Mid-Roll Manager от Nick Vogel

Mid-Roll Manager lets you bulk-insert and clean up mid-roll ad slots in the Studio monetization editor. Place ad slots at regular intervals with one click, then clean up redundant or too-close placements automatically. The extension reads all existing ad slots, filters out manual slots that are too close together (based on a configurable minimum interval), respects automatic ad slots, and removes the rest. Both insert and cleanup support dry-run mode so you can preview changes before committing. Configurable speed settings let you tune performance for your hardware.
