Video classification is an important task in computer vision, with many applications in areas such as surveillance, autonomous vehicles and medical diagnostics. Until recently, most methods used 2D convolutional neural networks (CNNs) to classify videos. However, this approach has several limitations, including being unable to capture the temporal relationships between frames and being unable to capture 3D features like motion.  To address these challenges, 3D convolutional neural networks (3D CNNs) have been proposed. 3D CNNs are similar to 2D CNNs but are designed to capture the temporal relationships between video frames by operating on a sequence of frames instead of individual frames. Moreover, 3D CNNs have the ability to learn 3D features from video sequences, such as motion, which are not possible with 2D CNNs. In this blog post, we will discuss how to classify videos using 3D convolutions in Tensorflow. We will first look at the architecture of 3D CNNs and then discuss how to b
