What does an Edit Decision List (EDL) primarily do?

An Edit Decision List (EDL) primarily serves to number and identify each frame of the camera roll, providing a detailed record of the edits made during the post-production process. By listing the in and out points of each edit along with corresponding timestamps, an EDL helps editors keep track of the footage they are working with and ensures that the final product will accurately reflect their creative decisions. This tool is vital for organizing clips, maintaining continuity, and facilitating smooth communication between the editing team and others involved in the film production.

In contrast, while importing audio files, storing video effects, and exporting finished films are essential tasks in the post-production workflow, they do not encompass the primary function of an EDL, which is specifically focused on documenting the editing process.
