The crop moves with the subject
Face and scene tracking place the 9:16 window on the face on screen and move it when the person moves; automatic zooms are bounded between x1.0 and x1.6.
VERTICAL VIDEO MAKER
Convert a horizontal recording into 9:16 clips that follow the face.
An auto reframe tool for talking videos: a 9:16 crop moved around the face on screen, applied to short passages of a horizontal video, not the whole file resized. That is the framing step of the shortshort studio, the same studio as on every other page, and each passage leaves it as its own MP4, 1080 x 1920 in 9:16 or 1080 x 1350 in 4:5.

Vertical video maker: the short answer
shortshort turns a 16:9 recording into 9:16 clips at 1080 x 1920: the crop follows the face on screen, zooms stay between x1.0 and x1.6, framing is automatic.
Example with shortshort: a 22-minute product demo becomes 4 shorts of about 35 seconds, for 22 credits on the Starter plan.

Why the studio fits this job
The rules of the studio that matter most here.
Wide shots are not forced into a strip
A slide, a screen or a wide scene is detected and kept full-frame inside the vertical canvas rather than cropped through its middle.
Framing is automatic
The crop is set by the tracker, with no sliders to drag or lock; in the editor, which comes with a free account, you change the bounds, captions and title of each proposed clip.
What the studio does to the video
An illustration of the rule at work; the community below shows the real thing.
How to do it
Four steps. About two minutes of your time; the processing itself runs on our servers and depends on the length of the video.
- 01Open the studio and add a horizontal MP4, MOV or WebM of up to 2 GB
- 02Let the AI pick passages aimed at 15 to 90 seconds with a free account, then adjust their bounds in the editor
- 03Check the crop in the preview
- 04Export each clip as an MP4, 9:16 at 1080 x 1920 or 4:5 at 1080 x 1350
What this page does not promise
What the search term usually implies, and the studio does not do.
The whole video is not converted: the output is a set of separate 9:16 clips, each a short passage, not a vertical version of the full recording.
No 1:1 or 16:9 output: clips come out in 9:16 at 1080 x 1920, or in 4:5 at 1080 x 1350 for the Instagram feed.

Questions people ask
Can I convert my entire 40-minute video to vertical?
No. shortshort produces shorts aimed at 15 to 90 seconds, each cropped to 9:16 around a chosen passage, and exports them as separate MP4s. It is not a batch converter for a full-length file.
Is 9:16 1080 x 1920?
9:16 is a shape, not a size: 1080 x 1920 is the usual full-HD frame with that shape, since 1080 divided by 1920 equals 9 divided by 16, and it is the size shortshort exports in 9:16. Other 9:16 sizes exist, such as 720 x 1280 or 2160 x 3840, but the studio has no 4K option. Its other format, 4:5, comes out at 1080 x 1350.
What resolution is the vertical output?
1080 by 1920 pixels in 9:16, or 1080 by 1350 in 4:5, H.264 in an MP4, at 30 frames per second. There is no 4K option and no higher frame rate, whatever the resolution of the source.
Does it work on a video where the person walks around?
Yes. Face tracking moves the crop as the person moves across the frame, and scene detection resets it when the recording cuts to a new shot. The zoom never goes under x1.0 or past x1.6. In 9:16, on a tracked face it stays at x1.0 or x1.04 for each shot, with gentle push-ins up to about x1.11; in 4:5, the shot zoom brings a small face to about 20% of the frame height, at most x1.4. If the track drifts, there is no manual correction.
Can I use the editor without the AI?
Not from a bare video: the studio does not cut a video without the AI proposals. The editor opens on the clips the AI proposes: you then move their bounds, write the title and description, fix the caption words or import an SRT file, and choose the caption style. It needs a free account, which comes with 30 credits and no card. The crop is placed by the tracker, not by hand. The AI analysis, including the transcription that times the captions, is the part that spends credits; editing and exporting the MP4 cost none.
Is a square or 4:5 version available?
4:5, yes; square, no. Choose 4:5 at export and the whole series renders at 1080 x 1350, on every plan, at no credit cost. Each clip is framed again for the 4:5 frame, with the face tracked anew rather than the 9:16 crop made wider. There is no 1:1 or 16:9 export.
Is this a separate vertical video tool?
No. It is the framing step of the shortshort studio, the same product as on every tools page here, reached from the search term people use for it.
