Disclaimer: I’m not a video expert, so this tutorial may be entirely wrong. It reflects only my understanding of what I’ve learned so far about editing video files.
Note: I had intended to write a series of tutorials while I dealt with some menial task for a video project, but those tasks turned out to be easier than expected. So I’m not sure how many more of these entries I’ll write.
Assuming you can get through all the jargon that gets thrown around.
Here’s the thing you should come away with in learning about video resolution: there are many ways to describe the same thing.
Let’s begin with aspect ratio, the width of an image divided by its height. Long ago and far away when televisions started inching their way into American homes, film studios combated the perceived threat of the medium by expanding the size of the theater screen. As a result, films have an aspect ratio of 16:9, while TV has an aspect ratio of 4:3. That’s the simple history of aspect ratios.
Now comes the hard part.
