What the Video Liberty project is: The main goal for the Video Liberty project is to promote sharing video content under open licenses. This means giving makers of original videos a way to find video content they can legally use in their own projects at no cost, as well as to give them a way to share their original footage for others to use, also at no cost.
What the Video Liberty project is not: The Video Liberty project is not any of these:
What the content is: A key element of other site types listed above is that they normally deal with finished video products. This doesn't imply that they are "polished" (some are, some aren't), but that the person who posted the video considers it "done." Compare that to the content handled by the Video Liberty project, which is more likely to be the "raw materials" from which finished video products can be created. This typically means higher resolution but minimal editing.
Where the content is: The Video Liberty project is not for hosting video files. There are other sites for that purpose. In the same way that you don't get a haircut from the Yellow Pages but you can use the Yellow Pages to find a barber, you won't download video content from the Video Liberty project but you can use it to find video to download.
Who the Video Liberty project is for: Since the main goal is not to watch videos, the people who will be most interested in the Video Liberty project will be those involved in some way with creating video content. This includes videographers, writers, musicians, photographers, and other original content creators and editors. This is a narrower audience, but it is one that is motivated to be actively involved and one that is not fully served by sites handling finished video products.
