How much does it cost?

It depends on the model and the settings, and the exact price is on the Generate button before you start. The lowest here is Grok Imagine 1.5 Lite: from 1.5 credits per second. A clip that fails costs nothing: its credits come back automatically.

Can I try it for free?

Yes. Every new account gets 10 free credits to start on the fast models, with no card, and every model comes with a 3-day free trial. The free credits make a clip of up to 5 seconds with Grok Imagine 1.5 Lite.

Whose photos can I use?

Only photos you have the right to use, and never to make someone appear to do what they did not. See the Acceptable Use Policy.

Can I post it on TikTok or Reels?

Yes, within the model makers’ terms and our Terms of Service. Pick 9:16 under Aspect ratio where the model offers it, and switch on TikTok’s AI-generated label when the clip looks real.

Free AI Halloween video generator

Add a photo and describe the Halloween scene around the people or the pet in it: a costume, a porch lit by pumpkins, fog rolling in, a slow push-in on a grin. Grok Imagine 1.5 Lite starts from your photo as the first frame, so faces, clothes and poses stay as they were. The free credits make a clip of up to 5 seconds with it. The 3-day free trial opens Kling 3.0, Gemini Omni Flash and Grok Imagine 1.5, which also take a photo to start from.

How it works

Open the Video page with Grok Imagine 1.5 Lite picked, and add your photo as the start frame.
Describe what changes and how it moves: "a skeleton costume appears on him, fog rolls across the floor, candles flicker, the camera pushes in slowly".
Pick 5 seconds to start. The price is on the Generate button.
Generate. A failed run costs nothing, and the clip is kept in Assets with no watermark.

Tips

Use a sharp, well-lit photo with the faces clearly visible: a dark photo loses detail once the scene turns spooky.
Change one thing at a time, the costume, the place or the light, so faces stay recognisable.
Leave out film characters and famous masks: models turn down results that look like existing work.
