How Cast works
Three taps from idea to video. Cast is built for phones: no app install, and it works inside TikTok's and Instagram's in-app browsers.
Pick who's in it
Start with the free Malfoid & Friends pack (Malfoid, Thea, Odette) or describe your own character in a sentence. Cast draws four looks with Midjourney v8.2 and you tap the one you like (15 credits).
Type one line
Say what happens: "dances on the castle roof at midnight". Optionally pick a style, a camera and a vibe. A language model expands your line into a full shot-by-shot video prompt.
Get the video in your feed
Cast renders a vertical 9:16 clip of 5, 10, 15 seconds with ByteDance Seedance and drops it into your own private, swipeable feed. If a render fails, the credits go straight back.

Every video can take a style, a camera and a vibe. Skip them and Cast picks sensible defaults.
