Quick answer
Treat 9:16 as a new composition, not a center crop. For YouTube Live, creators can now deliver horizontal and vertical versions together and choose center crop, fit-to-phone-width or stacked layouts.
What you need
- 16:9 source recording
- Vertical template
- Caption-safe composition
Verification: Current YouTube Help documentation for vertical and horizontal live layouts.

YouTube Live can now publish horizontal and vertical together
YouTube's current Live Control Room supports simultaneous horizontal and vertical live formats. The vertical layout can use Center crop, Fit to phone width or Stacked, and encoder workflows can use a second stream key for the vertical feed.
Why this matters
For launch streams, you may not need to build a separate vertical live production from scratch. Decide whether YouTube's layout options are good enough before duplicating the whole encoder workflow.

Do not center-crop a 16:9 stream and call it done
Vertical content needs a new composition. Preserve the gameplay subject, keep captions out of UI-heavy zones and decide whether facecam deserves its own area.
Use a simple 9:16 hierarchy
- 01
Hook
The first frame should communicate why the moment matters.
- 02
Gameplay focus
Crop around the action, not around the center of the original frame.
- 03
Captions
Keep subtitles readable and away from platform UI zones.
- 04
Payoff
End once the moment lands. Do not stretch a 15-second idea to 40 seconds.
Create one clip, then adapt the wrapper

| Element | Keep consistent | Adapt |

| Core clip | Yes | Only crop if needed |
| Captions | Style | Position for platform UI |
| Intro text | Message | Length / placement |
| CTA | Tone | Platform-specific |
Build the workflow around selection
Quality filter
A clip should work for someone who did not watch the stream. If it needs 30 seconds of explanation before the payoff, it is probably not a short.
