Would you mind letting me know what settings you use for standard DV in Vegas 6.0a and later? I would appreciate it as I am not exactly sure what they should be. I think I do, but then there is nothing wrong with being sure.
I had the same question regarding HD, which I put to Caymen Graphics. CG said "Power CF RFS does not support HD."
Regardless, using the Gearshift proxy I've dropped a coupla CG RFS titles in and it doesn't look too bad. I'm sorta trying to get an understanding of the impact of HDV on Bluff Titler, Wild FX Pro, Power CG RFS, Cool 3D, Particle Illusion, and Spicemaster, since I have them all.
With regards to the Pixelan stuff, and Cool 3D, not to mention the Cayman tools, they will "manage" HD footage, but the colorspace is at issue. All the tools are 601 compliant, whereas HD is all ITU 709, so there are some color issues.
Render a short segment using the Spicemaster tools on one half of an HD clip, and you'll see a color difference, albeit a small one.
