Two questions about amateur film resolutions



Frage von Timo:
Oktober 2005

Hello,

I have a standard mini-DV with a CANcorder Resolutionvon 800.000 points. with the dvd-standart of 720x576 pixels, I come to a large number of approximately 400,000. at a resolution of 1024x768, this would be about 760,000. the loss of image stabilization, and another 400,000 pixels can not be!

two lay ask

1) is with the current dv to dvd-standart qualitatspotential yet given away?
2) if so, can it with the new technology has hd Vorrausgesetzt yet in retrospect, one of the original dv-recording yet to receive?
Keywords Hd-dvd and hd-kodec!

Thank you very much
Timo



Antwort von RuFFi:

how naive to assume that only every second pixel on the CCD chip is supposed to work.
Clear all working Chips and it is downscaled in the DSP, the average of two chips or more chips will be very mathematically formed so that s.Schluss a PAL digital signal comes out.



Antwort von Stefan:

As one can expect synonymous different:

720 pixels X 576 pixels * Y * 3-pixel-per-primary color (or brightness and 2 Farbinfos) = 1244160 for a 4:4:4 sampling

THAT would make the best ;-) But HDV is not synonymous, but 4:2:0 sampled synonymous and need less pixels.

Some specialists offer specific s.eine convert HDV or DV camera so that a full 4:4:4 analog signal comes out. With the corresponding 4:4:4 capture card so you can then use synonymous.

Away is on the way DV to DVD a lot. Compare the bit rates (DP: approximately 3.5 MB / s into DVD about max. 1.35 MB / s).

To HD-DVD, I do not know the details regarding the allowed video bitrate. I hope that may be higher than that of DVD. Therefore less lost in the conversion of DV to HD-DVD's than DV to DVD. If you want to synonymous, you can sign a petition about this: http://www.petitiononline.com/cehddvd/petition.html

Good luck
The fat Stefan

the kite fields DRAKE camera project is a self-developed digital camera, but have read somewhere that is said to have divided the team.

the andromeda project sounds pretty interesting. apparently they want it now synonymous with a canon xl2 test.

wär schon geil in my xl2 camera with a Mach hs abtastung to 4:4:4. obs for pal synonymous equipment is not feasible (in Amerka) I know.
use (but apparently einife american. filmemacher pal cameras, higher resolution because of the low!?)
'm only a few days on the site encountered - stay tuned to each instance.
let's see
