There are a few mistakes here, and as I’ve yet to figure out how to edit videos properly (I’ve only managed to hang my video editing software so far), they’ve stayed in; I’ll do another video correcting things.
The pagelist creation process is probably the hardest bit for beginners to Wikisource, and it’s something we need to work on. Metadata copying, on the other hand, mostly works fine (of course, we should not be _copying_ the metadata, but that’s another story).
