Image Upscaling

Increase image resolution using AI upscaling models. Enhance low-resolution images, upscale generated images, or prepare images for print.

How to Upscale Images Inside Chat Video Pro

How It Works

1. Have an image - Generated image or uploaded image

2. Click the "Transform" button - On the image thumbnail

3. Select upscaling model - Choose Topaz, Recraft, or Sima

4. Set scale factor - 1.5×, 2×, 3×, or 4× (varies by model)

5. Configure settings - Model-specific options

6. Upscale - Click to start upscaling

7. Get result - Higher resolution image

Natural Language Upscaling

You can also upscale using natural language:

• "Upscale this image" - Automatically uses Recraft Crisp Upscale

• "Enhance the quality" - Upscales the image

• "Make this higher resolution" - Increases resolution

The AI automatically detects your intent and routes to upscaling.

Scale Factor Guidelines

1.5× Upscaling

Use when:

• Slight resolution increase needed

• Quick enhancement

• Maintaining file size

• Minor quality boost

2× Upscaling

Use when:

• Standard upscaling

• Doubling resolution

• Most common use case

• Good balance

3× Upscaling

Use when:

• Significant resolution increase

• Preparing for large displays

• High-quality output needed

• More processing time

4× Upscaling

Use when:

• Maximum upscaling

• Very low-res source images

• Print preparation

• Maximum quality needed

Tips for Best Results

1. Start with a quality source - Better input = better output

2. Choose an appropriate model - Topaz for quality, Recraft for speed

3. Match scale to needs - Don't over-upscale unnecessarily

4. Use face enhancement - For portraits, enable face enhancement

5. Consider output format - PNG for quality, JPEG for size

6. Test different models - Some work better for specific image types

7. Iterate if needed - Can upscale multiple times if needed

Troubleshooting

"Upscaling is too slow."

Solutions:

• Use Recraft Crisp for faster results

• Lower scale factor (2× instead of 4×)

• Smaller images upscale faster

• Check the internet connection

"Quality not improved enough."

Solutions:

• Use Topaz "High Fidelity V2" model

• Try a higher scale factor

• Ensure the source image is of good quality

• Try a different model (Sima for details)

"Faces look distorted."

Solutions:

• Enable face enhancement (Topaz)

• Use a lower scale factor

• Try the "High Fidelity V2" model

• Check source image quality

"Upscaling not available."

Solutions:

• Ensure you have an image attached

• Clickthe "Transform" button on the image

• Check that upscaling models are available

• Verify API keys are configured
