user23726: I have a lot of video files but also a lot of duplicate with different encoding differences (eg 720p and 4K versions). I wasn't able to find an open source solutions. I tried a Windows paid program who did half the job.

user36321: In fact, there are mostly 3 software for finding duplicate videos.

Video Compare https://www.video-comparer.com
Duplicate Video Search  https://duplicatevideosearch.com
Duplicate Media Finder (my favorite) https://duplicate-media-finder.kdo-rg.com

All of them use fingerprints.
