How to make iOS App Preview for 6.5"

The specs state that the resolution for the video should be 886x1920 (or 1920x886).


How do I create a video with this resoultion?

I have looked at QuickTime Player, iMovie, and FinalCutPro and I don't see a way to produce a video with this resolution.


BTW: I don't have an iPhoneX of any kind. Does this fact alone mean I cannot produce a 6.5 inch App Preview?

It doesn't seem like it should but maybe..??


I hope I am just missing something easy but in the programs mentioned above I find only 480p, 720p, 1080p, and 4K.


Any guidance (a link to a "how to" with tools required?) would be really appreciated!

Use iMovie - File - New App Preview, then share it with App Preview
