2025 1M-Deepfakes Detection Challenge

ACM Multimedia 2025 Oct 29, Dublin

The new 2025 challenge builds on the successful 2024 challenge to focus on the deepfake detection and localization. This year the challenge is based on new AV-Deepfake1M++ (paper) containing over 2 million samples!

Task 1: Video-Level Deepfake Detection

Given an audio-visual sample containing a single speaker, the task is to identify if the video is a deepfake or real.

Task 2: Deepfake Temporal Localization

Given an audio-visual sample containing a single speaker, the task is to find out the timestamps [start, end] in which the manipulation is done. The assumption here is that from the perspective of spreading misinformation.
