Make vertical Shorts that hold attention
Shorts, Reels and TikTok reward videos that are vertical, quick to the point and readable without sound. This generator starts from the same topic, script or audio input as a full video, but plans for a 9:16 frame and a short running time, with captions large enough to read on a phone.
If you already have a long widescreen video, you do not have to start again: reframe it to vertical with the subject kept in frame, or shorten it to a target length, then publish it to YouTube, TikTok or Instagram from the same library.
