As shown in class, HandBrake is to go-to tool from cropping/changing aspect ratio of video.
But VLC is the tool to use for quickly trying out different crops in real time. It’s now in our Tools > Software page. It’s the best and most powerful video player for Macs, Windows, and Linux. And it’s very good for testing out cropping options for different aspect ratios: Video > Crop > or press “C” over and over to rotate through all choices – 16:9, 4:3, 1:1, 16:10 (MacBook screen), 2.21:1, 2.35:1, 2.39:1, 5:4.
