I spent a while editing a 40 minute video using Vegas Movie Studio 16, i set it rendering last night and when i woke up and watched it, it was filled with areas where the video was missing and replaced with a black screen however all the audio was still there. I've tried rendering it multiple times and the errors seem to appear in somewhat similar places but i have no idea why this would be happening. I've tried disabling resampling on all of the videos and unchecked the box in preferences which says "close media files when not the active application" as that is all the advice i've been able to find online. I've tried rendering it into 2 different formats and both have the same issue. Please help if you have any idea what the issue could be :(
