thanks for your comments.This was the first time I recorded I play as long as 3h.Do you have any advise on editing those big files in sony vegas if a client wants it on dvd?I mean do you convert those AVCHD files to something else before uploading it into your project file in sony vegas then edit it.The problem I had was I used two cameras.One HD and one SD.I thought I had to meet in the middle in order to get both qualities looking almost the same after rendering.Anyhow its just nice to be able to discuss these things for once with someone else and not pull your hair out on your own.Thanks again.
