Source-led movement

THE SCENE IS YOUR STARTING POINT
What AI Character Swap Keeps From Your Video
Source-guided scene
The model uses your camera framing and background as a guide. It can redraw nearby people, clothing and scenery; it does not preserve every original pixel.
Keep the original audio
The model is requested to retain the source audio. Audio and lip-sync quality still need review in the final result.

AI Character Swap FAQ
How do people make AI character swap videos?
They give a video replacement model a character photo and a source clip. The model rebuilds the person while following the original performance, camera and timing.
Is this a face swap?
Character replacement can change the person beyond their face, including appearance and clothing. It uses the full video as a motion reference.
Can I keep the original sound?
The request keeps the source audio enabled. Use audio you have permission to reuse, and review synchronization in the result.
Which files can I upload?
One JPG, PNG or WebP photo up to 10 MB, and one H.264 MP4 from 1 to 15 seconds, up to 25 MB, with neither side above 1920 pixels.
Can I replace a person in a long video or music video?
Use a clip you have permission to edit, including its audio. Trim it to 1–15 seconds before uploading. Full-length music videos and multi-minute videos are not supported. A continuous shot with one clearly visible adult is the best fit.
How long does it take, and can I leave the page?
Allow roughly 2–5 minutes after submission; queues and safety checks can take longer. Keep the page open during upload and submission. Once the request is saved, processing continues in the background. Sign in with the same account and open My videos to check progress and download the result.
Is there a faster quality tier?
Both packs use the same 720p processing setting. Buying more credits does not increase priority or speed. There is currently no separate faster or higher-quality tier. Exact output dimensions and visual quality can vary with the source clip.
Is there a free trial or subscription?
There is no free generation trial and no subscription. Choose Single Video for $4.99 or 3-Video Pack for $12.99. Buy video credits before you generate.
Can I use anyone’s photo?
Use yourself, a consenting adult or an original adult character, and clips and audio you have permission to edit. Do not impersonate people or make deceptive political content. No sexual content or minors.
What if a render fails?
A confirmed technical failure returns the video credit; a moderation block does not cost a credit. This is a credit return, not a card refund. An unclear provider result stays under review with the credit reserved—do not resubmit it. A completed result you dislike does not include a free retry or refund.
Can I request a payment refund?
Contact Support within 14 days of purchase if none of the credits in the pack have been used. Approved payment refunds go to the original payment method. Used credits are not refundable, except where mandatory consumer rights apply. See the Refund Policy for the full terms.
How are my files handled?
Files are private. Local drafts expire after 30 minutes. Uploaded inputs are kept for up to 24 hours and results for 6 days. Pruna processes the inputs; SeeAPI reviews inputs and outputs.
