Proposes a two-stage training scheme that turns a pretrained Stable Diffusion into a pose-controllable text-to-video generator, learning pose control from image-pose pairs (LAION-Pose) and temporal coherence from pose-free videos (HD-VILA).

Problem

Pose-controllable, text-editable character video generation is hard because no large dataset of paired video-pose-caption data exists and video generative priors are limited.

Approach

Decouple pose control from temporal consistency: a zero-initialized residual pose encoder is trained on image-pose pairs with the T2I U-Net frozen, then only temporal self-attention and cross-frame self-attention are tuned on pose-free videos, with a noise-reuse scheme for longer videos.
