Thank God I found the solution

Make a delay for the video and the result is good

But when the delay is increased, the result is better, but the program stops working and a screen appears

What's the reason ??

It looks like you’re putting a negative (minus) delay on the video? Once you go past the internal frame buffer in Aximmetry you would have to be able to predict the future to add more delays. The correct way to do it is to add a positive delay to the sound instead.

The video precedes the sound. If the value is positive, the delay will increase

Do you mean the audio comes after the video? In any case, you must apply a positive delay to either the audio or video to match them. You’re currently applying a negative delay to the video which won’t work. You will get the same end results if you apply a positive delay to the audio instead.

Dear Hussen,

as Twenty mentioned, you need to add a delay to your Audio to avoid that issue.

You can try to play with the Delay property of the audio until you find the right settings (since -7 video delay worked for you a +7 audio delay should work theoretically).
