OBSBOT Tiny 3 A/V Sync & Latency Test

OBSBOT Tiny 3 A/V Sync Test: Measure Audio Offset with AI PTZ Webcam

Start by deciding whether your stream uses the Tiny 3 as a fixed camera or an AI-tracked camera. Tiny 3 is a 4K AI-powered PTZ webcam built around a 1/1.28" 50MP CMOS sensor, with 4K at 30fps and 1080p at 120fps video modes.¹ Its AI Tracking 2.0, Voice Tracking, object tracking, and motorized gimbal can keep you framed while you move, but those features add moving parts to an A/V sync test.

For calibration, use the Tiny 3 as a fixed camera. Disable tracking and let the gimbal park before opening this browser test, because the browser receives the video stream that your selected camera mode is producing at that moment.² A stable setup gives you one number to enter in OBS instead of a reading that changes whenever the camera reframes during the clap.

Specifications¹

Connection and browser setup

Open OBSBOT Center and turn AI tracking off before connecting the camera to the browser. Once the camera is parked in a fixed position, close Center before loading this page so its controls do not change tracking, zoom, or framing while you measure. Connect the Tiny 3 with the USB-C to USB-A 3.0 cable or another USB-C 3.0 path, then grant camera and microphone permissions in the browser.³

The camera registers as "OBSBOT Tiny 3" in the browser video input dropdown. If the video dropdown shows more than one OBSBOT entry, keep the same camera mode for all five claps and re-run the test after any tracking, zoom, or resolution change. The browser test measures the active camera stream, not a separate Center preview.

Tracking-off calibration posture

After disabling tracking in OBSBOT Center, close the Center app entirely before loading the test page. This keeps the camera in the tracking-off state and prevents accidental zoom or preset changes during the measurement. With Center closed, the browser is the only application reading from the Tiny 3 camera for the calibration run, which gives you the cleanest signal path for the OBS value you copy from the result.

Tracking-on verification for live streams

If your actual stream uses Voice Tracking or object tracking, run a second five-clap pass with tracking active after recording the tracking-off baseline. The tracking-on value is the one to enter in OBS for AI-tracked broadcasts, while the tracking-off value remains useful for fixed-camera scenes. After applying the OBS offset, record a short clip with the same tracking mode and confirm the clap sound lands on the visible hand impact.

Common A/V sync issues with this model

AI tracking is the defining calibration variable for the Tiny 3. OBSBOT's tracking features can detect people or objects, use Voice Tracking, and move the gimbal to keep the subject framed. If tracking is active during the clap, the video transient can include both your hand motion and the camera's reframing motion, which makes the luminance detector harder to interpret.

Capture mode and Center app state

The second issue is the capture mode you leave active. OBSBOT Center can control imaging settings, avatars, multi-camera setups, and production tools, while the browser receives the active camera stream through the platform media API. Calibrate with the same tracking, zoom, and resolution settings you plan to stream with, then copy the resulting OBS value into the matching OBS Video Capture Device setup.⁴

During the five-clap run, keep the camera mode fixed. The browser test measures the active camera stream, not a separate Center preview, so any change in tracking, zoom, or resolution mid-run shifts the reading you copy into OBS. Close OBSBOT Center before loading the page so the gimbal stays parked and no preset change interrupts the measurement. Use the tracking-off value for fixed-camera streams and the tracking-on value for broadcasts where AI Tracking 2.0 stays active. Match the mode to the stream.

What the test covers

With tracking disabled, the Tiny 3 provides a fixed camera stream for the luminance detector. Five clap pairs produce an average offset that represents the camera-to-browser video path plus your selected microphone path. The result is a single millisecond value you enter as a negative Audio Offset in OBS, which shifts the microphone track earlier to align with the delayed video frames.

If you stream with AI tracking enabled, capture a second measurement with tracking active after recording the tracking-off baseline. The difference between the two readings tells you how much your particular tracking setup changes the measured offset. Use the tracking-off OBS value for fixed-camera streams and the tracking-on value for streams where you deliberately leave AI Tracking 2.0 active during the broadcast.⁵

Independent review testing found OBSBOT Center exposes extensive per-frame image processing, including separate manual curves for shadows, mid-tones, and highlights, on top of the gimbal-based AI tracking itself.⁶ Even with tracking off, OBSBOT Center's shadow and highlight curve processing keeps the Tiny 3 above a minimal-pipeline webcam during calibration.
