摘要
The disclosed computer-implemented method may include (1) accessing a first media data object and a different, second media data object that, when played back, each render temporally sequenced content, (2) comparing first temporally sequenced content represented by the first media data object with second temporally sequenced content represented by the second media data object to identify a set of common temporal subsequences between the first media data object and the second media data object, (3) identifying a set of edits relative to the set of common temporal subsequences that describe a difference between the temporally sequenced content of the first media data object and the temporally sequenced content of the second media data object, and (4) executing a workflow relating to the first media data object and/or the second media data object based on the set of edits.

This application claims the benefit of U.S. Provisional Application No. 63/054,132, filed 20 Jul. 2020, the disclosure of which is incorporated, in its entirety, by this reference.
Media production may involve various and sometimes interdependent production tasks. Accordingly, when a new cut of a media asset is provided during the production process, one or more production teams and/or computing tasks may be implicated. Unfortunately, it may be difficult and laborious for production teams to determine whether and what steps are needed when a new cut is provided, resulting in a significant amount of labor as well as the likelihood of oversights or mistakes.
