Gigpixel processes the image forever

Topaz Gigapixel AI Bugs and Issues

The title says it all. I upgraded to the latest version. An image is processed 10 min now and then I just stop… Does not work. Any ideas?

Troubleshooting Gigapixel AI Stalling During Export

If Gigapixel AI stalls during export, it’s usually because your computer has run out of resources (RAM or VRAM). Follow these steps to troubleshoot:

1. Check System Requirements

Make sure your system meets or exceeds the minimum requirements, especially for resource-heavy tasks. Refer to the system requirements for more details.

2. Selecting the AI Processor

To optimize performance, you can select which AI processor Gigapixel AI uses for processing. This can help if your computer has multiple GPUs or if you want to ensure the best hardware is being utilized.

  • Open the Preferences Panel:

    • Mac: Click on the Gigapixel AI menu, then choose Preferences.
    • Windows: Go to Edit in the main menu and select Settings.

  • Change the AI Processor:

    • In the Preferences window, under the General tab, you’ll find a setting called AI Processor. You can choose between your CPU or GPU for processing. If your computer has a powerful GPU, selecting it will significantly speed up image upscaling.
    • Gigapixel AI generally selects the best available processor by default, but if you have multiple GPUs or an integrated GPU, manually choosing the better-performing option can help optimize processing time.

3. Handling Large Files and Resource Usage

Gigapixel AI is primarily designed to enhance smaller, low-quality images, making them suitable for printing, web use, etc… However, applying models to larger files—such as RAW images from high-res cameras or large TIFFs—can be extremely resource-intensive, even for powerful systems. Here are some scenarios to consider:

  • Enhancing Large Files: Running models on large, high-resolution files (RAW or TIFF) requires significant resources. Gigapixel is optimized for smaller images, so enhancing very large files increases the risk of overwhelming system resources. If you’re frequently working with large images or RAW captures, consider using Topaz Photo AI, which is better suited for such workflows.
  • Large Upscales: Upscaling high-res images by large factors, like 6X, significantly increases system strain. Larger upscales require more resources, so starting with a big file and attempting a large upscale will be far more demanding than a smaller upscale, like 2X or 4X. Reducing the upscale factor or using a simpler model can help manage resource usage.
  • Large Exports: Exporting large images is resource-intensive, especially with minimal compression or high bit depths. For example, exporting a 6X upscaled image as a TIFF with high bit depth and minimal compression will require significantly more resources than exporting as a JPEG with default compression. To reduce strain, consider adjusting compression settings or bit depth—JPEG, TIFF, and PNG formats all allow for these adjustments. Opting for lower bit depths, higher compression, or more efficient formats like JPEG can help manage resource usage and prevent stalling.

3. Using Resource-Intensive Models

  • AI Model Selection: Different AI models are optimized for different types of images. For example, certain models like High Fidelity or Low Resolution might struggle with specific image characteristics where the Standard model works better. Choosing the right model based on your image type can help reduce stalling and improve results. For more information on model selection, refer to the AI Models Guide.
  • Recovery Model: The Recovery model is in beta and highly resource-intensive. You need at least 6GB of VRAM, and 8GB is highly recommended, even for images under 1000x1000 pixels. Using larger images will almost certainly cause stalling or very slow exports depending on your machine’s capabilities. For more details, refer to the Recovery FAQs.

4. Potential Bugs or Memory Leaks

If none of the above solutions resolve the issue, you may have encountered a bug or memory leak. In this case, you can:

  • Send Your Logs and System Profile: Contact us at help@topazlabs.com with your Gigapixel logs and system profile so we can investigate. Here’s how to gather that information:

    • To Get Your Logs:
      • Open Gigapixel.
      • Go to the Help menu and select “Open Log Folder.”
      • In the Logs folder, select all files, right-click, and choose “Compress” to create a .zip file.
      • Attach the .zip file to your email.
    • To Get Your System Profile:

    Attach your system profile along with the logs in the same email.

  • Try Downgrading Gigapixel: You can also try downgrading to an older version of Gigapixel to see if the issue persists. Installers for previous versions are available in the Gigapixel AI Community.
