zoom in further, or left to reduce zoom.

Easing to Next Controls how the video transitions from this keyframe to the next zoom keyframe:

Option Behaviour
Linear The zoom changes at a constant speed between keyframes
Smoothstep The zoom eases in and out — it starts slow, accelerates through the middle, and slows again at the end

Position Keyframe Properties

Clicking a position keyframe opens the Position Keyframe panel in the sidebar.

Position A live preview of your video is shown. A circular pointer indicates the current focal point. Drag the pointer anywhere on the preview to set where the video focuses at this keyframe.

The position is defined as X and Y coordinates, each ranging from 0 to 100:

Axis 0 100
X Left edge of the frame Right edge of the frame
Y Top edge of the frame Bottom edge of the frame

Easing to Next Controls how the focus position moves between this keyframe and the next:

Option Behaviour
Linear The focus point moves at a constant speed
Smoothstep The movement eases in and out for a more natural camera feel

Deleting a Keyframe

  1. Click on a keyframe in either lane to select it.
  2. Click Delete in the toolbar.

The keyframe is removed and the video will interpolate directly between the surrounding keyframes.
