You have a series of video clips stacked on V1, 2, 3,4, and 5. Each clip also has synced audio on the timeline. How can you add an edit point to all clips simultaneously?

The most direct and efficient method to add an edit point (a cut) across all unlocked tracks simultaneously is by using the Razor tool with a modifier key. By selecting the Razor tool (keyboard shortcut 'C') and then holding down the Shift key while clicking on the timeline, Premiere Pro will create a cut that extends vertically through every clip on every unlocked video and audio track at that specific point in time. This single action accomplishes the goal precisely as described.

A. The menu path is incorrect. The "Add Edit" command is located under the Sequence menu, not Clip > Edit.
B. The right-click context menu for a selection of clips does not contain an "Add Edit Point" or "Add Edit" command.
D. This is not a real preference setting. There is no such option within Edit > Preferences > Timeline in Adobe Premiere Pro.

"Split or cut one or more clips" section.

Under the subsection "Split clips using the Razor tool

" the documentation states: "To split all clips on all tracks at a specific point

select the Razor tool and Shift-click at that point." This directly confirms that holding Shift with the Razor tool performs a "through edit."

2. Adobe Premiere Pro User Guide

"Default keyboard shortcuts in Premiere Pro" section.

The documentation for the Razor tool (C) describes its basic function. The modification of this tool's behavior with the Shift key is a core feature. The alternative keyboard shortcut Control+Shift+K (Windows) or Command+Shift+K (macOS) performs a similar function ("Add Edit to All Tracks")

but the method described in option C is the correct one involving the Razor tool itself.
