## Workflow Integration

### Image Generation + Upscale

```
[Prompt Node] → [Model Node (Flux 2 Pro @ 2K)] → [Upscale Node (Recraft)] → [Export]
```

Generate images at 2K and upscale to 4K.

***

### Batch Upscaling

```
[List Node (10 images)] → [Upscale Node (Recraft)] → [Bulk Export]
```

Upscale multiple images in parallel.

***

### Multi-Resolution Output

```
[Image Upload] → [Upscale (Recraft @ 4x)] → [Export @ 4K]
               → [No Upscale] → [Export @ 1K]
               → [Upscale (Topaz @ 4x)] → [Export @ 4K Premium]
```

Generate multiple resolution outputs from one source.

</Tip>

<Tip>
  **Print Quality:** Use Topaz Pro for any print materials to ensure maximum detail preservation.
</Tip>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Upscaled image looks soft/blurry">
    * Try Topaz Pro instead of Recraft Crisp
    * Check source image quality (upscaling can't fix blurry originals)
    * Avoid upscaling heavily compressed images
    * Start with highest quality source possible
  </Accordion>

  <Accordion title="File size too large">
    * Large file size is expected (4x resolution)
    * Compress after upscaling if needed
    * Use JPG for photos (smaller than PNG)
    * Consider if 4x upscale is necessary (2x may suffice)
  </Accordion>

  <Accordion title="Upload fails">
    * Check file size (max 4MP for Recraft, 16MP for Topaz)
    * Resize image if too large
    * Ensure format is supported (JPG, PNG, WebP)
    * Check internet connection
  </Accordion>

  <Accordion title="Artifacts or noise in result">
    * Source image may have noise or compression artifacts
    * Try noise reduction before upscaling
    * Use Topaz Pro for better artifact handling
    * Check if source image is too compressed
  </Accordion>
</AccordionGroup>

## Best Practices

<AccordionGroup>
  <Accordion title="Choose the Right Model">
    * **Recraft Crisp** for most use cases (1 credit, fast)
    * **Topaz Pro** when quality matters most (3 credits, premium)
    * **Recraft** for batch processing (cost-effective)
    * **Topaz** for print or professional work
  </Accordion>

  <Accordion title="Input Image Quality">
    * Start with highest quality source possible
    * Avoid upscaling already-compressed images
    * Sharp, well-lit images upscale better
    * Remove noise before upscaling if possible
  </Accordion>

  <Accordion title="Resolution Limits">
    * **Recraft:** Max 4MP input (e.g., 2048×2048)
    * **Topaz:** Max 16MP input (e.g., 4096×4096)
    * Resize large images before uploading
  </Accordion>

  <Accordion title="File Formats">
    * Use PNG for graphics, logos, screenshots
    * Use JPG for photos, art
    * Avoid heavily compressed files
  </Accordion>
</AccordionGroup>
