Tips

Create a character once, reuse everywhere. Generate a Soul character image, then use it as a reference for video models (image-to-video) across multiple scenes.
Style presets are powerful. Each preset dramatically changes the aesthetic. Experiment with different styles for the same character.
Batch generation (2 or 4 images) gives you options to pick the best result at the same per-image cost.
Portrait (9:16) is ideal for talking head videos and social media content.

Composition example

Create a character and animate them across scenes:

const character = Image({
  model: varg.imageModel("soul"),
  prompt: "young woman, professional, confident, modern office background",
  aspectRatio: "9:16",
  providerOptions: { varg: { styleId: "REALISTIC" } },
})

// Animate the character
const video = Video({
  model: varg.videoModel("kling-v3"),
  prompt: { text: "she turns and walks toward the camera", images: [character] },
  duration: 5,
})
