How to stream 16:9 and 9:16 at once with one overlay link

Streaming to a wide and a tall feed usually means two overlays and two scene collections. With Kloot it is one link. Add it to your 1920×1080 canvas and to your 1080×1920 canvas; each copy measures its own frame and lays every tool out for that shape. One key press plays in both.

Can one overlay work in 16:9 and 9:16 at the same time?

Yes, with Kloot. Add the same overlay link as a 1920×1080 browser source on your main canvas and a 1080×1920 source on your vertical canvas. Each copy detects its own shape and lays tools out for it. The panel previews both side by side, and one key press plays in both.

Same overlay link, same state — a key plays in both.

What you’ll build

One overlay link driving your 16:9 and 9:16 feeds, previewed side by side in the panel.

Step by step

  1. 1

    Copy your overlay link

    In the top bar’s copy menu, choose Copy for 1920×1080 or Copy for 1080×1920. Both copy the same link; the menu shows the source settings for each size.

  2. 2

    Add it to your 16:9 canvas

    Add a Browser source at 1920 × 1080 on your main canvas. If Kloot is already there, leave it: a 1920×1080 source renders exactly as before.

  3. 3

    Add the same link to your 9:16 canvas

    On your vertical canvas or portrait scene (in OBS, a 1080×1920 canvas or profile), add a Browser source with the same link at 1080 × 1920. Any app with a browser source works the same way, because the overlay only looks at its own size.

    1080 × 1920

    A nearly square source gets the 9:16 layout at 16:9 sizes. If a host reports the wrong size, add &format=portrait to the end of the link.

  4. 4

    Preview both

    In the True preview, choose Both. Each segment shows “live” when a source of that shape is connected. The chooser only changes what the panel shows, never the overlay.

    What you'll see: Two frames side by side; a counter press animates in both.

  5. 5

    Pick a safe-zone profile

    Choose the platform the 9:16 feed goes to: TikTok LIVE, Twitch (mobile), YouTube (vertical feed), Other / unknown or None. The bands are estimates; two sliders adjust the bottom and right ones.

How each tool moves in 9:16

You don’t place anything twice. Each tool has a 9:16 rule.

  • Tickers and lower thirds sit above the bottom band, full width.
  • Counters stay in their top corner below the top band, or move to a row above the bottom band.
  • Polls and giveaway cards centre in the area viewers actually see, with larger text.
  • Screens fill the frame; landscape art is letterboxed on the tool’s colour, never cropped.

Want a tool somewhere else on the phone? Each anchored tool’s editor has an “In 9:16” section. Same as 16:9 uses the rule above and Hide in 9:16 is Free; Custom for 9:16, your own spot and size, is Pro ($9/month).

If the 9:16 feed looks wrong

Check these.

  • Both feeds show the 16:9 layout. The vertical source is not 1080×1920. Fix the size, or add &format=portrait.
  • Text is tiny on the phone. The source was scaled down in the canvas. Reset its transform so it fills the 1080×1920 frame.
  • The chooser says “not connected” on 9:16. The vertical source isn’t loaded. Refresh the source, or check it sits in the scene that is live.

Common mistakes to avoid

  • ✕Making a second Kloot account or overlay for the vertical feed. Use the same link.
  • ✕Expecting the panel’s 9:16 button to change the overlay. It only changes the preview; the source size decides the shape.

Frequently asked

Do I need two overlays or two scene collections?

No. Kloot uses one link for every shape. You add the same link to each canvas at that canvas’s size, and every tool you add to the deck shows up in both feeds.

Will adding a 9:16 source change my 16:9 overlay?

No. A 1920×1080 source renders exactly as it did before. The 9:16 layout applies only to a source drawn in a tall or square frame.

What is Free and what is Pro?

Shape detection, the 9:16 layout, the side-by-side preview and safe-zone shading are Free. Placing a tool yourself in 9:16 with Custom for 9:16 is Pro, at $9/month or $79/year.

Does Kloot fire tools on its own when someone subs or gifts?

No. Kloot never reads gifts, subs, follows or chat. You fire tools from the panel, your phone or a Stream Deck, and each press plays in both shapes at once.

One overlay.
Both shapes.

The same link lays itself out for 16:9 and 9:16. Detection, the 9:16 layout and the dual preview are Free.
