I've Got It
YouTube has an option that lets you add a short clip to your future and past videos. But it only lets it be 3 seconds or under. And seriously this is for your own good. Anything more than that can get repetitive and annoying.
Really? I never knew that such a feature exists. That is pretty cool and useful.
Now if only they had a way to save templates for annotations to use for future or a way to normalize volume of soem uploaded videos by small amounts for fine tuning sometimes. Like +/- 1 db.
