Blu-ray mastering question
Ok so I uderstand how DVD authoring/master and what not works...is the process different for Blu-ray?
Meaning, is there a totally different transfer process to do it? Pardon my stupidity, but it seems like if you did the DVD transfer Blu-ray should be the same only bigger, no?

are you referring to creating the transfer of the film for DVD/BD or authoring the disc itself (transfer, menus, etc)?
as far as transfers are concerned, both a DVD transfer and a BD transfer are created from the same master, but the transfer itself is different, because of the different codecs and bitrates.

Guess I got my terms wrong...I always assumed that authoring encompassed the transfer. I guess not.
Anywho, yes transferring was what I was looking for.

Most films are transferred to an HD master tape, which is then used for both the Blu-ray and downscaled to Standard Definition for the DVD. So yes, they only have to transfer it once. However, the digital video then needs to be compressed separately for each format. Then you have additional expenses involved in the authoring of each (creating menus and Java interactive features, adding AACS and BD+ encryption, etc.).
Most of the major studios have been archiving HD masters of their films for the past decade, but that doesn't mean that every one of those masters is going to get cranked out onto Blu-ray right away.

Follow up question, is Blu-ray downscaled as well? I was reading that a lot of films are scanned @ 4k and downscaled to 1920X1080, is that accurate?

CRT's provided the best pricture of all the TV formats with regards to color accuracy. Since CRT's are going the way of the Dodo Bird, many of the post houses are transitioning to LCD and Plasma flatscreen. Some are even using rear-projection DLP's for their QC process.
Sony recently introduced a reference level LCD flatscreen which goes for around $8000, specifically aimed at post-production.

On the 'Grave of the Fireflies' DVD, there's a bonus feature about the video transfer, where the operator proudly demonstrates flipping on the switch for edge enhancement to "sharpen up the picture". I'm sure it looked fine on his small monitor, but blowing that picture up on a projector is an entirely different story.

Yeah, I didn't notice a difference either.
