TLDRIn this tutorial, Xiaoyuer introduces beginners to using Midjourney for AI-powered image generation. Starting with installing Discord, the tutorial guides through uploading an image, enlarging it, and copying its link. It explains how to use commands like '/image' in Discord to generate images with specific keywords and aspect ratios, ensuring characters remain consistent by adjusting 'IW' weights. The video also covers how to refresh and regenerate images until satisfaction, and how to enlarge and save the final results. Xiaoyuer shares tips for troubleshooting common issues, like ensuring the image link ends with 'PNG', and invites viewers to ask questions and share their experiences.

Takeaways

  • 📥 Install Discord to use Midjourney, as it operates as an AI within the platform.
  • 🖼️ Upload a picture to Midjourney by clicking the plus sign and then the upload option.
  • ⏏️ After uploading, click enter to ensure the message is visible before sending.
  • 🔍 Enlarge the image for better detail, then copy its link for further use.
  • 🔗 Paste the copied link into Discord with specific formatting to generate a similar image.
  • ✂️ Remove unnecessary parts of the link and add keywords for the desired outcome.
  • 📈 Use the 'AR' parameter to set the aspect ratio of the generated image.
  • 👧 Add 'IW' with a value to control the consistency of characters in the generated images.
  • 🔄 If unsatisfied with the generated images, refresh to regenerate a new set.
  • 🖼️ Satisfied images can be enlarged and saved directly from the platform.
  • ❓ For issues with copied links not working, ensure they end with a valid file extension like 'PNG'.

Q & A

  • What is the purpose of the video tutorial by Xiaoyuer?

    -The purpose of the video tutorial is to teach novice users how to use Midjourney to draw with pictures, making the drawing process simple and accessible.

  • Which platform does Midjourney operate on and why is it necessary to install Discord?

    -Midjourney operates on the Discord platform because it is a bot within Discord, an artificial intelligence tool that facilitates the drawing process.

  • How do you upload a picture to Midjourney for generating a similar image?

    -You upload a picture by clicking on the plus sign, then double-clicking to upload the image. After uploading, you click the enter key to send it.

  • What is the process of enlarging the uploaded picture in Midjourney?

    -To enlarge the picture, you click the left button to select it, right-click to copy the link, and then paste it into the appropriate field in Discord.

  • Why is it important to be careful with the format when sending the image link in Discord?

    -It's important because sending the image link directly without the correct format will result in an error, and the image will not be processed by Midjourney correctly.

  • What should be done with the row of numbers in the link before sending it to Midjourney?

    -The row of numbers should be deleted, and you should go to the end of the 'PNG' in the link, delete the part after it, and then add keywords and parameters as needed.

  • How can you ensure that the characters in the generated images remain consistent with the original?

    -To ensure character consistency, you can add the 'IW' parameter with a weight value of 0 to 2, with 2 being the highest for maximum similarity.

  • What does the 'AR' parameter represent and how is it used in Midjourney?

    -The 'AR' parameter stands for Aspect Ratio. It is used to set the desired ratio of the generated image, such as 16:9, 3:4, or 1:1.

  • How can you adjust the generated images if you are not satisfied with the result?

    -If you are not satisfied with the generated images, you can click to refresh and regenerate a new set of images.

  • What does the 'UE' option do in Midjourney and when should it be used?

    -The 'UE' option is used to enlarge the generated images. It should be used when you are satisfied with the images and want to view or save them in a larger size.

  • Why might the characters in the generated images change if not specified with 'IW'?

    -The characters might change because Midjourney generates images based on the input and parameters provided. Without specifying 'IW' to maintain consistency, the AI may interpret the input differently and create variations.

🖼️ Adjusting Picture Parameters and Consistency

In this part, Xiaoyuer delves into the specifics of maintaining character consistency in generated images by adjusting the weight (IW) parameter. She explains how changing the weight affects the similarity of characters to the original image and provides examples to illustrate this point. Additionally, Xiaoyuer discusses the aspect ratio (AR) parameter and how to properly format and apply it. The section concludes with a reminder on how to copy and use image links correctly to ensure the desired outcome. Xiaoyuer encourages viewers to like and share the video if they found it helpful.

Keywords

💡Midjourney

Midjourney refers to a specific AI tool that is used for generating images based on provided pictures or descriptions. In the context of the video, it is the primary subject being discussed, and it is used to demonstrate how to create art with AI assistance. The script mentions installing Discord to access Midjourney, indicating that it operates within that platform.

💡Discord

Discord is a communication platform that allows users to chat and share information in various channels. In the video script, it is mentioned as the necessary software to use Midjourney, suggesting that Midjourney operates as a bot or service within Discord, where users can interact with it to generate images.

💡AI绘图

AI绘图, or 'AI drawing' in English, refers to the process of using artificial intelligence to create artwork. The video is centered around teaching beginners how to use AI for drawing, specifically with the Midjourney tool, to generate images that are similar to uploaded pictures.

💡上传图片

Uploading pictures is the action of transferring images from a local device to a server or platform, which in this case is necessary for the Midjourney AI to generate similar images. The script describes the process of uploading a picture to Discord as the first step in using Midjourney.

💡相似图片

Similar images are pictures that have a resemblance to each other, often in terms of subject matter, style, or composition. The video explains how to use Midjourney to create images that are similar to the uploaded reference pictures, which is a key feature of the AI tool.

💡垫图

The term '垫图' is not explicitly defined in the script, but it could be inferred to mean a 'base image' or 'reference image' in English. This is the image that the AI uses as a foundation to create a new, similar image.

💡关键词

Keywords in the context of AI image generation are specific terms or descriptors that users provide to guide the AI in creating an image. The script mentions adding keywords after the image link to influence the style or elements of the generated image.

💡比例

Ratio, or '比例' in Chinese, refers to the aspect ratio of an image, which is the proportion of its width to its height. The script explains how to specify the aspect ratio (e.g., 16:9) when generating an image with Midjourney.

💡权重

Weight, or '权重' in Chinese, is a parameter that can be adjusted in AI image generation to control the degree of similarity between the generated image and the reference image. The script describes how setting a weight of 2 can make characters in the generated image more consistent with the original.

💡连续人物

Continuous characters refer to a series of images where the characters or subjects remain consistent across the series. The video mentions using Midjourney to generate a sequence of images for a comic or similar project where character consistency is important.

💡刷新

Refreshing, in the context of the video, means regenerating a new set of images with the AI tool if the user is not satisfied with the initial results. The script suggests that users can simply click to refresh and receive a new set of generated images.
