Q & A

  • What new feature was announced at 6 AM that everyone has been eagerly waiting for?

    -The new feature announced is AI character consistency, which allows for the stable generation of the same character.

  • How does the Mijurney character reference (CREF) feature work?

    -The Mijurney character reference (CREF) feature works by allowing users to reference a character's features using a URL of an image after adding a specific parameter (杠杠CREF) in the input text.

  • What is the purpose of the 杠杠CW parameter?

    -The 杠杠CW parameter adjusts the weight of the reference URL, determining how much detail from the reference image is incorporated into the generated image. The value ranges from 100 to 0, with higher values leading to more detailed references.

  • What is the recommended model version to use with the CREF feature?

    -The recommended model version to use with the CREF feature is MIGI6, as it currently only supports this version and not MIGI5.2 or earlier versions.

  • What are the benefits of using the CREF feature with Niji journey or Mi journey models?

    -Using the CREF feature with Niji journey or Mi journey models allows for the generation of characters with more consistent facial features and improved overall character recognition from reference images.

  • How does the precision of the CREF feature currently limit the details it can replicate?

    -The precision of the CREF feature is currently limited and cannot fully replicate intricate details such as dimples, freckles, or logos on t-shirts.

  • What happens when the 杠杠CW parameter is set to 0?

    -When the 杠杠CW parameter is set to 0, the generated image will primarily focus on replicating the facial features and will not significantly alter other aspects like clothing or hair.

  • How does the use of the ITA tag affect the generation process?

    -The ITA tag is used to specify the subject in the generation process, ensuring that the AI recognizes and incorporates the specified elements into the generated image.

  • What was the tribute made at the end of the script?

    -The tribute was made to the creator of Dragon Ball, Akira Toriyama, expressing respect and怀念 for the creator of a cherished childhood memory.

  • How did the demonstration of the CREF feature utilize the character Uchiha Itachi?

    -The demonstration used Uchiha Itachi as a reference character, showing how the CREF feature could change his clothing while maintaining his facial features and other distinctive attributes.

  • What was the unexpected result when the ITA tag was omitted and only the CREF feature was used?

    -When the ITA tag was omitted and only the CREF feature was used, the AI generated an image of a woman, possibly due to the influence of the 'pink' element in the input, showing that the AI can still generate consistent facial features without a specific character name.

🚀 Introduction to AI Character Consistency Feature

The paragraph introduces a new feature for AI character consistency, which allows for the stable generation of the same character. It discusses the excitement around this release, particularly for the AI known as me Joni, which has been criticized for lack of control in the past. The video aims to explain the Mijurney character reference (CREF) feature and its usage, comparing it to the previously released style reference feature. The CREF function involves adding a URL after a specific parameter, which is demonstrated practically in the video. It also mentions the new parameter 'CW' for adjusting the weight of the reference URL, with a range from 100 to 0, affecting the level of detail in the character's features. The feature is particularly effective when using images generated by the Mijurney model itself. The limitations of the feature, such as the inability to perfectly replicate details like dimples or logos, are acknowledged, but the potential for future improvements is highlighted. The CREF function is noted to support both Niji journey and me journey models but is only compatible with the MIGI6 model.

🎨 Demonstrating the CREF and CW Parameters

This paragraph continues the discussion on the CREF feature by providing a practical demonstration of its use. It showcases the process of generating images using the CREF and CW parameters, starting with selecting a character, in this case, Uchha Itoch from the anime. The video demonstrates how different CW values (0, 50, and 100) affect the generation, with varying levels of detail in the character's clothing and facial features. The paragraph also explores the effects of using CREF without specifying the character's name, showing how the AI can still generate a consistent facial appearance based on the reference image. The results of these tests are presented, highlighting the versatility and precision of the CREF feature in creating characters with specific attributes and clothing. The paragraph concludes with a tribute to the creator of Dragon Ball, Akira Toriyama, and a reminder to use the MIGI6 model for the best results.

Keywords

💡AI角色一致性

AI角色一致性 refers to the ability of an artificial intelligence system to generate images or descriptions of a character with consistent features and attributes over time. In the context of the video, this feature is significant because it allows for the stable generation of the same character, addressing previous issues with controllability. The video demonstrates how this feature can be used to maintain the character's identity even when changing certain elements like clothing or hairstyle.

💡Mijurney character reference (CREF)

Mijurney character reference, or CREF, is a newly introduced function that allows users to reference specific character traits when generating AI images. This feature is similar to the previously introduced style reference feature but focuses on character attributes. Users can input a URL of an image to use as a reference, and the AI will attempt to replicate the character's features in the generated image.

💡杠杠CW (CW parameter)

The 杠杠CW parameter, or CW for short, is a feature that adjusts the weight or influence of the reference URL in the AI's image generation process. The value of CW ranges from 100 to 0, with 100 being the default and representing the highest level of detail from the reference. Lower values reduce the influence of the reference image, allowing for more creative freedom while maintaining the character's facial features.

💡Miji

Miji refers to a platform or tool used for generating AI images, likely with a focus on character creation. In the video, Miji is mentioned in the context of the CREF feature, suggesting that it is the system where users can input commands and URLs to generate character images with the new consistency feature.

💡Niji journey

Niji journey is mentioned as a model within the Miji platform that specializes in generating anime-style characters. The video suggests that using the CREF feature with Niji journey yields particularly good results, indicating that this model is well-suited for creating consistent and detailed anime characters.

💡Swift function

💡权重 (Weight)

权重, or weight in English, refers to the influence or importance given to a particular parameter or factor in a process. In the context of the video, the CW parameter's weight determines how much detail from the reference image is replicated in the generated image. Adjusting the weight can help balance between maintaining character consistency and allowing for creative variations.

💡写实人物 (Realistic characters)

写实人物 refers to characters that are designed or generated to look as lifelike as possible. In the context of the video, the challenge of converting realistic characters into anime or other stylized forms is addressed by the new CREF feature, which can improve the facial consistency and overall quality of the transformation.

💡宇智波鼬 (Uchiha Itachi)

宇智波鼬, or Uchiha Itachi, is a character from the popular anime series 'Naruto'. In the video, Itachi is used as an example to demonstrate the effectiveness of the CREF feature in generating a consistent and recognizable character image, even when altering elements like clothing color.

💡鸟山明 (Akira Toriyama)
