Just wanted to say I used VP this week for a VERY high profile rush job, and it worked brilliantly. I continue to marvel at the genius of the original Vegas interface, and how rapidly, effortlessly, and intuitively it allows you to organize, arrange, and shift clips and audio on the timeline. I could not have successfully processed such a massive project in any other NLE in such a short span of time.
Vegas is, truly, a work of art.
Some things that made a big difference:
For the first time, I let Vegas create proxies, and did all my editing and playback (except color, of course) in the Preview-->Full mode rather than Good or Best. I also worked only in 8-bit mode, including render.
That made a huge difference, allowing me to work with virtually none of the normal (and near-continuous) crashes I otherwise encounter in large projects.
There were still a number of Vegas glitches, to be sure, but they did not significantly impede my workflow.
So let me just say, as much as this program drives me crazy (and it is indeed a disaster in 10-bit mode w/HEVC right now), I do love it, and can't imagine using anything else. :)
