Working with video footage can be a daunting task, especially when it comes to maintaining the correct pixel aspect ratio. Adobe Premiere Pro is a powerful video editing software that can help you achieve professional-looking results, but even experienced editors may encounter issues with pixel aspect ratio. In this article, we’ll delve into the world of pixel aspect ratio, exploring what it is, why it’s important, and most importantly, how to fix it in Premiere Pro.
What is Pixel Aspect Ratio?
Before we dive into fixing the pixel aspect ratio in Premiere Pro, let’s take a step back and understand what it is. Pixel aspect ratio refers to the ratio of a pixel’s width to its height. In other words, it’s the proportional relationship between the horizontal and vertical dimensions of a single pixel. This ratio can vary depending on the type of video footage, camera, and editing software used.
In the early days of video production, cameras and editing systems used a 4:3 aspect ratio, which meant that the horizontal resolution was 4 units and the vertical resolution was 3 units. However, with the advent of widescreen TVs and high-definition (HD) video, the aspect ratio shifted to 16:9, which is the standard for most modern video content.
Why is Pixel Aspect Ratio Important?
Maintaining the correct pixel aspect ratio is crucial for several reasons:
- Preserves the original frame’s aspect ratio: A correct pixel aspect ratio ensures that the video is displayed in its original format, without any distortion or stretching.
- Maintains video quality: A mismatched pixel aspect ratio can lead to a loss of video quality, resulting in a soft or blurry image.
- Ensures compatibility: A correct pixel aspect ratio ensures that your video is compatible with various devices and platforms, including TVs, computers, and mobile devices.
Causes of Pixel Aspect Ratio Issues in Premiere Pro
Now that we’ve established the importance of pixel aspect ratio, let’s explore the common causes of pixel aspect ratio issues in Premiere Pro:

What is the Pixel Aspect Ratio and why is it important in video editing?
The Pixel Aspect Ratio (PAR) is the ratio of the number of pixels horizontally to the number of pixels vertically in a digital image. In video editing, PAR is crucial as it determines how the video is displayed on different devices and platforms. A wrong PAR can result in distorted or stretched footage, making it essential to set it correctly in Premiere Pro.
In Premiere Pro, the PAR is usually set automatically based on the footage’s native resolution and frame rate. However, sometimes the PAR might need to be adjusted manually to match the intended display device or platform. For instance, if you’re editing a project for a 4:3 TV broadcast, you’ll need to set the PAR to 0.9, whereas for a widescreen HD project, you’ll need to set it to 1.0. Understanding the importance of PAR and how to adjust it in Premiere Pro is vital for achieving professional-looking results.
What are the common Pixel Aspect Ratio values and when to use them?
The most common PAR values are 0.9, 1.0, and 1.333. A PAR of 0.9 is typically used for standard definition (SD) footage, especially for 4:3 TV broadcasts. A PAR of 1.0 is used for high definition (HD) footage, specifically for widescreen formats like 16:9. A PAR of 1.333 is used for anamorphic footage, which is often used in cinematic productions.
When choosing a PAR value, it’s essential to consider the type of footage you’re working with and the intended display device or platform. For example, if you’re working with SD footage originally shot in 4:3, you’ll need to set the PAR to 0.9 to ensure it’s displayed correctly. If you’re working with HD footage shot in 16:9, you’ll need to set the PAR to 1.0. Using the incorrect PAR value can result in distorted or stretched footage, so it’s crucial to get it right.
How do I identify if my footage has the wrong Pixel Aspect Ratio in Premiere Pro?
To identify if your footage has the wrong PAR in Premiere Pro, look for visual signs of distortion, such as stretched or squished images. You can also check the footage’s properties by right-clicking on the clip in the Project panel and selecting “Media” and then “Get Properties.” This will display the footage’s resolution, frame rate, and PAR.
If you’re still unsure, you can also use Premiere Pro’s “Display Aspect Ratio” feature to visually check the PAR. To do this, go to the “Sequence” menu, select “Settings,” and then click on the “Display Aspect Ratio” dropdown menu. Here, you can select different PAR values to see how they affect the footage. If the footage looks distorted or stretched, it’s likely that the PAR is set incorrectly.
How do I fix the Pixel Aspect Ratio in Premiere Pro?
To fix the PAR in Premiere Pro, you’ll need to adjust the “Pixel Aspect Ratio” setting in the “Sequence Settings.” To do this, go to the “Sequence” menu, select “Settings,” and then click on the “Pixel Aspect Ratio” dropdown menu. Here, you can select from a range of PAR values or enter a custom value.
Once you’ve set the correct PAR, you may need to adjust the footage’s scale and position to ensure it fits the frame correctly. You can do this by using the “Scale” and “Position” tools in the “Effect Controls” panel. Additionally, you may need to adjust the sequence’s resolution and frame rate to match the corrected PAR.

Failing to fix the PAR in Premiere Pro can result in distorted or stretched footage, which can be noticeable in the final output. This can be particularly problematic if you’re delivering the project to a client or broadcasting it on TV. A wrong PAR can also make it difficult to achieve accurate color grading and visual effects, as the footage may not be displayed correctly.
In addition, not fixing the PAR can also lead to issues when exporting the project. For example, if you’re exporting the project in a different resolution or frame rate, a wrong PAR can result in further distortion or cropping. To avoid these issues, it’s essential to fix the PAR early on in the editing process to ensure that your project looks professional and polished.
Can I fix the Pixel Aspect Ratio in other video editing software?
Yes, most video editing software, including Final Cut Pro, Avid Media Composer, and DaVinci Resolve, allow you to adjust the PAR. The process may vary depending on the software, but the principle remains the same. In general, you’ll need to access the sequence or project settings and adjust the PAR value accordingly.
It’s worth noting that some software may not provide an explicit PAR setting, and instead, may use a different terminology or approach to achieve the same result. For example, some software may use a “display aspect ratio” or “frame aspect ratio” setting, which serves a similar purpose to the PAR. Consult the software’s documentation or online resources if you’re unsure how to adjust the PAR.
Are there any best practices for working with Pixel Aspect Ratio in Premiere Pro?
Yes, there are several best practices for working with PAR in Premiere Pro. First, it’s essential to set the correct PAR early on in the editing process to avoid potential issues later on. Second, always check the footage’s properties and PAR value before starting to edit. Third, use the “Display Aspect Ratio” feature to visually check the PAR and ensure it’s set correctly.
Additionally, it’s a good idea to create a new sequence setting specifically for each project, rather than using a generic preset. This allows you to customize the PAR, resolution, and frame rate to match the project’s specific requirements. Finally, always double-check the PAR value before exporting the project to ensure that it’s set correctly for the intended delivery platform or device.
