Which file format is commonly used to exchange track information between audio and video software across different platforms?

• A. AAF
• B. B-Roll
• C. Aspect Ratio
• D. Blimp

Answer: (A)

Interchange formats for project data are used to move track layouts, edits, and metadata between audio and video software on different platforms. The best answer is AAF, which stands for Advanced Authoring Format. AAF is designed to carry timelines, clip references, transitions, effects, and other metadata so that a sequence created in one program on one platform can be read and reconstructed in another program on another platform. This makes it the standard way to exchange track information across tools used in audio and video post-production.

The other options aren’t formats used for transferring project data. B-Roll refers to extra footage, Aspect Ratio is a display characteristic of the image, and Blimp is a windscreen for a microphone.
