Write an AI video prompt that turns an image of your AI persona into a clip: what happens, the line they say, the camera move, the light, the mood and the sound. It is for anyone making talking clips of an AI influencer with Gemini Omni 1.1 Flash or Grok Imagine Video 1.5, and it checks that your line fits the clip.

Randomize changes the action, camera, light, mood and tone. Your line stays as you typed it.
Say what is in the start image, pick what happens, and type the line your persona says, if any.
Choose the camera move, light, mood, sound, model and length. Randomize tries new picks and keeps your line.
Copy the prompt and attach the start image in your video tool. Set the model, shape and length shown under the prompt.
A clip prompt starts from an image and adds what the image can’t show: movement, sound and time.
The video model takes the face from the first frame. A clip looks like your persona only when that image does, so make the image first and check it.
| Model | Length | Shape |
|---|---|---|
| Gemini Omni 1.1 Flash | 3 to 10 seconds, with sound | 9:16 or 16:9 |
| Grok Imagine Video 1.5 | Up to 15 seconds | From one image, the image’s shape |
Some providers offer fewer lengths for the same model, such as 4, 6, 8 or 10 seconds. At a relaxed pace people say about 150 words a minute, roughly 2.5 words a second, so a 6 second clip fits a line of about 12 words with a breath at the end.
Make each clip’s image from your AI persona’s photo, then its video from that image, on your own API keys with Gemini Omni or Grok Imagine. How making videos works →
Write the exact line in quotes in the video prompt, and use a model that makes sound with the video, such as Gemini Omni or Grok Imagine Video 1.5. Start from a sharp image of the persona facing the camera. Keep the line short enough for the clip; the tool warns you when it isn’t.
About 2.5 words a second, a relaxed talking pace, with half a second free at the end. A 6 second clip fits about 12 words. The tool counts your words and warns you when the line is longer than the clip.
The model builds every frame from the first one, so small changes add up. Start from a sharp image where the face is clear, keep the action small and the clip short. If it still drifts, make the clip again from the same image.
Consistent Character Prompt Generator →Yes. For a Reel or a Story, make the start image 9:16, the shape Meta lists for both. The first frame sets what the clip shows, and Grok Imagine takes the video’s shape from the image.
Yes. Gemini Omni makes the audio with the video, and Grok Imagine Video 1.5 makes sound too. Describe what you want to hear in the prompt; the Sound pick does that for you.
Yes, when the video looks real. Meta requires its AI label when you post a photorealistic video or realistic-sounding audio that was digitally created or altered, and it may apply penalties if you don’t.
