I just got access to Video Builder about a week ago and I have to say that it has been working pretty well for creating 6 second intro videos. They give you the option to do 6 seconds or 15 seconds, so it’s somewhat limited on the length, but for simple intros it’s perfect.
Pros: I love the the tool sits in my YouTube account and is connected to my channel.
Cons: I’m giving Video Builder a 5 because I think its marginal compared to the other software I have tested on this site. It’s free which is cool, but I have to be fair to the other apps here cause they are pretty innovative.
