How do I stream vertical (9:16) to TikTok?
TikTok LIVE is a portrait experience, so your feed should be 9:16. Either set OBS to a vertical 1080 × 1920 canvas, or keep your landscape stream and add a separate vertical output so you reach TikTok and desktop platforms in one session.
Set a 9:16 canvas in OBS
In OBS, open Settings → Video and set both the Base (Canvas) and Output (Scaled) resolution to 1080 × 1920. Lay your scene out for portrait — a tall camera, chat and alerts stacked vertically — so nothing important sits where TikTok crops or overlays its UI.
- Canvas & output: 1080 × 1920 (9:16)
- Bitrate: around 4,000–6,000 Kbps, 2-second keyframe
- Keep key elements out of the top/bottom TikTok UI zones
Landscape and vertical at the same time
If you also stream to Twitch or YouTube in 16:9, you don’t have to choose. In Stream Repeater, add a free vertical companion channel to your landscape stream — your overlays and game scenes re-render in portrait for it — so one broadcast reaches TikTok in 9:16 and your desktop platforms in 16:9.
Send it to TikTok (and everywhere else)
Point OBS at Stream Repeater once and add TikTok as a destination with its server URL and stream key. We relay the feed copy-first — no re-encoding on our side — so adding TikTok costs you no extra upload.
Frequently asked questions
What resolution is TikTok LIVE?
TikTok LIVE is portrait 9:16 — a 1080 × 1920 canvas fills the screen. A landscape feed will be pillar-boxed with black bars.
Can I stream to TikTok and Twitch at the same time?
Yes. Send one feed to Stream Repeater and add both as destinations; a free vertical companion channel gives TikTok a proper 9:16 feed while Twitch stays 16:9.
