| | Posted: | | | | @ mdnitoil: technically you're correct, but beyond a certain point you are only recording the shape of the film grain and not adding useful new information. @ Skip: Older film stocks by-and-large are inferior to modern ones, but they still held a lot more information than SD DVD can render. Read this review of Casablanca, for instance. |

| | Posted: | | | | I know that, Ace and as I noted Casablanca was one of those films that has undergone a fairly extensive restoration, not as extensive as GWTW, which was the largest "overhaul" I am aware but certainly on a par with say. My Fair Lady. but even so, for every film that has undergone some form of restoration there are dozens if not hundreds that have not. Take, for example, the existing negatives for Steve Reeves' Hercules, to try and take the existing to Full1080P would be an utter waste of energy and money, can it be restored, to some degree yes, how much...I don't know...I don;t have access to the existing raw materials, I know what the state of the most recent prints are.<sigh> Will it be restored, someday maybe, but it has got to be low on the priority scale for such treatment..

I could be remembering this wrong, but I thought to have read that hidef titles are in fact never anamorphic...
Exactly. As said before: anamorphic is a crutch for the line-based SDTV-technic and the whole 4x3 vs 16x9 mess.
HDTV is a pixel-based technic with fixed resolutions. Whatever you try to gain on resolution on the y-axis you would lose on the x-axis.
cya, Mithi Exactly NO Blu-Ray or HD DVD title should have the anamorphic box checked. The exception would be combo HD DVDs, where the DVD side might have it. | | | | "This movie has warped my fragile little mind." |

Skip While I'm not sure about the original Hercules, which seems to have fallen into PD hell, the sequel Hercules Unchained is available on a beautiful anamorphic widescreen German disc, so there are some spectacular elements for it at least that would certainly benefit from an HD transfer. I'm told there was also an attractive French version of Hercules, but I haven't seen that so I can't comment on it. | | | | "This movie has warped my fragile little mind." |

| | Posted: | | | | Gard: I can only hope for a Region 1 release of what you mentioned. I have heard of a rather spectacular Italian print as well. But right now as you noted we are in PD hell on this and many others.  Skip | | | ASSUME NOTHING!!!!!!

| | Posted: | | | | @ gardibolt: why none? I'd say all hi-def releases should be marked as 16x9 enhanced as all high-def formats use a 16x9 frame. It would prevent the report oddness I was talking about. |

@ gardibolt: why none? I'd say all hi-def releases should be marked as 16x9 enhanced as all high-def formats use a 16x9 frame. It would prevent the report oddness I was talking about. DVD is native 4x3 (720x480 for ntsc) HD is native 16x9. A 16x9 enhanced/anamorphic DVD is still 720x480, they take the original 16x9 source and squeeze it to 4x3 so it will use the full resolution of the DVD (nothing wasted on black bars), the 16x9 TV then expands the image back to 16x9. The same anamorphic process is used on film to get a wide screen image onto 35mm film using a special lens on camera and projector (ie Panavision). HD is native 16x9 - 1920x1080, there is no anamorphic squeeze needed. So NO hi-def release should be checked enhanced. | | | | Tom. |

| | Posted: | | | | There's nothing anamorphic about HD discs. I see no reason to mark them as such. | | | Get the CSVExport and Database Query plug-ins here.

| | Posted: | | | | This really should be called 16:9 widescreen anyway. Anamorphic is a misnomer that should really only be used for lenses. Neither DVD aspect ratio uses square pixels in NTSC or PAL.
So what I want to see is the video options expanded to 480/NTSC, 576/PAL, 720p, 1080i and 1080p, with the latter three only being an option on hi def formats and 16:9 being optional on the first two, mandatory on the last three. |

That would simply be wrong. At the moment we capture "16x9 enhanced" DVDs, because those have a better picture quality (theoretically) but there simply is no such enchancement in HD DVD or BluRay. All(!) HD-Media have an aspectratio of 16:9, no matter what. If the movie has a different OAR black bars or pillars are included, as was the case in SDTV. cya, Mithi | | | | Mithi's little XSLT tinkering - the power of XML --- DVD-Profiler Mini-Wiki |
