TLDRThe video introduces a new feature, Character Reference (D-C ref), for maintaining character consistency across generations in Mid Journey. Users can input an image URL, which can be a selfie or any image found online, to influence the character's traits. The reference strength (CW) can be adjusted from 100 to zero, affecting how closely the generated character resembles the reference image. The feature works best with characters made from Journey images and can be combined with Style (SRE) to apply any desired style. Experiments with non-human subjects like animals and robots show varying results, and the video also explores the use of multiple character references and different styles, demonstrating the flexibility and potential of this tool for creative expression.

Q & A

  • What is the purpose of using a character reference in Mid Journey?

    -The purpose of using a character reference in Mid Journey is to maintain the consistency of characters across generations. It allows users to input an image URL and have the AI model focus specifically on the character traits, ensuring that the generated images retain the desired features.

  • How does the D-C ref command work in Mid Journey?

    -The D-C ref command works by typing 'D-C ref' followed by a space and then pasting the URL of the image you want to use as a reference. This can be an image generated inside Mid Journey or any other image URL. The command helps to focus the AI on the character traits of the image provided.

  • What is the role of the D-CW parameter in character reference?

    -The D-CW parameter is used to modify the reference strength of the character reference image. It can be adjusted from 100 to zero, with 100 making the generated image look very similar to the character in the reference, and zero making it look more like the facial features but with less resemblance to the original character's overall appearance.

  • Is the character reference feature designed for real people photos?

    -The character reference feature is primarily designed for use with characters made from Mid Journey images. It is not specifically designed for real people photos, but it can still be used with them, albeit with some limitations.

  • Can character reference be combined with style transfer in Mid Journey?

    -Yes, character reference can be combined with style transfer in Mid Journey. This allows users to apply any desired style to the character while maintaining the character traits from the reference image.

  • What happens when using character reference with more than two characters?

    -Using character reference with more than two characters can lead to confusion, as the AI may start merging the characters together. The performance tends to decrease when trying to include three or more characters in the same scene.

  • How does changing the CW value affect the generated image?

    -Changing the CW value affects the level of detail and similarity to the character reference. Lower values like 20 will bring the facial expression and style of hair but may start to change other aspects too much. Higher values like 100 will retain more specific traits like tattoos and small details, making the generated image very similar to the reference.

  • Can character reference be used with different styles?

    -Yes, character reference can be used with different styles. The script demonstrates using the same character in a photorealistic style, an illustrated style, and even a Disney-Pixar character style, showing that the consistency of the character can be maintained across various artistic interpretations.

  • How does character reference work with non-human subjects like animals or robots?

    -Character reference can be applied to non-human subjects as well. The script shows examples of using a European bird and a robot design as references. While there might be some discrepancies in small features, the overall character traits are preserved, demonstrating the versatility of the feature.

  • Can character reference be used for products?

    -Yes, character reference can be used for products. The script provides an example of using a perfume bottle as a reference, showing that the AI can pick up on certain aspects like roundness and apply them to the generated product image, although it may require some adjustment of values for the best result.

  • What was the outcome when the user tried to use their own selfie as a character reference in Mid Journey?

    -When the user tried to use their own selfie as a character reference with a CW value of 70, the generated image was not an exact replica but rather a version that looked similar to the user. The AI took the general traits but did not produce a photorealistic version, indicating that the feature may work better with fictional characters or images generated within Mid Journey.

Keywords

πŸ’‘Character Reference

Character Reference is a feature that allows users to maintain consistency in the appearance of their characters across different generations or iterations within an AI-based art generation platform. It is used by typing 'D-C ref' followed by a space and pasting the URL of an image, which can be a selfie, an image from the internet, or one generated within the platform. The reference image helps the AI focus on specific character traits, ensuring that the generated images retain the desired features.

πŸ’‘Reference Strength (CW)

Reference Strength, denoted as 'CW' in the script, is a parameter that users can adjust to control the influence of the character reference image on the generated artwork. The strength can be set from 100 to zero, with 100 meaning the generated image will closely resemble the reference, and zero allowing for more creative freedom while still retaining some facial features. This flexibility allows users to balance between consistency and variety in their character designs.

πŸ’‘M Journey

M Journey refers to the mid-journey phase of an AI art generation process, where users can refine and develop their characters further. It is a stage where character references and style adjustments become particularly important to achieve the desired aesthetic and consistency in character design.

πŸ’‘Style Transfer (SRE)

Style Transfer, or 'SRE' as mentioned in the script, is a technique that allows users to apply a specific artistic style to their character references. This can range from photorealistic to stylized looks like those from Disney Pixar. The style transfer is applied on top of the character traits, allowing for a unique blend of visual consistency and artistic expression.

πŸ’‘Non-Human Characters

Non-Human Characters refer to characters that are not human, such as animals or robots. The script discusses the use of character references for non-human entities, demonstrating the versatility of the AI in capturing and applying traits from various types of subjects, not just humans.

πŸ’‘Alien Creatures
