How do I stream vertical and landscape at the same time?

Landscape rules the big screens; vertical owns the phone. Reaching both used to mean two separate streams or re-cropping later. With a companion vertical channel you can send both aspect ratios out live, at the same time.

Your phone sends one stream to the cloud relay. Stream Repeater fans it out to all destinations without heating up your phone or using extra mobile data.

Produce both shapes

Your landscape (16:9) feed goes out as normal. For vertical, add a 9:16 output — most encoders can do this with a vertical canvas or a dual-output/second scene, framed for a phone.

Because the relay is copy-first, Stream Repeater doesn’t reshape your video — you send the exact aspect ratio each destination should receive, and it’s passed through untouched.

Add a companion vertical channel

In the dashboard, add a vertical companion channel alongside your main one. It’s built for 9:16 and points at your vertical-native platforms — TikTok, YouTube Shorts, Instagram Reels — while your main channel keeps serving Twitch and YouTube in landscape.

Companion channels don’t count toward your plan’s channel limit, so going vertical as well as landscape doesn’t cost you an extra channel slot.

Overlays that fit the frame

Your Stream Games scene and overlays render in portrait for the vertical channel, so alerts, chat and game boards sit correctly in a 9:16 frame instead of being letterboxed from a landscape layout.

Frequently asked questions

Does a vertical channel use up one of my channels?

No. A companion vertical channel is excluded from your plan’s channel limit, so it doesn’t reduce how many main channels you can run.

Will Stream Repeater crop my landscape stream to vertical?

No. The relay is copy-first and never reshapes video — you produce the 9:16 feed in your encoder and it’s passed through as-is.

Which platforms take the vertical feed?

Vertical-native destinations like TikTok, YouTube Shorts and Instagram Reels; your landscape channel keeps serving Twitch and YouTube.
