--- Comment #17 from Poz <poznia...@gmail.com> --- Wow the discussion here is fantastic. Thank you for the time and thought! So yes, the approach I suggested of just using the thumbnails is clearly not robust enough given the wide array of video content out there. I think a lot of the problems come from very uniform videos, for example standard intros or outros. My case has very non uniform videos (without any intro or outros) where I can run through windows explorer and find duplicates myself from simply looking at the thumbnails so I know at least 20% are duplicates just from simple observation. The problem is that it is to much to go through that many files and click each one individually. I have used Digikam before on photos for duplicates and was amazed at how well it worked so naturally I thought, 'man, I wish I could get digikam to access these thumbnails for me, I could get rid of +95% of these duplicates in a day'. I know there could be false positives, but I could live with 1% or something like that. To further get rid of false positives there could be a video length option of +-X seconds (default at 2 or something). I currently use http://www.alldup.de/alldup_help/alldup.php The content method works very well, I would say less then 0.001% false positives. But it misses so very very much. It can take up for 48 hour to run, but builds a database so it only compares new files added into the search. I even use the file size method, for large files, this works very well. Smaller files (<10 mb?) tend to have more false positives. Unfortunately due to different compression and file types this does not catch them all either. I think in the end, until computer hardware is faster, video duplicate searches will require a number of different methods and some user input. Until then that is what we have to work with/ around. I was just hoping for another way to slim down on this video database. Thumbnail seemed like low hanging fruit. -- You are receiving this mail because: You are watching all bug changes.
