Also, I'm curious about "Cineform neoscene".
they claim:
"Chroma Interpolation: 4:2:0 → 4:2:2. Background: Most HDV and AVCHD camcorders record chroma (color) in a format known as 4:2:0. Without boring you with details, 4:2:0 chroma is half the color resolution of more professional 4:2:2 formats. When Neo Scene detects 4:2:0 chroma it properly interpolates the source chroma to 4:2:2 for more accurate color processing during editing and effects work. And if you ever "key" your material, CineForm’s chroma interpolation will substantially improve your resulting visual fidelity."
Anyone converted some of their 5D MK II footage to 4:2:2 in this manner? I'm wondering if it will hold up to grading better?
