Doubtful, gear wouldn't take up a lot of bytes. As for the video? I'd say, given the length, maybe about 150-200MB's? Gear, maybe... In total, about 400-500MB's? Know that I only have experience with this because I mod Skyrim (others too, but this game is the most prominent), and a lot of the mods on that game are not often as highly compressed as the content here. So, my knowledge is really quite limited, but those estimates should be relative in some way, perhaps not completely accurate, but it is just an educated guess.
