The files you use to assemble an Adobe After Effects project are called footage items, and include video footage, still images and audio files. You import these files into the Project panel and then drag them into the After Effects timeline to build your project. You can sort and organize the files in the Project panel if you have a complicated project, and you can refresh or reload the files if you've made changes to them after you loaded them in the project.
Open After Effects. Load an existing project or click "File" and then "New Project."
Right-click the Projects panel and click "Import." Select "Multiple Files." Click a file to select it and then click "Open." Continue adding files until you have imported all files for your project. Click "Done."
