Vertical 9:16 video is a useful starting format for short social content, but duration and safe areas depend on the destination. Start with one viewer problem, show a concrete example, add readable captions and end with one next step. Verify each channel’s current requirements before publishing.
What to check
- Choose one audience, one message and one next action.
- Keep captions readable within platform safe areas.
- Check music rights, thumbnails and mobile playback before publication.
