Stream in dual format on Twitch
Dual format sends horizontal and vertical versions of your stream to Twitch together. Desktop and TV viewers see your horizontal layout. Mobile viewers can watch vertically or rotate their phone for the horizontal view.
Before you begin
Section titled “Before you begin”- Use OBS Studio 32.0.0 or newer and install SE.Live Public Beta. Close OBS before running the SE.Live installer.
- Connect Twitch in Settings → Stream in OBS.
- Check Twitch’s hardware and upload requirements. Dual format is available to all Twitch streamers.
- If you have Aitum Vertical installed, uninstall it before using SE.Live dual format. Running both plugins can cause OBS to crash.
Prepare your vertical layout
Section titled “Prepare your vertical layout”- Create a vertical canvas at 1080 × 1920.
- Add scenes and sources, then arrange your camera, gameplay, and alerts to fit the portrait frame.
- Link your scenes and check both layouts in the preview.
Enable dual format
Section titled “Enable dual format”- Open Settings → Stream in OBS and select Twitch.
- Under Multitrack Video, check Enable Enhanced Broadcasting.
- Open Additional Canvas and select your SE.Live vertical canvas.
- Click Apply, then OK.
Go live and check the result
Section titled “Go live and check the result”Click Start Streaming in OBS. Open your stream on a phone and check it in portrait and landscape. Switch scenes and confirm that the camera, gameplay, and alerts stay in frame.
To return to horizontal-only streaming, set Additional Canvas to None.
Do I need Twitch’s approval to use dual format? Yes — beyond installing SE.Live, you also need to be accepted into Twitch’s own Dual Output Beta. StreamElements doesn’t control that approval; if you stream without it, OBS shows an error when you try to go live. See Twitch’s Dual Output Beta info for how to apply.
OBS is crashing while I use dual format. Try rolling back to OBS 31 — OBS 32 has known stability issues affecting several plugins, including SE.Live.
Known issues
Section titled “Known issues”Deleted canvases can still appear in Twitch’s canvas selection dropdown, marked Inactive. There’s currently no way to remove them — this is a known OBS bug, with no fix ETA yet.
