What does selecting 'Timecode Overlay During Edit' enable in the Program Monitor?

Selecting 'Timecode Overlay During Edit' in the Program Monitor enables timecode display during the editing process. This feature is critical for editors who need to keep track of precise timings while assembling or trimming clips. By showing the timecode overlay, it provides real-time feedback about the position in the timeline, which is especially useful for syncing audio to video or determining the exact placement of clips within a sequence.

Having this feature active allows editors to reference the exact frame number or duration of clips, facilitating more accurate editing decisions. This is particularly beneficial when working on projects that require synchronization with audio or when adhering to specific timing requirements. Thus, by enabling this option, the editor can maintain a clear understanding of their timeline's flow and make informed adjustments throughout the editing process.
