Today I uploaded the same video to YouTube and Photobucket. For the soundtrack I used a short piece of Ravel's Bolero. This was recorded using a MIDI file released into the public domain on a bulletin board many years ago - before the world wide web took off. This I played through my Roland keyboard which has sampled sounds of real instruments. Good as they are it is still possible to detect they are not played live by a human.
YouTube sent me a mail saying it may be copyright of EMI though it did load and display.
Photobucket refused to load and save it as it alleged it was copyright material.
Two examples where very aggressive auto detection software is being used to arbitrarily detect copyright material. I have mailed both companies and it will, possibly, be interesting to see what their responses are.
