How Media Composer Works: Files and Relationships
How Media Composer Works:
Files and Relationships
Before starting Media Composer, it’s important to know where everything
“lives” within your Avid project and how Avid interacts within the entire
editing system.
The Avid Project Folder Hierarchy
An Avid project is not a single file; rather, it is a file within a folder that con-
tains the main project components. Don’t worry, Avid automatically creates
all these files every time you set up a project. Still, it’s good to know what
everything is and where everything is located.
Project: A project is an Avid structure for organizing your work. When you
create a project, the system creates two items: a file and a folder. A proj-
ect folder can be stored anywhere: in a dedicated Avid Projects folder on
your computer, on an external hard drive, or on a thumb drive. It’s a rela-
tively small file, so it can even be attached to an e-mail.
The project file (.avp) contains all the information about your current job.
Clicking the .avp file in the project folder will start the project. The project
folder contains all the files of your project, including the project file, project
settings (.avs), and bins (.avb). A bin is the electronic equivalent of a physi-
cal bin in which film is stored for retrieval during editing. The bin is simply a
file that contains clips and sequences. Bins are stored in the project folder.
A bin can contain three types of components:
Clip: A clip is stored in a bin and contains all the information about the
source of the material—tape name, timecode information, and so on.
Subclip: A subclip is a subset of a clip.
