How to Stream 16:9 Horizontal and 9:16 Vertical at the Same Time from OBS Studio
TikTok Live and YouTube Shorts reward 9:16 vertical video with massive organic reach, while Twitch and Kick require 16:9 widescreen. Here is how to configure a dual-format workflow without dropping frames.
How Vertical Live Feeds Drive Top-of-Funnel Discovery
On Twitch and Kick, viewers browse categories intentionally. On TikTok Live and YouTube Shorts, the algorithm pushes vertical 9:16 live broadcasts directly between short-form videos on the For You feed. Streamers who add a native 9:16 vertical output alongside their 16:9 desktop stream routinely see 2x to 4x more unique concurrent viewers per session.
Setting Up Dual Format Output in Restream Studio Pro ($19/mo)
Instead of running two separate computers or overloading your local GPU with multiple simultaneous RTMP encodes, Restream Studio's Dual Format Streaming lets Pro ($19/mo) and Ultra ($40/mo) broadcasters route horizontal 16:9 feeds to desktop platforms (YouTube, Twitch, Kick, Facebook, X, LinkedIn) while simultaneously feeding 9:16 vertical endpoints (TikTok Live, YouTube Shorts, Instagram Reels).
Framing Your Facecam and Gameplay for 9:16 Viewers
For gaming streams, the highest-converting 9:16 layout stacks your facecam in the top third of the vertical frame (1080x640) and centers your gameplay action in the lower two-thirds (1080x1280). Keep your sub alerts and chat boxes above the bottom 300 pixels so TikTok's mobile interface never obscures them.
Frequently Asked Questions
Does streaming 16:9 and 9:16 at the same time require two webcams?
No. Your single webcam or capture card source can be used across both your 16:9 horizontal and 9:16 vertical layouts simultaneously.
