# Vertical video, a wider frame. > Generate space to the left and right of a portrait clip. This is useful when a square or vertical source needs a landscape presentation. Source: https://videooutpainting.com/video-outpainting-portrait-to-landscape · Updated: 2026-10-09 · Publisher: Video Outpainting (independent; not affiliated with Lightricks) ## Can AI make a portrait video wider? A video outpainting model can fit a portrait source into a landscape canvas and generate the missing surroundings on either side. You provide the source clip and a description of the background. This release offers 16:9 output for short MP4 footage. Product labels, reflective surfaces and moving subjects still need inspection because generative edits can alter the original region. ## Unbranded bottle: source and outpainted result Play both complete clips. The source is AI-generated footage from our own published library, not a customer case or camera recording. Source clips contain generated audio; the outpainted results are silent. These are individual jobs, not a success-rate benchmark. ### Unbranded bottle · source [Original AI-generated unbranded bottle clip before spatial outpainting](https://videooutpainting.com/media/product-source.mp4) Original 720×1280 source, about 5.04 seconds, 30 fps with generated audio.

They retain the complete frame: no retouching, AI enhancement or concealed cropping. The different frame rates mean this is an approximate time comparison, not a pixel-aligned difference measurement. ### Unbranded bottle · source at approximately 2.5 s ![Full source frame of the unbranded bottle around 2.5 seconds](https://videooutpainting.com/media/product-source-2-5.jpg) Source frame. Use it to inspect the subject, lighting and composition before expansion. - Dimensions: 720 × 1280 ### Unbranded bottle · result at approximately 2.5 s ![Full outpainted unbranded bottle frame around 2.5 seconds](https://videooutpainting.com/media/product-output-2-5.jpg) Result frame. New space and changes inside the supplied image region are both part of the generated output. - Dimensions: 1280 × 704 ## Prepare the source for a wider composition Trim to a single continuous shot of no more than five seconds, then compress below 4 MB. Avoid rapid cuts and camera moves until you have tested a simpler clip. Describe what already surrounds the subject: a dark studio wall, a tabletop, an ocean horizon. Keep lighting direction and perspective in the prompt. Do not promise that a logo or fine lettering will survive unchanged. The product sample returned 1280×704 with a wider dark setting and moving drops. Fine bottle details still need inspection. A completed sample is not a guarantee for other products. Use the source preview and output playback to evaluate your own footage. [Compare outpainting with crop and bars](https://videooutpainting.com/video-outpainting-vs-crop). ## Expand a video in four steps 1. **Open the processing workspace** Use your Wan3Prime account. [Open video outpainting](https://wan3prime.com/video-outpainting). Accounts and credits are shared with its other supported tasks. 2. **Upload a short MP4** Use a trimmed clip up to 5 seconds and 4 MB. The source preview shows its dimensions. Choose a different output shape: landscape or portrait. 3. **Describe the missing surroundings** Describe the background and lighting that should continue outside the frame. Review the fixed 70-credit quote before submitting. If needed, buy credits and return to this workspace. 4. **Review and download** Watch the original and result, inspect the beginning and end for flicker or distorted subjects, then download the silent MP4. Failed processing returns credits automatically. ## Landscape output questions ### Can I make a vertical video horizontal without stretching it? Outpainting fits the source into a wider composition and generates surroundings. It does not rely on stretching as a conventional resize would, but it can still alter detail in the source region. ### Will the subject be exactly centered? The app uses a fixed source-fitting preset and does not expose custom positioning. Inspect the result before designing a layout that depends on exact placement. ### Can the added sides contain accurate text or a logo? This workflow does not promise accurate new lettering. Add approved text and brand assets in an editor after reviewing the silent MP4. ### Can I request a custom ultrawide canvas? Not in this release. The workspace exposes portrait or landscape at one nominal resolution; it does not expose every aspect ratio in the provider API. ## Choose your next step Prepare the file with the [MP4 input guide](https://videooutpainting.com/prepare-mp4-for-video-outpainting), then inspect the [fixed output budget, silent audio and preservation limits](https://videooutpainting.com/video-outpainting-limitations).
