For the clearest explanation of why the PDX10's 16:9 mode is superior to that offered by its less expensive brothers
Nice link, thanks Michael.

and here is another illustration..

- Idle thought - does the PC330 with its 3MP CCD do 16:9 better than the PDX10?

That explanation is true for a TRV950/PDX10 comparison, but not for the TRV70 and TRV80, at least.

Both gain their 16:9 ratio in the same way as the PDX10 (i.e. expanding the sensor area sideways rather than cropping vertically). But they only single-chippers, of course.

Tommy's link is actually slightly more truthful than Michael's as the admission is given that in the 16:9 mode vertical resolution is indeed sacrificed when compared to the 4:3 rectangle.

My own filming tests show that the 16:9 uses 10 per cent fewer vertical CCD pixels than 4:3 mode but 20 per cent more horizontal pixels (see the diagram on Tommy's link). In a perfect world the vertical resolution would remain unaffected and the horizontal pixel count would increase by 25 per cent, but this PDX10 solution is certainly a step in the right direction.

Good news for the upcoming Panasonic NV-GS400 as its claiming that no vertical zooming is necessary for its 16:9. Its also worth pointing out that the GS400 has almost an indentical CCD/pixel arrangement as the PDX10. 1/4.7" 3CCD with 1070k each

FWIW, "Tommy's link" is the same illustration found on page two of Sony's PDX-10 brochure.

Hmmm. According to the Sony consumer web site, the TRV950 (same optics and sensors as the PDX10) actually has less pixels per chip.

"1/4.7" Advanced HAD™ 3 CCD imagers with 690k gross pixels each" and "1.0 megapixel gross" referring to the whole array, not to each CCD :-(

http://www.sonystyle.com/is-bin/INTE...ycamCamcorders

Confusingly, the Sony pro camcorder website lists the PDX10 as having "High Picture quality with three 1/4.7 inch CCD sensors with 1,070,000 pixels each"... then again it also says the camera has "reduced vertical smear" and 15 fps proscan which we all know it does not have, at least not in video mode:

Click on the specs of TRV950 and you'll see that it shares the same CCD/Pixel arrangement of the PDX10.

1.4.7" 3CCD with 1070k pixels per each CCD.

It is confusing how they state the 690k video gross pixels though.

I believe if you read the fine print somewhere it states that figure is for 4:3 mode....
