The codebase was designed to help researchers and practitioners quickly reproduce FAIR’s results and leverage robust pre-trained backbones for downstream tasks. It also integrates Gradient Blending, an audio-visual modeling method that fuses modalities effectively (available in the Caffe2 implementation). Although VMZ is now archived and no longer actively maintained, it remains a valuable reference for understanding early large-scale video model training, transfer learning, and multimodal integration strategies that influenced modern architectures like SlowFast and X3D.

Features

  • Implements R(2+1)D and MCx models for efficient spatiotemporal video representation learning
  • Enables reproducibility of FAIR’s published video understanding research
  • Built with both Caffe2 and PyTorch backends for flexibility
  • Supports Gradient Blending for audio-visual fusion (Caffe2 only)
  • Provides pre-trained models on IG-65M, one of the largest weakly-supervised video datasets
  • Includes CSN (Channel-Separated Networks) for computationally efficient video recognition
