Video Generation with Predictive Latents
TLDR
Introduces PV-VAE, a video VAE with predictive reconstruction that improves generation quality and convergence speed.
Reasoning
Strengths: Simple yet effective predictive objective that enhances video dynamics understanding, with clear empirical gains (52% faster convergence, 34.42 FVD improvement). Weaknesses: Limited to UCF101 benchmark; no discussion of failure cases or broader real-world deployment.

Innovations
- Predictive reconstruction objective that unifies predictive learning with video reconstruction
- Randomly discarding future frames and encoding only partial past observations while training decoder to reconstruct observed and predict future frames
- PV-VAE model that improves latent space temporal coherence and motion priors
Methodology
The method introduces a predictive reconstruction objective for video VAEs. During training, future frames are randomly discarded, and only partial past observations are encoded. The decoder is trained to simultaneously reconstruct the observed frames and predict the future ones, encouraging the latent space to encode temporally predictive structures.
Key Results
PV-VAE achieves 52% faster convergence and a 34.42 FVD improvement over Wan2.2 VAE on UCF101. It also shows favorable scalability and consistent gains in downstream video understanding.
