The Light Hits work as footage and need to be imported to our footage bin. They are no preset or plugin!
After importing you drag your favourite light hit into your timeline and drop it onto the footage you want to have the effect on.
Then select the blending mode screen to let show the footage under the effect. You can play around with the luma curves on the effect but in general the effect is ver decent already.
