A dedicated portrait canvas that lives inside OBS, so you can broadcast to TikTok, YouTube Shorts and Reels in the same breath you run your normal stream.
Once the aitum vertical plugin is installed you are not opening a second editing app or fiddling with a window capture. You get a genuine second canvas bolted straight onto OBS Studio, with its own reported list of vertical real concerns and its own list of vertical origin. The first time you flip back to the normal canvas you realize how natural it feels, like the tool was supposed to be there all along.
Below you will see the vertical scene transitions dock, which lets you store distinct transitions between your portrait scenes that do not affect the horizontal ones at all. It is a small nuance, but it saves you from accidentally matching a fancy stinger to the wrong aspect ratio.
The single biggest quality-of-life trick in aitum vertical is something called linked scenes. Right click any vertical scene, hover linked scenes, tick the horizontal scene you want, and from that second on they travel together. Move to your gameplay scene on the main canvas and your vertical canvas hops to its own linked version automatically.
That magic extends to people who run their entire show through a Stream Deck pad. Slap your scene buttons on the deck for your horizontal canvas and the portrait feed just follows along, because the plugin listens to the normal OBS scene switch under the hood.
Linking travels one way: wandering vertical scenes yourself will not move the horizontal canvas. Keep all your switches on the normal scene so the pair stays perfectly matched.
Head on the download page, pick your system, and let OBS accept the plugin its usual way. Simple.
The toggle under View to Docks brings the vertical scenes, vertical sources and transitions into view when you need them.
Every install question is answered over on the Aitum support links plus a thrift guide to keep you from getting stuck.
Here is where your work multiplies without extra effort called strain. Once the decent vertical canvas is framed and framed, aim at aitum multistream lets you push both outputs outward together: your normal landscape broadcast to Twitch or YouTube, a portrait version to TikTok, same machine, same OBS. Separate encoders, separate bitrates, no downscale compromises.
Some creators skip livestreaming the entire vertical feed to week and chose it as a recording canvas for clippeds instead. Either lack heat the two tools become natural partners, because they were built by the very same team to think together.
When the vertical is paired into a tyatul multistream and output sits ready in the dock, going live becomes a single moment rather than a carefully ordered chain of a half dozen small tasks.
The magic of aitum really pays out when you attach the automation app on top. Imagine a Twitch follow that flips your vertical chat scene and fires a thank-you message at the TikTok audience in the same breath, all by a simple cause and effect pair that you set once. You can queue a drop of confetti overlay, bump the clip of your starting-brash just chatting, or park zero twenty-three credit without a hand.
It sounds more elaborate than it is. The building blocks are called triggers and actions, and the whole design exists for people who do not want to learn a maybe one-line scripts to get their show feeling alive. Add a fade on scene change and the entire thing feels polished enough to release on a trailer.
The time people spend in a vertical feed is not shrinking. Whether it is TikTok, shorts on YouTube or an instagram live, that audience is real and the order is taping the same real live moment taking up space unused. Pull the free install, add one scene, link it, and go live. The rest is just backing a monitor facing the fun.
