Hi, im trying to render my video essay in Sony Vegas Pro 17, Im using a Ryzen 2700x and a Nvidia RTX 3060ti FE on Windows 10. the preview is perfect and I can view the whole thing with no issues in the preview window, when I render it, it renders perfectly fine, when I view the video in the media player of my Windows 10 PC, the video starts out normal but after around 20 seconds it speeds up to about 8x the speed and the audio stays the same. So instead of having an 8 minute long video, i have 8 minutes of audio but the video is extremely sped up, I have no idea what to do.

Thank you.
