5D artifacting on component output
I’m outputting through decklink card component signal going to a JVC-DTV 1080 monitor. The 5D h264 movies were transcoded to Prores 422.
Here’s my question – when viewing the footage via component to the JVC monitor there is substantial artifacting, particularly in the blacks.
When I switch to a DVI output from the tower directly to the DVI input in the JVC monitor that artifacting is way less.
I know the limitations of these cameras to start with. What I don’t understand is the quality difference between component and dvi monitoring. Thoughts?

I recently got some 7D footage in. Transcoded to ProRes LT and there is quite a bit of noise in the blacks. Especially via component to the LCD. VIA hdmi the noise is barely noticeable. Perhaps the issue is with the monitors. A digital connection represents the image exactly while an analog connection, to a digital display, requires some sort of sampling or compression or digitizing of some sort before it hits the screen. If the image is noisy, it might be hard to correctly represent. Should we care? I think so since much if the audience might be viewing it with a similar setup. We plan on retranscoding to 422 or HQ for the final.

Three issues. Firstly what did you use to transcode the 5D footage. Secondly what ISO settings did you shoot with. The third issue of seeing noise in component over a digital feed says to me that your monitor is perhaps a bit noisy. Feed from the Decklink should be clean. There will always be more noise in an analog feed.
