Screen shots from JAG

You'll remember I stated the Z1 shots were soft and the Z1 shot of the boat was out of focus. I've now found JAG shots that show this clearly.

First HDCAM: http://www.nabs.net/Personal/Jeff/Movies/Capture/JAG0218-04.jpg

Now Z1: http://www.nabs.net/Personal/Jeff/Movies/Capture/JAG0218-03.jpg

Note the extra "ghost" to the right of the gunsite and to the left of the front of the boat. Watching 1080i HDV frame by frame I often see a displaced color image. It is often red.

You can this to the left of the white wake from the very out of focus boat:

Simply compare the first pix (HDCAM) to the third (1080 HDV) and you can see the huge quality difference.

Now it may be that the oroginal HDV does look better which is what the guy showed at Sundance. Thus what this may show is the degredation of sending 1080i HDV through several steps of compression: HDV >> HDCAM >>> D-5 or HDCAM-SR >> MPEG-2.
