I am making a movie in sony video vegas, when i render it gets bad quality.
I am using the same settings as I have used before and didn't get bad quality,
this problem happened about two days ago, I have tried reinstalling and all that but it doesn't work, still getting crappy quality!

Can anybody help me? if you have experienced the same could you explain to me what you did?

thanks for your attention.

I am not very good in english, because I am from Norway.
