HD-1's top row chroma loss
 
The top row of our HD-1 camera seems to have lost its color, although since it's only one row it's hard to say. Has anyone else experienced this problem? I'm viewing the image on a standard def 32" Sony so could it be just be an artifact of the dividing line between the frame and the black bar? Also, there seems to be a little more overall frame showing at the top of the screen on the TV than on the cam's flip-out screen--has anyone noticed a slight cropping difference?

Betsy,

You're right! The screen does not show all of the top. The bottom is a bit closer to reality. (on HD10). Haven't checked the sides closely. All the LCD camera screens I have seen seem to crop a bit.

How does the top line show on your editing monitor?

Same problem
 
I just noticed the same problem when I view footage from my HD1 on my plasma tv. Bizarre!

Any thoughts on what causes this?? Or is it just a quirk of the camera?

Not sure if...
 
...we're talking about the cropping on the LCD or the loss of color in the top row, but...

On an NTSC monitor, i.e. std-def tv, the top row is the VBI, (vertical blanking interval), where closed captioning, screen format and other info can be encoded. A loss of color or image there is normal. You usually won't see it on a tv, because they build in a bit of overscan. With editing software, or when viewing the whole image on a PC, you will notice it.
