Build clips sized for TikTok, Reels, Shorts, and paid social without editing software. ## How it works ### Brief the video Describe what you want, or paste a product URL and let Clip Studio AI pull the details. ### AI composes it The agent scripts the video, selects stock visuals, adds captions, voiceover, and transitions. ### Review and adjust Preview the render, then regenerate with a new angle or change the duration and format. ### Export and ship Download in any aspect ratio, ready for TikTok, Reels, Shorts, or any ad platform. ## Benefits - **Prompt to finished video.** Describe the idea and Clip Studio AI writes the script, sources the visuals, adds a voiceover, and renders a complete video — no timeline editing required. - **Smart stock library.** The agent pulls relevant footage and images from a built-in stock library and arranges them to match your script, so every scene has the right visual. - **Captions and voiceover built in.** Every video ships with burned-in captions and an optional AI voiceover, because most short-form video is watched on mute. - **Every aspect ratio.** Render the same idea in 9:16, 1:1, 4:5, and 16:9 so one brief covers TikTok, Reels, Shorts, feeds, and YouTube. ## Formats - 9:16 vertical - 1:1 square - 4:5 portrait - 16:9 landscape ## FAQs ### Do I need video editing software?
