DRAW THINGS SeedVR2 Image Upscale FREE Mac iPad iOS
Cutscene Artist
Overview
This video tutorial demonstrates how to use the SeedVR2 model within the DrawThings application for Mac, iPad, and iOS. SeedVR2 is a powerful, one-step upscaling model that can enhance image resolution and quality. The tutorial covers downloading and setting up SeedVR2 as a render model, configuring its parameters for optimal results, and a workaround for a common issue where saved presets can interfere with canvas size. It emphasizes that SeedVR2 is not a traditional ESRGAN upscaler and provides specific settings for tiled decoding and diffusion to achieve clean, high-resolution outputs.

Chapters
- SeedVR2 is a one-step AI upscaling model available for DrawThings.
- DrawThings is a free application for Mac, iPad, and iOS that runs AI models locally.
- SeedVR2, despite its name suggesting video restoration, functions as a creative upscaler for single images.
- It can produce clean results on both photography and illustration styles, potentially replacing existing high-resolution fix workflows.
Understanding SeedVR2's capabilities and its integration into DrawThings allows users to enhance their image generation workflow with a powerful, free tool.
Using SeedVR2 as a creative upscaler for single images, potentially rethinking the need for traditional high-res fix methods.
- SeedVR2 is loaded via the model drop-down menu in DrawThings.
- It is crucial to set the render size to a large value and load an image to the canvas.
- Do not use image-to-image mode; keep strength at 100% to avoid original image bleed-through.
- SeedVR2 is not an ESRGAN+ model, so the upscaler drop-down in advanced settings must be set to 'disabled'.
Correctly setting up SeedVR2 as a render model ensures that the upscaling process works as intended, preventing common issues like image degradation or incorrect application of the model.
Loading SeedVR2 in the model drop-down, setting a large render size, and ensuring the upscaler drop-down is disabled.
- SeedVR2 comes in 7B (approx. 8.5GB) and 3B versions, with quantized options for efficiency.
- The 3B version is likely for devices with less than 8GB of RAM.
- Quantized versions (8-bit S for M5/M4, 6-bit for M3 and earlier) optimize performance on lower RAM devices.
- The unlabeled model is also mildly quantized to preserve quality; 7B is recommended for 16GB+ RAM.
Selecting the appropriate model version based on your device's RAM and processor ensures smooth performance and optimal quality without crashing the application.
Users with 16GB of RAM or more should use the 7B version, while those with less RAM might opt for the 3B or quantized versions.
- Enable 'tiled decoding' and set height/width to 1024x1024 with 128 overlap.
- Enable 'Tile Diffusion' and set height/width to 1024x1024 with 128 overlap.
- In the basic menu, set Steps to 1, Guidance to 1.0, Shift to 5.0.
- Use the DPM++2m-trailing sampler for best results.
These specific advanced settings are crucial for SeedVR2 to perform its one-step upscaling effectively, ensuring a clean and detailed output without artifacts.
Enabling tiled decoding and tile diffusion with 1024x1024 dimensions and 128 overlap, alongside specific step, guidance, shift, and sampler settings.
- Save the current configuration using the 'Save Config' option in the context menu.
- Name the saved configuration, e.g., 'SeedVR2'.
- When using tiled diffusion, the interface allows for higher render sizes.
- Rescale the canvas to 200% or copy/paste the image into a resized canvas before generating.
Saving configurations allows for quick recall of optimal settings, streamlining the upscaling process for future use.
Saving the current settings as 'SeedVR2' and then rescaling the canvas to 200% to accommodate a larger output size.
- Loading a saved config can overwrite the current canvas size, causing inconvenience.
- This issue can be fixed by editing the `custom_config.json` file.
- On Mac, the file is located in `~/Library/Containers/Draw Things/Data/Documents/Models/`.
- Delete the 'width' and 'height' lines from the specific config entry within the JSON file to prevent it from overriding canvas dimensions.
This workaround resolves an annoying conflict, allowing saved presets to load all parameters except canvas size, thus maintaining workflow flexibility.
Editing the `custom_config.json` file to remove the 'width' and 'height' lines associated with the saved 'SeedVR2' preset.
Key takeaways
- SeedVR2 is a powerful, free, one-step upscaling model for DrawThings that enhances image resolution.
- Proper setup involves loading it as a render model and disabling traditional upscaler options.
- Choosing the correct model version (7B, 3B, or quantized) is essential for performance based on device RAM.
- Advanced settings like tiled decoding and tile diffusion, with specific parameters, are key to achieving high-quality results.
- Saving configurations streamlines the workflow, but a manual edit of `custom_config.json` is needed to prevent canvas size conflicts.
- DrawThings enables local AI model processing without subscriptions on Apple devices.
