What works in a vertical frame?

A 9:16 frame is narrow, close and fast. One subject, one action and a camera that stays with it will read better than a wide establishing shot. Felo lets you describe the vertical composition directly, so the subject fills the frame from the start.

  • 1

    One subject, centered or moving through a tall frame.

  • 2

    Close, legible action that reads in a few seconds.

  • 3

    Camera moves that follow the subject up, down or through.

  • 4

    Sound and music directed in the prompt.

How to make a vertical video

Three steps from a prompt to a 9:16 clip.

  1. Write for the frame

    Name the subject, what it does and what fills the top and bottom of the frame. Keep to one action.

  2. Set 9:16 and duration

    Choose the vertical ratio, then set length and resolution. Short clips work best when the action resolves.

  3. Review and refine

    Check that the subject stays in frame, then ask for a change in the same thread.

Where vertical clips go

Compose for the full screen first, instead of cropping a widescreen shot later.

  • Shorts and Reels

    Generate a 9:16 clip built around one action and a clear subject.

  • Stories and social ads

    Make a short vertical beat that fills the frame without letterboxing.

  • Backgrounds for vertical text

    Create motion or atmosphere to place under captions in your editor.

Vertical video model directory

Felo supports 9:16 natively, so the clip is generated in the tall frame instead of being cropped from a widescreen render. MiniMax H3 is available today; more models are on the way.

How to write a vertical video prompt

Vertical prompts need a tighter composition. Describe what the camera sees top to bottom, and keep the action readable without a wide background.

Framing
Where the subject sits in the tall frame and how much of the body or object is visible.
Action
One clear movement that starts and resolves inside the clip.
Camera
Follow, tilt, push in or orbit — and keep the subject inside the 9:16 crop.
Background
What fills the space above and below the subject without competing for attention.
Sound
Ambience, effects or music that fit the pace of the clip.
Example prompt

“Photoreal miniature food comedy in 9:16. A thumb-sized raccoon hugs a blueberry larger than its head on a giant pancake. It takes two quick steps toward the edge; one paw sticks in the maple syrup, the syrup stretches and snaps, launching the raccoon into a cloud of whipped cream. The camera tracks at pancake height, then tilts up to follow the arc and settles as the raccoon lands. No text, no hands, no extra animals. Overall soundscape: tiny paw taps, sticky syrup, an elastic twang and a soft cream poof. Non-diegetic music: light pizzicato strings.”

Frequently asked questions

What is an AI vertical video generator?
It generates video in a 9:16 frame for short-form feeds, stories and mobile screens. Felo creates the clip from a text prompt or a reference image.
Does Felo crop widescreen video to 9:16?
No. 9:16 is one of six supported ratios, and the clip is generated in the vertical frame.
What should I put in a 9:16 prompt?
One subject, one action, the framing top to bottom, a camera move that keeps the subject in frame, and the sound you want.
How long can a vertical clip be?
4 to 30 seconds at 480P or 768P, and 4 to 15 seconds at 1080P or 2K.
Can I generate a vertical video from an image?
Yes. Use the image as the first frame, or as the first and last frame, and describe the motion between them.
Can I add captions or a voiceover?
No. Felo does not add captions, subtitles or a separate voiceover track. You can direct ambience, effects and music in the prompt, and add captions later in a video editor.
What resolution are vertical clips?
Choose 480P or 768P for drafts, or 1080P or 2K for the final clip. 1080P and 2K are limited to 4–15 seconds.
Where can I use a vertical clip?
Anywhere that accepts a 9:16 video file: short-form feeds, stories, mobile ads or a vertical screen. Felo produces the clip; publishing is up to you.
How much does Felo vertical video cost?
Video generations use Felo points. The pricing page lists the points included with each plan.
Why generate in 9:16 instead of cropping a widescreen clip?
A generated 9:16 frame is composed for the phone: the subject, headroom and background are chosen for the vertical shape. Cropping a widescreen clip discards the sides and can cut the subject.
Can I generate a square or 3:4 vertical clip?
Yes. MiniMax H3 supports 21:9, 16:9, 4:3, 1:1, 3:4 and 9:16. Use 9:16 for full-screen vertical, and 1:1 or 3:4 for feed posts.
