Kona 2 HD to SD down convert colour reliability
Hello there,
I’m using a Kona 2, editing a DVCProHD sequence, monitoring with a Sony PVM14 (SD-Component) using the down convert function of the card and also monitoring with an Apple 23″ Cinema display (through an AJA HDP converter). Can I trust the down convert output to my SD monitor for colour correction? The NTSC bars seems fine, but how’s is the down conversion performed by the card? Is there a loss of colour fidelity? I’m using the Apple display as a second monitor display only, noy for critical fine-tuning. Can I trust my SD (CRT) monitor for
critical work???Thanks for your input.

you realize these are two different color space?
so your final output is SD?
basically, the card has conversion chips on it. there is no loss of color fidelity, the color is accurate sent to the display as far as what is being laid off to tape. bear in mind, the color is being converted from HD to SD space.
that monitor is about as accurate as any sub-$1000 display today, maybe better.

“…and better than an Apple Cinema Display.
Sup uncompressed? I am speaking engrish all over the place.

It’s perfect, but you’re working in two different color spaces. HD color is not the same as SD color. So your color grading will be spot on for SD, but you’ll lose something in HD.
If that’s all you have available to you, then it’s better than nothing, but the only way to accurately grade HD is with an HD Reference monitor.

I understand they are 2 different color spaces. BUT what are the
actual differences between the two (besides the obvious image size
differences)?Thanks
