Generate an 8-10 second video prompt for a hand-drawn fantasy action animation. Build it as a reusable video brief with three concrete beats: open on a sketchbook-style world with the main character, magical prop, and immediate danger clearly framed; move into a fast but readable action beat such as a leap, spell burst, creature dodge, or sword-spark clash; end on a stable illustrated hero frame with the character, motion trail, and fantasy environment still editable. Keep the whimsical drawing style grounded through clear silhouettes, consistent character scale, controlled camera motion, visible linework, and color accents that do not overwhelm the action. Specify pacing, camera distance, lens feel, paper texture, smear frames, motion blur, and continuity rules so the animation reads as intentional hand-drawn motion. Keep characters, props, creatures, setting, text, and logo areas editable. Avoid real franchises, celebrity likenesses, fixed IP, unreadable signs, unsafe realism, sudden teleport cuts, warped anatomy, inconsistent costume details, and random symbols that distract from the fantasy action.
