I have to give credit where credit is due. The first serious draft of my Garden project finished rendering this evening in Vegas 13 - on the first try and without a hitch.
On the other hand, Vegas 12's latest build choked on several of the files and I couldn't proceed on my main edit computer, which didn't have Vegas 13 installed. I had been afraid to risk an upgrade, so I left my main rig alone until I finished the draft. When 12 crashed repeatedly while trying to load the files, I tried them in Vegas 13 on my everyday system. It didn't have a problem, so I installed 13 on the edit rig. I didn't have any more problems getting the project assembled.
I dropped the rendered L/R video files and audio from Edius into Vegas, added chapter markers and let it burn. It still needs considerable tweaking (especially audio), but it feels good finally to have something I'm relatively happy with. Of course, it's a niche subject that won't appeal to a lot of people. Avatar it ain't.
However, I think people who are interested in horticulture and/or iconic cultural institutions will find it worthwhile. At about 1:20 in length, and at 25 mbps, it takes up only half a 25GB Blu-ray disc. The quality still looks quite respectable, because almost every shot was taken with the JVC TD1 set to MVC mode at 34 mbps. However, even though I shot with slow pans and tilts, I slo-mo'ed many shots so they wouldn't blur or judder unacceptably. That makes it more static than I'd like.
