Hey guys I really need some help. I'm trying to render a video I filmed through Sony Vegas but whenever I try to save my video as an avi file type it makes it into some random sfk file. With an sfk file I can't upload the video to Youtube or even watch my video! I've spent at least 5 hours trying to fix this I've even tried to use some new video editing programs but nothing's working. If you guys know how to convert this sfk file to an avi file please help me.
