- Will the same person appear across several clips?
- No, and this is the most important thing to know before you plan around it. Every generation produces a new person from your description, so two clips from the same prompt give you two similar-looking but different people. There is no character memory and no way to lock a face here. If you need one consistent presenter across a campaign, this is the wrong tool — use an avatar product built for that, or shoot the person once and use image-to-video from a still.
- Do they speak? Can I put a script in their mouth?
- They will move as though speaking if you describe them speaking, and audio is generated with the clip, but this is not lip-sync to a script you supply. The words are not yours and will not match a voiceover you lay over the top. For footage where the specific words matter, generate the visual here and either replace the audio and cut around the mouth, or use a lip-sync tool with a track you control.
- Can I generate a real, named person?
- No, and we would refuse to build a page that implied otherwise. The model renders a person matching your description, not a specific individual it has never seen, and generating a real named person for advertising raises rights and likeness problems that no output quality would fix. Describe the role you need cast, not the person you have in mind.
- How long is each clip and what resolution?
- Between 4 and 15 seconds per generation, at 480p or 720p, in 9:16, 16:9, 1:1, 4:3, 3:4 or 21:9. Cost scales with duration and resolution, and 480p runs at roughly half the credit rate of 720p — worth using while you are still deciding who is in the shot and what they are doing. Set the aspect ratio before generating rather than cropping afterwards.
- Is it free?
- Generating requires a paid plan — Creator or higher. The Free plan does not include tool generation. Each render draws credits based on the duration and resolution you select, and the cost is shown before you run it. Output can be handed straight into the Creatives canvas to be cut, captioned and pushed to your ad platforms.
