Stop Motion tips please?

I'm in the process of making stop motion animation - taking photos, adding audio. I've been using Windows Live Movie Maker and standard Movie Maker, but finding the quality of finished product not all that great. I take the pics on a Nikon DSLR, so photo quality is really good. I've recently used Sony Vegas Pro and find I can't render the video with pics and audio as the audio gets messed up. Any tips on good programs to use for Windows or any tips in general… Would be much appreciated:-) Plus any tips on uploading to YouTube in good HD quality… I know I'm asking a lot!

If you have an iphone get the stop motion app! Really really good but
Its some what pricey like 5 bucks total but you can upload pics and studf and its great!

Nice to see some avid photographers wanting to know more.

Production tips: take as many stills as possible for effective stop motion
Editing: Software (adobe premier pro CS4 or higher), then export in h.264 HD at 1920x1080 resolution
Youtube: just click upload and click your file, youtube handles the rest (aslong as you render in a HD format)

hope this helps!
