What kind of TV program? A football game or a letterboxed movie will make a big difference. Also depends on how it is encoded, interlaced or progressive? Use of filters? And also the quality of your source will make difference. Digital or analogue cable? Blocky or noisy source?

We could compare if it was exactly the same TV-show or maybe the same DVD movie. Do you want to compare capture cards or encoding methods?

You can grab digital cable TV with a DVB-C card.
You can rip a DVD from a DVD-ROM.
You can capture DV8 through firewire.

Anyway your Q-levels seems good so I guess you have nice quality captures? What are your peak Q-values? I think 4300 kbit/s VBR should be enough bitrate for almost everything when capturing at half D1.

Hi,

My Cable TV is analog and my ATI 7200 cannot capture Firwire DV8. I use 1/2 DVD to get 2 hr movie to one DVD+R/RW.

And if you are Useing a Cracked version of "Bitrate Viewer" it will Intentionally give you False readings....I Get Much Better Quantization when useing a Real Encoder as opposed to MMC...

Hi,

Yeah, ofcourse Dazzle and other hardware analog/digital converters give good quality, but HOW GOOD?
And what is Q.level of better ATI AIW's let's say 9000, 9600 ??
ViVo's aren't usually any good !

Crappy Quality and a High Quantization level

January 4 2004, 4:33 AM 

Hi,

Well, eh!

Without watching mpeg You can tell Q. lev 20 is nothing but blocks. Q. lev >10 is miserable and Q. lev 1-3 is just fine.
