Most timelines lose a chunk of editor time to the same chore: drop the chat overlay onto V2, scale it, drag it to the right spot, repeat for every clip. The timeline maker moves that step into the browser. Each clip that has a rendered chat overlay gets a small preview canvas with a draggable ghost rectangle so you can decide where chat sits inside the frame.
That position is written straight into the project file as the V2 clip's transform. When DaVinci opens the FCPXML the chat overlay is already where you parked it. No extra fiddling, no per-clip nudging inside the editor that ate your evening last time.
