As a video production professional, it's important to maintain an ongoing collection of assets that you can pull from and use in various projects. Whether it's stock footage, sound effects, music, templates, or graphics, having a robust library is an invaluable resource.

Currently I have a folder on my main hard drive labeled "_Toolbox." Inside are several subfolders which are used to organize all of my assets by type, such as:

• Sound Effects

• Stock Footage

• After Effects Templates

• Graphic Elements

• LUTs

• Forms

Your collection might look different from mine. You might have more folders. You might have less. The important thing is to always be on the lookout for new elements that you can add to your library so it always reflects current visual trends.

Here are a few resources I turn to when I need additional content for my Toolbox:
