Since a video is a sequence of images, you first need to sample frames. For a 5.75 MB file (likely a short clip), sampling or taking a fixed number (e.g., 16 frames) is standard. 2. Select a Pre-trained Model

import torch import torchvision.models as models import torchvision.transforms as T from PIL import Image import cv2 # 1. Load pre-trained ResNet model = models.resnet50(pretrained=True) model = torch.nn.Sequential(*(list(model.children())[:-1])) # Remove last layer model.eval() # 2. Define Transform preprocess = T.Compose([ T.Resize(256), T.CenterCrop(224), T.ToTensor(), T.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225]), ]) # 3.

Subtract the mean and divide by the standard deviation (specific to the dataset the model was trained on). Since a video is a sequence of images,

You can average the vectors from all sampled frames (Global Average Pooling) to create one unique "fingerprint" for the entire file. 5. Implementation (Python Snippet) Select a Pre-trained Model import torch import torchvision
