Q & A

  • What is the main topic of the video?

    -The main topic of the video is introducing the Fooocus update, specifically focusing on the Image prompt feature and comparing it with Control Net's Canny and Depth.

  • How does Fooocus's Image prompt differ from stable diffusion's IP-Adapter?

    -Fooocus's Image prompt is characterized by not reducing the quality of the image, whereas stable diffusion's IP-Adapter tends to ignore text prompts and the image quality deteriorates when many images are used.

  • What is the purpose of the control weight in the multi-control net?

    -The control weight is used to determine the influence of the image in control units on the generated image. A higher weight means a stronger influence on the final output.

  • How can one adjust the influence of an Image Prompt in Fooocus?

    -One can adjust the influence of an Image Prompt by using the 'Weight' and 'Stop At' options available in the advanced settings of the Image Prompt feature.

  • What is the role of the 'Stop At' setting in the Image Prompt?

    -The 'Stop At' setting determines at what point in the image generation step the effect of the Image Prompt should be stopped.

  • How does Fooocus's Image Prompt handle the combination of text prompts with image prompts?

    -Fooocus allows the combination of text prompts with image prompts, and the influence of each can be adjusted using the 'Weight' setting to achieve the desired output.

  • What is the Pyramid Canny mode in Fooocus's Image Prompt?

    -Pyramid Canny is a mode that captures the contours well by performing Canny at multiple resolutions and blending the elements softly, which is useful for high-resolution images.

  • What is the significance of the 'CPDS' mode in Fooocus's Image Prompt?

    -CPDS stands for contrast, preserving decolorization structure. It removes color and makes the image black and white while maintaining the contrast and the sense of perspective perceived by human vision.

  • How does Fooocus's Image Prompt compare to DALL-E3 in terms of prompt understanding?

    -In the example provided, Fooocus accurately generates the number of people and gender as per the prompt, similar to DALL-E3, while SD1.5 and stable diffusion webui SDXL have some discrepancies.

  • What is the difference between Fooocus and stable diffusion webui when using SDXL?

    -The video suggests that Fooocus consistently outperforms stable diffusion webui when using the SDXL model, possibly due to hidden optimizations and additional features in Fooocus.

  • Why does the presenter prefer SDXL over SD1.5?

    -The presenter prefers SDXL due to its better language understanding of prompts, higher resolution capabilities, and the fine pixel quality compared to SD1.5.

  • How does the presenter suggest utilizing SDXL effectively?

    -The presenter suggests that since there are AI models that can create complex images with just words, it's important to find ways to effectively utilize SDXL, which is still close to that capability.
