## Use a first frame

Pass **1** input image for image-to-video. The image becomes the opening frame. URLs or uploaded files both work. See [Upload input images](/guides/upload-input-images).

```bash REST API theme={"theme":"kanagawa-dragon"}
curl https://api.mynth.io/video/generate \
  -X POST \
  -H "Authorization: Bearer $MYNTH_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Slow push-in as the lantern sways in a night breeze",
    "model": "xai/grok-imagine-video-1.5",
    "inputs": [
      {
        "type": "image",
        "source": { "type": "url", "url": "https://example.com/input-image.jpg" }
      }
    ],
    "resolution": "720p",
