  • How does the user know if they need to retry an image generation in midjourney?

    -If there is a delivery failure, midjourney will display an error message, and the user can click a retry option to attempt the image generation again.

  • What are the different pricing plans mentioned for midjourney?

    -The pricing plans mentioned include a paid plan and a standard plan, with monthly costs ranging from 30 'knives' (a term used in the script, possibly referring to a currency), which is more than 200 RMB.

  • How can a novice afford to use midjourney for image creation?

    -Novice users can opt for a shared rental plan, which is a more cost-effective way to access midjourney's services, with prices starting at a standard 6-person monthly payment of 59.

  • What is the significance of the AR parameter in the midjourney command?

    -The AR parameter is used to set the aspect ratio of the generated image, which can be important for ensuring the image fits within certain dimensions or looks as intended.

  • How does the user know which image they have generated is the one they want to use?

    -After generating images, the user can review them and select the one they are most satisfied with, for example, by clicking on an image they find excellent.

  • What is the advice given for users who are confused by the midjourney process?

    -Users who are confused are advised to go back to Xiaoyuer's channel and watch some basic tutorials that cover the use of basic commands, aspect ratios, and other foundational knowledge.

🛒 Developing a Continuous Character with AI

The script explains how to develop a continuous character using AI by changing prompt words and using image links as references. It details the process of creating a shopping scene with a cat pushing a shopping cart in a supermarket. The importance of using the correct parameters and the IW (image weight) parameter for generating images with higher similarity to the original is highlighted. The video also provides tips on adjusting the IW weight for better results and suggests viewing basic tutorials for a better understanding of the process.

Keywords

💡midjourney

Midjourney refers to a specific tool or process used for generating images from existing images or descriptions. In the context of the video, it is a platform or software that allows users to create new images by providing a reference image and a descriptive prompt. It is central to the video's theme as it is the primary method demonstrated for image generation.

💡V6 version

The V6 version is a specific iteration or version of the midjourney tool being used. It implies that there have been previous versions and that this one comes with its own set of features and improvements. The script mentions using the V6 version to achieve certain effects, indicating its importance in the process.

💡descriptor

A descriptor in this context is a text input that describes the characteristics or appearance of the image the user wishes to generate. It is a key component in the image generation process as it guides the AI in creating the desired output. For example, the script mentions 'A super cute, super fat cat wearing a dress, and carrying a fashionable bag is coming to us' as a descriptor.

💡IW weight

IW weight stands for Image Weight and is a parameter used in the midjourney tool to control the influence of the reference image on the generated image. A higher IW weight means the generated image will be more similar to the reference image. It is used to maintain the consistency of a character across different images, as shown when the presenter adds an IW weight of 1.5 or 2 to achieve a higher similarity.

💡prompt

A prompt is a form of input, usually a phrase or sentence, that is used to instruct the AI on what kind of image to generate. It is closely related to descriptors and is often used interchangeably. In the video, prompts are used to guide the creation of various images, such as 'The cat is sitting on the ground crying' or 'The cat walked into the supermarket with a bag'.

💡character consistency

Character consistency refers to the maintenance of a character's visual appearance across multiple images or scenes. This is important in storytelling or when creating a series of images featuring the same character. The video discusses using midjourney and IW weight to ensure that the generated images of the cat maintain a consistent look.

💡Google Translate

Google Translate is mentioned in the script as a tool that can be used to translate descriptors into different languages. This can be helpful for users who want to generate images with descriptors in a language they are not familiar with, thus broadening the accessibility of the midjourney tool.

💡GPT

GPT, or Generative Pre-trained Transformer, is referenced as a tool that can assist users in creating descriptors for their images. It is an AI language model that can generate human-like text based on given prompts, which can be useful for users who need help formulating their image descriptors.

💡image link

An image link is a URL that points to the location of an image on the internet. In the context of the video, image links are used as references for the midjourney tool to generate new images. The presenter discusses copying and pasting image links into the tool to create images that are similar to the ones found at those links.

💡shared rental

A shared rental in the context of the video refers to a subscription model where multiple users share access to the midjourney tool, splitting the cost. This is presented as a more cost-effective option for users who are new to the tool or do not require exclusive access.

💡AI services

AI services are artificial intelligence tools or platforms that provide various functionalities, such as image generation, language translation, or text generation. In the video, AI services like midjourney and GPT are discussed as tools that facilitate the creation of images based on textual descriptions and reference images.
