An anonymous reader writes: Mitch Martinez creates high-resolution stock video footage, and then licenses it out to people who need footage to go along with their creative projects. He has written an article at PetaPixel explaining his bizarre interaction with Sony Music Entertainment, and the hassle they put him through to fix it. Martinez licensed one of his videos to Epic Records, and they used it as background for a music video on YouTube. Less than two months later, his original video on YouTube was hit with a copyright claim from Sony. After figuring out that Epic Records was a subsidiary to Sony, he disputed the copyright claim — which is usually the end of it. But after reviewing the videos, Sony rejected it, saying their claim was still valid. Martinez then tried to contact the person at Epic Records to whom he issued the license. None of his emails got a response. Then he had to get in touch with Epic's legal department. After a lengthy series of emails, voicemails, and phone calls, he finally got somebody to admit it was his video. It still took a few more calls to work out the details, but the company finally released the copyright claim. Martinez concludes by offering some tips on how to resolve such claims.
