Sony GV-HD700 High Definition Video Walkman ReviewThe product pretty much does what it says, and does tape in HDV from the Firewire input. There were some minor issues connecting it to FCP 6.02, but suddenly, magically, it worked.Screen Spec: Sony (and most sites) say "1152K pixels" leading one to believe that the screen is 1440x800. According to a quick test by me, that is NOT the resolution. The manual says 800x480 (384,000 pixels) and that is likely correct. Sony gets the"1152" by taking 800H lines x 480V lines x 3 colors = 1152K. No one else I've ever seen, including Sony on other products measures resolution this way.To check it out further, I used a resolution chart and fed the FW output (HDV) to Quicktime to view on my Apple 30" display. Resolution to 800 lines, both H and V resolution was limited by the camera (which is about 690H 650V according to some tests by [...]. When I looked at the same output on the GV-HD700 display, Vertical resolution topped out at about 400 lines, Horizontal at about 600 lines, confirming the 800x480 spec in the manual.There is considerable delay when inputting to the GV-HD700 using Firewire HDV signal, so its use in the field as a focusing aid is problematic. The screen resolution is better than the ones on a camera (my V1U has 960x220 according to Sony), but the delay (about 1/2 second or more to decode the HDV signal) means that on other than stationary objects, it is useless, and even on stationary objects, one must be patient to get the focus right and avoid overshoot. But since the screen is really only standard definition anyway, if you let the GV-HD700 downconvert to DV for firewire output, the delay is quit short and the display on the screen is essentially the same as when using HDV.I still give it four stars, because other than the spec issue, HDV delay is to be expected, and it is a much more cost effective deck than any other, like the MS10 or 15.Suggested enhancements (that is, cool features missing): 1. real HD display; 2. HDMI input for at least display purposes to minimize display latency for monitoring; 3. Component input, same reason as #2.Sony GV-HD700 High Definition Video Walkman Overview
