Two more things stop dying with the generation that created them.
Your voice. If you’ve trained a voice clone in the Studio, hit Use voice on it in the Library and it becomes your sticky narrator: every video you make from then on speaks in that voice — narration, per-speaker fallbacks, the works — until you clear the chip in the composer. Explicitly pinned voices are honored strictly: if the voice ever becomes unavailable, generation stops and tells you rather than quietly swapping in a stock voice.
Your look. When a static ad comes out right, the gallery now shows Save style. One tap clones the full visual DNA the plan actually used — palette, typography, composition, texture — into a private style owned by your workspace. It appears in a new My styles section of the style picker, ready to pin on the next campaign, and it’s yours alone: saved styles never show up for other workspaces and never enter the automatic ranker.
