So I'm authoring my first Blu Ray project shot originally on HDV and I'm wondering how I can make both a blu ray disc and a regular DVD without starting from scratch. Looking under Build - Format I see I can choose Blu Ray, DVD or Flash. I created this project originally for blu ray. It's about 3-hours long. When I switch the format to DVD it says it requires a 12.5 GB disc using the auto transcode settings. Normally I can fit 3-hours onto 1 dual layer DVD. I'm guessing it's trying to keep the native resolution of 1440x1080.
So my question is what is the best way to author both?
Thanks!
