Create and Edit Vertical Video for Mobile
Vertical video is a portrait-format video made for mobile-first viewing, usually with a 9:16 frame that keeps the subject, captions, and motion readable on small screens. It takes source footage or a prompt and outputs a draft for TikTok, Instagram Reels, or YouTube Shorts. Vidu helps you plan and test that format.
What Is Vertical Video?
Vertical video uses a portrait frame where height is greater than width. It is built for mobile viewing and short-form platforms. Vidu helps creators shape vertical drafts with framing, editing, and review steps that keep the result easy to judge.
How to Use Vertical Video
Add Reference Images
Click +reference and upload 1 to 7 reference images, or choose images from the RefHub library or your own saved references, so Vidu can keep the subject consistent as you build vertical clips from your source video.
Set Prompt and Options
Describe what the character or object should do, then choose settings such as resolution, aspect ratio, model, generation mode, output length, motion amplitude, and audio if needed. For tighter vertical edits, plan the framing before generation and save detailed timing adjustments for after the shot is created.
Create and Download
Click Create and preview the vertical video. If the clip includes spoken lines, use AI lip sync checks to review mouth movement and timing before downloading the final version.
Vertical Video Fit Guide
Vertical video is strongest when the frame needs to feel immediate, personal, and mobile friendly. This guide helps you judge whether your idea, source material, and audience goals align with a portrait format before production begins.
Portrait Story Focus
Choose a tall frame when the main subject should hold attention without competing background detail. It works especially well for faces, gestures, and emotionally direct moments that benefit from a centered composition and minimal background detail.

| Decision Area | Vidu Reference to Video | Manual Or Generic Workflow |
|---|---|---|
| Source Material Setup | Upload 1 to 7 reference images to anchor the subject, scene, or object before generating. | Build the clip from scratch with separate assets, shot notes, and editing prep. |
| Portrait Frame Control | Select 9:16 during creation so the output is framed for mobile viewing from the start. | Crop or reframe later in the editor after the scene has already been built. |
| Motion And Action Direction | Describe what the character or object should do in the prompt to guide the generated movement. | Animate movement by cutting, keyframing, or compositing each action manually. |
| Visual Consistency | Use reference images to keep the subject and scene aligned across the clip. | Match appearance by reusing assets and adjusting each shot by hand. |
| Output Style Choice | Pick a generation mode such as fast, cinematic, or marketing-focused to shape the draft. | Choose a style through editing presets or custom treatment after production begins. |
Vertical Video Use Cases
Use vertical video when speed to a useful first draft matters, and refine it later with a video remaker.
