HD video overlay with a lot of colored bubbles. Instructions of using: set the composite or transfer mode to screen or adjust video layer opacity to one you need and control the opacity to taste with keyframing. If you'll need to change the color of this transition - try to add Levels, Color Balance or HSL (Hue-Saturation-Lightness) Color Adjustment filters to that video layer and play around with the filter properties.
