This is using manual setting to design the lights with Turbulent Noise (effect).
First adjust the brightness. Then set lower complexity (around 2.0) and scale (7,000).
Then set the Evolution to move the lights.
Next, set the footage to screen mode, and reduce the opacity.
You can also add in color with Fill (effect).
This is pretty simple because you just need to import Light Leaks footage and set the mode to Screen.
this is my collection of Light Leaks Video Footage (Free)
This is my outcome of applying the techniques which i have learned.
