ScreenFlow terms

Pixel Aspect Ratio

The ratio of width to height of a single pixel in a video frame.

What is the pixel aspect ratio in ScreenFlow?

ScreenFlow is a popular video editing and screen recording software for Mac. However, it does not specifically define a "pixel aspect ratio" within its settings or features. The term "pixel aspect ratio" refers to the ratio of the width to the height of a single pixel in a digital image.

In most modern systems, including ScreenFlow, this ratio is 1:1, meaning the pixel is as wide as it is tall, resulting in a square pixel. The resolution or aspect ratio of the overall video or image can be adjusted in ScreenFlow, but this does not change the pixel aspect ratio. The software automatically handles the pixel aspect ratio based on the source material and the output settings chosen by the user.

How to adjust the pixel aspect ratio in ScreenFlow?

To adjust the pixel aspect ratio in ScreenFlow, you first need to open the software and select the project you want to edit. Once you have your project open, navigate to the top menu and click on "File". In the drop-down menu, select "Document Settings".

In the Document Settings window, you will find the option to adjust the pixel aspect ratio. Click on the drop-down menu next to "Pixel Aspect Ratio" and select the ratio that you want. After you have made your selection, click "OK" to save your changes. Please note that changing the pixel aspect ratio can affect the quality of your video, so it's recommended to use the default setting unless necessary.

Why is pixel aspect ratio important in ScreenFlow?

Pixel aspect ratio is crucial in ScreenFlow because it directly impacts the quality of the video output. ScreenFlow is a screen recording and video editing software, and the pixel aspect ratio determines how the pixels are displayed on various screens. If the aspect ratio is not correct, the video may appear distorted or stretched, negatively affecting the viewer's experience.

Moreover, different devices and platforms may have different preferred pixel aspect ratios. Therefore, when creating content in ScreenFlow, it's important to consider the pixel aspect ratio to ensure the video will display correctly across different devices. This is particularly important for professionals who want their content to look its best regardless of where or how it's being viewed.

Can I change the pixel aspect ratio in ScreenFlow after recording?

No, you cannot directly change the pixel aspect ratio in ScreenFlow after recording. ScreenFlow does not provide an option to alter the pixel aspect ratio of a recorded video directly within the software. The pixel aspect ratio is determined by the resolution at which you recorded your screen or video, and it remains fixed once the recording is done.

However, you can indirectly change the aspect ratio by cropping or resizing the video in the editing process. This can be done by selecting the video clip in your timeline, then adjusting the video properties in the video tab. Keep in mind that this may affect the quality of your video, as you are essentially removing parts of the video or stretching it to fit a different aspect ratio. It's always best to plan your desired aspect ratio before you start recording.
