Video VAEs typically adopt 3D convolution or causal convolution structures to compress consecutive frames into a single temporal token, thereby reducing the computational burden of temporal modeling.

UnverifiedVideo VQ-VAE, 3D convolution, and encoding uniformly sampled keyframes with ViT are the mainstream video tokenization methods.77% similarUnverifiedOffline inference can access the preceding and following frames of the entire video for bidirectional temporal aggregation, giving usually higher accuracy but unacceptable latency; the streaming mode can only use the current frame and a limited history state, giving controllable memory and latency but degraded performance.72% similarUnverifiedIn image-to-video generation, the conditioning image is typically encoded into a latent-space representation via a VAE and then concatenated with the noise sequence or injected into the generation process through cross-attention.72% similar
