Given a video-text pair, our method, Tune-A-Video, fine-tunes a pre-trained text-to-image diffusion model for text-to-video generation.

• [02/08/2023] Colab demo released!
• [02/03/2023] Checkout our latest results tuned on Modern Disney and Redshift. Pre-trained Tune-A-Video models are available on Hugging Face Library.
• [01/28/2023] New Feature: tune a video on personalized DreamBooth models.
• [01/28/2023] Code released!

pip install -r requirements.txt

Installing xformers is highly recommended for more efficiency and speed on GPUs. To enable xformers, set enable_xformers_memory_efficient_attention=True (default).

[Stable Diffusion] Stable Diffusion is a latent text-to-image diffusion model capable of generating photo-realistic images given any text input. The pre-trained Stable Diffusion models can be downloaded from Hugging Face (e.g., Stable Diffusion v1-4, v2-1). You can also use fine-tuned Stable Diffusion models trained on different styles (e.g, Modern Disney, Redshift, etc.).

[DreamBooth] DreamBooth is a method to personalize text-to-image models like Stable Diffusion given just a few images (3~5 images) of a subject. Tuning a video on DreamBooth models allows personalized text-to-video generation of a specific subject. There are some public DreamBooth models available on Hugging Face (e.g., mr-potato-head). You can also train your own DreamBooth model following this training example.

To fine-tune the text-to-image diffusion models for text-to-video generation, run this command:

accelerate launch train_tuneavideo.py --config="configs/man-surfing.yaml"

Note: Tuning a video usually takes 300~500 steps, about 5~10 minutes using one A100 GPU and 10~20 minutes using one V100 GPU.

Once the training is done, run inference:

from tuneavideo.pipelines.pipeline_tuneavideo import TuneAVideoPipeline
from tuneavideo.models.unet import UNet3DConditionModel
from tuneavideo.util import save_videos_grid
import torch

pretrained_model_path = "./checkpoints/stable-diffusion-v1-4"
unet_model_path = "./outputs/man-surfing/2023-XX-XXTXX-XX-XX"
unet = UNet3DConditionModel.from_pretrained(unet_model_path, subfolder='unet', torch_dtype=torch.float16).to('cuda')
pipe = TuneAVideoPipeline.from_pretrained(pretrained_model_path, unet=unet, torch_dtype=torch.float16).to("cuda")
pipe.enable_xformers_memory_efficient_attention()

prompt = "a panda is surfing"
video = pipe(prompt, video_length=8, height=512, width=512, num_inference_steps=50, guidance_scale=7.5).videos

save_videos_grid(video, f"./{prompt}.gif")

[Training] a man is surfing.	a panda is surfing.	Iron Man is surfing in the desert.	a raccoon is surfing, cartoon style.

[DreamBooth] sks mr potato head.	sks mr potato head, wearing a pink hat, is surfing.	sks mr potato head, wearing sunglasses, is surfing.	sks mr potato head is surfing in the forest.

[Training] a bear is playing guitar.	a handsome prince is playing guitar, modern disney style.	a magical princess is playing guitar on the beach, modern disney style.	a rabbit is playing guitar, modern disney style.

[Training] a man is skiing.	spider man is skiing.	bat man is skiing.	hulk is skiing.
