Latent Video Diffusion Models【潜空间视频扩散模型】Video-LDMs 主要是在一个降低计算复杂度的潜在空间中训练了一个生成模型。大多数相关的工作都使用了一个预先训练过的文本到图像的模型,并将各种形式的时间混合层插入到预先训练过的体系结构中。Ge等人提出的方法额外依赖于时间相关噪声来增加时间一致性和简化学习任务。
Stable Video Diffusion探索了一个新的视频生成模型的训练范式,这套训练范式也为后续的工作提供了基础。SVD的训练分为三个阶段。第一阶段是文生图任务的预训练(Text To Video Pretraining),让模型初步具备视觉表征能力;第二阶段是视频任务的预训练(Video Pretraining),将图像模型迁移到视频模型当中;第三阶段是高质量...

Instead of training a new model from scratch,we canre-use an existing one as the starting point. We can take a model like Stable Diffusion v1.5 and train it on a much smaller dataset (the images of us), creating a model that is simultaneously good at the broad task of generating reali...
