Read the deck's delivery class.

Returns the class the finish delivers the deck at: deliveryResolution (720p unless the writer chose 1080p — the plan never raises it), isDefault (true when nobody chose on the deck, so the 720p default applies — say so rather than reporting the default as a decision), renderResolution (every take renders at 480p first, whatever the class), options, editable (false while a render or finish pass is running), and finishCredits (what finishing this deck costs at each class, in Studio Credits; say this number, never a dollar figure). Raising the class upscales the selected takes at finish: it quotes a finish, never a render. Scope: story:read.
