This is basically the same question you asked in the newbie forum. Please don't crosspost. See below... Well there can be a few different factors when deciding this. How many videos do you want on a single cd? How long are each? (See what I'm getting at). What I usually do is enter around 1000 for bitrate and see how big the resulting file is calculated at. Then decide if I want it to be bigger or smaller. It will also depend on what type and quality of audio you are using, mp3, aac, etc. Try this and see what bit/pixel values it gives you. Mac
