Keyframes let you animate captions and image overlays by setting a starting position and an ending position. Captions automatically generates the motion between them. The result is captions that fly in, drift across the screen, zoom out, or move to follow the action.

​
How keyframes work

Think of a keyframe as a marker in time with a position attached. You set two keyframes:
  1. Keyframe 1: where the caption starts (position, size, rotation)
  2. Keyframe 2: where the caption ends
Captions animates the transition between the two over the duration of the segment. You choose the animation curve: linear, ease, or instant.

​
When to use keyframes

  • Hook moments: animate your opening caption to fly in for impact
  • Emphasis: move a caption to point toward something in the frame
  • Reaction shots: have a word zoom out as it’s spoken for emphasis
  • Dynamic storytelling: keep the viewer’s eye moving across the screen
  • Logo or brand element animation: make an image overlay drift across the frame

​
Adding a keyframe

1

Select the caption or overlay you want to animate

Tap the caption or image overlay in the editor. Make sure you’re on the segment you want to animate.
2

Tap Keyframes

In the caption editor, tap Keyframes to open the keyframe panel.
3

Set your first keyframe

Move the playhead to the moment where you want the animation to start. Drag the caption to the starting position. Pinch to resize if needed. This is Keyframe 1.
4

Set your second keyframe

Move the playhead to where you want the animation to end. Drag the caption to the ending position. This is Keyframe 2.
5

Choose your animation curve

Select from three options:
  • Linear: constant speed throughout
  • Ease: starts slow, accelerates, then slows at the end. Feels natural for most movements.
  • Instant: snaps from position to position with no transition. Good for cuts or emphasis.
6

Tap Apply

Tap Apply to preview the animation. Scrub through the timeline to see it in motion.

Tips for effective keyframe animation

  • Less is more. One or two animated moments per video is impactful. Every caption animating is chaotic.
  • Use ease for natural movement. Linear animation looks mechanical. Ease almost always feels better.
  • Match the energy of the content. A calm, educational video calls for subtle drift. A high-energy short clip can handle a bigger, faster move.
  • Animate the hook caption. The opening caption is the highest-value animation in any video. A caption that comes in with purpose makes the viewer feel like something is happening.
  • Use keyframes on image overlays too. A product image that drifts slowly across the frame is more engaging than a static one.

​
Example: hook caption animation

This is one of the most common and effective uses of keyframes:
  1. Place your hook caption in the lower third of the screen
  2. Set Keyframe 1 at the very start of the video, with the caption positioned just off-screen at the bottom
  3. Set Keyframe 2 at 0.5 seconds, with the caption in its final position in the lower third
  4. Choose Ease curve
  5. The caption slides up into frame at the start of the video
Result: the viewer’s eye is drawn to the caption the moment the video starts.
