Changing the shape changes the information
In the wide version, two people can sit comfortably across the frame. In the vertical version, one may disappear. A title that sits neatly beside a product can cover it after a crop. Resizing changes what the viewer sees, not just the file dimensions.
Before editing, identify what must remain visible: a face, both hands, the product label, or the entire screen. If a shot cannot carry that information in the new shape, use a different shot or rethink the layout.
Build separate deliverables around one idea
Keep a short master brief for the story, then add format-specific notes. Shorty supports several canvases, including 9:16, 1:1, and 16:9. Prepare each required output deliberately and check the current controls and plan limits for batching.
Do not assume that supporting several canvases means a single request produces every format at once. Label each requested version clearly. The vertical brief might favour a close-up, while the landscape brief keeps the wider context.
Review the edges
Watch the beginning and end of every moving shot, not just a still from its middle. A hand may enter from the side or the subject may walk out of a safe crop. Check text on the smallest screen where the video will be viewed.
Use a simple delivery checklist: correct shape, subject visible, text readable, ending intact, approved filename. Keep the source material so later versions can be rebuilt cleanly. A good repurpose preserves the meaning, even when it changes some of the pictures.
A brief to adapt to your footage
Example direction. Replace the subject, shots, and wording with your own.
Create a 9:16 version of this demonstration. Keep both hands and the product visible during the main action. If the wide shot cannot fit clearly, use the supplied close-up. Reposition text so it does not cover the action. Preserve the ending.
