Convert square video to rectangle1/13/2024 ![]() The "Academy ratio" of 1.375:1 was used for all cinema films in the sound era until 1953 (with the release of George Stevens' Shane in 1. In American cinemas, the common projection ratios are 1.85:1 and 2.39:1. This aspect ratio of 2.39:1 was confirmed by the most recent revision from August 1993 (SMPTE 195–1993). An update in 1970 (PH22.106-1971) changed the aspect ratio to 2.39:1 in order to make splices less noticeable. A SMPTE specification for anamorphic projection from 1957 (PH22.106-1957) finally standardized the aperture to 2.35:1. After 1952, a number of aspect ratios were experimented with for anamorphic productions, including 2.66:1 and 2.55:1. ![]() The motion picture industry convention assigns a value of 1.0 to the image's height an anamorphic frame (since 1970, approximately 2.4:1) is often incorrectly described (rounded) as 2.40:1 or 2.40 ("two-four-oh"). With a space designated for the standard optical soundtrack, and the frame size reduced to maintain an image that is wider than tall this resulted in the Academy aperture of 22 mm × 16 mm (0.866 in × 0.630 in) or 1.375:1 aspect ratio. The film itself is 35 mm wide (1.38 in), but the area between the perforations is 24.89 mm × 18.67 mm (0.980 in × 0.735 in), leaving the de facto ratio of 4:3, or 1. The universal standard (established by William Dickson and Thomas Edison in 1892) is a frame that is four perforations high. In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. With television, DVD and Blu-ray Disc, converting formats of unequal ratios is achieved by enlarging the original image to fill the receiving format's display area and cutting off any excess picture information ( zooming and cropping), by adding horizontal mattes ( letterboxing) or vertical mattes ( pillarboxing) to retain the original format's aspect ratio, by stretching (hence distorting) the image to fill the receiving format's ratio, or by scaling by different factors in both directions, possibly scaling by a different factor in the center and at the edges (as in Wide Zoom mode). Other aspect ratios, such as 5:3, 5:4, and 1:1 (square format), are used in photography as well, particularly in medium format and large format. In still camera photography, the most common aspect ratios are 4:3, 3:2 (1.5:1), and more recently found in consumer cameras, 16:9. ![]() Other cinematic and video aspect ratios exist, but are used infrequently. 7:1), universal for high-definition television and European digital television. 3:1), the universal video format of the 20th century, and 16:9 (1. Two common videographic aspect ratios are 4:3 (1. The common film aspect ratios used in cinemas are 1.85:1 and 2.4:1. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography. For the x: y aspect ratio, the image is x units wide and y units high. The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as 16:9, sixteen-to-nine. Watch the images get processed at light speed and available in a zip file for you to download in no time.Polyvision, consisting of three side-by-side frames of 4:3. Just drag and drop all your images or logos select your margin px and color then press submit. Go ahead and bulk process all those logos really quickly. That’s one of the many reasons we use square my image for. If this has ever sounded like you and half way through the process you thought “There has to be a better way”. You then power through the grueling editing process hoping not to get any rings, dings or pings. So your pour another cup of coffee and tell yourself that your going to get through all 100 logos before this cup is finished. Have you ever had several logos that were all different rectangle sizes and you wanted to make them uniform squares? Of course having all your logos on your website or graphic in perfect grid is exactly what you want but that would require opening Photoshop to edit each photo and either crop it or add space on the size to make every logo a perfect square.
