Motion 5 effect

Im a beginner in Motion 5 and final cut pro x and would like to know how to create these colored bubble effects in your videos. In the video below, you can see these bubbled effects throughout the video. Thanks.

I think some folks refer to those as Bokeh Lights. I'd start with a plain white circle shape (hit C, hold shift while click-drag in Canvas). Then make it a Replicator (circle with random fill). Play with the Replicate Seed's Generator button to change up the pattern.

Color Mode set to "Over Pattern" and adjust to taste. I'd also play with the "Color Repetitions" control, maybe apply a Randomize parameter behavior to it, and turn it down a bit.

The Scale parameter in the Cell Controls section of the Replicator will help control how large/small the lights are. Perhaps play with the Scale Randomness setting, too.

A simple Gaussian filter will blur it.

I am new also and most helpful your suggestion great for me. Can you help me to know that which software I have to use.
