AI VIDEO CHARACTER & OBJECT SWAPS
Swap characters, products, or clothes.
Keep the scene. Make it yours.
Video templates
Explore short clips for character, product, and outfit swaps in the editor.
Your video. A different character, product, or outfit.
StirVid edits existing videos with Higgsfield Genjutsu. Choose a template or upload a 4–30-second camera-roll video, add reference images, and describe what should change. The source video guides the performance and scene.
Three steps to a video swap
- Choose your scene. Upload your own clip or select a template. Preview it before choosing the subject to replace.
- Link your references. Add 1–8 images and type @ in the prompt to link your video and replacement images. Describe each subject by appearance, action, or position.
- Check the price and generate. Choose 480p or 720p, review your total, then pay per video. No account or subscription is required.
AI results vary with the clip and references. Clear subjects and simple instructions help; rapid cuts and hidden objects can make a swap less predictable. Confirmed failed generations receive an automatic refund.
Questions before your first swap
How can I swap characters in my video?
Open StirVid, upload your video, and add an image of the replacement character. In the prompt, identify the person to replace and link the uploaded assets, for example: replace the dancer on the left in @video1 with the character in @image1. Review the price and generate your swap.
Can I replace more than one person or object?
Yes. Attach a reference image for each replacement and describe each target separately by position, clothing, or action. For example, replace the person on the left with @image1 and the bag on the table with @image2. Complex scenes can produce less consistent results.
What can I upload?
Use a camera-roll video (MP4, MOV, M4V, or WebM) between 4 and 30 seconds, up to 50 MB. Add up to eight JPG, PNG or WebP reference images, up to 10 MB each.
How do I get a better swap?
Use a sharp clip with a clearly visible subject and well-lit reference images. Describe what to replace using @video1 and @image1. Fast cuts and obstructions can make results less predictable.
Do I need an account?
No. Upload, choose the quality, and pay for one video. You can save your purchase to an account afterward.
Can I leave while it generates?
Yes. We email a private purchase link after payment. Open it to check progress and download your video. Purchases also appear in My swaps in the original browser.
What happens if a swap fails?
Confirmed failed, canceled, or provider-declined paid generations are refunded to the original payment method. Uncertain submissions need review before retrying or refunding.
Who can see my uploads?
Uploads are private to your guest session or account. Anyone with a purchase recovery link can access that purchase, so keep it private. Higgsfield processes the media to create your swap.
How do I pay?
Pay for each video with Apple Pay, Google Pay, or card where supported. Your exact total appears before payment. No subscription or credit balance is needed.
