I know I already have a "post your Vegas creations" thread, but I figured I'd make one specifically for HDR so that people who are looking for HDR demo content do not have to dig through pages of posts to find some
Here is a collection of timelapses I shot (except the first 2, a friend I trained how to do timelapses shot it, and did a fantastic job!!!) and then edited into HDR using Vegas 16, which I should note was far easier, faster, and produced far better looking results than trying to do the same thing in Resolve. To be specific, just so you don't think I'm fanboying out on Vegas here... Resolve had an issue of introducing noise into the image, might have been a GPU bug, but after tweaking the colors for a while I started seeing random colored specs of noise in my image. Also, I was unable to do noise reduction unless it was at its bare minimum settings, or it would say I had insufficient GPU RAM (4GB). In Vegas I was able to get it colored quickly and was also able to use Neat Video for noise reduction on those long exposure shots, which worked amazingly at cleaning things up without butchering detail.
That said, it isn't perfect (though the problem is on my hardware's end, not Vegas'). What I see isn't what I get, as windows doesn't do HDR properly. Windows 10 HDR seems to be a fake implementation, as HDR gradient tests show far more banding than they should (GTX 970s also limit 10 bit output to full screen if I remember right, that may have something to do with it, though I am using full screen preview on my HDR set) and Vegas does not yet support my BlackMagic Mini Monitor 4K, so the video is coming out darker than it should.
