So i've had this problem with a few video's now. I record the video with OBS and then throw it in Vegas Pro 15. But every time the video seems to like just completely destroy itself. I've captured a few screenshots and put them in https://imgur.com/a/w2zcAGd this album so you can see what I am talking about. If anyone has any idea why this happens then i'll be happy to test them!
EDIT: I need to add that i was using multiple audio tracks in OBS with an output as an MP4 file. Perhaps that's whats messing up Vegas Pro?
