Parameters:
Blur Type “Constant” simulates motion blur. “Soft” adds gentle streak. One-Way modes include offset visual movement.
Size Sets blur intensity (–4.0 to 4.0). Negative values reverse direction.
Variation (Size) Animate blur power. Use 0.0 to lock blur strength and vary mask or direction only.
Area Controls blurred region’s width: 0.0 = none, 1.0 = full frame. Keyframe for dynamic expansion.
Variation (Area) Lets the blurred region grow/shrink dynamically.
Direction Sets blur angle: 0.0 = horizontal, 1.0 = full rotation. Values up to 100.0 create directional animation.
Variation (Direction) Animates blur angle over time. Zero locks it in place.
Side Controls direction mask placement: 0.0 = left, 0.25 = top, 0.5 = right, 0.75 = bottom. Up to 100.0 for animation.
Variation (Side) Randomizes mask side for directional emphasis across frames.
Distribution Softens mask edges. Higher = smoother transition between blurred and unblurred areas.
