In the case of The Godfather, that is exactly what they did. The rescanned it and completely restored it, then they produced DVDs and Blurays from the same high Definition master (much higher than Bluray allows for).

No studio of any note will take a DVD version, upscale it, and release it as Bluray. When mastering for Bluray, the film is scanned at higher than Bluray resolution, processed in whatever way is deemed necessary depending on the budget for the release, the quality of the source, and the perceived value to the studio, and then encoded multiple times for dofferent uses. They will encode it to DVD spec for DVD, Bluray spec for Bluray, and may even encode a lower spec version for digital download.

While many studios made HD scans when preping work for DVD release, knowing that something better was coming, many are finding that they need to scan the prints again to reach the level of quality that is expected in a modern release.

Bottom line though, they do not start with a low quality source and build up. The start with a high quality source, and go down from there.

What's kind of a drag though is some of the clean-up they are doing. Many of the older films are losing their original flavor (and some detail at times) as film grain has been deemed unacceptable for the new breed of movie watchers. A similar phenomena is apparent with 120Hz LCD's. Older great films just look different.

A good restoration should be just that - restoring the film to it's former glory. The Godfather is a good example of a digital restoration done right, as is Casablanca. One of the most astounding I have seen is Rear Window, not only because the end result is so incredible, but also because it was a chemical restoration, not a digital one.

I can't stand grain in a film,I wish all transfers were done to THX standards by Lucasfilm et al.I don't like what Turner did to the old B&W classics,colorizing looks awful*.
Transferring a film is laborious and most films look great on Blu-ray while some early releases don't look any better than DVD.

*I do give Turner credit for saving the old films and restoring them for future generations.

A rather odd post, you "can't stand grain in a film" yet you didn't like what Turner did to old classics? As far as George Lucas, I wish he had stopped making movies after Howard The Duck, it was all down hill after that.

Love grain in film - I purposely add some every encode despite the added bitrate requirements. It gives it that classic cinematic effect.

But hey, to each their own right?

MysticE,
George Lucas owns THX,ILM and of course Lucasfilm.You may not care for his films but THX and ILM have advanced the art of filmmaking.
Turner colorized the old MGM catalog which I don't like but at least he cleaned them up,there's a difference between color and grain.

Exactly!!!!
Cleaning and restoring is one thing, colorizing old B&W movies is probably one of the most worthless things to have ever been done!!!

Maybe moviemaking would be a more appropriate term.

AFTER???

To each his own, as I think it is VERY worthwhile, as long as it's done tastefully and with the full cooperation of the rightsholders/creators and with high quality and preservation foremost in mind. Unfortunately, there are a number of examples where the process was undertaken without fulfilling those requirements...

Well, all the one's i have sampled never looked right & the original B&W version is preferred over some crayola coloring hack job

But really, they never ever look right 8)
