OpenShot Blur Effects Tutorial

Introduction

• Objective: Learn to add blur effects to a video using OpenShot.
• Types of Blurs:
  • Soft Blur: Applied to the entire video, primarily for transitions.
  • Pixelated Blur: Can be applied to the entire video or specific parts.

Soft Blur Effect

• Usage: Ideal for transitions between scenes or at the start of a video.
• Application:
  • Adjust Horizontal Radius, Vertical Radius, and Iterations to achieve desired effects.
  • Set Iterations to 0 to remove blur.
  • Configure radii to create different horizontal/vertical blur effects.
  • Increasing Iterations results in a softer blur but takes longer to render.
  • Properties are keyframe-interpolated for animation, requiring precise Playhead positioning.

Adding Soft Blur Transition

• Implementation:
  • Animate for the first 2 seconds, starting with both radii set to 25 and Iterations to 10.
  • At 2-second mark, set both radii to 0.
  • Use Bezier Ease-In interpolation for smooth transition fade-out.

Pixelated Blur Effect for Static Objects

• Example: Blurring a café's name.
• Process:
  • Apply the Pixelate effect to cover static items.
  • Adjust margins to only blur desired area.
  • Reduce Pixelization value for smaller pixel size.

Pixelated Blur Effect for Moving Objects

• Example: Blurring a moving person's face.
• Steps:
  • Add a Pixelate effect and initially hide it by setting margins to 1.
  • Configure margins to cover moving face, using keyframes to track movement.
  • Utilize Constant interpolation mode to prevent premature blur appearance.
  • Set keyframes for movement and adjust margins to maintain coverage.
  • Disable blur when not required by resetting margins.
