I have some most likely rare video clips that I believe are early HD video tests which I pulled from a hard drive of some test equipment. I would like to know more information about these clips but this seems like I'm starting to head into the identification territory.
I think this could be a very interesting discussion because I'm also interested in the history behind them and if we were able to find out what they were I think it could bring up an interesting discussion on the history and technical aspects of the video clip.
In addition because I have the clips if we find it, is something that can be answered objectively because I'd gladly upload screenshots and even the clip if allowed. I'm not just posting a vague description of something I saw in the 1980s as an example.
I've tried over the years to find more information about these clips including reverse image searches, and when they talk to type in what they are saying and other search queries related to it. For one of them I was even able to identify some of the buildings featured in the video but I was never able to identify the title of many of them despite extensive search engine effort.
I personally believe this would lead to a high quality discussion.
