I've been using Vegas for a few months now but I only use the basic editing and effects tools nothing special so i'm not brilliant with it.
When I import videos in and add a sound/music file I don't usually have a problem, preview and render with the final video looking just how I wanted.
Recently when I add videos the colours seem to blur and sort of appear as boxed and really bad quality. This happens at the more action/colour parts, it only appears for 1-2 seconds but every so often and ruins the videos. I've never had this problem before and have no clue how to prevent it. As well as this (although not a big issue I just avoid adding effects) if I add some effect like lense flare etc the video will move slow and stutter while the effect persists.
Has anyone had any experience with this issue? Help is really appreciated so I can get back to making more videos
