2What it means for delivery
An upscale or export step is honest about where the pixels come from. It suits a 4K deliverable whose clips were generated at 1080p or 720p, and the sheet records the generation figure beside it wherever the vendor prints one.

An AI short drama is a serialized show of 60–120 second vertical episodes whose cast, sets and footage are generated by AI. Making one takes six steps: analyze the script into episodes, lock a consistent cast with reference art, localize for your market, write and edit storyboards, generate each 4–15 second shot, then composite and publish.
