I don't want to spoil the party but screen caps are only as good as the user/person who took them. That leaves room for errors/problems in my opinion. If you take them from the web somewhere they could be modified without your knowledge. I still believe that you should have the DVD when checking this.

I agree. Unless you captured the image yourself, you can't be sure that it is a true screen cap. Exactly, unless the DVD software was set to use the original aspect ratio then you could end up with practically anything. That said, I would believe MOST users who measured this way. What I wont believe is just based on watching the DVD on a normal TV. |

Ehh. No. It means that it's encoded in a ratio with none square pixels, allowing a widescreen TV to stretch the picture without loosing vertical resolution. There can certainly still be black bars on an anamorphic movies.

Darklynoon is correct...you will notice he said no black bars on the left and right, not top and bottom. He is talking about pillarboxing, not letterboxing. Non-anamorphic DVDs were designed for viewing on a standard 4:3 TV. When viewed on a 16:9 TV, they are stretched horizontally, but not vertically, so they appear "squished". To view a non-anamorphic DVD, on a 16:9 tv, without distorting the picture, you have to pillarbox it. Anamorphic widescreen solves this problem. Simply put, it is encoded in such a way that it can be streched properly, eliminating the distortion. | | | No dictator, no invader can hold an imprisoned population by force of arms forever.

That is exactly what I meant Unicus, tho there is one exception, an enhanced 1:1.66 movie will still have some black bars on left and right. This is what i forgot to mention. cheers Donnie | | | | www.tvmaze.com |

| | Posted: | | | | But it doesn't say that all these movies have a ratio of 1.85:1. The ratio varies, the process is the same but not the ratio. We are going in circles here.

It still surprises me to learn how many people still don't understand a feature that's been around since 1997, ie. the dawn of DVD.

| | Posted: | | | | Let me try this one more time for those that still don't get it. The term 'anamorphic' has nothing to do with aspect ratio but has everything to do with how the image is displayed. Let's look at some examples to see if it helps get that point across. First, 1.85:1...  This is a non-anamorpic image as displayed on a 16:9 TV. Notice how the image looks "squished"? That is because it was designed to be viewed, in a letterbox format, on a 4:3 TV. When viewed on a 16:9 TV, it is horizontally stretched to fit the screen. The source is still 1.85:1, but the TV has distorted the image so that it fits into the widescreen.  This is the same image, anamorphically enhanced for widescreen TVs. Again, the source is 1.85:1, but it has been encoded in such a way that it is displayed properly on a 16:9 TV. When displayed on a 4:3 TV, it will automatically be letterboxed. Now, 2.35:1...  This is a non-anamorphic image as displayed on a 16:9 TV. As with the image above, and for the same reason, it is "squished".  This is the same image, anamorphically enhanced for widescreen TVs. Notice the black bars at the top and bottom? These are there because the source is 2.35:1. The fact that it is "anamorphically enhanced for widescreen TVs" does not change the aspect ratio, it simply allows it to be displayed properly. | | | No dictator, no invader can hold an imprisoned population by force of arms forever.

Look at the Mess that HDA&E sometimes show on their network with certain widescreen titles.. They are short -fat and uncomfortable looking.. Now that we have gone 'all digital' here in the states, we are getting this a lot. The problem is the same as it is with a nonanamorphic DVD. The broadcasters are transmitting the same exact source they always did, designed for a 4:3 television, and it is being streched to fit a 16:9. If I set my TV to pillarbox the image, it looks fine. If I don't, it looks distorted. Fortunately, some of our stations are broadcasting a pillarboxed image for non-widescreen shows, but they all aren't...which just drives me nuts.  | | | No dictator, no invader can hold an imprisoned population by force of arms forever.

Skip You are correct, this is why it is important to actually measure the image as not everybody will see those tiny black bars...good eyes.  | | | No dictator, no invader can hold an imprisoned population by force of arms forever.
