What does timeline integration refer to in post-production workflows, and how do metadata/XML/AAF facilitate it?

• A. Using metadata/XML/AAF to align audio with picture across systems.
• B. Posting and archiving the project.
• C. Editing the video timeline without audio.
• D. Exporting the color grade metadata.

Answer: (A)

Timeline integration is about keeping the edit sequence in sync across the different tools used in a post workflow, so audio and picture stay aligned as you move data between editors, audio mixers, finishing tools, and even across different studios. Metadata, XML, and AAF are standard interchange formats that carry the essential timing and structure of a project: the edit decisions (cuts, trims, transitions), the track layout, media references, and timecode information. An AAF file can transmit the sequence with its audio/video links and effects so another system can reconstruct the exact timeline. XML exports often convey project structure, markers, and frame-accurate timing, helping different applications import the timeline reliably. Metadata adds the necessary descriptive details—timecode, frame rate, channel mapping—so everything remains synchronized when the project moves between software. In short, this approach enables seamless collaboration and consistent audio-to-picture alignment across systems. The other options describe tasks that don’t address cross-system timeline synchronization, such as posting/archiving, editing timelines without audio, or exporting color-grade data.
