An attribute ratio specifies the ratio of width to acme. Video and even so picture frames have a frame aspect ratio. The pixels that make up the frame have a pixel aspect ratio (sometimes referred to as PAR). Different video recording standards use dissimilar aspect ratios. For instance, you record video for television receiver in either a four:3 or xvi:nine frame aspect ratio. For more than data, see Frame aspect ratio.

When a project is created in Premiere Pro, you set the frame and pixel aspect. One time these ratios are set, you cannot alter them for that projection. However, you can modify the attribute ratio of a sequence. You lot can besides utilise assets created with different aspect ratios in the project.

Premiere Pro automatically tries to compensate for the pixel aspect ratio of source files. If an nugget still appears distorted, you tin can manually specify its pixel attribute ratio. Reconcile pixel aspect ratios before reconciling frame aspect ratios, because an wrong frame aspect ratio tin can event from a misinterpreted pixel aspect ratio.

Types of aspect ratios

Unremarkably used attribute ratios are:

Widescreen (16:9)

It is the standard aspect ratio unremarkably shared by online videos, documentaries, and films. It captures a large amount of data with details.

Vertical (ix:16)

Information technology is the video recorded on your phone.

Fullscreen (4:three)

It is the aspect ratio that was used on television set earlier widescreen was used. Information technology focused on a particular element at a fourth dimension.

Square (i:one)

It is a perfect square ratio that is ordinarily used on Instagram.

Anamorphic (two.40:ane)

It is a wide widescreen often used in movies. Information technology is like to 16:9 but the height and bottom are cropped. This effect gives information technology a cinematic feel.

Anamorphic (2.40:1) — Anamorphic (2.40:ane)

Fix the aspect ratio

To prepare the aspect ratio of a sequence:

Get to the Settings tab of the New Sequence dialog box.

Nether Video, enter the Frame Size(height) and horizontal(width). Premiere Pro automatically generates the aspect ratio.

Fill out the respective fields, name the sequence, and click OK.

The aspect ratio for the sequence has been prepare.

Frame aspect ratio

Frame aspect ratio describes the ratio of width to height in the dimensions of an paradigm. Video and still picture frames have a frame attribute ratio.

For example, DV NTSC has a frame aspect ratio of 4:3 (or 4.0 width past three.0 pinnacle). A typical widescreen frame has a frame attribute ratio of 16:9. Many cameras that have a widescreen mode tin record using the 16:9 aspect ratio. Many films have been shot using even wider attribute ratios.

In Premiere Pro, y'all can implement the letterboxing or the pan and scan technique by using Motion effect properties such as Position and Scale.

Letterboxing

When you import clips shot in one frame aspect ratio into a project that uses some other frame aspect ratio, y'all decide how to reconcile the different values. This placement leaves blackness bands above and below the moving-picture show frame, chosen letterboxing.

For example, two common techniques are used for showing a sixteen:ix motion picture on a 4:3 standard idiot box. You tin can fit the entire width of the 16:ix moving-picture show frame within the 4:3 idiot box frame.

Pan and scan

Pan and scan is an alternative method to use a project with another frame aspect ratio. Merely a part of the frame is retained, while the rest is lost.

For example, another technique to show a 16:9 film on a 4:iii standard television is to fill the 4:3 frame vertically with the unabridged height of the 16:9 frame. And so, yous pan the horizontal position of the sixteen:9 frame inside the narrower 4:3 frame so that important activeness e'er remains inside the 4:3 frame.

Pixel aspect ratio

Pixel aspect ratio describes the ratio of width to elevation of a single pixel in a frame. The pixels that brand upward a frame take a pixel aspect ratio (sometimes referred to every bit PAR). Pixel attribute ratios vary considering different video systems make various assumptions almost the number of pixels that are required to fill a frame.

For example, many computer video standards ascertain a iv:iii attribute ratio frame every bit 640x480 pixels loftier, which results in square pixels. The computer video pixels take a pixel aspect ratio of one:ane (square). Video standards such as DV NTSC ascertain a 4:3 aspect ratio frame as 720x480 pixels, which result in narrower, rectangular pixels. The DV NTSC pixels have a pixel attribute ratio of 0.91 (nonsquare). DV pixels, which are always rectangular, are vertically oriented in systems producing NTSC video and horizontally oriented in systems producing PAL video. Premiere Pro displays clip pixel aspect ratio next to the clip epitome thumbnail in the Project panel.

A. 4:3 square-pixel prototype displayed on four:3 square-pixel (estimator) monitorB. 4:3 foursquare-pixel image interpreted correctly for display on 4:iii non-square pixel (TV) monitorC. 4:3 square-pixel image interpreted incorrectly for display on iv:3 non-square pixel (TV) monitor

The clean aperture is the portion of the image that is free from artifacts and distortions that appear at the edges of an image. The production aperture is the unabridged paradigm.

Distorted images

If you display rectangular pixels on a foursquare-pixel monitor without alteration, images appear distorted. For example, circles misconstrue into ovals. Yet, when displayed on a broadcast monitor, the images announced correctly proportioned because broadcast monitors utilize rectangular pixels. Premiere Pro tin display and output clips of various pixel aspect ratios without baloney. Premiere Pro attempts to automatically reconcile them with the pixel aspect ratio of your project.

You could occasionally meet a distorted clip if Premiere Pro interprets pixel attribute ratio incorrectly. You can right the distortion of an individual prune by manually specifying the source prune pixel attribute ratio in the Translate Footage dialog box.

Apply assets with various aspect ratios

When an asset is imported, Premiere Pro attempts to preserve the frame attribute ratio, pixel aspect ratio, and frame dimensions so the asset does non appear cropped or distorted.

For avails that comprise metadata, these calculations are automatic and precise. For example:

When you capture or import NTSC footage with the ATSC frame size of 704x480, the D1 frame size of 720x486, or the DV frame size of 720x480, the pixel attribute ratio is ready to D1/DV NTSC (0.91).
When y'all capture or import footage with the HD frame size of 1440x1080, the pixel aspect ratio is set to Hard disk drive 1080 Anamorphic (1.33).
When you capture or import PAL footage with the D1 or DV resolution of 720x576, the pixel aspect ratio is set to D1/DV PAL (1.094).

For other frame sizes, Premiere Pro assumes that the asset was designed with square pixels and changes the pixel aspect ratio and frame dimensions to preserve the image aspect ratio. If the imported asset is distorted, you tin modify the pixel attribute ratio manually.

Avails in a sequence

When you drag an nugget into a sequence, the asset is placed at the eye of the program frame by default. Depending on its frame size, the resulting image could be also small or over cropped for the needs of the projection. Premiere Pro can alter its scale automatically when you drag an nugget into a sequence, or you can change it manually.

It is always important to interpreted files correctly. You tin can read nugget frame dimensions and pixel aspect ratio near the preview thumbnail and in the Video Info cavalcade of the Project console. You lot can likewise find this data in the asset Properties dialog box, the Interpret Footage dialog box, and the Info panel.

Aspect ratio distortion in sequences

The sequence settings preset you choose when y'all create a sequence sets the frame and pixel aspect ratios for the sequence. You can't alter aspect ratios after you create the sequence, but you can change the pixel attribute ratio that Premiere Pro assumes for private avails.

For example, if a square-pixel asset generated by a graphic looks distorted in Premiere Pro, you can right its pixel aspect ratio to make information technology wait right. Past ensuring that all files are interpreted correctly, you tin can combine footage with different ratios in the same project. And so y'all can generate output that doesn't misconstrue the resulting images.

Right aspect ratio misinterpretations

Right individual attribute ratio misinterpretations

To correct private aspect ratio interpretation, do the following:

Right-click the notwithstanding prototype in the Projection panel.

Select Prune >Modify > Translate Footage .

If you select a prune on the Timeline panel or Program monitor, the choice is unavailable.

Select 1 of the following in the Pixel Aspect Ratio department:

Use Pixel Aspect Ratio From File

Uses the original aspect ratio saved with the notwithstanding image.

Conform To

Lets you choose from a list of standard aspect ratios.

When using Photoshop to generate images for utilise in video projects, it's best to use the Photoshop preset named for the video format you'll utilise. Using the preset ensures that your images are generated with the correct aspect ratio.

Common pixel aspect ratios

	Pixel aspect ratio	When to use
Foursquare pixels	1.0	Footage has a 640x480 or 648x486 frame size, is 1920x1080 HD (not HDV or DVCPRO HD), is 1280x720 Hard disk drive or HDV, or was exported from an application that doesn't support nonsquare pixels. This setting tin can also be appropriate for footage that was transferred from film or for customized projects.
D1/DV NTSC	0.91	Footage has a 720x486 or 720x480 frame size, and the desired event is a four:3 frame aspect ratio. This setting tin also be advisable for footage that was exported from an application that works with nonsquare pixels, such as a 3D animation application.
D1/DV NTSC Widescreen	1.21	Footage has a 720x486 or 720x480 frame size, and the desired result is a 16:ix frame attribute ratio.
D1/DV PAL	1.09	Footage has a 720x576 frame size, and the desired effect is a 4:3 frame attribute ratio.
D1/DV PAL Widescreen	1.46	Footage has a 720x576 frame size, and the desired result is a sixteen:9 frame aspect ratio.
Anamorphic 2:one	2.0	Footage was shot using an anamorphic film lens, or it was anamorphically transferred from a film frame with a 2:ane aspect ratio.
HDV 1080/DVCPRO HD 720, Hard disk drive Anamorphic 1080	1.33	Footage has a 1440x1080 or 960x720 frame size, and the desired effect is a 16:ix frame aspect ratio.
DVCPRO HD 1080	1.5	Footage has a 1280x1080 frame size, and the desired effect is a 16:9 frame aspect ratio.
