What size is 9:16?

1080 × 1920 pixels is the standard. For the height of any 9:16 frame multiply the width by 16 and divide by 9: 720 × 1280, 1440 × 2560 and 2160 × 3840 are also 9:16.

How do I set up a vertical timeline?

Premiere Pro: create a sequence with a custom frame size of 1080 × 1920, or run Sequence › Auto Reframe Sequence on a finished edit. Final Cut Pro: choose Vertical as the video format when you create the project. DaVinci Resolve: when you create the timeline, untick Use Project Settings and set the resolution to 1080 × 1920.

What happens to a 16:9 video in a 9:16 frame?

It either sits in the middle with large bars above and below, or it has to be cropped to a narrow vertical slice. Reframe it so the subject stays inside the new frame. Premiere Pro’s Auto Reframe, Final Cut Pro’s Smart Conform and DaVinci Resolve Studio’s Smart Reframe track the subject for you; otherwise scale the clip up and position it by hand.

Is 9:16 the same as 1080p?

1080p names the short side: a 1080 × 1920 vertical video has the same pixels as 1920 × 1080, turned upright. Platforms list it as 1080p.
