I am doing some green screen shooting with an HVX and there is some noticable noise in the picture. The picture looks soft with faint artifacting motion in the picture. I know the key controls need some tweaking, but I see some in the source too.
Is there a best profile, setting, video format for this kind of use? What have you had the most success with?
Here's a link to a test file split with the key and source. Its 160MB and is in full HD format (5 seconds).
I asked for best settings a couple of weeks ago and received great advice, I also made some tests, but with an HPX-170. The two Cinelike gamma modes were the noisiest, B.press was the one with the lowest amount of noise.
Detail level can change the way you see noise in your images. There are different controls for it: the detail level, vertical detail level and the core detail. Test lowering your detail and vertical detail a little. You can have a high detail level if you want a crispy image, but then you need a positive number in the detail core. The core is like a threshold value for the detail to show up.
My tests were not for green screen, but I liked a detail level of +3 with the detail core of +2. Vertical detail on +2. I use those settings now as a starting point, but you should do your own tests (my camera is different). The light on your footage looks fine to me, so check if you're using a Cinelike gamma mode and change it to normal or b.press.
Keylight have an option for softening the edges of the mask, if I remember well it's called "edge softness". A value of 1 or 2 can improve the look of the key by softening the jags of a noisy image.
I hope this helps.
