In the video, Bob Deffy from Intel demonstrates generating high-quality, realistic images using the a1111 web UI interface for stable diffusion, powered by OpenVino script and Intel Arc GPU. He covers essential settings and processes, including selecting the appropriate device and utilizing specific prompts to refine image outputs. Emphasizing the use of models tailored for realistic rendering, Bob highlights alternatives like 'Realistic Vision' and 'rev animated' over the standard 'Stable Diffusion 1.5' to achieve superior results.
Further, Bob discusses the importance of effective image prompting and model selection from civitai.com for achieving the desired outcome. He explains downloading and setting up different models, focusing on refining images through techniques like inpainting, adjusting resolution, and using specific denoising strengths. He demonstrates how to fine-tune facial features and other details to enhance realism.
Finally, Bob compares various models' outputs and emphasizes their distinct visual styles, inviting viewers to join a Discord community for generative AI enthusiasts and PC fans. The video concludes with a call to action for viewers to like, subscribe, and engage with the community.

In this segment of the video, Bob Deffy from Intel demonstrates how to generate amazing images using the a1111 web UI interface for stable diffusion, powered by OpenVino script and an Intel Arc GPU. He clarifies that this video is not about installation instructions but usage. For installation guidance, viewers are advised to check his article at Art.intel.com, which includes a link to the GitHub repository for the necessary code.
Bob then walks through the initial setup steps in the a1111 interface. Users need to select the “accelerate with open Vino” script from the script area and choose the appropriate device (CPU or GPU). He highlights the importance of ensuring that the correct GPU is selected by cross-referencing with the Task Manager. For his demonstration, Bob uses the Intel Arc GPU and adjusts settings for a more realistic output, including choosing the DPM++ 2 M Caris option to match his model and inputting his frequently-used prompts.

In this part of the video, the presenter explains their process of testing image generation using a specific model to achieve realistic results. They discuss the importance of avoiding cartoonish or painted looks by inputting certain keywords. The presenter demonstrates generating images using a command window, highlighting the initial longer compilation time, which speeds up for subsequent images. They showcase the outputs of four images, detailing how different checkpoints and models tailored for realism produce superior results compared to standard ones. The ‘Realistic Vision’ model yields impressive images, unlike the more cartoonish results from models such as ‘Rev animated’ and the less consistent base ‘Stable Diffusion 1.5’. The presenter emphasizes the community’s contribution to creating custom models that enhance specific styles or outputs.

In this part of the video, the speaker explains the importance of effective prompting to obtain desired results from AI models, and they suggest using specific models found on civitai.com. They recommend looking for well-rated and popular checkpoints rather than the “Aura” tagged models. The speaker demonstrates the process of downloading and using a model, emphasizing placing it in the correct folder within Stable Diffusion. They select the “rev animated” model for its stylistic and photo-realistic qualities useful for fantasy art. After setting up the model, the speaker prepares to use the a1111 interface, highlighting the need to refresh the setup and use specific prompts for detailed control. They switch to the “cyber realistic” model, select a VAE for image refinement, and change the seed to match a desired image outcome based on previous generated images.
00:09:00
In this part of the video, the speaker explains how to fine-tune an image using prompts and other means by utilizing the seed selection and GPU power. The process begins with selecting a preferred seed and generating images, which initially takes longer due to a model change but speeds up subsequently. The speaker evaluates the generated images, picking a favorite, and notes that some facial details require adjustment. They demonstrate the use of inpainting, selecting and masking parts of the image (e.g., the face), and applying specific prompts to refine features like the eyes. The process involves using the image-to-image tab and adjusting settings to achieve a more detailed and realistic output.
00:12:00
In this segment of the video, the speaker discusses selecting the same scheduler and preparing to modify an image by painting a specific area. Key settings include mask mode in “painted,” mask content set to “original,” and working with the original information under the mask (e.g., eyes, nose, and mouth). The user sets the new image size to 512×512 for higher resolution and chooses a batch process, retaining the seed. They adjust the denoising strength, explaining that a lower value keeps the image closer to the original, while a higher value deviates more based on the prompt. After running the process, the speaker observes increased detail, especially around the eyes, and tweaks the denoising strength to add more variation and detail.
00:15:00
In this part of the video, the presenter showcases the results of running image generation processes at 9-plus iterations per second, noting that inpainting takes slightly longer. The images produced are compared to an original image, highlighting differences and similarities. Various models and their outputs are examined, including Realistic Vision, Rev Animated, Cyber Realistic, and stable diffusion 1.5, each providing distinct visual styles. The presenter emphasizes the importance of choosing appropriate models and invites viewers to join a Discord community dedicated to PC enthusiasts and generative AI. The segment concludes with the presenter signing off and encouraging viewers to like, subscribe, and join the community.
