| | Posted: | | | | Is there a way to determine the widescreen ratio if it is not stated on the case.
Arrival/Arrival II box set...two movies on one DVD is where this question comes from.
The downloaded data with UPC for the case states 2.35:1
Using Disc ID for side A "The Arrival" lists 1.85:1 (The case just says 'Widescreen')
Using Disc ID for side B "Arrival II" lists the same 1.85:1 (The case says '4:3 Widescreen')
Wouldn't one of these have to be incorrect? The Box set info says 2.35:1 but both sides are listed as 1.85:1?

| | Posted: | | | | you don't need that. I use Nero Showtime, and use show all info. There you will see the screen ratio. |

| | Posted: | | | | The best way (and the way I do it for ALL profiles) is to use VLC Player (freeware) and Adobe Photoshop. If you don't have Photoshop you can get a free type of image editing software like Gimp or Irfanview32.
Start up VLC Player, and make sure the zoom is set to 1:1. Play the DVD. It should automatically switch to 4:3 or 16:9 mode, whichever is correct for the DVD. Freeze frame on a shot where all four screen boarders are brightly lit.
Hit "alt" + "printscreen" to take a screenshot.
(If you find that it doesn't work after you paste it, you may have to (in WinXP) right click your desktop, click "properties," click "settings" tab, click "advanced" button, click the "troubleshoot" tab, then move the "hardware accelleration" slider down to one notch over from the left.)
Open Photoshop, hit "file," "new," and it should automatically select the correct window size for the VLC Player window. Do an "edit," "paste" and a bitmap image of the VLC Player window will paste in.
Now zoom in so you can clearly see the edges of the screen, and use the "crop" tool to crop the image to include only the DVD image.
Do an "image," "properties," and it will give you pixels wide x pixels tall. This is the actual image size of movie on the DVD. Simply divide length x width and you'll get the aspect ratio. For example, if your image is 708 pixels wide by 408 pixels tall, then 708 / 408 = 1.735:1, or 1.74:1. That's what you should enter for the aspect ratio.
Very often the DVD case spec is wrong by some degree. It will say for example 1.78:1, when it's actually 1.75:1, and so on. And of course often times the case spec is spot on. Personally, I check using VLC / Photoshop for every audit I do. | | | | 99.9% of all cat plans consist only of "Step 1." |

Can I ask - how does Showtime work out the ratio? It's the same as what Grendell describes. But all you have to do, is to fire up the DVD in Nero Showtime and right-click. You will then find a option that says view -> Show additional info on OSD(Have installed and checked.) Then the information will show up as text on the screen. There you have audio and it shows the pixels. Just use the formula Grendell provided, and you get the aspect ratio. It's really simple. | | | | Last edited: by pompel9 |
