On a serious note, I'd prefer to see a polished video that's a few weeks behind schedule, as opposed to a bunch of videos that were rushed for the sake of uploading content on the channel
I actually think a video a week is a little optimistic. I think I'd rather see monthly content, at least to start. I think this is how most people start out on Youtube, and other video production websites. Bring out the best quality possible, don't go in making schedules that will be hard to keep too, and keep it consistent.
