Video Dedup


This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.

This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.

Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.

Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.

Please do not email me about this project without reading the disclaimer above.

If you have ever watched YouTube, you will notice many videos are compilations of clips from other sources. Nearly always they contain duplicate clips. This tool detects the duplicates and automatically removes the shorter one. This is more difficult than it sounds. You must detect the boundaries between clips. You must sample the clips to see if you can find a duplicate clip, that may have material chopped or added to either end.

Sometimes duplicate clips have different colour correction, and different original resolution. It would be very difficult to detect such duplicates, so you probably should not even bother trying until you get the basic version of the program working.

Rather than making a version to edit every different video format, pick one, and team up with video converter program to convert to and from your chosen format.
