What is a short-form vertical video?
Short answer
A short-form vertical video is a video in a 9:16 portrait frame, usually under a minute or two, made for phone feeds like Instagram Reels and YouTube Shorts.
The vertical frame fills a phone screen, which is why it dominates mobile feeds. Short length means the video has to make its point quickly.
Short vertical videos are recommended to people beyond the account’s followers, based on how well they hold attention. That is what lets small accounts reach large audiences.
Pomera campaigns are built entirely on this format. See what Instagram Reels are and what YouTube Shorts are.
