Errors occur when a model file is missing to process an image or when the AI engine is not able to run on the computer. 

Missing model alerts can occur after installation or when models don't pass verification after updates. Errors can happen if antivirus, firewall, or a VPN blocks the installer from installing the files.

Disable any of the above security software, then run the Topaz Gigapixel installer again to repair your installation and add any missing model files.

Solutions To Model Downloads

Processing errors are usually a symptom of compatibility conflicts. These issues can appear as explicit processing error alerts or subtle stalling analysis.

Enure that your computer meets the system requirements.

If your graphics card does not meet the system requirements, but your CPU is powerful enough for core model enhancements, switch to CPU processing. 

Launch Topaz Gigapixel
In the menu, select Preferences
Navigate to Settings > General > AI processor, and select CPU

Errors

Gigapixel supports importing and exporting common image formats. 

We recommend using a standardized RGB color space with a common color profile such as sRGB, Adobe RGB, or ProPhoto. 

File Import

Render Export

The following formats will import, but may show color inconsistencies depending on profile and bit depths: 

Imported DNG & RAW files will be exported as TIFF if 

Support for CMYK output is only compatible as a TIFF export.

Depending on the image source, we recommend choosing the option to 

 with or without adjustments. The format you choose in the File Format menu will be the format that Gigapixel exports and returns to Lightroom Classic.

, the Cloud render queue is used to monitor your image status.

Use the refresh button if renders appear stuck

Use the folder icon to navigate to the downloaded image

Use the A|B button to compare in the cloud

Use the ••• button to gather the request ID for support

We recommend using JPEG files with Cloud Rendering

, confirm that its format (encoder/wrapper), and colorspace are in the supported list above.

If you see strange color shifts in the preview

, the color space or color profile of your image may not be directly supported and should be converted before importing.

If you're attempting to import an image that is already very large

, you may not see the 4x or 6x scale factors in the Upscale section. This is because upscaling with those factors would exceed the maximum pixel dimension of 32,000px.

For large upscales, 24GB of RAM or more may be needed

If an image source came from scanners, screen captures, or somewhere online; it may have the issue of false resolution. False resolution happens when an image is upsampled, boosting pixel count without adding real detail. The image source may have large dimensions, but the extra pixels are interpolated and don’t reflect true information from the original image. Downscaling removes excess pixels and condenses real detail, restoring clarity by eliminating false resolution.

False resolution can easily be recognized by viewing the original image at 

. If you’re seeing blocks of compression artifacts, visible pixel stepping, or artifacts in areas that should otherwise be smooth; it is likely that your image suffers from false resolution and needs to be downscaled before being upscaled in Gigapixel.

Before upscaling, try applying a 1x scale factor to the image using Recover v2 and either Low, Medium, or High pre-downscaling applied.

Depending on the dimensions and quality of the source image, there might not be enough information for the AI models to work with, so the results display made-up detail to complete the upscaling task. Since we can imagine what the scene 

 look like in reality, these AI results appear unnatural. Some images simply aren't good candidates for outstanding results.

Depending on the contents of the image, some models with a mix of settings will perform better than others. Using the Compare (https://docs.topazlabs.com/gigapixel-ai/functions/compare) tool is the best way to experiment with possible results. We always recommend starting with Auto mode (https://docs.topazlabs.com/gigapixel-ai/functions/auto-mode) applied to any image and adjusting from there.
