Choose a short, understandable story moment before changing the aspect ratio. Test whether the important faces, prop and action fit a vertical crop. Reuse shots that survive reframing, and create a new composition only where essential information falls outside the frame. A vertical teaser is an editorial adaptation, not simply a narrower export of every landscape shot.
Find a moment with its own payoff
A two-minute film may rely on information introduced much earlier. A teaser should not require the viewer to know the entire backstory. Select a setup, reveal and response that can be understood together, or use an approved title to supply the missing context. Do not add several unrelated spectacular shots just because they look attractive individually.
For a fantasy wedding, the ring-box surprise and the couple's reaction can form a compact sequence. For travel, arrival at a recognizable destination and a personal response may work better than a rapid list of every location. This is an editing choice; it does not require claiming that the film was generated in one model call.
Test the crop against the action
Review the accepted landscape clips in a suitable editor. Follow the action through the entire shot, not just the first frame. A face that starts inside the vertical area may move out of it. Two people placed far apart may not fit together, and the object that explains their reaction may disappear at the edge.
New vertical insert for the approved teaser: frame the ring box centrally at chest height, with enough clear space above it for a short title added later. The tiny mechanical horse makes one readable turn inside the open box. Keep the established prop design and warm evening lighting. Compose for a narrow phone view; avoid placing essential action near either side edge.
Use a new shot only when the existing clip cannot be adapted cleanly. This original brief is not a promise of automatic smart reframing or platform-native caption layout. Use the controls actually available and complete external editing where necessary.
Decide between crop, adaptation and regeneration
A crop is appropriate when the scene's important information already fits. An adaptation may use a different shot order, a closer insert or a short explanatory title. Regeneration is appropriate when neither option preserves the intended story. Do not pay to recreate a whole film merely because one establishing shot is too wide.
Runway's image-to-video guidance explains that the input image provides the composition. The practical implication for this project is to prepare the intended narrow composition before generating a replacement, not assume a landscape reference will automatically become a useful vertical view.
- Choose a teaser moment with a readable outcome.
- Mark the essential face, object and movement in each shot.
- Test the vertical view across the full duration.
- Reorder or replace only shots that lose important information.
- Add titles outside key faces and actions.
- Watch the exported teaser on a phone with and without sound.
Check the final communication
If the teaser promotes a platform, distinguish a fictional sample from an actual customer wedding. Say how it was made without implying all outputs are identical or effortless. Keep any call to action short enough to understand after the visual payoff. A complete ending is more useful than a abrupt crop followed by a crowded screen of claims.
The exact safe area depends on the publication platform and its interface. Check the current upload preview instead of using one permanent rule for every social app. Preserve a clean version without embedded interface elements so future edits remain possible.
Can I just stretch the landscape image vertically?
No. Nonuniform stretching distorts faces and props. Crop, recompose or regenerate a suitable shot rather than changing physical proportions.
Will a new vertical shot use points?
Generation is a separate task with its displayed quote. Review that quote in Portrait Film; a free external crop and a newly generated shot are not the same operation.
