Help needed with a youtube project

Hello! Long time no see again. How is everybody? :)

I've started a youtube channel promoting breakbeat hardcore music. You can find the channel at http://www.youtube.com/bbhccollective - it's all 100% legit, artist permissions and buy it links, soundcloud and event promo too. It's all for the love of the genre.

Anyway, I thought this would be a great place to ask on the technical side of things. I'm currently upping movies using Windows Live Movie Maker and editing using Cubase (which I'm fine with.) However, support's growing quite fast, and I think I'm definitely in need of some better video software.

What I'd like is something that can batch produce videos for youtube - I use the same logo and fade-in effect on every video, just a different audio clip on each, and then upload to youtube. Windows Live only lets me do one at a time, and it's quite time consuming.

Any ideas? :) Thanks!
