Transform Video Footage into 3D Models: A Complete Guide for Game Developers

Converting video footage into 3D models has become a game-changer for developers seeking efficient ways to create high-quality assets. Whether you’re a game developer racing against deadlines, a technical artist focusing on quality, or an indie developer working with limited resources, this guide will show you how to transform video footage into professional 3D models using cutting-edge techniques.

Methods

Photogrammetry

Photogrammetry converts video footage into a sequence of images to generate detailed 3D models. This technique excels at capturing fine details and textures, making it ideal for creating realistic game assets.

NeRF (Neural Radiance Fields)

NeRF technology uses AI to predict 3D scenes from 2D images taken at different angles. This cutting-edge approach creates highly photorealistic models viewable from any angle, perfect for interactive gaming environments.

Videogrammetry

A direct video-to-3D conversion method that, while potentially faster than traditional photogrammetry, may sacrifice some detail quality for convenience.

Step-by-Step Workflow

1. Capturing Video Footage

  • Use a high-resolution camera
  • Ensure consistent lighting
  • Move around the subject in complete loops
  • Capture from multiple heights
  • Maintain steady movement

2. Processing Your Footage

For Photogrammetry:

  1. Convert your video to image sequences using tools like ezgif or DaVinci Resolve
  2. Select 150-250 clear, well-exposed frames
  3. Use make 3d models from photos services to process your images
  4. Clean up and optimize the resulting model

For NeRF:

  1. Upload your video directly to a NeRF processor
  2. Allow AI to analyze the footage
  3. Export in your preferred format (GLTF, OBJ, or USDZ)
