Motion Blur

Add a cinematic feel to your recordings with GPU-accelerated motion blur effects. Motion blur smooths out fast movements and zoom transitions, giving your recording a more polished, professional look.

Enabling Motion Blur

Toggle motion blur on or off from the Advanced tab in the editor. When enabled, motion blur is applied to zoom transitions and fast cursor movements throughout the recording.

Settings

Strength

Controls the overall intensity of the blur effect, from 1% to 100%. Lower values produce a subtle smoothing effect; higher values create a more dramatic cinematic blur.

  • Low (1–20%) — Barely noticeable, just softens harsh transitions
  • Medium (20–50%) — Visible blur on zoom transitions, gives a polished feel
  • High (50–100%) — Strong, cinematic blur for dramatic effect

Shutter Angle

Controls how much of each frame’s motion contributes to the blur, measured from 36° to 360°. This mimics the shutter angle of a physical camera:

  • Low (36–90°) — Minimal blur, sharper frames
  • Medium (180°) — The standard cinematic look — equivalent to a 180° shutter angle, the default for film
  • High (270–360°) — Very long exposure, heavy blur on any movement

Quality (Samples)

Controls how many intermediate frames are blended to produce the blur, from 4 to 16 samples:

  • 4 samples — Fastest rendering, may show slight stepping in extreme blur
  • 8 samples — Good balance of quality and speed
  • 16 samples — Smoothest results, slower to render

GPU Acceleration

Motion blur rendering uses WebGL for hardware acceleration. The blur is computed on your GPU, keeping the editor preview responsive even with high quality settings. During export, motion blur is rendered as part of the final video pipeline.

When to Use Motion Blur

Motion blur works best in these situations:

  • Zoom transitions — Smooth the zoom-in and zoom-out animations for a cinematic feel
  • Fast cursor movement — Reduce the “teleporting” look when the cursor moves quickly across the screen
  • Speed changes — Make sped-up sections look more natural

Motion blur is less useful (and can reduce clarity) in:

  • Slow, detailed tutorials — Viewers need to see every frame clearly
  • Text-heavy recordings — Blur can make text harder to read during transitions
  • Static content — No movement means no blur effect
