The Input parameters for the Particle Blast effect create a transition effect that turns the foreground video into particles that blow off to reveal the background video. For more information, see Particle Blast.

Amount

Sets the progression of the effect. The larger the difference in the Amount value between keyframes, the faster the effect happens.

Size

Sets the radius of the particles.

Spacing

Sets the space between the center of the original position of the particles.

Front Speed

Controls whether the particles in the center of the blast start to move before the particles at the outside edges.

Front Randomness

Allows particles nearest the center to move at different speeds.

Speed

Sets the speed at which particles move apart.

Speed Randomness

Allows particles to move at different speeds to give a more natural effect.

Acceleration

Controls how quickly a particle reaches the full speed of the blast. The higher the value, the more quickly the particle reaches full speed.

Bumpiness

Adds a shadow to the edge of the particles.

Swap Sources

Specifies whether to apply the effect to incoming or outgoing video.
