Model description 🚀

This repository contains unet_lora.pt that can turn VideoCrafter2 into our <span style="font-family: 'Courier New', monospace; font-weight: bold">T2V-Turbo</span> (VC2). Our <span style="font-family: 'Courier New', monospace; font-weight: bold">T2V-Turbo</span> (VC2) can achieve both fast and high-quality T2V generation. On VBench, the 4-step generation from our <span style="font-family: 'Courier New', monospace; font-weight: bold">T2V-Turbo</span> (VC2) even outperform proprietary systems, including Gen-2 and Pika. Please refer to our GitHub repo for detailed instructions.

Usage 👓

This checkpoint is obtained by merging the UNet LoRA weight to the UNet of VideoCrafter2. Therefore, the checkpoint here is also under the apache-2.0 license.

You need to first clone our GitHub repo. Here are the codes to load the checkpoint.

from utils.common_utils import load_model_checkpoint
from utils.utils import instantiate_from_config


config = OmegaConf.load("configs/inference_t2v_512_v2.0.yaml")
model_config = config.pop("model", OmegaConf.create())
pretrained_t2v = instantiate_from_config(model_config)

unet_config = model_config["params"]["unet_config"]
unet_config["params"]["time_cond_proj_dim"] = 256
unet = instantiate_from_config(unet_config)
pretrained_t2v.model.diffusion_model = unet
pretrained_t2v = load_model_checkpoint(pretrained_t2v, "checkpoints/t2v_turbo_vc2.pt")
