Search two hour video for a specific five second clip
I can think you should try this project, https://github.com/nielstenboom/recurring-content-detector. I would recommend trying the Color Histogram or Color Texture Motion algorithms. The Convoluted Neural Network one is quite compute intensive and the results haven’t been that good for me. Since your looking for such a small clip, you might need to reduce the frame skip parameter to get more accurate timings.
