I should have read a little more. camcorderinfo says that the 16:9 mode is digitally altered so thats that. it is an utter waste of the extra resolution on the ccd's. Effectively you could say that because the are used on the ccd's is less then the effective, then they may as well be smaller than 1/6 inch.

in response t Pal vs NTSC resolution

one thing to note is that PAL is generally a higer res with a higher peaking colour than NTSC... res is anythign between 20k to 40k pixels and our legal broadcast colours are slight more "flexible" so contrasts are a lil deeper (generally speaking)

PAL - Perfection At Last. :-))

The GS120 and GS200 lack optical image stabilization and use pixels on the CCD for its digital image stabilization. That pretty much rules out a HQ widescreen mode. Some cams disable image stabilizatoin altogether while in 16:9 mode since they are both vying for the same CCD pixels.

thanks for that tommy. it only takes a little common sense to nut that one out doesn't it. does this mean though that the image stabilizer on these cams are going to be much better then before. wouldn't that be great. that was always the biggest thing against the gs-70 separating it from the 500. apart from 16:9 of course.

NTSC can actually produce better colors than PAL. The problem of shifting color was only in analog broadcasting. If video cable was used there was no problem and today with digital recording and broadcasting the problem is all gone.

Contrast is the same as DV always records at 0 ire. It depends on how the display is calibrated.
Many people do not realize this but you get exactly the same pixel count per each frame both in PAL and NTSC. PAL has higher horizontal resolution but NTSC has higher temporal resolution.

Here are the numbers:

NTSC 720x480x30=10368000 pixels
PAL 720x576x25=10368000 pixels

Thanks, Chris.

But why do people say, "NTSC, never the same color." :-))

Frank, that'll be the "Rose Tinted Glasses!"

As I mentioned this was only a problem during early days of analog color RF broadcasting. Basically color subcarrier would shift in phase so when you went from channel to channel you would have to adjust hue. This was mostly eliminated when manufacturers started using transistors and IC's in TV sets.

If you went baseband video directly into monitor this problem never existed as there was no RF subcarrier. Nowadays with digital broadcasting this does not exist as there is no subcariers just data bits.
