Am I wrong (or crazy) for wanting to unload my Z1u?

I believe what they are saying is that the image is internally processed by the camera at 1920x1080. But when you record to tape, it will be squeezed to 1440x1080. The playback device then understands to stretch the image back to 1920x1080.

Something similar is done on the XL2 in widescreen mode. The CCD's use a 960x480 array, but 720x480 is written to tape, which is anamorphic 16:9 standard definition.

Look at the page about the CMOS sensor on that same site: http://bssc.sel.sony.com/Broadcastan...U/devices.html Here you will see that the sensors have 960x1080 effective pixels. The EIP chip interpolates the data from the chips to create a 1920x1080 progressive image. Then it's scaled down to a 1440x1080 4:2:2 interlaced image which is available through the analog component video jacks. Finally it undergoes the HDV compression process before being written to tape.

Never mind--this I don't get.

See the following: http://dvinfo.net/canonxl2/articles/article06.php

Don't confuse the resolution of the image sensors with the format of the data written to tape, they are frequently different! All standard definition DV is recorded as 720x480, regardless of the number of pixels used to capture it. Likewise, 1080i HDV is always 1440x1080 to tape.

exactly, which makes the fact that a 1920x1080 signal exist somewhere before it's recorded pretty much irrelevant. more or less a marketing 'lie' rather than anything else.

It isn't a lie. Pixel shift with non-square pixels makes it go to 1920x1080. Does the HVX200 with its 960x540 sensor make it a 'marketing lie,' as well, since it goes to 960x720 and 1280x1080?
