Hi there, hoping you guys can help me because I'm seriously struggling! I'm relatively new to both video editing and sony vegas, and I've tried everything I can to resolve this problem.I'm running Sony Vegas Pro 9.0, my computer has an Intel Celeron single-core 2.20GHz processor and 4 gb of ram, and I'm running Windows 7 (not the most powerful set up, I realise)My problem is that if I render multi-screen video at preview quality, it's fine, but if I render as 'Best (Full)', or even final render out as an .avi file, then some of the screens come out as white. I'm running 5 video tracks, 1 audio track. 1 of the video tracks shows, and the rest do not. All 5 video tracks have a border effect on them.render problems.jpgNot sure why this is happening? Rest of the video is fine, only seems to be when there is 5 videos at once. Is it a memory issue? Something else? How do I fix it!
