Pick the shape first
You choose vertical 9:16 or horizontal 16:9 before you press Create. The price is the same, and the shape cannot be changed afterwards.
Describe for a tall frame
- Put the subject in the centre, with room above and below
- Use tall subjects: a person standing, a tower, a pour of liquid
- Use slow zooms and tilts rather than wide pans
Where vertical works best
- Reels, Stories, TikTok and Shorts
- Phone messages
- Mobile ads
Use both shapes
If you need the same idea in both shapes, make two videos. Each is priced by its length.
A quick framing checklist
- Keep the main subject in the middle third of the frame
- Leave space at the top and bottom where apps place buttons and captions
- Prefer subjects that are tall or centred
- Avoid very wide scenes that lose detail on a narrow screen
