    Four Crops. One is DVCproHD Straight to P2 and the other HD-SDI to ProRes HQ 422 fed into a Kona capture card.

    Both 720p24p

    They are all too tiny for me to see any detail at all! But I'm gettin' old!

    They're sections out of the 720p. Not blown up or anything, just pulled two elements that showed the obvious resolution bump.

    Expand them if you can't see.

    1st is P2, 2nd is SDI. Not surprising given the 720p's prefilter. Another reason why I prefer 1080p over 720p on the HVX/HPX170.

    Indeed it is. I was actually a tad bit surprised to actually 'see' it right off. I would like to say that it's negligible but when I think about how much "sharper" or resolute the A1 is and that was considered negligible, I kind of want this.

    Going to try 1080 but I expect to see even less of difference.

    Your 1080 DVCPRO-HD should look ever so slightly sharper than your 720p SDI grabs.

    People who say there is no difference between the 720 and 1080 just aren't lookin' at the same thing I am...

    Oh I meant 1080 through HD-SDI. I know for a fact that the 1080 DVCproHD is the better way to go when you have the card space. I'm going to grab a long HD-SDI cable and head outside as soon as I finish a chunk of tapes.

    Yeah I bet you'll see little if any difference between recorded 1080 and SDI 1080; maybe a little but not much.

    Heres the thing I don't understand, though:

    Why does the A1's 1080p look more resolute than the HVX/HPX's 1080p if it's only a few lines more?

    1280x1080 vs 1440x1080

    And, if that's the reason, why am I not expecting some A1 flavor or just SLIGHTLY better 1080 out of the HPX's SDI?

    I already know not to expect it, I still can't figure out why.

    I still don't agree with the assertion that the A1 looks all that sharper. In my HVX vs. A1 test, I saw maybe, at most, a 5% difference.

    But, assuming that you did want to think of it as being sharper, the question is 1080i or 1080p; in 1080p mode they're very comparable. In 1080i mode the A1 will be sharper because it's dealing with 1080 vertical pixels, vs. the HVX's 810 lines.
