Uploading your source video

Formats and size

Drag in an MP4, MOV, or WebM up to 200 MB. The file uploads straight to storage over a signed link, so a big clip never has to squeeze through a form, and the progress bar stays cancellable the whole time it transfers.

Upload the clip inside the project you are actually working in. The clone reads that project's reference pack to find the product it swaps in, so a project-scoped upload is the thing that makes every later step work. Drop a video into the wrong project and the swap has nothing to pull from.

The real-person rule, read this first

Before you upload anything, know this one limit. The provider runs moderation on your source video, and if it sees a real person on camera it refuses the clip before it renders a single frame. This is a rule about the input, not a glitch, and no setting or clever wording gets around it.

When a clip is refused, the run drops back to a styled first-frame path that will not match the reference's motion, and the result is flagged so you are never fooled about what you are looking at. The practical upshot: you cannot clone a competitor's UGC ad that has a real face in it. Use footage with no recognizable real person, or your own footage where you hold the rights.

The script it writes for you

The moment the upload lands, the tool transcribes the spoken audio so you can see and edit exactly what the clone will say. Leave it untouched to keep the reference's own message. Editing it is covered in the style and script lesson.
