I encode a lot of DV NTSC video for the web. I've been told that the best way to improve DV NTSC color sampling (4:1:1) for the web (4:2:0) is to render it using a (4:2:2) codec like MotionJPEG and DV50. I use Premiere Pro 1.5 and Final Cut Pro to capture, is there a way to change the color sampling of DV NTSC upon capturing? Or is there a compression software that will adjust the color sampling before encoding?
And rerendering from 4:1:1 to 4:2:0 doesn't help. What does help is to render from an NLE as 4:2:2 when using 4:1:1 source, so all effects, motion graphics, titles, etcetera get rendered as full resolution.
DV25 should only be treated as an acquisition format, not a post format.
