I’ve never had crashing problems with alot of Sony Vegas FX, but NewBlue is a third party effects package and maybe that’s causiing the problem. Do you have any other versions of Vegas you can try? I get crashes with different versions. Like Vegas 9c will render a 1920×1080 60p .WMV and .MP4 where 9e will error or crash. Ver 10 64 bit renders these files without problems. You could always do it in parts, so to speak, like use half of the NewBlue fx, render to a lossless file, then add the rest of the effect to that new file, in case it’s a CPU or memory issue that’s causing the crashes. Hope this helps, Danny Hays
