Build a clean, vertical stream for TikTok Shop using OBS Studio, Aitum Vertical and TikFinity. This guide covers install, scenes, audio, alerts, and going live via TikTok Shop LIVE Manager.



Quick links


What youā€™ll need


  • PC or Mac that can encode video (most modern systems are fine)

  • A camera (webcam, mirrorless/DSLR via capture card, or smartphone as a camera)

  • A microphone

  • Optional: headset (recommended if youā€™ll route audio), VB-Audio Virtual Cable (Windows), Nvidia Broadcast (Windows + NVIDIA GPU)


1) Install and prepare OBS + Aitum Vertical

  1. Install OBS Studio then install Aitum Vertical. Restart OBS if prompted.

  2. In OBS, Profile ā†’ New (e.g., ā€œTikTok Shop Streamingā€) and tick to run the auto-config wizard. Optimise for ā€œI will only be using the virtual camera.ā€

  3. Scene Collection ā†’ New (e.g., ā€œTikTok Shop Scenesā€). Youā€™ll now see a Landscape and a Vertical canvas (Aitum panels). If the vertical panels arenā€™t visible: View ā†’ Docks and enable the Aitum Vertical items.


2) Configure audio in OBS

  1. Settings ā†’ Audio. Under Mic/Auxiliary, pick your microphone.

  2. (Optional) Add a simple noise suppression filter (Filters ā†’ + ā†’ Noise Suppression).

  3. If you plan to use Nvidia Broadcast noise removal, set your Windows input device to Nvidia Broadcast and select that as your mic in TikTok Shop LIVE Manager later.


3) Create your vertical scenes

Weā€™ll make two common scenes in the Vertical canvas.

  1. ā€œFull Camera ā€“ Verticalā€: Sources ā†’ + ā†’ Video Capture Device ā†’ select your camera ā†’ set Resolution/FPS Type to Custom (e.g., 1920Ɨ1080) ā†’ OK. Right-click ā†’ Transform ā†’ Fit to Screen, then right-click ā†’ Transform ā†’ Center Horizontally. Lock the source.

  2. ā€œCamera + Display ā€“ Verticalā€: Add your camera again (Add Existing), place it in the top third. Add a Display Capture (or Window Capture), then either Transform ā†’ Fill to Screen (crops the sides) or Fit to Screen (letterboxes). Optionally add an Image source to fill the lower third (remember chat usually covers the bottom area). Lock sources and use sensible names.


4) Send your video to TikTok Shop LIVE Manager

  1. In Aitum Vertical, open the settings (cog) and ensure Virtual Camera = Vertical (1080Ɨ1920).

  2. Click the Aitum ā€œVertical Virtual Cameraā€ button to start it.

  3. In your browser, open TikTok Shop LIVE Manager ā†’ Go Live Now ā†’ choose Practice to test.

  4. Video Source = OBS Virtual Camera. Audio Source = your microphone for now (you may switch to VB-Cable later). Youā€™ll hear yourself while the preview tab is focusedā€”thatā€™s expected.

  5. Switch scenes in OBS; the preview in LIVE Manager will follow in real time.


Open OBS before your web browser.Ā This ensures OBS ā€œownsā€ the camera so Chrome/Edge/Safari canā€™t steal it.


5) Add on-screen alerts with TikFinity

  1. Open TikFinity (desktop app on Windows, web app on macOS). Log in with TikTok.

  2. Go to Actions & Events ā†’ import the predefined alerts if prompted. Copy the ā€œScreen 1ā€ overlay URL.

  3. In OBS Vertical scenes, add Sources ā†’ + ā†’ Browser ā†’ New. Paste the URL, start with 600Ɨ300, and tick Shut down source when not visible. Place it where chat wonā€™t cover it; lock it.

  4. Add the same Browser source to your other vertical scene (Add Existing). Test in TikFinity via the play/simulate buttons.

  5. Create a simple Shop alert: Action = shows product image/name; Event = ā€œPurchasing a product from TikTok Shop.ā€ Leave keyword blank to trigger on any showcase purchase.


6) Route music and computer audio (pro method, Windows)

Basic method: play music from speakers near your mic. Pro method: send audio digitally.

  1. Install VB-Audio Virtual Cable, restart Windows.

  2. OBS ā†’ Settings ā†’ Audio ā†’ Advanced: Monitoring Device = ā€œCABLE Input (VB-Audio Virtual Cable)ā€. OK.

  3. In the Mixer: for Mic and Desktop Audio, click the three dots ā†’ Advanced Audio Properties ā†’ set Audio Monitoring = ā€œMonitor Only (mute output)ā€. This sends those signals into VB-Cable.

  4. In TikTok Shop LIVE Manager (Practice), set Audio Source = ā€œCABLE Output (VB-Audio Virtual Cable)ā€. Your audience now hears your mic + desktop audio cleanly.

  5. To play a promo video: create a new Vertical scene ā†’ Media Source (pick file, usually not looped) ā†’ in Advanced Audio Properties set it to ā€œMonitor Only (mute output)ā€.


7) Optional: cleaner mic with Nvidia Broadcast (Windows + NVIDIA GPU)

Install Nvidia Broadcast, select your real mic as input, enable Noise Removal and Room Echo Removal. In LIVE Manager choose ā€œNVIDIA Broadcastā€ as your microphone instead of the raw mic.


Go-live checklist

  • Start Aitum Verticalā€™s Vertical Virtual Camera.

  • Select ā€œOBS Virtual Cameraā€ in TikTok Shop LIVE Manager.

  • Open TikFinity and ensure itā€™s connected (Setup ā†’ Connect if needed), then minimise.

  • Choose your Audio Source (Mic, Nvidia Broadcast, or VB-Cable Output).

  • Keep chat coverage in mind (bottom third); lock sources to avoid accidental moves.


Troubleshooting

  • Camera ā€œbusyā€ in the browser: you launched the browser first. Close it, start OBS, then reopen the browser.

  • Alerts not showing: in OBS, the Browser source must be above other sources and not hidden.

  • No audio with VB-Cable: re-check Monitoring Device, and that relevant sources are set to ā€œMonitor Only (mute output)ā€.


Next steps

Add more scenes (e.g., product close-ups), refine your image assets, and tailor TikFinity alerts. When youā€™re happy, exit Practice and go live.
