One face goes in. The clip is square, the model duration is 10 seconds, and the reference sound is attached afterward.

## Questions

### Can I use a pet or a group photo?

A pet can use the one face slot. A group photo cannot.

### How long is the clip and does it have sound?

The duration field is 10 seconds and the frame is square. The reference clip’s sound is attached after the picture is made. A new voice is not generated.

### Is it allowed to post the clip?

Only if you have permission to use that face. The text check does not review the photo or the video.
