: These capture motion and "how" things move across frames. Tools like Deep Feature Flow (GitHub) use a framework to propagate feature maps between key frames, which is significantly faster and more accurate for video recognition than per-frame analysis. mfnweB4.mp4

: If you are analyzing the file for security or origin, you can use the MP4 Tree Network (MTN) . This approach uses Graph Neural Networks to extract semantic embeddings from the MP4's internal tree structure (metadata) without needing to process actual video pixels. How to Extract Features Manually This approach uses Graph Neural Networks to extract

: These represent "what" is in each frame (objects, scenes). You can use a 2D Easy Video Deep Features Extractor (GitHub) to run a network like ResNet or VGG on individual frames and save the results as a .npy (NumPy) array. mfnweB4.mp4
