Which file format stores all track information and is compatible across DAWs and NLEs?

• A. B-Roll
• B. 2-pop
• C. AAF
• D. Aspect Ratio

Answer: (C)

The main idea here is a file format designed to transfer complete project structure between different audio and video editing systems. AAF (Advanced Authoring Format) is built for interoperability, carrying an entire timeline: multiple tracks, edit decisions, transitions, and related metadata, so a project can be moved from one DAW or NLE to another with the essential track information preserved. That’s why it’s the best choice for cross-compatibility.

The other options aren’t file formats used for project interchange. B-Roll refers to secondary footage, not a data container. A 2-pop is a slate cue used for synchronization, not a project-exchange format. Aspect ratio describes the frame’s shape, not how edits and tracks are stored. So AAF uniquely fits the need to store and transport track information across DAWs and NLEs.
