Whenever I place a file into the timeline (I'm using MP4) the audio starts unsynced. (maybe by a second or two) But not all videos, just some. Some are longer videos up to 4 hours and others are as short as 10 minutes but I've had random ones have the same issue. All the videos are recorded the same way with the same format. I use obs 22.0.2 and record under MP4. I use my cpu as the encoder with the screen resolution 2560x1440 at 60fps. All audio being recorded to different tracks. (for example: Game audio, mic audio, desktop audio)

The audio isn't misaligned, it is perfectly matched with the video and it works perfectly fine when played through any other media player including the older version of Vegas Pro 14 that I had.

The only thing I have noticed is that it seems the video itself is skipping over or loosing frames? During the preview I notice that the video goes to black and then comes back 1-3 seconds later even more misaligned than before. The original video not having any kind of skips, just when in Vegas Pro 16.

I'm running Windows 10 (Latest version as of this post)

Asus ROG gtx 1080

i7-7700k intel processor

16gb corsair Vengeance RAM

MSI Gaming m5 Z270 motherboard

I'm not entirely sure what/if any info would be needed from Vegas but I'll be more than glad to add those if needed.
