How to make a model work for a custom resolution

[Xelvoren]

So in Upscayl app we can set a custom upscaling resolution but how do we do that for upscayl-ncnn? I'm using upscayl-ncnn to automate video upscaling with that code and I'd like to learn how to use it to upscale to a custom resolution. My goal is to upscale 720p to 1080p.

Hello @Xelvoren! I'm here to help you with any bugs, questions, or contributions you may have. Let's tackle this issue together.

To set a custom resolution in upscayl-ncnn, you can use the "CUSTOM_INPUT_RESOLUTION" setting. This allows you to specify a custom output width for the image, and the height will be automatically adjusted. Enabling this option will override the default scale settings. Here's an example of how this setting is configured:

{
  "CUSTOM_INPUT_RESOLUTION": {
    "TITLE": "カスタム出力幅",
    "RESTART": "再起動が必要",
    "DESCRIPTION": "出力画像のカスタム幅を使用します。高さは自動的に調整されます。これを有効にすると、スケール設定が上書きされます。"
  }
}

This configuration allows you to upscale from 720p to 1080p by setting the desired width, and the height will be adjusted accordingly ^[1].

@dosu how can i set it to 1080p?

To set the resolution to 1080p using upscayl-ncnn, you would typically need to specify the desired width for the output image. Since you want to upscale from 720p to 1080p, you should set the custom width to 1920 pixels, as 1080p corresponds to a resolution of 1920x1080.

If you are using command-line arguments, you would use the useCustomWidth flag and set the customWidth parameter to 1920. Unfortunately, I don't have the exact command-line syntax for upscayl-ncnn, but you would generally pass these parameters when executing the upscaling process.

If you are using a configuration file like en.json, you would set the custom width under the "CUSTOM_INPUT_RESOLUTION" section to 1920. Make sure to restart the application for the changes to take effect.

@dosu it did not work. it still outputs at 4x resolution.

The issue might be related to how the custom resolution settings are being applied. Since the upscayl-bin package doesn't include a configuration file by default, and the en.json file is typically used for localization rather than configuration, the custom resolution settings might not be applied correctly.

To upscale to a specific resolution like 1080p, you should use command-line arguments if they are supported. Unfortunately, I don't have the exact command-line syntax for upscayl-ncnn, but you would generally need to specify the desired width (1920 for 1080p) using a parameter like customWidth if available.

If command-line arguments are not working, you might need to check if there are any specific flags or options that need to be enabled for custom resolutions to work. Additionally, ensure that any scripts or batch files you are using to automate the process are correctly passing these parameters.

If none of these solutions work, it might be necessary to look into the codebase or documentation for more detailed instructions on setting custom resolutions in upscayl-ncnn.

Man i don't know what you are talking about, there aint no settings file or config file or smth similar to that, that folder is literally empty with 2 dll files and upscayl bin file.

Check the help options for upscayl-bin with ./upscayl-bin -h.
It should provide a custom width option as well as -s for scale.
