The political and societal consequences occurred because of the misinformation disseminated by the fake videos. To prevent these issues, automated approaches for deep fake detection are necessary. The deep fake video is detected in this work using hybrid deep learning. The main contribution of the proposed research is to determine deepfakes from videos, which aims to avoid the spread of malicious rumours. The differences between the real and deepfake videos are effectively identified through this developed approach, as they utilize the different features from the facial landmarks along with the eye blinks for determining the sophisticated fakes from the authenticated visual contents. The required videos are collected from the public databases. The frames are extracted from the collected videos. The attained video frames are given to the facial landmark detection process, where the coordinates of the eyes, lips, and nose are extracted. From these detected facial landmarks, the texture features, shape features, and the number of eye blinks are obtained for better detection purposes. The extracted features are integrated with the optimized weights for attaining the weighted fused feature, where the Updated Random Parameter-aided Fennec Fox Optimization (URP-FFO) is used for tuning the weights optimally. Each frame of 1-dimensional data forms 2-dimensional original video frames, which are taken as feature set 1 from the weighted fused features. The 3-dimensional data from the facial images is considered as feature set 2. The attained features are given to the Hybrid 2D-3D Convolution-based EfficientNetB7 with Attention Mechanism (HC-EB7AM) for differentiating the real and fake videos. The manipulated contents are easily identified by this approach. Finally, several measures are used for validating the performance. The potential strength of the proposed model is validated by the experimentation with the accuracy of 93.66% using dataset 1 and 94.38% using dataset 2, respectively. |  |\n\n1. Introduction  \nThe emergence of inexpensive devices like cameras, smartphones, and computers is the reason for the development of social media (Alnaim et al., 2023). The exponential growth of social media helps to share content very quickly, which provides easy access to the shared data (Tan et al., 2022). The enormous progress in machine learning and  \ndeep learning algorithms is used to detect manipulated video content for preventing the spreading of misinformation, which protects people from danger (Khormali & Yuan, 2024). The spreading of deep fake images in the modern world threatens society very seriously. Deepfake is represented as synthesized video or audio content generated via artificial intelligence (Park et al., 2024). The categories of deepfakes include swap-face, facial feature manipulation, and face synthesis (Guo et al.,  \nAbbreviations: URP-FFO, Updated Random Parameter-aided Fennec Fox Optimization; HC-EB7AM, Hybrid 2D-3D Convolution-based Eff","cbCaij47OTaEGH8Z","https://ap.wps.com/l/cbCaij47OTaEGH8Z","pdf",7995679,1,22,"English","en",105,"# Introduction\n## Deepfake background and risks\n## Deepfake categories and representation\n## Prior work and dataset limitations\n# Proposed approach\n## Video frame collection and feature extraction\n## Facial landmark and eye-blink based feature fusion\n## Optimized weighted fusion and HC-EB7AM classification\n# Experimental validation\n## Performance measures and results","[{\"question\":\"How does the method detect deepfakes from video content?\",\"answer\":\"It extracts video frames and derives facial landmark coordinates (eyes, lips, nose) plus eye-blink information.
