well, i tried my hand at Adobe Premiere for the very first vid...and, while it DID offer me more control, that program is really big and i don't think my processor or my memory is big enough to really work it correctly. so, this is what i've found is working for me:
1) i put down my video, transitions, effects and narration down in MovieMaker and publish it.
2) i then load that into Adobe Premiere and lay down a music track then use Premiere's cool 'volume control' to master all three audios: video audio, narration and music. I then publish it again.
3)THEN, i take that version...run it through MovieMaker AGAIN to condense it a bit more and it's ready for YouTube.
It may seem like a strange process but these are beginning to really look good. Here's a question: is the narration annoying?
