TikTok Live is built mouth-first for phones, but streaming from a PC with OBS unlocks overlays, multiple scenes, better audio, and desktop gameplay. The catch is that TikTok gates PC streaming behind eligibility rules and a slightly hidden stream key. This guide walks through the requirements, the setup, and the encoder settings that keep a vertical stream smooth.
What you need before you start
TikTok typically requires an account to meet a follower threshold and be in good standing before it grants access to LIVE, and PC/third-party streaming usually needs LIVE Studio access or a stream key from the creator tools. Requirements shift over time, so confirm your account shows a “Go LIVE” option on desktop before investing setup time.
| Setting | Recommended value | Why |
|---|---|---|
| Canvas / output resolution | 1080×1920 (vertical) | Matches TikTok’s full-screen phone layout |
| Frame rate | 30 fps | Stable for mobile viewers on cellular |
| Bitrate | 4,000–6,000 kbps | Sharp 1080p vertical without overloading uploads |
| Keyframe interval | 2 seconds | Required by most RTMP ingest servers |
| Encoder | NVENC / hardware | Frees the CPU for your game |
Configure OBS for a vertical canvas
In OBS settings, set both base and output resolution to 1080×1920 so your entire layout is vertical. This is the single biggest difference from a normal Twitch setup — a horizontal 16:9 stream will show up letterboxed with black bars and look amateur. Build your scene around the tall frame: gameplay up top, facecam and alerts stacked below.
Enter the stream key
Retrieve the server URL and stream key from TikTok’s LIVE Studio or creator streaming page, then in OBS choose “Custom” service under Stream settings and paste both. Never share this key publicly; anyone with it can broadcast to your channel.
Dial in encoder settings
Use a hardware encoder (NVENC on NVIDIA, AMF on AMD) so gameplay stays responsive. A bitrate of 4,000–6,000 kbps is plenty for vertical 1080p30; going higher risks buffering for mobile viewers without a visible quality gain. Keep the keyframe interval at 2 seconds or the ingest server may reject the stream.
Test privately first
Run a short private or off-peak test to confirm audio sync, that your overlays sit inside the safe zone away from TikTok’s UI, and that comments are visible. Fixing framing live in front of an audience never looks good.
Design around TikTok’s on-screen interface
TikTok Live layers its own buttons, comments, and gift animations over your video, and they occupy predictable zones. Comments scroll up the bottom-left, gift effects burst across the lower third, and interaction buttons sit along the right edge. If you place your facecam, alerts, or key text in those areas, TikTok’s UI will bury them. Treat the center and upper portion of the vertical frame as your safe zone and keep essential elements there.
Because the layout is so tall, resist the urge to cram it. A clean vertical stream usually stacks gameplay in the top 55–65% of the frame and a facecam plus a slim label in the middle, leaving the bottom third to TikTok’s own comment feed. Test with a phone in hand during your private run so you see exactly what viewers see, including how gifts and comments cover your scene. A layout that looks balanced in OBS can be half-hidden once the live UI loads, so verify on an actual device before your first real broadcast.
Frequently asked questions
Why can’t I find my TikTok stream key?
PC streaming access is gated by account eligibility. If the LIVE Studio or stream-key option is missing, your account likely has not met the follower or standing requirements yet, or the feature is not rolled out to your region.
Can I stream horizontal gameplay to TikTok Live?
You can, but it will appear small and letterboxed. A vertical 1080×1920 canvas fills the screen and performs far better, so crop or reframe your gameplay for the tall format.
Bottom line
Streaming to TikTok Live from a PC is mostly about two things: a vertical 1080×1920 canvas and a hardware-encoded 4–6 Mbps feed at 30 fps. Confirm your account is eligible, paste the stream key into OBS as a custom service, test privately, and you get all the polish of a desktop setup on TikTok’s mobile-first stage.
