Paste a short script. Shot Director plans the shots, StoryFlow draws the cast and the set, every clip is checked by the checking agents (and redone once if it fails), and the editor cuts the film. It runs on your own fal.ai key (Account → API keys) and stops before going over your limit.
Up to about a minute works best.
Estimated cost: about $4.10 with no redos. The run stops before it would go over your limit, and you can raise it and go on.
