I am new at Sony Vegas, and just getting the hang of it, when - I think I clicked on something - the Video FX options do not work like they worked before. I wanted to blend a video with another one, then I wanted to desaturate the top vid. But it only does the edges!
I didn't use the 'desaturate' option, but the 'cold' one.
It's not like I want to go pro on this, but I think fanvids are an excellent way of improving my video editing skills.
