Hi,
Thanks for maintaining the Awesome Deepfake Detection repository.

I would like to kindly suggest adding our recent CVPR paper on the first dataset for action-level video deepfake detection.

Title: ActivityForensics: A Comprehensive Benchmark for Localizing Manipulated Activity in Videos
Venue: CVPR 2026
arXiv: https://arxiv.org/abs/2604.03819
Code and Dataset: https://activityforensics.github.io

We believe it could be a useful addition to the repository.
Thanks again for your effort in maintaining this valuable resource!
