Which option is NOT one of the available choices for workspaces in video editing software?

In video editing software, workspaces refer to the arrangement of panels and tools that are tailored to specific tasks, allowing users to efficiently access the features they need for editing, color grading, audio mixing, and other processes. The options related to workspaces typically focus on managing the layouts and configurations of these panels.

The choice that stands out as not being a typical feature associated with workspaces is the ability to change playback speed. While changing playback speed is an essential function in video editing used to manipulate the timing of clips, it does not directly pertain to the arrangement or management of the workspace itself.

On the other hand, saving a new workspace, resetting to a saved layout, and saving changes to an existing workspace are all actions that involve customizing and managing the layout of the editing environment. These options help users maintain a consistent and personalized workflow, ensuring that they can always work efficiently according to their preferences.
