How can you view if a clip has been used in a sequence?

To determine if a clip has been used in a sequence, hovering over the filmstrip icon associated with the clip provides essential information. This action displays a tooltip that indicates whether the clip is present in any sequences. This feature allows for a quick method of checking a clip's usage without needing to interact with the timeline or other more complex workflows.

The other methods indicated would not provide direct confirmation of a clip's usage in the same efficient and straightforward way. Right-clicking the clip typically brings up context options, while opening the clip in the Program Monitor focuses on the clip's content rather than its connections to sequences. Dragging the clip to the timeline is an action that would not specifically inform you of its prior use in sequences; rather, it could introduce the clip into a sequence for the first time.
