I'll use whatever media is compatible and correct. But first I need the recorder. So I'm seeking knowledge on an HD and/or BlueRay recorder that's compatible with my hardware, software and HDV 1080i/Quicktime video files. Once I get the recorder, then I'll worry about the media.
Firstly I import into my edit system what ever it is you want to put on to DVD (for standard def, as has been explained, you need Blu-Ray for HD).
I make a programme from the media, export it as an Apple ProRes QT .mov file and take that file into BitVice for encoding. I then use Studio Pro to make a .mov from the resulting compressed file and burn the disc in Toast Titanium, all done on a MacPro, (the older one, not the very latest).
For Blu-Ray I can use Toast directly from my exported file, provided it's in HD. All my material is 1920 X 1080i and the discs look great and stand up well even in a cinema.
For burning your DVD's you can use the burner in your Mac, for BD's you'll need a stand alone burner and mine is a Lacie.
