Effective pixels. 340K or 690K?

by vicf23 / June 21, 2005 5:08 PM PDT

Hey,

I just started looking at some camcorders, and I was wondering if there's a large difference in video quality between a camera with a 340K CCD or a 690K CCD.

From what I gather, NTSC is 720x480, or 340K. What advantages is there to shooting at 690K if its only going to be down-converted?

Thanks,
Victor

Over at some review sites such as dvspot.com there are example video for you to review.

And you are right. NTSC is pretty ratty stuff.

NTSC is 720x480-NOT
by jcrobso / June 22, 2005 1:05 AM PDT

NTSC analog is 320x240. DVD is 720x480. When you watch a DVD on a standard analog TV it is down converted to NTSC 320x240. If you have a HDTV and are using componet cables then the DVD will be 740x480.
Now you need to read the specs carfully there is a difference beteen efective pixials and the total numbers of gross pixials in camera specs. The number also is different for still mode vrs video mode.
Most seen to be in the 290k range for video.
Keep in mind that video camera image quality is rated by
a term called "horzontial resultion" this refers to how much picture detail is on each horzontial picture line.
And is an analog mesurement. For a miniDV camera 400 lines of "horzontial resultion" or higher is expected.
Here is a link with lots of info. John
