For simplicity and effectiveness, let's outline a method using PyTorch and a pre-trained model. We'll use a model pre-trained on the Kinetics dataset, which is a common benchmark for video action recognition tasks. Specifically, we can leverage the SlowFast model, which has shown excellent performance on various video understanding tasks. Ensure you have PyTorch and torchvision installed. If not, you can install them via pip:

import cv2 import numpy as np

def prepare_model(): model = models.video.slowfast_r50_2x16x32_featurizer(pretrained=True) model.eval() # Set the model to evaluation mode return model 22241mp4

features = extract_features(model, frames_tensor) print(features.shape) You might want to save these features for later use: For simplicity and effectiveness, let's outline a method
