Practicality of S-Video out

[Richard Alvarez]

I've hear anecdotal reports... (Perhaps even via Adam Wilt?) That you can pull a better green screen off the S video connection. Might want to do a little compositing and see how the two hold up.

I also switched off the custom presets so that there is no (or minimised) in-camera processing. Sorry about the shadows - my camera position was constrained due to the length of the YC cable attached to my PC, and also the black cat around the legs of the tripod.

From what I can see, I have doubts whether the YC output is uncompressed after all. In any case, based on the small differences I can detect, I think I actually prefer the DV image.

I can't see a significant difference between the two. And if there is I'd say it's pretty negligable.

I didn't see significant difference either, just visible difference in certain aspects of the pictures I saw.

I would expect there to be differences in quality between various analog capture methods also.

I can't find those emails at the moment and I never posted them because the sender had lifted them from a commercial ad and didn't have permission to pass them around.

actually, in this second one, I see less noise on the left speaker on the YC than the DV and also on the cabinet beneath it. I also see less CA on the left speaker's white area.

Hmmm... If i had an analogue capture card I would try some out...
