Frequently Asked
Questions

How do I use this tool?

Record a short test video with a clap near your camera and mic. Load it here, mark the frame where hands touch, then use Auto-Detect or click the audio spike. The calculated offset goes into OBS Audio Sync settings.

Why are my measurements varying?

Video frames are discrete (33ms at 30fps), so there's inherent ±17ms precision. Take multiple measurements and use the Running Average for best results.

What if I get a negative offset?

Negative means audio is late. Enter the negative value in OBS, or if that doesn't work, you may need to delay video instead.
