Lecture on Set Extensions Using AI Workflows

Introduction

• Two workflows for creating set extensions:
  1. Allows selection of image areas to add elements, similar to Photoshop's generator field but enhanced.
  2. Integrates a 3D model with consideration for light direction, colors, and style.
• Excitement about the potential of these workflows to create amazing projects.

Workflow 1: 2D Set Extension

Steps:

1. Frame Preparation

   • Save the frame for set extension from your footage.
   • Option to track footage using tools like After Effects, Da Vinci Resolve, or Blender.

2. Software and Tools Setup

   • Install ComfyUI and necessary models from GitHub.
   • Configure ComfyUI environment and download models such as Wild Card Turbo and ControlNet.

3. Workflow Execution

   • Import the frame into ComfyUI.
   • Use the mask editor to define areas for set extension.
   • Add a creative prompt (e.g., spaceship ruins).

4. Image Generation and Adjustment

   • Adjust settings for image quality and realism (e.g., sun direction, shadows).

Explanation of Workflow Mechanics

• Image Scaling: Downscale for better composition, then upscale after generation.
• Prompt Management: Define positive and negative prompts.
• Masking: Uses blurred masks and line art to blend new and original images.
• Image Generation: K sampler and adjustments for denoising.

Workflow 2: 3D Matte Painting

Steps:

1. 3D Camera Tracking

   • Use Blender for 3D camera tracking.
   • Use selected tracking markers to set up the scene.

2. Modeling and Rendering

   • Simple box modeling for structures.
   • Render depth and line art passes for AI integration.

3. ComfyUI Integration

   • Import render passes and prompts into ComfyUI.
   • Use models for line art and depth to generate images.

4. Image Projection and Compositing

   • Use Blender to project generated images onto models.
   • Render and integrate into original footage.

Advanced Techniques and Adjustments

• Texture Variation: Generate different textures by changing prompts.
• Line Art Modification: Enhance details by editing line art in image editors.
• Combining Workflows: Use both workflows for comprehensive set extensions, adding 2D and 3D elements.

Conclusion

• Encouragement to explore and experiment with these workflows.
• Invitation to support on Patreon for more resources and community engagement.
• Call to share creations and feedback.
