How to Change Video Aspect Ratio in Adobe Premiere

At the very top is a drop down menu called Editing Mode.

You can choose from one of the presets the Adobe has kindly included, or you can enter the new settings in the Video section below the drop down, if you don’t find one that suits you.

There are actually 2 ways to do this in Premiere Pro. The first is under sequence settings where instead of the default 1920×1080 (16:9) settings, you can adjust the screen height to 1038(1.85:1) or 817 (2.35:1).

For 1080p footage shot anamorphically, you could adjust the width to 2538 for a better picture resolution in the 2.35 cinemascope aspect ratio.

The second is using the default 16:9 screen image, you could crop the video image to the desired ratio under Video Effects or use a 1.85:1 or 2.35:1 letterbox PNG overlay like I use for my videos.

These are fairly easy to create in Adobe Photoshop provided you set the background to ‘Transparent’.

Premiere Pro sequences have a resolution found in the Sequence menu – Sequence Settings.

Change the Editing Mode to Custom, and type in whatever resolution you wish. For example, 1920×858. The aspect ratio is displayed next to the raster size.

If you need to change the aspect ratio of a clip – for example, fix a distorted clip due to an anamorphic lens – right-click on the clip in the bin. Go to Modify-Interpret Footage. Change the Pixel Aspect Ratio.
