Effects Presets are not effects! They are a layered list of different effects (or several instances of a single effect) that have been added to a storyline clip to create a visual effect. When you select and add a preset to a clip, that layered list of effects that were saved as a preset are rebuilt for that clip. This is a tremendous time saver!
Highlighter 2 is an easy effect to use but may take some time to learn its full potential. Here you will find free presets created using Highlighter 2 Effects made by Sight-Creations. You can download these presets and find out how the effect was created, use them to study how to create similar effects or simply just use them! Enjoy!
