The session aims to clarify the use of parameters to control image attributes and the creative process, providing practical examples and advice for effective utilization in various scenarios.
Takeaways
- 📌 Midjourney parameters are crucial for guiding the image generation process based on prompts.
- 🔍 Parameters are categorized into instructions, keywords, and specific settings that adjust image attributes and constrain the bot's creative scope.
- 🎨 The most common parameter is the aspect ratio (--ar), which dictates the shape of the generated image, like 1:1 for a square.
- 🖼️ Image weight (--iw) adjusts the influence of a reference image on the final output, with a range of 0.5-2.
- 👁️ Quality (--q) controls the level of detail in the image, with lower values resulting in more abstract and blurry outputs.

Q & A
What is the primary function of parameters in Midjourney's image generation process?
-The primary function of parameters in Midjourney's image generation process is to adjust the attributes of the image and constrain the robot's drawing scope. They are essentially part of the prompt and play a crucial role in determining the final image output.
How are parameters categorized in relation to the prompt in Midjourney?
-In Midjourney, the prompt is divided into three parts: instructions, keywords, and parameters. Instructions and keywords are relatively straightforward, while parameters can be more abstract and may require more time to understand due to their variety and functions.
What is the format and purpose of the aspect ratio parameter in Midjourney?
-The aspect ratio parameter, formatted as '--ar', is used to specify the desired shape of the image. For example, '--ar 1:1' would create a square image. This parameter is essential for controlling the composition of the generated image.
How does the image weight parameter (--iw) influence the image generation in Midjourney?
-The image weight parameter (--iw) is used when a base image or '垫图' is provided. It adjusts the influence of the base image versus the keywords on the final image. A higher '--iw' value means the generated image will more closely resemble the base image.
What is the purpose of the quality parameter (--q) in Midjourney?
-The quality parameter (--q) controls the level of detail in the generated image. A lower value results in a more abstract and blurry image, while a higher value produces a more detailed and specific image.
What is the range of values for the stylelize parameter in Midjourney, and how does it affect the image?
-The stylelize parameter, formatted as '--s', has a range of values from 0 to 1000. It adjusts the degree of stylization of the image. Higher values intensify the chosen style, such as making a cat 'super cute' if 'cute' is the style being emphasized.
Why are style parameters less commonly used in Midjourney's V5 model?
-In Midjourney's V5 model, style parameters are less commonly used because they have been largely replaced by keywords. Keywords can now directly describe the style of the image, eliminating the need for separate style parameters.
What does the seed parameter in Midjourney represent?
-The seed parameter represents the image encoding or '身份证' used by the robot to generate images. It is a unique identifier for the visual output based on the prompt and is part of the robot's drawing logic.
How does the stop parameter affect the completion of an image in Midjourney?
-The stop parameter, with a range of 10-100, regulates the completeness of the image generation. A lower stop value, such as 50, would cause the robot to stop the image creation process at 50% completion.
What is the default number of images generated by Midjourney for a single prompt?
-By default, Midjourney generates 4 images for a single prompt, representing the robot's repeated attempts at creating the image based on the provided parameters and keywords.
How can users adjust the variation in images generated by Midjourney?
-Users can adjust the variation in images by modifying the chaos parameter. A higher chaos value (within the 0-100 range) will result in greater differences among the generated images.
Outlines
🎨 Introduction to Midjourney Parameters
This paragraph introduces the concept of Midjourney parameters, emphasizing their importance in the image generation process. It explains that parameters are part of the prompt and significantly influence the outcome of the generated images. The speaker breaks down the prompt into three parts: instructions, keywords, and parameters, noting that parameters can be abstract and challenging for beginners to understand. The purpose of the session is to clarify the use of parameters and their impact on image attributes and the bot's drawing scope.
📐 Understanding and Using Common Parameters
The speaker delves into the specifics of common parameters like aspect ratio (--ar), image weight (--iw), and quality (--q). Aspect ratio is used to determine the shape of the image, with examples provided for square, landscape, and portrait formats. Image weight affects how much the bot references a base image when creating new images. Quality parameter adjusts the level of detail and clarity in the final image, with different settings for abstract to highly detailed outputs. The speaker also mentions that these parameters can be set within the bot's settings for convenience.
🌟 Exploring Style and Other Special Parameters
This section covers the stylelize parameter, which adjusts the degree of a particular style in the image, using the example of a cat's cuteness. It also discusses the style parameter, which is now largely replaced by keywords. The speaker clarifies the difference between style and stylelize parameters and notes that certain style parameters like expressive and cute are still available in the Niki5 model. The paragraph also briefly touches on less frequently used parameters such as delete (--no), seed, stop, repeat, and chaos (chaos), providing examples and explanations for each.
🚀 Practical Application and Conclusion
The speaker concludes by demonstrating the practical application of the discussed parameters in a real-world scenario, combining keywords with aspect ratio, quality, and stylelize parameters to generate an image. The paragraph emphasizes the flexibility in using these parameters based on the creator's needs and encourages viewers to revisit the content for better understanding. The speaker also promises future content on advanced usage of Midjourney and encourages viewers to subscribe and turn on notifications for updates.

Highlights
Midjourney's drawing logic is based on robot-generated images according to provided prompts.
Parameters are an essential part of the prompt that significantly influence the drawing outcome.
The prompt is divided into three parts: instructions, keywords, and parameters.
Parameters adjust image attributes and constrain the robot's drawing scope.
The most commonly used parameter is the aspect ratio (--ar), which controls the shape of the image.
In V5 and Niki5 models, any aspect ratio can be set, and common ratios include 1:1, 5:4, 3:2, 7:4.
Image weight parameter (--iw) is used when a base image is provided to influence the robot's reference to it.
Quality parameter (--q) adjusts the level of detail in the image, with lower values resulting in more abstract and blurry images.
Stylelize parameter (--s) controls the degree of style expression in the image, such as how 'cute' a cat appears.
Style parameter (--style) is rarely used now as keywords have largely replaced it in V5 models.
Delete parameter (--no) removes unwanted elements from the image based on the prompt.
Seed parameter (--seed) represents the image encoding used by the robot for each drawing.
Stop parameter (--stop) regulates the completion percentage of the robot's drawing.
Repeat parameter (--repeat) sets the number of times the robot draws based on the prompt.
Chaos parameter (--chaos) adjusts the variation among the multiple images generated by the robot.
In practical creation, the most frequently used parameters are aspect ratio, image quality, style level, and base image weight.
Parameters like delete, seed, stop, repeat, and chaos are used sparingly and only in specific situations.
Understanding parameters takes time and practice, and it's recommended to review the material multiple times for clarity.
