I am having an issue with a few of the files (not all) I imported for an edit - where they will at sudden points have then audio and video become out of sync in the video clipper as well as being stand alone in a project. I doubled checked the mp4 file source they come from and they play without any issue on every media player Windows has so feel safe to say its not an issue with the original files. I've also tried making sure the frame rate for the videos and the project are the same, and tried re-importing the files to see if it was some kind of error originally but neither helped. I am using Vegas pro 23 that is completely up to date on updates as per the update search option (on Windows 11 also completely up to date)

Any help would be greatly appreciated as I'm losing my mind trying to manually sync intricate audio/videos for every clip I want to add in. This is killing my OCD!
