With your samples, Image Mode, 99%, Same Aspect/Rotated/Flipped, is finding the wanted dups.
But you're saying, even so, it is finding others outside of these pairs & including them with them?

Or did you just not set the % high enough?

Maybe the Image Mode scan does (automatically) ignore meta data, already?

Thanks for checking!

I thought I had run a 99% similar scan in Image Mode, but I turned off rotated and flipped. I'll try it with those on.

It was the similarity scan in Regular Mode that won't find them even with as low as 80% similarity (I ran a few further scans), but will find pieces of those two movies (I have both .mp4 files and .mp4.modd files that belong to the same movies) and consider them duplicates of each other.

Okay, my Image Mode 99% scan found 4 pairs, none of which were actual duplicates (so it didn't find either pair I gave you access to). But I see where my problem was: I had "Similar file names" checked. Apparently, that additional " (0)" or " (1)" makes the filenames less similar than "DSC01848.jpg" and "DSC01849.jpg", and enough less similar that it knocks them out of consideration. I reran it without "Similar file names" checked and now have all the duplicates. I just have to tread carefully through my duplicates to avoid deleting the ones that are very close but not actual duplicates.

I guess I was hung up on really wanting to find them by filename rather than by content, and didn't think to uncheck that box when trying scan variations. (In my defense, if I could have run a search structured to find the appended " (0)", I would have had all the duplicates right away and no worry about two different photos that are very similar! Since I know I often take multiple pictures of the same thing.)

Thanks for your help!
