Since we keep track of audio codecs, why not video?  Also, this could be used to list resoltion as there's no rule that Blu-Rays must be 1080p so we'll likely see some that aren't in the future.

I like the non-1080p list part particularly.
With every passing hour our solar system comes forty-three thousand miles closer to globular cluster M13 in the constellation Hercules, and still there are some misfits who continue to insist that there is no such thing as progress.

I just found a related issue: 16x9 should be force-checked on all HD formats.  I just did a search for non-anamorphic widescreen releases and found my list was half Blu-Ray.

I would beg to differ with you on this, Ace. And good to you see you again. There probably are not very many yet, but there will be Academy Ratio and 1.33:1 releases done on BD and they aren't going to be 16x9, no matter what.

I'm fairly certain that 1080p academy ratio movies are just pillarboxed in a 16:9 frame.  At least, that's how Casablanca was handled on HD DVD.  Granted, you can put 480p 1.33:1 material on a Blu-Ray, though it doesn't make a lot of sense to so at the moment except for special features.  I revise my statement to say we should have video format options and 16x9 enhancement should be force-checked for anything that's 720p, 1080i or 1080p.

It's good to be back.  It seems most of my major annoyances with the program (like box set and TV handling and actors) have been fixed, but I can still pick nits as I find them.

I could be remembering this wrong, but I thought to have read that hidef titles are in fact never anamorphic...

If my memory served well, then I guess it would mean the filter in program must be adjusted somehow to cope with this problem. (Right now I have no idea what that could actually mean or what filtering logic would be required to allow this.)

That's correct AIUI; I believe there is no support for non 16:9 ratio images in the HD standard; it's not possible to shoot in HD in other than 16:9 so 4:3 images will have to be pillarboxed
It is dangerous to be right in matters where established men are wrong

Agreed. HD media is a 16:9 format. In order to maintain OAR, pillarboxing or letterboxing will be present on non 1.78 aspect ratio material.

Gracious, Ace. you couldn't be moire wrong. God forbid i put any ideas into the sick minds in Hollywood. Since MOST of the older films or especially TV are not likely to translate real well to 1080P because of the limitations of the older film stock and condition. We could, for example, take an entire Boxset and distill it down to a handful of discs. Or imagine, if you will, The Complete Series of Title of Your Choice, instead of being maybe 40 or 50 Discs, can nw be reduced to what... 6 or 7.

I am now going to go wash out my mouth for giving ideas to Hollyweird.<gasp>

Skip,
It's you who is dead wrong on this. 35mm Film stock, which is what the vast majority of Hollywood movies were filmed on has a scan limit of 4k (4096 pixels wide). HD, which at 1080x1920p, is even under 2k (2048 pixels wide), there is alot more detail on the film than what you are seeing even at 1080p. Even TV series which were many times shot on 16mm, which is half of a 35mm frame, still has a maximum 2k resolution. If they were shot for 1:33, when they are transferred to HD, they will have black pillars on the side as part of the picture, much like early DVDs did before the studios started doing anamorphic transfers of widescreen material.

Not to put too fine a point on things, but when your source is analog, you can never equal that source resolution in the digital domain...by definition.  As a result, 1080P, or for that matter 1 billion P, would still result in improvement to older films than current lower resolutions.  I'm by no means an HD evangelist, but the suggestion that older films don't benefit from HD is a myth.  It's both technically wrong, and anecdotally wrong based on the reviews of Warner's HD version of "The Adventures of Robin Hood."

DOH, beaten to the punch.

In theory you are correct, cmae. The reality is another story entirely, many of the older films I have seen transferred to some form HD, not all, I wouldn't have in my library. They aren't worth the investment, whether it is film stock or condition of same I don't know since I am not directly involved in the industry. A Hi-Def transfer i have seen of Grease for example is almost obscene in the amount of film grain revealed in Hi-Def, it so bad it is a distraction from the film.

Some older films that have undergone major restorations such as The Searchers and GWTW should fare really well, I know The Searchers was done but I haven't reviewed it yet. But many other films will probably not fare as well, I can't speak to the new computer restorations taken to hi-def since I haven;'t seen one yet, they might work out OK.

Yes, I agreee, it really all depends on the quality of the Hi-def master. I was watching the first Die Hard on Blu-ray with some friends on Christmas, and one who is a film director, and notices thing like this thought that the transfer was not very good and looked "smudgy" as he put it. I didn't notice it even while looking for it. I would bet that Grease transfer might be a sloppy transfer done ust to get a title out the door,much like many early DVD transfers when studios were just dumping whatever master they had onto a disc, rather than do a new one.

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.

It's pretty obvious that DVD has shown studios that during the early days, they can dump any sort of crap out there they want and the rabid adopters will buy it.  5 years from now they'll go back and do the remaster when there is a larger market.  Not all studios are this way, but Fox is certainly one of the worse offenders.

Right.  Going back to the original poster's comment, Hi-Def video formats would be worth tracking in addition to aspect ratio.  The Hd resolution being analogous to SD enhancement.  They're not the same thing, but if you cared about the one in SD, you'll care about the other in HD.
