This repository is the official implementation of MagicTime, a metamorphic video generation pipeline based on the given prompts. The main idea is to enhance the capacity of video generation models to accurately depict the real world through our proposed methods and dataset.

## 📣 News * ⏳⏳⏳ Training a stronger model with the support of [Open-Sora-Plan](https://github.com/PKU-YuanGroup/Open-Sora-Plan) (e.g 257 x 512 × 512). * ⏳⏳⏳ Release the training code of MagicTime. * **[2024.04.10]** 🔥 We release the inference code, huggingface space and model weight of MagicTime. * **[2024.04.09]** 🔥 We release the arXiv paper for MagicTime, and you can click [here](https://arxiv.org/abs/2404.05014) to see more details. * **[2024.04.08]** 🔥 We released the subset of ChronoMagic dataset used to train MagicTime. The dataset includes 2,265 metamorphic video-text pairs and can be downloaded at [Google Drive](https://drive.google.com/drive/folders/1WsomdkmSp3ql3ImcNsmzFuSQ9Qukuyr8?usp=sharing). * **[2024.04.08]** 🔥 **All codes & datasets** are coming soon! Stay tuned 👀! ## 😮 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](https://github.com/guoyww/AnimateDiff) and **MagicTime**.

### Gallery We showcase some metamorphic videos generated by **MagicTime**, [MakeLongVideo](https://github.com/xuduo35/MakeLongVideo), [ModelScopeT2V](https://github.com/modelscope), [VideoCrafter](https://github.com/AILab-CVC/VideoCrafter?tab=readme-ov-file), [ZeroScope](https://huggingface.co/cerspense/zeroscope_v2_576w), [LaVie](https://github.com/Vchitect/LaVie), [T2V-Zero](https://github.com/Picsart-AI-Research/Text2Video-Zero), [Latte](https://github.com/Vchitect/Latte) and [Animatediff](https://github.com/guoyww/AnimateDiff) below.

We show more metamorphic videos generated by **MagicTime** with the help of [Realistic](https://civitai.com/models/4201/realistic-vision-v20), [ToonYou](https://civitai.com/models/30240/toonyou) and [RcnzCartoon](https://civitai.com/models/66347/rcnz-cartoon-3d).

Prompts are trimmed for display, see [here](https://github.com/PKU-YuanGroup/MagicTime/blob/main/__assets__/promtp_unet.txt) for full prompts. ### 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](https://github.com/PKU-YuanGroup/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 [...]"

Prompts are trimmed for display, see [here](https://github.com/PKU-YuanGroup/MagicTime/blob/main/__assets__/promtp_opensora.txt) for full prompts. ## 🤗 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](https://github.com/PKU-YuanGroup/MagicTime) in Huggingface Spaces. ```bash python app.py ``` ## ⚙️ Requirements and Installation We recommend the requirements as follows. ```bash 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](https://drive.google.com/drive/folders/1WsomdkmSp3ql3ImcNsmzFuSQ9Qukuyr8?usp=sharing). Some samples can be found on our Project Page. ## 👍 Acknowledgement * [Animatediff](https://github.com/guoyww/AnimateDiff/tree/main) The codebase we built upon and it is a strong U-Net-based text-to-video generation model. * [Open-Sora-Plan](https://github.com/PKU-YuanGroup/Open-Sora-Plan) The codebase we built upon and it is a simple and scalable DiT-based text-to-video generation repo, to reproduce [Sora](https://openai.com/sora). ## 🔒 License * The majority of this project is released under the Apache 2.0 license as found in the [LICENSE](https://github.com/PKU-YuanGroup/MagicTime/blob/main/LICENSE) file. * The service is a research preview intended for non-commercial use only.
