😮 Highlights

MagicTime shows excellent performance in metamorphic video generation.

Metamorphic Videos vs. General Videos

Compared to general videos, metamorphic videos contain physical knowledge, long persistence, and strong variation, making them difficult to generate. We show compressed .gif on github, which loses some quality. The general videos are generated by the Animatediff and MagicTime.

We show more metamorphic videos generated by MagicTime with the help of Realistic, ToonYou and RcnzCartoon.

Integrate into DiT-based Architecture

The mission of this project is to help reproduce Sora and provide high-quality video-text data and data annotation pipelines, to support Open-Sora-Plan or other DiT-based T2V models. To this end, we take an initial step to integrate our MagicTime scheme into the DiT-based Framework. Specifically, our method supports the Open-Sora-Plan v1.0.0 for fine-tuning. We first scale up with additional metamorphic landscape time-lapse videos in the same annotation framework to get the ChronoMagic-Landscape dataset. Then, we fine-tune the Open-Sora-Plan v1.0.0 with the ChronoMagic-Landscape dataset to get the MagicTime-DiT model. The results are as follows (257×512×512 (10s)):

"Time-lapse of a coastal landscape [...]"	"Display the serene beauty of twilight [...]"	"Sunrise Splendor: Capture the breathtaking moment [...]"	"Nightfall Elegance: Embrace the tranquil beauty [...]"
"The sun descending below the horizon [...]"	"[...] daylight fades into the embrace of the night [...]"	"Time-lapse of the dynamic formations of clouds [...]"	"Capture the dynamic formations of clouds [...]"

🤗 Demo

Gradio Web UI

Highly recommend trying out our web demo by the following command, which incorporates all features currently supported by MagicTime. We also provide online demo in Huggingface Spaces.

python app.py

⚙️ Requirements and Installation

We recommend the requirements as follows.

git clone https://github.com/PKU-YuanGroup/MagicTime.git
cd MagicTime
conda env create -f environment.yml
conda activate magictime

🗝️ Training & Inference

The training code is coming soon! For inference, some example are shown below:

# For [Realistic](https://civitai.com/models/4201/realistic-vision-v20)
python inference_magictime.py --config sample_configs/RealisticVision.yaml
# For [ToonYou](https://civitai.com/models/30240/toonyou)
python inference_magictime.py --config sample_configs/ToonYou.yaml
# For [RcnzCartoon](https://civitai.com/models/66347/rcnz-cartoon-3d)
python inference_magictime.py --config sample_configs/RcnzCartoon.yaml

# or you can directly run the .sh
sh inference.sh

🐳 ChronoMagic Dataset

ChronoMagic with 2265 metamorphic time-lapse videos, each accompanied by a detailed caption. We released the subset of ChronoMagic used to train MagicTime. The dataset can be downloaded at Google Drive. Some samples can be found on our Project Page.
