VideoScore

This is the official repo for our EMNLP 2024 paper "VideoScore: Building Automatic Metrics to Simulate Fine-grained Human Feedback for Video Generation".

News

[2024-08-05] We released the Wandb training cruves of VideoScore and VideoScore-anno-only to help reproduce the training results.

Introduction

🚀The recent years have witnessed great advances in video generation. However, the development of automatic video metrics is lagging significantly behind. None of the existing metric is able to provide reliable scores over generated videos. 🤔The main barrier is the lack of large-scale human-annotated dataset.

🛢️VideoFeedback Dataset. In this paper, we release VideoFeedback, the first large-scale dataset containing human-provided multiaspect score over 37.6K synthesized videos from 11 existing video generative models.
🏅VideoScore. We train VideoScore (initialized from Mantis) based on VideoFeedback to enable automatic video quality assessment. Experiments show that the Spearman correlation between VideoScore and humans can reach 77.1 on VideoFeedback-test, beating the prior best metrics by about 50 points. Further result on other held-out EvalCrafter, GenAI-Bench, and VBench show that VideoScore has consistently much higher correlation with human judges than other metrics.
🫡Human Feedback for Video generative models. Due to these results, we believe VideoScore can serve as a great proxy for human raters to (1) rate different video models to track progress (2) simulate fine-grained human feedback in Reinforcement Learning with Human Feedback (RLHF) to improve current video generation models.

Installation

for inference

pip install -e .

for evaluation

pip install -e .[eval]

for training

git clone https://github.com/TIGER-AI-Lab/Mantis
cd Mantis
pip install -e .[train,eval]
pip install flash-attn --no-build-isolation
# then training scripts are in Mantis/train/scripts

Dataset

🤗 VideoFeedback VideoFeedback contains a total of 37.6K text-to-video pairs from 11 popular video generative models, with some real-world videos as data augmentation. The videos are annotated by raters for five evaluation dimensions: Visual Quality, Temporal Consistency, Dynamic Degree, Text-to-Video Alignment and Factual Consistency, in 1-4 scoring scale.
🤗 VideoScore-Bench We derive four test sets from VideoFeedback, EvalCrafter, GenAI-Bench and VBench respectively to curate VideoScore-Bench. VideoScore-Bench is composed of about 7,000 videos, covering both Likert-scale annotation and human preference data.

Model

🤗 VideoScore is a video quality evaluation model, taking Mantis-8B-Idefics2 as base-model and trained on VideoFeedback.
🤗 VideoScore-anno-only is a variant of VideoScore, trained on VideoFeedback with the real videos excluded.
