How to repurpose one video for TikTok, Reels, Shorts and YouTube
Shoot once, post everywhere: which format each platform wants, why cropping loses the shot, and how to record the vertical and horizontal cut together.
By the Dualsy team ·
Most creators post the same idea in several places. The hard part is not the posting, it is the format: short-form apps are portrait, YouTube is landscape, and a video framed for one rarely works in the other.
What each platform wants
- TikTok, Instagram Reels and YouTube Shorts: portrait, 9:16.
- YouTube and most websites: landscape, 16:9.
- Instagram feed posts: square 1:1 or 4:5.
Why cropping is not enough
Cutting a 9:16 slice out of a 16:9 video keeps less than a third of the width. Hands, products and second people fall out of frame, and the moment you liked most may not fit at all.
Record both cuts at once
Open DUAL CAM
The main frame and a second window, each with its own aspect ratio.
Set 9:16 and 16:9
Portrait for short-form, landscape for YouTube.
Frame for both
Keep the subject in the centre third, the part both frames share.
Post each file where it belongs
Two files from one take, one per platform type.
Landscape + portrait
One take, a 9:16 file and a 16:9 file.
Front + back
The view and you, in the same moment.
A posting routine that holds up
- Write captions per platform; the same words rarely fit all of them.
- Post the portrait cut to the short-form apps first, the landscape cut where people watch longer.
- Keep the original files: a later compilation needs the full-quality takes.
