Example preview
The approved source and a verified replacement example will appear here after media preparation. No sample video is currently published. A model sample does not establish the quality of every result.
Before you begin
What will I upload?
One clear, unobstructed JPG, PNG or WEBP photo, up to 10 MB. PNG must have no transparency. A full-body photo is not required. The source video and editing instructions are fixed.
What will the result look like?
The workflow aims to replace the lead character while retaining the original motion, scene and sound. AI output may change surrounding details; exact identity, lip sync and unchanged backgrounds are not guaranteed.
Can I generate a 15-second video now?
Not yet. The planned 15-second option costs 300 credits and combines two consecutive parts into one video. It will remain unavailable until the complete result and delivery pass acceptance.
How long does it take?
Processing time varies. We do not promise a fixed completion time. The finished studio will show the actual task state.
