There are two contributions up for voting right now to change Gone With the Wind and The Wizard of Oz from A/R 1.33:1 to 1.37:1.

The fact is that all movies prior to cinemascope (and after 1932), except silent films, were filmed on 35mm film in aspect ratio 1.375:1!

We have used 1.33:1 for these films for as long as DVDP has been around.  Are we really going to go back and change all of these profiles?  If the answer is yes, then we need to change it to 1.375:1, not 1.37:1!

See this site for more details:

If it is really 1:375 Then I would say round to 2 decimals and call it 1.38 actually

To be absolutely precise, the actual frame size is .866" X .630", generating an aspect ratio of 1.3746031746:1!

Perhaps that's what we should be entering into DVDP!

Interestingly enough, if you change the A/R to 1.37:1, but use icons instead of text for the video formats section within DVDP, the program still displays 1.33:1.

lol, No need to be that precise.

It seems that 2 decimals seems to be what DVDp uses for precession so that is what I would round it to based on the actual data.

While not manifested in the rules, I remember in the discussion it was mostly agreed that 0.4 would be enough of a difference to warrant a change. The rules do ask that the verification method is to be stated in the contribution notes. After all, it is not about what the film was filmed on, but what it was transfered in on DVD/Blu-ray.


If it is indeed 1.3746031746:1, then 1.375 is just as correct as 1.37.


I will voted for change, but not "all", only those where aplpicable.

We generally use the aspect ratio of the movie on DVD, not the one in theaters. Many encoded movies are cropped to fit a 4/3 screen (1.33) or a 16/9 screen (1.78), even if the original ratio was 1.37 or 1.85.

If the decoded image fits exactly a 4/3 screen, we should use 1.33. If we see black bars on top or bottom on a 4/3 image, then it is 1.37. The difference is harder to see on a 16/9 encoding (specially blu-rays since anamorphic DVDs are rare for 1.33 movies) where left and right bars are quite the same between 1.33 and 1.37. This case needs a screen capture and a precise measure to be sure.

Thanks Achim.
This mirrors my thoughts quite well.
It all seems so stupid, it makes me want to give up!
But why should I give up, when it all seems so stupid?

Agreed. We should use the AR from the DVD. The original AR is not relevant.

The aspect ratio is the aspect ratio. But this is DVD Profiler, where instead of using the actual aspect ratio, we use... well I don't know what we use, but it's often not the actual aspect ratio. I guess, for example, a 1.76 film is supposed to be in the online as 1.78. I have no idea why, but if you try to change it to 1.76 and post documented proof, it will still get downvoted. I guess because this is DVD Profiler and that's just what we do.

Remember that we do not use the original aspect ratio. Instead we use the aspect ratio used on DVD. Therefore whenever you want to enter 1.37:1 you should see some small black bars in the window when you use a player software (e.g. PowerDVD). If the image is a little bit cropped on your DVD and completely fills your 1.33:1 window, you have to enter 1.33:1 whatever the OAR has been on film. In my experience this is most often the case with older film.

Most Blu-rays of academy-ratio films are 1.37. DVDs tend to be 1.33. there's little point in putting a row of 7 black pixels each at the top and bottom of the frame. Window-boxed ones may be 1.37, though. I agree only how it's presented on the DVD itself should count. Also, what 1.76 releases even exist? If it fills a 16:9 frame, it's 1.777777... or rounds off to 1.78.

This    how it is presented on DVD or Blu-ray which ever is being profiled.

An even bigger problem if you get right to the nuts and bolts of this IS: ..

I own both GWTW and Wizard of OZ editions  and yet I don't see either of these in ( my) data to be voted on .. Reason?  There is probably about two dozen releases of various regions and locality's as well as many versions in One disc two disc editions as well as STD  and Blu ray .. of said Titles .
One thing I can't stand to see is one (two) disc 'only versions'  being "accepted" for various changes of either (i.e.)  aspect ratio ( as here)  or crew and cast / running times as well as overviews and other ''trivia''  being changed for that one UPC edition(s)  ..  yet it doesn't branch out to affect all said Titles ..

So if aspect ratio gets changed (as you say)  will all movies of the same ratio get changed? 
Well that would be near Impossible to do,  let alone even all these said  various releases ... of said Titles ..
