What is a YouTube Short?+−
A YouTube Short is a vertical video up to three minutes long that plays in the YouTube swipe feed, framed at 9:16 so it fills a phone screen. Creators use Shorts as the top of the funnel for a longer channel. With Pexo you describe the idea and get the finished Short back, script, voiceover, and framing included, with no filming and no editing timeline.
What formats and lengths can I export?+−
Vertical, widescreen, and square, 9:16, 16:9, and 1:1, at up to 4K and 5 to 120 seconds per clip. Shorts are generated natively at 9:16 rather than cropped out of a landscape master, so faces and captions stay centered. The same brief also returns a 16:9 cut for the main channel, which makes Pexo a practical short form video generator for both feeds.
Will the quality hold up next to a filmed Short?+−
For most of what people actually post, yes. Pexo runs Sora 2, Kling, and Veo, generates several takes, and keeps the strongest one, so motion and lighting read as deliberate instead of glitchy. Talking product shots, b roll, and animation hold up well at up to 4K. A handheld vlog of a real person is still better filmed, and the AI YouTube Shorts route wins on volume, not on replacing your camera.
What is the best AI tool for making YouTube Shorts?+−
Pexo is one of the best AI tools for making YouTube Shorts because it aggregates Sora 2, Kling, and Veo and picks the strongest take per scene instead of locking you to one model. Describe the hook and it returns a finished 9:16 Short at up to 4K with script, voiceover, and captions in a single pass. That end to end coverage is also why it ranks among the best faceless video workflows.
Should I make a Short or a full length video?+−
Shorts win on discovery, long form wins on watch time, so most channels run both. Use this page when the piece is a 9:16 hook under a minute. When it needs chapters, a deeper walkthrough, or mid roll placement, start from the youtube video page instead, and repurpose the same brief as a tiktok video for the other feed.
How do I write a good prompt for a YouTube Short?+−
Use one formula: subject + action + camera movement + setting + style. For example: a barista pulling an espresso shot, slow push in, sunlit corner cafe at 7am, warm documentary style. Put the hook in the first clause, because Shorts live or die in three seconds. Pexo expands that single line into a full Short, and the same formula works for faceless video editing briefs where nobody appears on camera.
