Stable Video Diffusion

Stable Video Diffusion was proposed in Stable Video Diffusion: Scaling Latent Video Diffusion Models to Large Datasets by Andreas Blattmann, Tim Dockhorn, Sumith Kulal, Daniel Mendelevitch, Maciej Kilian, Dominik Lorenz, Yam Levi, Zion English, Vikram Voleti, Adam Letts, Varun Jampani, Robin Rombach.

The abstract from the paper is:

We present Stable Video Diffusion - a latent video diffusion model for high-resolution, state-of-the-art text-to-video and image-to-video generation. Recently, latent diffusion models trained for 2D image synthesis have been turned into generative video models by inserting temporal layers and finetuning them on small, high-quality video datasets. However, training methods in the literature vary widely, and the field has yet to agree on a unified strategy for curating video data. In this paper, we identify and evaluate three different stages for successful training of video LDMs: text-to-image pretraining, video pretraining, and high-quality video finetuning. Furthermore, we demonstrate the necessity of a well-curated pretraining dataset for generating high-quality videos and present a systematic curation process to train a strong base model, including captioning and filtering strategies. We then explore the impact of finetuning our base model on high-quality data and train a text-to-video model that is competitive with closed-source video generation. We also show that our base model provides a powerful motion representation for downstream tasks such as image-to-video generation and adaptability to camera motion-specific LoRA modules. Finally, we demonstrate that our model provides a strong multi-view 3D-prior and can serve as a base to finetune a multi-view diffusion model that jointly generates multiple views of objects in a feedforward fashion, outperforming image-based methods at a fraction of their compute budget. We release code and model weights at this https URL.

Tips

Video generation is memory-intensive and one way to reduce your memory usage is to set `enable_forward_chunking` on the pipeline’s UNet so you don’t run the entire feedforward layer at once. Breaking it up into chunks in a loop is more efficient.

Check out the Text or image-to-video guide for more details about how certain parameters can affect video generation and how to optimize inference by reducing memory usage.

( vae: AutoencoderKLTemporalDecoder image_encoder: CLIPVisionModelWithProjection unet: UNetSpatioTemporalConditionModel scheduler: EulerDiscreteScheduler feature_extractor: CLIPImageProcessor )

Parameters

- vae (`AutoencoderKLTemporalDecoder`) — Variational Auto-Encoder (VAE) model to encode and decode images to and from latent representations.
- image_encoder (CLIPVisionModelWithProjection) — Frozen CLIP image-encoder (laion/CLIP-ViT-H-14-laion2B-s32B-b79K).
- unet (`UNetSpatioTemporalConditionModel`) — A `UNetSpatioTemporalConditionModel` to denoise the encoded image latents.
- scheduler (EulerDiscreteScheduler) — A scheduler to be used in combination with `unet` to denoise the encoded image latents.
- feature_extractor (CLIPImageProcessor) — A `CLIPImageProcessor` to extract features from generated images.

Pipeline to generate video from an input image using Stable Video Diffusion.

This model inherits from DiffusionPipeline. Check the superclass documentation for the generic methods implemented for all pipelines (downloading, saving, running on a particular device, etc.).
