ChronoMagic-Bench: A Benchmark for Metamorphic Evaluation of
Text-to-Time-lapse Video Generation

If you like our project, please give us a star ⭐ on GitHub for the latest update.

This repository is the official implementation of ChronoMagic-Bench, a benchmark for metamorphic evaluation of text-to-time-lapse video generation. The key insight is to evaluate the capabilities of Text-to-Video Generation Models in physics, biology, and chemistry by enabling the generation of time-lapse videos, which are characterized by rich physics priors, through a free-form text prompt.

💡 We also have other video generation project that may interest you ✨.

😮 Highlights

ChronoMagic-Bench can reflect the physical prior capacity of Text-to-Video Generation Model.

📣 Overview

In contrast to existing benchmarks, ChronoMagic-Bench emphasizes generating videos with high persistence and strong variation, i.e., metamorphic time-lapse videos with high physical prior content.

We specifically design four major categories for time-lapse videos (as shown below), including biological, human-created, meteorological, and physical videos, and extend these to 75 subcategories. Based on this, we construct ChronoMagic-Bench, comprising 1,649 prompts and their corresponding reference time-lapse videos.

🎓 Evaluation Results

We visualize the evaluation results of various open-source and closed-source T2V generation models across ChronoMagic-Bench.

🔨 Usage

Use ChronoMagic-Bench to evaluate videos, and video generative models.

Prepare Videos for Evaluation

The generated videos should be named corresponding to the prompt ID in ChronoMagic-Bench and placed in the evaluation folder, which is structured as follows. We also provide input examples in the 'toy_video' .

# for ChronoMagic-Bench
`-- input_video_folder
    `-- model_name_a
        |-- 1
        |   |-- 3d_printing_08.mp4
        |   `-- ...
        |-- 2
        |   |-- 3d_printing_08.mp4
        |   `-- ...
        `-- 3
            |-- 3d_printing_08.mp4
            `-- ...
    `-- model_name_b
        |-- 1
        |   |-- 3d_printing_08.mp4
        |   `-- ...
        |-- 2
        |   |-- 3d_printing_08.mp4
        |   `-- ...
        `-- 3
            |-- 3d_printing_08.mp4
            `-- ...
            
# for ChronoMagic-Bench-150
-- input_video_folder
    |-- model_name_a
    |   |-- 3d_printing_08.mp4
    |   `-- animal_04.mp4
    |   `-- ...
    |-- model_name_b
    |   |-- 3d_printing_08.mp4
    |   `-- ...
    `-- ...

The filenames of all videos to be evaluated should be "videoid.mp4". For example, if the videoid is 3d_printing_08, the video filename should be "3d_printing_08.mp4". If this naming convention is not followed, the text relevance cannot be evaluated.

Get MTScore, CHScore and GPT4o-MTScore

We provide output examples in the 'results'. You can run the following commands for testing, then modify the relevant parameters (such as model_names, input_folder, model_pth and openai_api) to suit the text-to-video (T2V) generation model you want to evaluate.

python evaluate.py \
  --model_names test \
  # or more than one model
  # --model_names test abc  \
  --input_folder toy_video \
  --output_folder results \
  --video_frames_folder video_frames_folder_temp \
  --model_pth_CHScore cotracker2.pth \
  --model_pth_MTScore InternVideo2-stage2_1b-224p-f4.pt \
  --num_workers 8 \
  --openai_api "sk-UybXXX" \

If you only want to evaluate any one of the metrics instead of calculating all of them, you can follow the step below. Before running, please modify the parameters in 'xxx.sh' as needed. (If you want to obtain the JSON to submit to the leaderboard, you can organize the output files in MTScore / CHScore / GPT4o-MTScore according to 'results' and then proceed with the following steps.)

# for MTScore
cd MTScore
bash get_chscore.sh

# for CHScore
cd CHScore
bash get_mtscore.sh

# for GPT4o-MTScore
cd GPT4o_MTScore
bash get_gp4omtscore.sh

Get UMT-FVD and UMTScore

Please refer to the folder UMT for how to compute the UMTScore.

Get File and Submit to Leaderboard

python get_uploaded_json.py \
  --input_path results/all \
  --output_path results

After completing the above steps, you will obtain ChronoMagic-Bench-Input.json, and then you need to manually fill the JSON with UMT-FVD and UMTScore (as we calculate them separately). Finally, you can submit the JSON to HuggingFace.

📑 Benchmark Prompts

We provide prompt lists and the reference videos of ChronoMagic-Bench at Hugging Face. You can use this to sample videos for evaluation of your model.

🏄 Sampled Videos

To facilitate future research and to ensure full transparency, we release all the videos we sampled and used for ChronoMagic-Bench evaluation. You can download them on Hugging Face. We also provide detailed explanations of the sampled videos and detailed setting for the models under evaluation here.

🐳 ChronoMagicPro Dataset

ChronoMagic-Pro with 460K time-lapse videos, each accompanied by a detailed caption. We also released the 150K subset (ChronoMagic-ProH), which is a higher quality subset. All the dataset can be downloaded at here and here, or you can download it with the following command. Some samples can be found on our Project Page.

huggingface-cli download --repo-type dataset \
--resume-download BestWishYsh/ChronoMagic-Pro \  # or BestWishYsh/ChronoMagic-ProH
--local-dir BestWishYsh/ChronoMagic-Pro \  # or BestWishYsh/ChronoMagic-ProH
--local-dir-use-symlinks False

Please refer to the folder Multi-Aspect_Preprocessing for how ChronoMagic-Pro to process this data.
