Re: What about HD Camcorders

As far as I understand, the current generation HD camcorders (those
below $10K) cannot resolve more than 600 single lines in vertical
direction. Which, essentially, means that downconverting to the DVD
(e.g. 720x576) format would lose only a minuscule amount of video quality.

Judging by what you wrote, your video playback hardware does not
support playing higher-than-DVD-resolution MPEG4. So, for the time
being, you better store the original contents (until you upgrade your
MPEG4 player), AND store the downconverted DVD for playback NOW.

Hope this helps,

The ones I have been looking at have 2M pixels still picture and a claimed
1920x1080 CCd. I had presumed that this type of camera is a true HD
camera.

A "true HD" prosumer camera of today STILL produces images only
slightly better than what a DVD can store. As you know, the sensor
size gives no information about the image quality. The data point of
resolving 600 single lines per picture height is what matters (I took
it from the reviews of below-$10K cameras of 2007).

Remember that with a good up-converting a DVD image may "look
extremely good" (whatever this means ;-). And yesterday, inspired by
this thread, I found that "Planet Earth" (which everybody is raving
about as a reference point on "how good HD could be") was shot mostly
with 1280x720 and 1024x576 sensors (but they were 3ccd 2/3").

Hope this helps,
Ilya
