If you’re looking to change the aspect ratio on HandBrake, there are a few different ways to go about it. The first option is to open the HandBrake preferences and change the “Aspect Ratio” setting. This will allow you to select between a variety of different aspect ratios, including 4:3, 16:9, and 1:1. If you’d rather not deal with the preferences menu, you can also use the HandBrake shortcut keys (cmd+shift+A/D) to change the aspect ratio on-the-fly. Simply press cmd+shift+A/D to select “Aspect Ratio” from the shortcut menu, and then enter your desired ratio into the input box. whichever option you choose, be sure to test it out before finalizing your changes – once you’ve made them live, they may not look as intended! ..
