After Effect- Importing Footage
We can import source files in the After effect project as the basis for footage items, and we can use these sources for layers. We can work with the footage items in the Project panel first. We can import different types of files, collection of files, or components of files as sources for individual footage items. It also includes moving image files, still-image files, still-image sequences, and audio files. When we import any files to the After Effect, it does not copy any data itself into our project but creates a reference link to the footage item's source. This helps in keeping project files relatively small.
Note: If you try to delete, rename, or move an imported source file, the reference link will be broken to that file.
Supported import formats
Importing and using some of the files in After Effect Requires the installation of additional import plug-ins. Adobe Premiere Pro can import so many formats that After Effects can't import, so you can use Premier to bring data into After Effect in many ways. We can also extend the ability of After Effects to import additional file types by installing additional codecs. Some of the following extensions demote the container file formats rather than denoting specific audio, video, or image data format.
MOV, AVI, MXF, FLV, and F4V
Audio formats supported by After Effect
Video and animation formats
We can also import the Final Cut Pro projects into Premiere Pro, and then we can fetch that project's components into the After Effects.
