Q: Unable to find "Movies" as shown in storage

Good Evening

I have used many different sweepers, cleaners etc to try and resolve this but have had no luck. I've used Omni Sweeper along with other software to sort it out but still can't find a resolution.

Every time I check my mac storage through "about this Mac", "Storage" it displays something like 100GB of "Movies" are taking up the storage, the problem is that I cannot find any of these movies anywhere. Omni Sweeper says I have something like 80GB in total on the whole Mac yet the storage says different. Can anybody help?
