I'd like this too. This is valuable information for every DVD collector and would be better if shared through the onlne database. (Yes, I know that documentation could be difficult...)

I am with, Jon. It sounds interesting but....a nightmare.

How exactly do you provide a source for whether something is OAR or not when contributing?

Okay, so what's the IAR of Once Upon a Time in Mexico, the theatrical of 2.40:1 or the one on all DVDs of 1.78:1?
What's the IAR of Panet Terror? Of Evil Dead? Apocalypse Now? RoboCop?

As i was writing this i did think that i can do this with tags but figured i'd post it anyway to see if maybe if enough people want\would use it that it could be added in as a feature.

I think you were right to post it anyway. Nearly all the data in DVDP could be stored as Tags or Notes, yet we do use other, more specific, fields 

OAR is generally considered to mean the theatrical aspect ratio, but even that can vary from theater to theater and print to print for a number of reasons.

However, an open matte presentation is not an OAR if it was originally projected with the mattes..

I am cinema club projectionist, and I kwon some about these things.

To theather to theather change minimun, if they have necesary optics. Coul be not not exactly, but very near will be.

To copy to copy, is very strange. The only case that i know, in firts scope films, it be a scope copies and not anamorfic scopes with aspect ratio respeted. The was prepared to with speferic optic show scope aspec ratio, logically, with not the same cauality.

The other reason, coud be with 35mm copys of 70mm copys.




About oppen mate. NEVER is format of the film. I know one film that was in 1:66 for cropping in projection or all micros are see. Intented ratio is the usual film projection format.

I allwais think in original aspect ratio. If director changed the format, is a new intented ratio, but not original.




that he was surprised when he was asked by the DVD company about aspect ratio, because he'd had no idea that most projectionists had been cropping his 1.33 image to 1.85!

And surprise? I am surprise that he don't know that in cinemas for cost they only have most used formats, specially un milticinemas. Usually only flat/panoramic (1:85) and scope (2:35). Only old cinemas and cultural cinemas like festivals have others formats.

If he would like evited cropping in cinemas, it must prepared for exhibition with 1:85 optics, that have blank lateral to show in cinemas like when you in 16/9 TV see 1:33 films. It wacht "Dancing in the rain" with copy do these, projection with 1:85 optic for waching in 1:33.

That's pretty much what I was referring to.

But think in that case, the original transfer is that original aspect ratio. Is very clear these point and must no be a problem.

See that The Dirty Dozen last edition has the original aspect ratio (It is vistavisión film) and the fisrt edition has incorrect aspect ratio. The last editions are made using restauration of original negatives, and the old edition is made using a 35mm copy that not respect original aspect ratio.
