TikTok LIVE Studio Doesn't See a Vertical Source: What to Check

Why TikTok LIVE Studio Doesn't See a Vertical Source

The problem may not be related to the vertical format itself, but to the video signal. TikTok LIVE Studio recognizes a source as a camera, window, screen, or other connected device. The 9:16 aspect ratio only determines how the image will look in the scene.

If the source doesn't appear in the list, most often the program hasn't been granted access to it. If the source is added but the preview window is empty or only a fragment of the frame is visible, the cause is usually the selected scene, permissions, the camera being in use, or an incorrect canvas size.

First, determine which situation you're dealing with: the source isn't in the list, it's added with a black screen, or the vertical video is being cropped. Each case requires a separate check.

Check the Scene and Source Position

In LIVE Studio, sources are tied to a specific scene. If a vertical camera or capture is added to one scene but the stream is launched from another, they won't appear in the working area. Switch between scenes and make sure the source is added to the active one.

The added element may also end up behind another layer, outside the canvas, or hidden. Check its visibility and layer order. If the program has a position lock, temporarily disable it. Then move the source to the center of the working area and fit it to the frame.

You shouldn't create several identical sources in a row. First delete the non-working element, restart the program, and add the device again. This helps rule out a specific scene error or a frozen video signal.

Check the Camera, Phone, and Permissions

The camera won't be available in TikTok LIVE Studio if another program is already using it. Close video calling, screen recording, and editing apps, and also stop the virtual camera if you no longer need it. Then restart LIVE Studio and open the device list again.

In your operating system settings, check the permission to use the camera. Access must be allowed both for apps in general and for desktop programs, if such a setting is available. The microphone is checked separately: its absence usually doesn't hide the video camera, but it can create the impression that the source isn't working properly.

If the vertical signal is coming from a smartphone, check the cable, the connection, and the intermediary app. Simply enabling portrait orientation on the phone doesn't guarantee that the computer will receive the video stream. The device must be recognized by the system, and the image must open in a test camera app.

Clarify the Frame Format and Orientation

A source with a resolution of 1080 by 1920 can work correctly even in a scene of a different size, but the image will have letterboxing or cropping. If the vertical frame looks like a narrow strip, is stretched, or only part of it is visible, change the orientation and size of the working area in the scene settings, if such parameters are available in your version of the program.

After that, fit the source into the canvas rather than stretching it along just one side. When resizing manually, it's easy to break the proportions. If LIVE Studio doesn't have a separate vertical mode, the source can still be displayed on a horizontal canvas — this is a layout limitation, not a missing video signal.

When capturing a window, make sure you've selected the right window, not a minimized one or another copy of it. Some programs change the window title after launch, so the source has to be selected again.

What to Do About a Black Screen

A black screen means the source is added but the image isn't coming through or can't be displayed. Check whether the camera works in the system app. If there's no image there, the problem is related to the device, cable, driver, or permissions, not to TikTok LIVE Studio.

If the camera works in other apps, try changing its resolution and frame rate to simpler values. The specific available parameters depend on the device. A virtual camera must first be started in the program that generates the signal, and only then selected in LIVE Studio.

A full restart also helps: stop the stream, close LIVE Studio, disconnect and reconnect the camera, then open the program. Check for updates to LIVE Studio and the device driver, but don't change several settings at once — that makes it harder to identify the cause of the failure.

In Short: The Order of Steps

1. Determine whether the source is missing from the list or displayed with a black screen.
2. Check the active scene, visibility, layer order, and source position.
3. Close other apps using the camera and allow access to it in the system.
4. Check the signal from the phone, camera, or virtual device separately.
5. Set up the vertical orientation of the canvas and fit the source into the frame.
6. If the problem persists, restart the program, reconnect the device, and update the necessary components.
