Motion blur is an impactful visual aid that amplifies the feeling of speed, movement, and authenticity in videos. You can seamlessly incorporate this effect using After Effects, a widely favored software for video editing and motion graphics, thus amplifying your visuals.

What Is Motion Blur

Motion blur replicates the natural phenomenon where moving objects continue to move between the time it takes light to reach our eyes. In After Effects, this is achieved by replicating and offsetting the layer multiple times, tied to the layer’s animation speed and direction.

When to Use Motion Blur

Motion blur should be used intentionally, and is particularly effective with live-action footage or 3D animation. It’s less suited for 2D scenes or scenes where color is critical, as it can remove detail and muddy colors.

Motion Blur vs. Smears and Multiples

Animators often use old-school techniques like smears and multiples to replicate motion blur artistically, especially in cell animation. These techniques offer a stylistic approach to indicating rapid movement.

Applying Motion Blur in After Effect

After Effects offers a built-in tool for motion blur. The process involves selecting the moving layer and clicking the motion blur layer switch in the toolbar. For more stylized control, the CC Force Motion Blur effect in the Effects menu under Time offers additional settings like Motion Blur Samples and Shutter Angle.

Using Third-Party Plug-ins

For advanced control, third-party plugins like Boris FX’s BCC Motion Blur offer comprehensive options for different blur types, such as radial, channel, and directional blurs.

Creative Considerations

Deciding when to add motion blur is a creative choice. It’s useful for smoothing high-speed shots, creating a cinematic effect, integrating visual effects elements seamlessly, simulating faster movements or camera panning, and more.

Additional Stylized Blur Effects

Other effects like the Time warp Effect for speed adjustments and the Pixel Motion Blur for computer-generated motion can be explored. Third-party plugins provide unique blurs like anime or “matrix” effects.

How do you incorporate the motion blur effect?

By adhering to the steps below, you’ll be able to add this enhancement to your footage in After Effects, thereby intensifying the perception of motion and speed in your clips. Make sure to play around with the settings to reach your desired outcome:

• Step 1: Launch After Effects and bring in the footage you wish to enhance with this tool. Navigate through File > Import > File and pick your video file from the chosen location on your computer;
• Step 2: Post import, craft a new composition by selecting Composition > New Composition. Adjust your composition preferences, like frame rate and resolution, then click OK;
• Step 3: Within the Timeline panel, highlight your footage layer. Next, from the Layer menu, opt for Switches > Motion Blur to activate motion blur for the chosen layer. A motion blur icon will be visible next to the layer name within the Timeline panel;

• Step 4: To meticulously adjust the motion blur effect, reselect the layer and head to the Effect menu. Expand the “Time” category and find the “Directional Blur” effect. Apply the effect to the layer either by dragging it to the layer or double-clicking its name;
• Step 5: Once the Directional Blur is applied, you can alter various settings to manage the appearance and intensity of the motion blur. Key parameters to tweak are the blur’s length and angle as these determine the blur’s extent and direction. Experiment with different values until you achieve your desired result;
• Step 6: Preview and refine. To visualize the motion blur effect, utilize the preview functions in After Effects. Hit the spacebar to play back the composition and review the result. If needed, modify the motion blur properties or experiment with additional features to meet your desired outcome.

Enable Motion Blur

• Load your footage into After Effects;
• Select the moving layer to add motion blur;
• Click the motion blur layer switch found above the layer menu in the toolbar;
• Go to the layer toolbar and click “Enable Motion Blur.”;
• This effect can also be applied to text elements or animation, and for computer-generated motion, the pixel motion blur can be used​​.

CC Force Motion Blur Effect

• After selecting the moving layer, go to the Effects menu;
• Choose Time, then select “CC Force Motion Blur.”;
• This opens the CC Force Motion Blur dialog box, providing more control options like Motion Blur Samples, Shutter Angle, and Native Motion Blur;
• Check the “Override Shutter Angle” box to ensure your settings override the native shutter speed;
• Experiment with these settings for the best results as each footage might require different adjustments​​.

Third-Party Plug-ins

• For even more control and advanced options, third-party plugins like Boris FX’s BCC Motion Blur can be used;
• This plugin, part of the Continuum Visual Effects Plug-ins pack, offers a range of blurs including radial, channel, and directional blurs;
• Such tools provide complete control over the type of motion blur applied to the footage, enhancing its visual appeal significantly​​.

Upon satisfaction with the result, it’s time to render and export the completed video. Navigate to Composition > Add to Render Queue and choose your preferred output settings, such as format, resolution, and destination. Lastly, hit the Render button to initiate the rendering process.
