4k Cinematic for YouTube

Absolutely! I’m eager to see what you create. And I forgot to mention something else…

The phrase “21:9 ultra-wide” is an incredibly generic marketing term that is applied to a lot of resolutions that are not true 21:9 in the mathematical sense. Like my first post showed, 3840x1600 is 2.4 whereas 21:9 is 2.333, and pixels will have to be squished non-square to correctly make up the difference. (That’s a bad thing.)

There is a chart on Wikipedia of common “21:9” monitor resolutions and their true aspect ratios:

  • 3840x1600 is actually 12:5
  • 2560x1080 is actually 64:27

Remember to use these values instead of 21:9 when setting up your custom video mode and when doing your export.
