Turn a tweet into a YouTube Short
YouTube treats any video under 60 seconds with a vertical aspect ratio as a Short, so hitting 9:16 exactly is what keeps it out of the regular player with black bars either side. Shorts also autoplay muted and loop, which suits a silent tweet animation.
This page renders at 1080 by 1920 with a longer hold than the Reels preset, because Shorts viewers arrive mid-loop and need the card on screen long enough to read from any entry point.
Questions
- What makes YouTube treat my upload as a Short?
- A vertical or square aspect ratio and a length under 60 seconds. A 1080 by 1920 export satisfies both.
- Do Shorts need sound?
- No. They autoplay muted, so a silent tweet animation is normal. Add music in the YouTube editor afterwards if you want it.
- Why is this preset longer than the others?
- Shorts loop and viewers join partway through, so the readable card needs to stay on screen long enough to be caught from any point in the loop.
