Noise into color banding: will 32bit f.p. help in Vegas Pro?
Posted: Fri Aug 20, 2010 11:06 am
First time poster here, and a new NV user in Vegas 9 Pro !
First impressions are OK, even though it's sooooo slow With my EX1 or nanoFlash mxf files (full HD in 4:2:2, at 35 Mbps and up), it renders at some 2 fps on my (little old) QX6700...
A couple of questions:
1. In my result clips I can see occasional color banding which are not present in the original, 100 Mbps 4:2:2, L-GoP files. I'm told the noise acted as sort of dithering thus effectively preventing the color banding, so removing the noise caused banding to show. I tried and converted a particularly noisy clip to 10-bit Sony YUV intermediate, and tried NeatVideo on that...
Well - it looks to me NV cannot take advantage of the 10 bit color: in its configuration preview window, the frame is still reported as 1920x1080, 8-bit RGB.
So, does it make sense to use a 10bit intermediate?
2. Will it make a difference if I set my Vegas project to 32 bit floating point?
Thanks,
Piotr
