Q & A

  • What is the main topic of this tutorial?

    -The main topic of this tutorial is the application of the Seed parameter in generating images using the MidJourney (MJ) platform.

  • How can one find the Seed parameter of an image?

    -To find the Seed parameter of an image, one can refer to the previous tutorial mentioned in the script, specifically the 4th episode, where it was briefly explained.

  • What is the significance of the Seed parameter in image generation?

    -The Seed parameter is significant because it controls the randomness in image generation. A specific Seed value will produce a consistent output when used with the same description and aspect ratio.

  • What happens when the Seed value is not specified during image generation?

    -When the Seed value is not specified, the platform assigns a random Seed value, leading to different outcomes each time the generation process is run with the same description.

  • How does the aspect ratio parameter (ar16:9) affect image generation?

    -The aspect ratio parameter (ar16:9) controls the dimensions of the generated image, ensuring that the image has a width-to-height ratio of 16:9.

  • What is the range of possible Seed values?

    -The range of possible Seed values is from 0 to 4.2 billion, allowing for a vast number of unique image variations.

  • How can you ensure that two images generated with the same Seed value are identical?

    -To ensure that two images are identical, you must use the exact same Seed value, description, and aspect ratio parameters when generating the images. However, even with these conditions met, slight variations may occur depending on the model used (e.g., V4 vs V3).

  • What is the purpose of using the original image's link in the prompt?

    -Using the original image's link in the prompt helps the platform to better understand and control the visual elements of the generated image, aiming for a more consistent and desired output.

  • How does the tutorial demonstrate the control of image generation with Seed values?

    -The tutorial demonstrates the control of image generation by generating multiple images with different Seed values and then using the same Seed value for subsequent generations to produce consistent results.

  • What is the importance of understanding Seed values in creative work?

    -Understanding Seed values is important in creative work as it allows artists and designers to have more control over the visual outcomes, enabling them to produce a series of images with consistent themes or styles.

  • What is the next step for learners after this tutorial?

    -After this tutorial, learners are encouraged to practice using the Seed parameter and explore more advanced features of the MidJourney platform in future courses.



📚 Introduction to Seed Parameters in MidJourney

This paragraph introduces viewers to the concept of Seed parameters in MidJourney, a tool for image generation. The speaker references previous content, encouraging viewers to watch episode 4 for a basic understanding of Seed parameters. The main focus is on how to apply Seed parameters to control the randomness in image generation. The speaker guides the audience through the process of generating an image of a girl with a red hat, using a specific Seed value to demonstrate how it affects the output. The importance of Seed values in achieving consistency in image generation is emphasized, and viewers are invited to engage with the content by asking questions and providing feedback.


🎨 Fine-Tuning Image Generation with Seed Values

In this paragraph, the speaker delves deeper into the practical application of Seed values for fine-tuning image generation in MidJourney. The audience is shown how to use a specific Seed value to recreate a similar image, and how including the image link in the prompt can help maintain consistency. The speaker also discusses the differences between using V4 and earlier models of MidJourney, noting that V4 provides more consistent results with the same Seed value and description. The paragraph concludes with a demonstration of how to select an image for further creative work, highlighting the importance of understanding Seed values for controlled image generation and inviting viewers to explore this further on their own.




MJ refers to the platform or service being discussed in the video, which is likely an AI-based image generation tool. It is the central tool around which the tutorial is structured, and it is used to generate images based on user-provided descriptions and parameters.

💡Seed Parameters

Seed parameters, in the context of this video, are numerical values used in the image generation process to control the randomness and ensure consistency in the output. By specifying a seed value, users can recreate similar images with the same characteristics.

💡Image Generation

Image generation refers to the process of creating visual content using AI algorithms, as demonstrated in the video. This process involves inputting descriptions and parameters to produce images that match the given criteria.


A tutorial, as used in the context of this video, is an instructional guide or lesson designed to teach viewers how to use a specific tool or technology. The video serves as a tutorial for using the MJ platform to generate images.
