Are there any Open Source Digital Video Fingerprinting initiatives?
ie: Something that could compare two video files of disparate quality but indicate they are of the same event, program etc.

A:
If you consider video as a sequence of individual frames and compare key frames, then these previous answers provide some suggestions / algorithms / places to start:
Image fingerprint to compare similarity of many images (See in particular @GalacticCowboy's answer as he may have done what you are looking for.)

That is suboptimal for several reasons: different videos can have different frame rate, scale, aspect ratio, brightness, saturation. All these factors render per-frame image comparison useless.

I am not aware of open-source - but you are basically searching for this:

They sell the code that lets you do what you are looking for.
