Copyright is a minefield. It is a protection but when you spend two whole days putting a video together making Frankenstein dance to one of your tracks for a video and you do your research and yes Frankenstein 1931 Public domain, good to go only to find that Universal take your video down because since they started to remake Frankenstein films they used the original Lon chaney style Frankenstein so NOW it’s copyrighted by Universal. My video was up for 10 seconds before it was taken down. Tired and nothing to show for it. Lol. But that’s how it is now. You just can’t be to sure.
