After rendering, the audio track is offset by 65 milliseconds

Below are the cut pieces of video. Above is the rendered file. The videos are currently synced. But the audio track is out of sync (no stretching or tone shifting effects). Below is a music track without any special features.

I checked and rendered the finished file (the one above). Then I opened a new one above it (they have the same settings), and it is also out of sync, as if Vegas shifts the sound. Does anyone know what to do with this? This completely ruins the video and makes it unusable for output.

Are you using any noise reduction plugin? I previously had one third party plugin that shifted audio a few milliseconds, but not 65.

Which render template are you using and what GPU? My experience is this can make a difference of a few frames which is probably more than your 65 milliseconds.

Plugins are all disabled

Какой шаблон рендеринга вы используете и какой GPU? Мой опыт показывает, что это может иметь значение в несколько кадров, что, вероятно, больше, чем ваши 65 миллисекунд.

Это видео уже отрендеренно. У всех файлов один проект и параметры.
Я провела тесты. При использовании Mainconcept AVC мы получаем рассинхрон. Если выставить NV, то все нормально становится.



Проведено 4 теста. Все подтверждается.


Но раньше такого не наблюдалось. Хотелось бы выяснить причину.
