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)

Use a 3D CNN like I3D or VideoMAE which processes temporal data. 3. Pre-process the Data You can average the vectors from all sampled
