Your channel, vertical, without starting over.
Most long-form channels have no Shorts because vertical means redoing the storyboard, the framing, and the captions. In Framesail it's one toggle: the same style, cast, and narrator, composed for the tall frame from the first shot, ready for YouTube Shorts, Reels, and TikTok.
The same tool as our long-form video generator.

Where vertical starts
One toggle. Everything follows.
Pick Portrait when you create the video, and everything after it is made for the tall frame: storyboard, stills, clips, captions, export. Nothing is a widescreen shot with the sides cut off.
New video · Format
Landscape · 16:9
(YouTube, long-form)
Portrait · 9:16
(Shorts, Reels, TikTok)
Chosen once, when you create the video.
Native 9:16
Composed vertical, not cropped.
Every shot is planned and drawn for the tall frame, so it looks like it was made for the feed, because it was.
Shots planned for a tall frame
Subjects in the middle of the frame, close and medium shots, comparisons stacked top to bottom.
Captions where you can read them
Captions and overlays stay clear of the top and bottom of the screen, where the app's own buttons sit.
Real footage found in portrait
Stock footage is searched in portrait, so nothing arrives sideways and gets cropped to fit.
Fully hands-off
Just tell Claude to make the video.
Not a template library
Same channel, both formats.
Everything your channel owns carries into a Short: the style, the same characters, the narrator voice. One channel ships long-form episodes and faceless shorts from the same cast.
That's the difference from templated shorts tools: every Short is rendered from its own script, the same way our faceless video generator builds long-form. No shared template library, no auto-posting, no volume spam.
Questions
Questions about AI Shorts generator.
What is an AI Shorts generator?
A tool that produces finished vertical videos for YouTube Shorts, Instagram Reels, and TikTok. Framesail's version is the same thing that makes your long-form videos, script, voiceover, storyboard, and render, composed for the tall frame. Not a template library.
How long can a Short be?
You set the script length — it's a setting, not a mode. The three examples on this page run about 40 seconds each.
Can I turn my long-form video into a Short?
No. Format is chosen per project and fixed once the storyboard exists, because cropping a 16:9 storyboard would ruin every shot. Start a new video on the same channel — same style, same characters, same voice.
Are captions included?
Built in, off by default. Turn them on and you get TikTok-style paging with optional word-level highlight.
What resolution do Shorts export at?
A clean 1080×1920 video with the sound levelled. Post it to Shorts, Reels, TikTok, anywhere.
Does it auto-post to TikTok or YouTube?
No. You download one clean video and publish it yourself — no platform integrations, no scheduling, no watermark.
