If you don't want to make this yourself, you can find the easy-to-use fireworks pack here.

In this video tutorial, you'll learn how to create realistic fireworks in Adobe After Effects. We will be using the plugin Trapcode Particular, but you can still follow this tutorial even if you don't have the plugin.

You can also purchase the 15 pre-made elements that we have already created. These elements can be easily used with any kind of editing software, without any plug-ins.
