I'm going to ask my questions again in a separate thread, because they were getting lost in the quite interesting discussion of which films are or are not in PD. Anyway, I recently purchased the 50 Movie Pack Family Classic collection from Treeline Films. It's quite a hodge-podge of PD films. I haven't watched all the movies yet, but those I've seen are definitely of mixed quality ('Til the Clouds Roll By is OK, but Let's Get Tough is unwatchable, for example). Seeing all these movies in one set made me wonder: 1. Where does someone go to get all these movies and how would a reputable company legitimately obtain the highest quality version? 2. If someone spent the money and effort to restore some of these films, what's to keep someone else from using and selling that copy. (From the other thread, it seems like this is an open question.) 3. If someone used a purely automated restoration technique (i.e. in the most extreme case, pushed the Restore button and came back a week later to look at the results), would that version be copyrightable? Could one argue that the creation of the restoration software was in fact the creative effort that caused the resulting version to be copyrightable? I know there are a lot of talented, knowledgable people who frequent this forum and I'd value your input.
