Yesterday i upload two video on youtube, but after a while server say me one of the file is copyrighted (and give me exact file information i never provide) and cannot be inside their database .... but the another file (same kind, same extention only content change ) had no problem....

these file are two .mov , i checked them (binary stuff and gspot tool) but they dont seems have meta data information inside of them .....

Someone reported it.

possible , even but seems strange since it comes 1 minute after upload and is not real protected stuff (5min of funny stuff made by a tv channel in 2000)


also error message contains real name of it (so maybe user who reported it either a youtube admin made some search)

pwn3d by youtube. If I were you I'd cry.

Open Final Cut Pro --> insert video and audio stream --> export --> upload --> done.

you know youtube has some checksum check, do you?
Maybe someone uploaded it before and it got purged so the video can't be reuploaded unless you reencode it

even if you reencode it, a checksum calculation may use video contents thus a clip match can be made even when all the meta information is lost. more likely, for copyright protection people use invisible watermarks added upon their videos so they can check whether another video has the same watermark or not. thus, even if you record the video with a hand camera while it's being played on your monitor and spread it, there is the possibility it can be detected. an invisible yes/no load on video works quite well and robust to most imaginable attacks.

You you reencode the video the data will be different so the checksum will also be different.

not when the checksum is computed over the video content (imagine: the checksum is the sum of numbers on shirts of football players on a football match, in reality it's not this semantic dependent. think of color layout, segments etc.)

they have the hardware power to do it after all... keep in mind they transcode every fucking video they get...
