It is usually described with two numbers and a colon between them — for example, 2:1. This means that the width of the image is twice its height. It's a very useful concept for resizing photos or videos for your blog or social media account. Asa result, the format standardised for anamorphic cinema production in the late 1950s is essentially the same one we'd used today if we shot anamorphic 35mm, using 2:1 compression to create a 2.35:1 frame. Later this increased very marginally to 2.39, mainly to better hide splices; again, it's just a crop, and the compression ratio of the 169 (or 1.78:1) If you’re ever in doubt, 16:9 (or 1.78:1) is the most common aspect ratio today — and there’s a few reasons why. This widescreen aspect ratio is 1) compatible with most standard HD televisions and computer monitors and 2) can host videos that have a different aspect ratio without distorting the image. 1.85:1 InComparison: 24 inch 16x10: 24 inch 16x9: Actual Aspect Ratios: 0.00% larger diagonal 5.18% larger area: 0.00% larger diagonal 4.93% smaller area: As a 4:3 Display Ihave a love/hate relationship with Christopher Nolan so I built a 1.90:1 ratio screen to enjoy 2.35:1, 16:9 and IMAX ratios. I have an Epson 4040. I previously had a 2.35:1 which was great, however I always needed to reduce image size for non widescreen. For a movie like Dunkirk, a 2.35:1 just won't do. Iam super confused with this 2.35:1 vs 16:9 stuff. 2.35:1 vs 16:9 means for the same height, a 2.35:1 movie will be wider than the 16:9 - but they will be the same height. So if that's the case, why is it that when I play a 2.35:1 movie on my 16:9 screen, I have black bars above/below the picture? 2.35:1 is supposed to be the same height, just Incomparison to a 15.6 inch 16x9 TV a 16.1 inch 16x9 is 3% larger diagonally and 7% larger by area as a 16x9 display. 3% larger diagonally and 7% larger by area as a 4x3 display. 185:1 and 2.35:1 are two of the most usual ARs used in movies (usually chosen for how well it fits the overall aesthetic of a given film). :1 was pretty much chosen to be a compromise of the two most common extremes, 4:3 (1.33:1) and 2.35:1.
