What if slight changes have been made to the sheet? In one part, for example, there's a place where you need to hit two keys far apart at the same time but I couldn't find a way to do it, so I only played the one.
In another part, there were very minor mistakes, which I obviously corrected in my playing.
And in some of my videos are little mistakes like rarely pressing two keys instead of one or messing up the rhythm for a second. I do at least 3 takes for my videos, though, and they end up good, in my opinion. You shouldn't need to do a performance absolutely perfectly, I'd think.
