4:5 Video for Mobile Feeds
4:5 video is a vertical aspect ratio that uses a taller frame than square while staying narrower than full 9:16. It takes a source clip or image and outputs a mobile-friendly composition for feeds like Instagram, making it useful when you want more height for subjects, captions, or product shots. Vidu helps you resize and test that framing quickly.

What Is a 4:5 Video Format?
A 4:5 video is a vertical-leaning aspect ratio that gives more height than a square frame and less empty space than a full vertical one. It is often used for feed posts, product clips, and creator content when the subject needs to stay clear on mobile screens, and a video cutter can help you trim footage to fit this format cleanly. For teams shaping that framing into polished marketing content, a streamlined video creation workflow can help turn ready assets into campaign-ready clips.
How to Make a 4:5 Video in Vidu
Upload Starting Frame
Open Vidu Image to Video and upload your first image as the starting frame; if you want a transition between two images, add a second image as the ending frame, and use the image enhancement workflow to refine the source visuals before generating.
Set Prompt and Options
Enter a prompt describing the motion you want and explicitly ask for a 4:5 vertical feed composition, then refine the reference-based video setup before creating.
Create and Download
Click Create, wait for Vidu to generate the video, then preview the result and use the image enhancement workflow if the framing and motion need a cleaner finish before you download it to your device.
4:5 Video Format Choice for Mobile Feed Clips
Compare 4:5 against other common frames before turning a clip or image sequence into a mobile-ready Vidu video.
| Decision Area | Vidu Image to Video | Manual Or Generic Workflow |
|---|---|---|
| Frame shape | Set the output to a taller feed-friendly frame that keeps more vertical subject detail than a square. | Keep the clip in its original shape or apply a basic crop without planning for feed proportions. |
| Source composition | Use the starting image and optional ending image to place the subject, text area, and motion path inside the 4:5 canvas. | Resize after the fact and hope the important parts still fit inside the frame. |
| Feed readability | Review whether faces, products, and captions stay clear when viewed in a mobile feed. | Check the video only on a desktop preview, where spacing issues are easier to miss. |
| Crop tolerance | Adjust the framing so top and bottom content do not feel cut off in the final post. | Accept a generic crop that may remove hands, labels, or other edge details. |
Creative Uses for 4:5 Video
Use 4:5 video to shape mobile friendly creative that gives products, people, and messages more presence in tall social feeds without losing visual focus.
Product Reveal Clips
Frame a new item with room for motion, text, and context so shoppers can understand the offer quickly while the product stays visually central.
Creator Promo Cuts
Turn creator led moments into polished feed assets where faces, captions, and brand cues feel balanced within a taller mobile viewing space.
Campaign Teaser Videos
Build compact teaser moments for launches, sales, or announcements that feel native to mobile browsing and make the core message easy to notice.
Readable Creator Overlay Clips
Use 4:5 video drafts to turn creator clips, social posts, or campaign ideas into a mobile-first frame that feels polished enough to judge at a glance. The taller composition gives subjects and overlays more breathing room, so reviewers can quickly see whether the message reads clearly in-feed. A strong first draft helps teams align on creative direction before full production, especially when a supporting scene background needs to reinforce the message without competing in a tall layout.
High-Performing Feed Campaign Cuts
A 4:5 video is ideal for marketing tests because it gives you a clean, mobile-first frame that feels ready for real campaign review. It helps teams judge whether a product shot, creator clip, or promo message reads clearly in feed placement before committing to a full edit. That makes it easier to compare concepts, spot framing issues early, and choose the version most likely to perform well in social channels.
Audience-Ready Mobile Posts
Use 4:5 video review to judge whether the frame feels balanced, the movement supports the message, and the overall look is ready for a mobile feed. If the crop works but the clip needs a clearer visual direction, teams can compare revised versions while keeping the core action in view. This review step makes it easier to turn a rough cut into a confident, audience-ready post.
