Too Many False Positives With Ad Files

Video Duplicate Checking:
Currently it seems czkawka checks the start of the video and end. However if there's ad's or a series intro at the start, czkawka marks them as possible duplicates. Would it be possible to extend where czkawka checks the video file (after say 2-3 min in and back from the end?

Add Non-Duplicate file tags to cache:
As with the above problem, consistently checking every false positive manually is time consuming (if you run czkawka multiple times getting the same false positive). Could you add an option to select the file(s) and add that to the cache hash check as non-duplicates so it doesn't come up again (between those files). Or could store it in a .config file

Add Thumb Nail Preview For Video Duplicates (as a toggle option in settings if users want to use it or not)

Bug: In "Similar Videos" option, when you hover over "Similarity" slider, the information that comes up is about similar music files - not a description of similar video settings
