Three Ways to Resize Video on Mac (macOS Sierra Included)

Method 1: Change Video Format to Resize Video

Videos that encoded with different formats will have different size. Usually, if you rip DVD to a digital file, the size will be smaller to rip DVD to H.264/H.265 MP4 and WMV than converting DVD to MPG, AVI. Below is a test. I ripped a DVD to different formats in HD resolution and then sizes were different.

In addition, for those video editors that come with video resizing feature, it is always embedded deep in the settings and is not available in the frontend. In this tutorial, let’s see how you can resize your video in various OS. Note: The meaning of “resize” in this article is referring to the display size of the video, not the file size.
