Video diffusion models suffer compounding error due to representational collapse

Researchers have identified a key mechanism behind compounding error in video diffusion models, which degrades frame quality over long generation sequences. They discovered that this error accumulation is closely linked to a dimensional collapse in the model's internal representations, where the effective rank of these representations sharply decreases. Contrary to typical scaling paradigms, simply increasing training data did not improve the models' resistance to this error drift. To combat this, the team developed a novel video representation regularization technique that stabilizes latent representations and reduces iterative error accumulation, leading to significant improvements in video quality metrics on the VBench benchmark.
