Audio ahead of images video recorder

I'm using video recorder to record a presentation video for my game.

The images flow well, there is no lag so I don't think there is a problem regarding the power of my PC.

The only problem is the audio, which comes before the images. I looked online for a simple program to synchronize it, but I couldn't find it.

And anyway I want to know if I can solve the problem.

Do you have any ideas?

I have the same issue. It's quite annoying.

I think I solved the problem:

the "audio codec" item should not be selected to "auto".

I selected opus and it seems like audio is as the same time with video.
