By default, the Timelines Only button in the Browser is enabled, which allows Wiretap content to be presented in a timeline form. You can also choose to display the one-sequence representation of the Wiretap timeline by disabling the Timelines Only button, in which case both the one-sequence and timeline versions are displayed at the same time.

The difference between the two is as follows:

• One-sequence: a sequence of files is presented to Lustre with clip metadata as opposed to timeline metadata and you can still see transitions as 'read-only'. This is useful, for example, when manually comparing the contents of the timeline against a digital cut captured directly from an offline video tape. See Performing a Confidence Check.
• Timeline: a sequence of shots that contains source clip metadata (for example, shot name, source timecode), dissolve, and cut transitions. This allows you to recreate the timeline that you had in your Visual Effects and Finishing application (in a single-layer format) when you import the Wiretap timeline. You can then grade each shot and render back either a single-sequence clip or render with the timeline structure intact.

Additionally, you can choose to display the clip thumbnails with or without details about the clips by enabling Details for a detailed view or Proxies for thumbnail-only view. For more information about the Browser, see Accessing the File Browser.
