- Drop an image/video containing a near-frontal face to the **Input Image**/**Input Video**.

- Rescale the input to make it best fit the model.
- The final image result will be based on this **Rescaled Face**. Use padding parameters to adjust the background space.
- **Solution to [Error: no face detected!]**: VToonify uses dlib.get_frontal_face_detector but sometimes it fails to detect a face. You can try several times or use other images until a face is detected, then switch back to the original image.
- For video input, further hit the **Rescale Video** button.
- The final video result will be based on this **Rescaled Video**. To avoid overload, video is cut to at most **100/300** frames for CPU/GPU, respectively.
