rwinn, thanks for checking our platform and for your patience waiting for the results. It's great to know your experience and the results you got (or lack of those :P). We'll check it and get back to you with some news.
I know you didn't ask for this, but I took the liberty to run the video you asked for through our data and here are the results [0]. As you can see, pretty decent amount of them found across many different sites. These results look much more impressive for massively viral videos, but even this paints an interesting picture.
Impressive results! Even where the original is distorted and mixed with other videos it's detected. I take it you use a different technique than spotter?
Thank you. Can't comment on their technology as I have no idea what are they using. Our service is very complex environment that consists of many different parts and pieces. We run at a huge scale (many thousands of servers) and indexed more than 4B videos. That allows us to do what you see above.
(we just launch the tool and it's still on Beta).
