✨ Highlights

🔥 Masked Video Modeling for Video Pre-Training

VideoMAE performs the task of masked video modeling for video pre-training. We propose the extremely high masking ratio (90%-95%) and tube masking strategy to create a challenging task for self-supervised video pre-training.

⚡️ A Simple, Efficient and Strong Baseline in SSVP

VideoMAE uses the simple masked autoencoder and plain ViT backbone to perform video self-supervised learning. Due to the extremely high masking ratio, the pre-training time of VideoMAE is much shorter than contrastive learning methods (3.2x speedup). VideoMAE can serve as a simple but strong baseline for future research in self-supervised video pre-training.

😮 High performance, but NO extra data required

VideoMAE works well for video datasets of different scales and can achieve 87.4% on Kinects-400, 75.4% on Something-Something V2, 91.3% on UCF101, and 62.6% on HMDB51. To our best knowledge, VideoMAE is the first to achieve the state-of-the-art performance on these four popular benchmarks with the vanilla ViT backbones while doesn't need any extra data or pre-trained models.
