Reposer = Consistent Stable Diffusion Generated Characters in ANY pose from 1 image!
TLDRThe video introduces a new workflow called 'reposer' that combines an IP adapter face model with an open pose control net, allowing users to create a consistent, posable character from a single face image. The presenter demonstrates how changing the background and pose affects the character while maintaining facial consistency. The workflow is easy to set up and use, with detailed instructions and model links provided on the Comfy UI website. Users can experiment with various images and poses to generate unique characters quickly and efficiently.

Q & A
What is the main topic of the video?
-The main topic of the video is the introduction of a new UI workflow called 'reposer', which combines an IP adapter face model with an open pose control net to create a consistent, posable character from a single face image.
How does the reposer workflow work?
-The reposer workflow works by using a single input image of a face to generate a character in various poses. The user can guide the generation process with prompt controls to maintain consistency in the character's appearance and style across different poses and backgrounds.
What kind of character is used as an example in the video?
-The example character used in the video is a 1970s style detective, with a focus on the face and elements of clothing such as a large, collared leather jacket.
How can the background color change affect the image?
-Changing the background color can alter the entire aesthetic of the image, including the character's appearance, while still maintaining the consistency of the face and overall character design.
What are the different types of models used in the reposer workflow?
-The reposer workflow uses various models including stable diffusion 1.5 checkpoint loader, open pose control net for stable diffusion 1.5, CLIP Vision IP adapter stable diffusion 1.5 image encoder, and an IP adapter face model for stable diffusion 1.5.
How can users organize their models for easier access?
-Users can organize their models into subdirectories and use color coding and labeling to easily identify and select the required models for different loaders.
What happens when using different models in the IP adapter?
-Using different models in the IP adapter can influence the style and realism of the generated images. For instance, a model tailored towards photo realism may introduce some realism into a cartoon character if used inappropriately.
How can users control the influence of the prompt in the image generation process?
-Users can adjust the prompt strength, which by default is set to 1, to control how much influence the face in the IP adapter has on the generated image.
What is the purpose of the 'batch' mode in the reposer workflow?
-The 'batch' mode allows the use of multiple images in the IP adapter, resulting in a blend of the faces from the images, creating a merged character design.
How can users experiment with the reposer workflow?
-Users can experiment by trying out various images, including partial faces, full bodies, half bodies, paintings, anime photos, and even images with no face at all. They can also play with different poses and prompts to see how the character adapts and changes.
Where can users find more information and links related to the reposer workflow?
-More information and links to models can be found on the 'a very comfy nerd' webpage, which is also mentioned in the video description for further exploration and guidance.
Outlines
🎨 Introducing the Reposer Workflow for Character Consistency
This paragraph introduces the viewer to the Reposer workflow, a UI designed to create a consistent, posable character using the IP adapter face model combined with an open pose control net. It emphasizes the ease of generating a character in any pose with prompt control for guidance. The speaker shares an example of their original character, a 1970s style detective, and demonstrates how changing the background color affects the image while maintaining the character's consistency. The paragraph also touches on the flexibility of using different types of images and encourages experimentation with the workflow.
🖌️ Model Selection and Organization for Image Generation
The second paragraph delves into the importance of selecting the right model for image generation, especially when aiming for a specific style like photo-realism or cartoon. It explains how the chosen model influences the output and suggests opting for a cartoon-oriented model for generating cartoon characters. The speaker also discusses organizing models into subdirectories for easier searching and provides tips on filtering results within Comfy UI. The paragraph outlines the requirements for the workflow, including the stable diffusion 1.5 checkpoint loader, open pose model, CLIP Vision IP adapter, and upscaling models, emphasizing the need to match the model to the desired output style.
🚀 Using the Reposer Workflow: A Step-by-Step Guide
This paragraph provides a step-by-step guide on how to use the Reposer workflow. It instructs users to drag an image onto the face box and a pose into the pose box, then click 'Q prompt' to generate the character. The speaker explains that optional prompts can help maintain consistency, such as giving the character a name or specifying clothing. The paragraph also discusses the option to change the face from realistic to a more cartoony style and how the character's appearance will adapt accordingly. Additionally, it covers the controls at the top of the UI, such as prompt strength and the option to use a single image or a batch, which can create a blend of two different faces.
