The smoke effect covers the video image with smoke.
SLIDERS
Amount - Controls the number of puffs of smoke.
Opacity - Controls the thickness of each puff of smoke.
Direction - Controls the direction that the smoke is flowing.
USAGE
Smoke can be used in conjunction with Rain, Heat or Flame to enhance the effect. By adjusting the direction and making the effect move from side to side, a rolling fog effect can be created.
The Sparkle effect adds sparkles to the moving portion of an image.
SLIDERS
Amount - Amount of sparkles.
Concentration - Controls the thickness of concentration of the sparkles.
Size - Controls the size of each sparkle.
USAGE
The Sparkle effect is best on footage that is shot with a camera which is set on a tripod. Since it applies sparkles wherever motion is detected, if the camera moves, the whole images may be counted as being "in motion."
If the concentration parameter is set to its highest setting, a sparkle will be placed on every pixel in motion, but be prepared for the effect to slow down quite a bit. Setting the concentration parameter lower will yield much faster speed.
