Quick answer
A vertical app promo should reveal the product immediately, keep the phone screen large enough to read, and show one complete result. Build for the vertical frame from the beginning instead of cropping a landscape composition after export.
When this workflow is useful
Use short-form promos for feature launches, build-in-public updates, waitlist campaigns, tutorials, app launch announcements, and recurring content. A repeatable scene system makes weekly publishing faster without making every post look identical.

Step-by-step workflow
- Choose one scroll-stopping result. Open on the finished creation, report, transformation, or interaction rather than an empty device or long logo reveal.
- Record a short vertical-friendly flow. Keep taps and interface changes near the central area and remove pauses that do not add understanding.
- Compose for 9:16. Scale the phone for feed viewing and reserve top and bottom areas for platform overlays and captions.
- Add benefit-led text. Use one hook and a small number of supporting labels. Keep every line readable on a real phone.
- Build a batch system. Reuse the background, device treatment, and timing structure while swapping the product moment and hook for each post.
Decisions that improve the result
Pace
Move quickly between ideas but hold the actual product result long enough to understand. Speed is not the same as constant motion.
Captions
Place text away from interface controls and social platform overlays. Review the exported video inside a phone-sized preview.
Trends
Use sounds or formats only when they fit the product. A clear evergreen demonstration can keep working after a trend disappears.
Production checklist
- Vertical composition
- Product visible immediately
- One complete result
- Safe caption placement
- Phone-size review
- Reusable batch template
Frequently asked questions
Can I crop a landscape video?
You can, but a dedicated vertical composition protects the device, interface, and captions more reliably.
How much text should I add?
Use enough to state the benefit and guide the action. If the screen becomes hard to see, the copy is doing too much.
Should every post use a different animation?
No. Consistent visual treatment can build recognition; vary the feature, hook, and result while keeping a stable brand system.
