I had a great week. The duplicate filter now supports filtering by pixel duplicates, and videos now fit better in the media viewer.
better duplicate search
Now we have pixel duplicate data stored in the database, I can search it. The duplicate filter page now has a dropdown that lets you select 'must be pixel dupes', 'can be pixel dupes', and 'must not be pixel dupes'. It does exactly what you think, and with luck it should be pretty fast no matter what you select.
Note that you may not have all your old pixel dupe data calculated yet. I started it for everyone last week, but even if it is doing 10,000 files a day, if you have a big client it will take a little longer. It may also still be working on the ICC profile queue. Hit up database->file maintenance->manage scheduled jobs to see how it is doing. You can rush it there if you like.
