Start with what “same video” means
You may want the same message and timing, or you may need precisely the same cut in a different frame. Those are different requests. The second can be difficult when a wide shot contains important details at both edges.
Write down what must match: wording, duration, shot order, offer, or ending. Then decide what can change to keep the video readable. You may need a close-up in the vertical version while keeping the wider scene in landscape.
Keep two short format notes
For 9:16, name the subject that must stay in frame. For 16:9, say whether the extra space should reveal context or simply keep the same subject larger. If text sits beside an object, check how that relationship changes.
In Shorty, select the relevant canvas for each edit. Its support for multiple shapes should not be read as a guarantee that every version renders from one request. Prepare and review the required outputs using the options available in your account.
Check the files, not just the labels
A filename ending in “vertical” does not prove the dimensions or composition are right. Open each export. Watch the subject through movement, read the captions, and confirm the closing line has enough time on screen.
Keep a delivery list with one row per format and an approval mark beside each file. This sounds small, but it prevents the familiar mistake of sending a beautiful landscape cut to a placement that needed portrait. The point of automation is a reliable handoff, not merely a faster render.
A brief to adapt to your footage
Example direction. Replace the subject, shots, and wording with your own.
Create the landscape version of this product story in 16:9. Keep the same message and approved wording as the vertical brief. Use the wider workshop view where it adds context. Ensure the product and hands remain visible throughout the demonstration.
