To mention cross fades proves to me that you don't get it.
No, I think you may not quite get why I bring it up.
As I've said several times, these things are true in Premiere. They are not true in Vegas. (There is no tool bin.)As I have already stated every time you use the trim editing tools you must reposition the cursur to view your edit. Obvioulsy to make sure to don't have a funky jump cut. You must always switch between triming tools with keyboard short cuts or select the tool from the tool bin.
I know, which is why it makes the trim editor a great tool for Premiere, but it's not needed for Vegas. Anything the trim editor does is simply done in a different way.All this is eliminated with the trim editor.
